The Montana composite was developed in Brazil from crosses between Bos indicus and Bos taurus and structured into four biological types: Zebu (N), adapted taurine (A), British taurine (B), and continental taurine (C). This study aimed to characterize the genetic diversity and population structure of the Montana composite using genomic data through principal component analysis (PCA), admixture analysis, and Wright’s FST statistic. The PCA revealed a clear separation between Bos indicus and Bos taurus groups, with Montana animals distributed in an intermediate position. The first two principal components explained 69.48
The relationship between diabetes mellitus and prostate cancer (PC) represents one of the most intriguing paradoxes in cancer epidemiology, with diabetic individuals exhibiting a reduced incidence of PC yet poorer prognosis following diagnosis. This apparent contradiction underscores the need for an integrated understanding of how systemic metabolic dysfunction influences prostate carcinogenesis and disease progression. The present review critically synthesizes contemporary epidemiological, mechanistic, and translational evidence to establish metabolic convergence as a unifying framework linking diabetes-associated metabolic abnormalities with PC biology. Current evidence indicates that chronic dysglycemia, hyperinsulinemia, insulin resistance, and endocrine perturbations orchestrate interconnected intracellular signaling networks involving PI3K-AKT-mTOR, AMPK, AGE-RAGE signaling, oxidative stress, mitochondrial dysfunction, and epigenetic reprogramming, collectively driving metabolic adaptation and tumor evolution. Beyond tumor-intrinsic mechanisms, diabetes profoundly remodels the prostate tumor microenvironment through alterations in stromal metabolism, cancer-associated fibroblast activation, adipocyte-tumor crosstalk, extracellular matrix (ECM) remodeling, hypoxic adaptation, and vascular dysfunction, while simultaneously promoting immunometabolic reprogramming characterized by macrophage polarization, T-cell dysfunction, immune checkpoint activation, and immune evasion. The review further examines the bidirectional interactions between antidiabetic therapies and PC treatment, critically evaluating the translational potential of metformin and emerging glucose-lowering agents within the context of precision metabolic therapeutics. Finally, future directions encompassing biomarker-guided patient stratification, longitudinal metabolic profiling, multi-omics integration, artificial intelligence, and clinically relevant mechanistic validation are discussed as essential components of next-generation precision oncology. Collectively, this review reframes diabetes as an active metabolic determinant of PC rather than a coincidental comorbidity and highlights metabolism-centered precision strategies as promising avenues for improving risk stratification, therapeutic decision-making, and clinical outcomes in diabetes-associated PC.
To explore the role of N4-acetylcytidine (ac4C)-related genes (acRGs) in colon adenocarcinoma (COAD) and identify reliable prognostic biomarkers and potential therapeutic targets. Multi-source transcriptomic datasets (TCGA-COAD, GSE39582, GSE17536) and single-cell RNA-seq data were analyzed. Ten machine learning algorithms were integrated to construct an acRG-based prognostic signature (acRGBS). Immune microenvironment (TME) and genomic profiling were performed, with in vitro functional experiments validating TUBA1C’s role. acRGBS, comprising four hub genes (SARAF, CDC42SE2, TSPYL2, TUBA1C), effectively stratified COAD patients into high- and low-risk groups with distinct survival outcomes and was an independent prognostic factor. High-risk patients exhibited increased genomic instability and immunosuppressive TME, while low-risk patients had favorable immunotherapy response. TUBA1C was overexpressed in COAD cells, and its knockdown inhibited proliferation/migration and induced apoptosis. The acRGBS is a robust prognostic tool for COAD, and TUBA1C serves as a candidate therapeutic target, providing new insights for personalized COAD management.
MicroRNAs (miRNAs) of the miR-200 family—specifically miR-141 and miR-200c—regulate neurogenesis, differentiation, and epithelial–mesenchymal transitions in development. Dysregulation of these miRNAs is associated with several diseases including cancer and stroke. The Mirc13tm1Mtm/Mmjax mouse line, which targets the miR-141/200c cluster, was originally generated and described by Park et al. 2012 as a knockout-first, reporter-tagged insertion with conditional potential (conditional-ready) mouse line. Harnessing its full potential requires a two-step breeding process: breeding with FLP mice to excise the lacZ/neo cassette, then breeding with Cre to delete the floxed miRNA cluster (Park et al. 2012). However, many studies either bypassed removal of the lacZ/Neo cassettes and treated the mouse line as Mirc13 knockouts or bred directly with Cre mouse lines, which could lead to unpredictable recombination and genotypes. Here we show that retention of the lacZ/Neo cassette is associated with reduced expression of the neighboring genes Ptpn6, Phb2 and Atn1 in the olfactory bulb, and that these genes are expressed normally once the cassette is excised. We therefore recommend a validated two-step FLPo-then-Cre breeding plan for this line, together with case-by-case allele validation for other knockout-first, reporter-tagged mouse lines.
Long non-coding RNAs (lncRNAs) are emerging as important regulators of inflammatory and immune signaling, yet their contribution to bovine subclinical mastitis remains poorly defined. Here, we characterized the lncRNA expression landscape associated with disease in milk somatic cells of healthy and subclinical mastitic Vrindavani cattle. We identified 11,403 high-confidence lncRNAs, of which 104 were differentially expressed in subclinical mastitis (adjusted P < 0.05; |log2FC| ≥ 1), with the vast majority upregulated in mastitic samples. Predicted cis- and trans-associated target analyses identified 637 non-redundant genes, and KEGG analysis identified 8 significantly enriched cis-associated pathways and 152 significantly enriched trans-associated pathways (adjusted P < 0.05), predominantly enriched for immune and inflammation-related pathways. These findings prioritized a subset of mastitis-associated lncRNAs for subsequent methylation and interaction-network analyses. A subset of these lncRNAs further overlapped differentially methylated regions (DMRs), suggesting a potential association between lncRNA expression changes and DNA methylation alterations. Integration of lncRNA–miRNA and miRNA–mRNA interactions identified lncRNA–miRNA–mRNA interaction networks involving DMR-associated lncRNAs. Among the prioritized candidates, MSTRG.28878.1 showed overlap with a hypomethylated promoter-associated DMR, increased expression, and multiple connections within the predicted interaction network. Together, these findings identify candidate lncRNAs, methylation-associated loci, and predicted molecular interactions associated with bovine subclinical mastitis and provide a resource for future functional investigation of candidate non-coding RNA-associated mechanisms in disease.
The Malabari goat of South India is one of the most efficient dual-purpose breeds, exhibiting exceptional adaptability to humid tropical stressors. This study aimed to characterize the complete mitochondrial genome of Malabari goats and to decipher their maternal phylogenetic relationships, thereby providing insights into lineage divergence, domestication origins and genetic connectivity with global caprine populations. Whole-genome sequencing of pooled DNA from 20 unrelated Malabari goats revealed a complete mitogenome comprising 37 genes, including 22 transfer RNAs (tRNAs), 13 protein-coding genes (PCGs) and two ribosomal RNAs (rRNAs), in addition to a hypervariable non-coding displacement loop (D-loop) region. A total of 45 single nucleotide polymorphisms (SNPs) and two indels were identified, of which 21 SNPs were detected in PCGs—six of them non-synonymous. Importantly, we report the first tRNA mutation described in goats: a novel heteroplasmic substitution (11693 T>C) in the MT-TL2 gene coding for tRNALeuCUN. The mitochondrial genome analysis of Malabari goats revealed their closest genetic affinity with Iraqi Meriz goats and Arabian goat populations, highlighting significant maternal contributions via ancient maritime trade networks, distinct from most Indian breeds that predominantly belong to haplogroup A. The whole mitogenome phylogenetic analysis revealed that Malabari goats cluster in a monophyletic group together with local goats from Vietnam, domestic goats from Malaysia and domestic goats from Russia. Phylogenetic reconstruction based on mitochondrial D-loop placed Malabari goats within haplogroup B1 along with goats from Iraq, Oman and Gujarat in India. Mitogenome analysis of Malabari goats provides genetic evidence of their genetic roots shaped by maritime exchanges along the ancient Spice Route.
Osteosarcoma is a highly aggressive bone malignancy with a strong tendency for metastasis and poor clinical outcomes. The molecular mechanisms driving osteosarcoma progression and metastasis remain incompletely understood, highlighting the need to identify robust biomarkers and therapeutic targets. Weighted gene co-expression network analysis (WGCNA) was performed using osteosarcoma datasets from the Gene Expression Omnibus to identify metastasis-associated gene modules and hub genes. Expression, methylation, mutation, immune infiltration, and drug sensitivity analyses were conducted using multiple public databases, including TCGA, GSCA, UALCAN, and cBioPortal. A prognostic model was developed using the TARGET osteosarcoma cohort and validated in an independent GEO dataset. Functional roles of hub genes were investigated through loss- and gain-of-function experiments in sarcoma cell lines using RT-qPCR, Western blotting, proliferation, colony formation, wound-healing, and luciferase reporter assays. Four hub genes, AURKB, CDC20, KIF11, and TOP2A, were identified as strongly associated with metastasis. These genes were significantly upregulated in sarcoma tissues and cell lines and demonstrated excellent diagnostic performance. Promoter hypomethylation and frequent genomic alterations contributed to their aberrant expression. High expression of the hub genes was associated with poor overall survival, and a four-gene prognostic model showed strong predictive performance in both training and validation cohorts. Functional assays confirmed that these genes promote sarcoma cell proliferation and migration, while miRNA-mediated regulation and drug resistance associations further highlighted their biological relevance. This integrated computational and experimental study identifies AURKB, CDC20, KIF11, and TOP2A as key oncogenic drivers in osteosarcoma, with significant diagnostic, prognostic, and therapeutic implications.
The Snell’s waltzer mouse (Myo6sv/sv) serves as a model for human deafness and vestibular behavioral impairment, caused by a spontaneous 130 bp recessive deletion in the Myo6 gene. In this study, we characterized the auditory and vestibular phenotypes of Myo6sv/sv mice. These mice exhibit profound hearing loss, with cochlear hair cell stereocilia beginning to fuse soon after birth, ultimately leading to disorganization of hair bundles and degeneration of hair cells. Mice also exhibit behavioral phenotypes characterized by severe imbalance, hyperactivity with bouts of circling, and delayed spatial learning of a novel environment, but preserved normal behavioral circadian rhythms. These behaviors emerge in association with the loss of the characteristic staircase morphology of vestibular hair cell stereocilia soon after birth and the subsequent profound elongation of the stereocilia. Adeno-associated virus (AAV) gene replacement therapy, delivered on the day of birth or one day after, failed to restore auditory or vestibular function. Our findings underscore the essential role of Myo6 in the auditory and vestibular systems and imply prenatal intervention may be required for effective therapy.
Copy number variations (CNVs) represent an important source of structural genomic variation contributing to genomic diversity in livestock species. The Nagami Mithun (Bos frontalis), a semi-domesticated bovid indigenous to the forested hill regions of Northeast India, remains poorly characterized at the level of genome structural variation. In this study, whole-genome resequencing data from 12 Nagami Mithun individuals were analyzed to establish the first genome-wide copy number variation (CNV) map for this indigenous population. After quality filtering and alignment to the Bos taurus ARS-UCD2.0 reference genome, CNVs were detected using the read-depth-based tool CNVnator v0.4.1 with stringent filtering criteria (e-value < 0.05, q0 < 0.5, length > 1 kb). A total of 7273 CNVs were identified, including 5005 deletions (68.8
Meniere’s disease (MD) is a heterogeneous, rare inner ear disorder characterized by recurrent vertigo, fluctuating sensorineural hearing loss, tinnitus, and aural fullness. Its molecular mechanisms remain unclear due to significant clinical and immunological heterogeneity. In this study, we integrated multi‑omics genetic data to systematically screen for palmitoylation regulatory genes associated with MD risk. We first intersected 31 core palmitoylation genes with blood cis‑eQTL datasets to identify candidate expression‑related genes, then performed two‑sample Mendelian randomization (MR) to examine their genetic correlation with MD. Summary‑data‑based MR (SMR) using two independent peripheral blood eQTL cohorts (eQTLGen and GTEx) was further applied to validate robust candidate genes. Two‑sample inverse‑variance weighted (IVW) MR revealed nominally significant associations between PPT2, ZDHHC18, ZDHHC5 and MD risk. Independent SMR validation confirmed that peripheral ZDHHC5 expression was significantly correlated with MD (eQTLGen: PSMR = 0.023; GTEx: PSMR = 0.006), and a non‑significant HEIDI test ruled out strong linkage disequilibrium confounding. We further explored potential immune mediators using a two‑step MR screening framework covering 731 peripheral immune cell phenotypes. After Benjamini–Hochberg false discovery rate (FDR) correction for all immune traits to control for multiple testing, no immune cell phenotype retained an FDR < 0.05 association with MD; therefore, formal mediation analysis was not conducted. In summary, this MR‑based genetic analysis identifies ZDHHC5 as a gene associated with MD susceptibility. The potential immune regulatory axis involving NKT cells remains speculative and requires validation through large‑scale stratified immune cohort data and functional cellular/animal experiments. No definitive causal or therapeutic conclusions can be drawn from the present genetic statistical evidence alone.
Systemic lupus erythematosus (SLE) is a chronic life-threatening and relapsing-remitting multisystem autoimmune disease. However, the genetic susceptibility of SLE has not been fully elucidated. This study will explore the genetic risk loci of SLE. We performed the larger multi-ancestry meta-analysis of genome-wide association study (GWAS) including 22,494 cases with SLE and 1,568,102 healthy controls. Multi-ancestry meta-analysis identified 101 risk loci including 12 novel loci. Across 101 loci, 2,209 likely causal genes are indicated and 265 genes are prioritized, based on eight biological prioritization criteria. The most significantly locus were located on 6p21.32, whereas the highest-ranked candidate causal gene was BLK. Heritability analyses demonstrated a liability scale of the heritability is 25.49
Calcification often occurs as a characteristic pathological manifestation in the progression of atherosclerosis (AS) plaques, but its mechanism is not fully understood yet. The purpose of this research was to supplement the exploration of key candidate genes and key cells involved in the calcification process of AS, building on existing insights into its underlying mechanisms. Through the examination of our internally generated single‑cell RNA sequencing (scRNA-seq) dataset derived from human carotid plaque samples, pivotal cellular populations associated with AS calcification were successfully identified. Following this identification, a comprehensive analytical approach was employed, incorporating differential gene expression profiling alongside the establishment of protein-protein interaction (PPI) networks, thereby enabling the extraction of critical genetic markers within these cellular subsets. Furthermore, a molecular regulatory framework was assembled, aiming to elucidate the mechanistic pathways through which these genetic determinants contribute to the calcification phenomena in AS pathology. Moreover, analysis of cell communication was applied to explore the interactions among cells. Pseudo-time analysis was employed to explore the expression of key candidate genes during the differentiation of key cells. Finally, monocytes were identified as key cells. WARS1, IFITM1, ANXA1, ADGRE2, and S100P were identified as key candidate genes. Moreover, 115 transcription factors such as THRB and 118 miRNAs such as hsa-miR-196a-5p were predicted to be associated with the key candidate genes. Across both calcified and non-calcified control specimens, the cellular communication between endothelial cells and natural killer (NK) T cell populations was consistently orchestrated via the PPBP-CXCR2 signaling axis. During monocytic differentiation trajectories, ADGRE2 expression exhibited a biphasic pattern characterized by initial gradual elevation followed by subsequent decline. Conversely, both ANXA1 and S100P demonstrated progressive upregulation throughout the differentiation process. The expression of IFITM1 and WARS1 first decreased, then increased, and finally decreased again. The present investigation successfully pinpointed five critical genes alongside one key cellular population, collectively providing potential molecular insights and candidate targets for further investigation into AS calcification.
The flare-horned markhor (Capra falconeri), a near-threatened mountain ungulate endemic to the Western Himalayas, remains vulnerable to habitat fragmentation, human disturbance, and environmental change. Although localized conservation efforts have stabilized some populations, genomic resources for this species remain limited. Here, we report nuclear and mitochondrial genome assemblies for C. falconeri, including a nuclear genome assembly (GCA_038502695.1) and a complete mitochondrial genome (OR799853.1), and place these data within an ecological context derived from field surveys. A structured winter survey conducted between 2020 and 2022 documented 225 individuals across 14 sites, indicating a demographically stable population with marked spatial heterogeneity. Genome-completeness assessment with BUSCO indicated that the short-read nuclear assembly is a fragmented draft (49.4
The International Mouse Phenotyping Consortium (IMPC) has established a large-scale functional genomics resource by systematically generating and phenotyping knockout mouse lines, linking gene function to mammalian phenotypes. However, interpreting disease-associated non-coding variants remains particularly challenging due to their abundance, context-dependent activity, and the complexity of gene regulation. Genome-wide association studies (GWAS) have shown that many disease-associated loci map to non-coding regions. In addition, recent large-scale consortia have catalogued millions of candidate cis-regulatory elements (CREs) across mammalian genomes; however, predicting which elements contribute to disease-relevant gene regulation and organismal phenotypes remains difficult. Together, these observations highlight disease-relevant CREs as an important but still underexplored component of human disease mechanisms. In this white paper, we outline strategies to address this challenge: (i) prioritization of disease-relevant candidate CREs, (ii) genome editing in mice to functionally evaluate CREs, and (iii) the establishment of interdisciplinary working groups. By extending its activities beyond protein-coding sequences, the IMPC has a unique opportunity to define the functional and phenotypic impact of disease-relevant CREs in vivo at scale, thereby improving our understanding of how non-coding regulatory elements contribute to mammalian phenotypes and human disease.
The SNF2-family Helicase-Like Transcription Factor (HLTF) has been implicated in tumorigenesis, with evidence suggesting both tumour-suppressive and oncogenic functions. To clarify the nature of this increasingly emerging double function, we analysed the full HLTF’s alterome across TCGA cohorts combining first gene expression with genomic and epigenomic layers of de-regulation, and investigating further their determinants through the integration of DNA methylation profiles - both at promoter-proximal and distal regions, the copy-number alterations, and all somatic mutations. This multi-layered analysis highlighted specific context-dependent HLTF’s regulatory configurations across human cancers, even modulated by either dosage effects or loss-of-function events. The clinical relevance of HLTF’s alterations, identified through tumour-specific associations with patient outcomes, supports its potential as new biomarker in cancer overall.
Triple-negative breast cancer (TNBC), characterized by the absence of ER, PR, and HER2 expression, is associated with aggressive clinical behavior and limited treatment options. Hypoxia in the tumor microenvironment (TME) may influence intercellular communication through exosomes. In this study, we investigated whether hypoxia-derived exosomes regulate malignant phenotypes of TNBC cells through exosomal miRNAs. Exosomes derived from hypoxic TNBC cells increased proliferation, migration, and invasion of recipient TNBC cells compared with normoxia-derived exosomes. Small RNA sequencing and RT-qPCR validation showed enrichment of miR-4791 in hypoxia-derived exosomes. Functional assays indicated that miR-4791 overexpression promoted TNBC cell proliferation, whereas miR-4791 inhibition reduced proliferative capacity. Mechanistically, miR-4791 directly targeted the 3′UTR of CTCFL and was associated with reduced PTEN expression. Rescue experiments suggested that restoration of CTCFL or PTEN partially attenuated miR-4791-associated malignant phenotypes in vitro and in vivo. Analysis of GSE19536 showed higher miR-4791 expression in breast cancer tissues than in normal tissues; however, the number of normal samples was limited. Survival analysis using GSE19783 indicated that higher miR-4791 expression was associated with poorer survival, although the prognostic ROC performance was weak-to-modest. Overall, these findings suggest that hypoxia-derived exosomal miR-4791 may contribute to TNBC progression, at least in part, through a CTCFL/PTEN-related mechanism.
Glaucoma is a complex neurodegenerative disease with multiple subtypes, yet all are characterized by the progressive dysfunction and loss of retinal ganglion cells (RGCs), which ultimately results in vision impairment and blindness. Elevated intraocular pressure (IOP) is a major risk factor for glaucoma; however, it is neither necessary nor sufficient for glaucomatous neurodegeneration, as patients can exhibit high IOP without developing glaucoma and patients can develop glaucoma with normal IOP. Yet FDA-approved treatment options are largely limited to approaches to minimize risk and reduce IOP. Thus, there is a critical need to target other aspects of glaucoma pathophysiology. Neuroinflammation is broadly defined here as immune-relevant responses, often involving microglia and astrocytes, within the central nervous system which may include peripheral immune cell infiltration. Burgeoning evidence has implicated glia in the development and progression of glaucoma in human tissues and mouse models. Most mouse models of glaucoma to date have shown that microglia and astrocytes are reactive in early stages of glaucomatous neurodegeneration prior to overt RGC loss. However, there is growing evidence that human and mouse glia adopt distinct phenotypes in response to neurodegeneration. Thus, there is critical need to expand our studies to include the new generations of human cell culture models. In this review, we discuss: 1) the evidence of neuroinflammatory processes in human glaucoma; 2) models of glaucoma relevant neuroinflammation; and the evidence specifically for 3) innate immune cell-driven and 4) macroglia-driven processes.
Diabetic nephropathy (DN) is a leading cause of chronic kidney disease. Salvianolic acid A (SAA) has shown promising therapeutic potential against DN, yet its underlying mechanisms and precise molecular targets remain incompletely elucidated. Potential targets of SAA were predicted using SwissTargetPrediction and SuperPred, with its drug-like properties evaluated by ADMET analysis. Diabetic nephropathy (DN)-related targets were collected from GEO, CTD, and GeneCards databases. Shared targets underwent GO and KEGG enrichment analyses. Core targets were identified through topological analysis in Cytoscape, machine learning, and Mendelian randomization validation. Molecular docking and dynamics simulations assessed the binding affinity and stability between SAA and core targets. Single-cell RNA sequencing data revealed their cell type-specific expression in kidney tissues. Experimental validation was performed using an in vitro high glucose-induced podocyte injury model analyzed by RT-qPCR. The intersection of 212 drug targets with 5,097 disease targets yielded 134 potential therapeutic targets for salvianolic acid A in DN. Machine learning and Mendelian randomization further identified eight targets with causal relationships to DN. Molecular docking demonstrated strong binding affinities of salvianolic acid A to the domains of FYN, AKR1B1, TNF, GALK1, HMGCR, MAP2K2, SCN4A, and ITGA5. Single-cell analysis revealed distinct expression patterns across different renal cell types. In vitro experiments demonstrated that SAA effectively protected podocytes from HG-induced injury. SAA alleviates diabetic nephropathy through multi-target mechanisms, influencing key genes involved in disease progression. This study provides a systematic elucidation of the therapeutic basis for SAA and supports its further clinical development.
Yak (Bos grunniens) is a high-altitude adapted bovine species native to the Himalayan and Tibetan plateau, thriving at elevations above 3000 m from msl under hypobaric hypoxia. Despite its remarkable physiological adaptations, a complete transcriptomic understanding across multiple organs remains limited. In this study, full-length transcriptome sequencing of 22 tissues was performed using PacBio Iso-Seq, generating over 200,000 high-quality non-redundant RNA transcripts. This dataset significantly improves yak genome annotation and reveals widespread isoform diversity, including thousands of novel transcripts and 4,319 high-confidence lncRNAs. Enrichment of key hypoxia-related pathways such as HIF-1, PI3K-Akt, AMPK, and TGF-β was observed, along with tissue-specific expression patterns in vascular, immune, and reproductive systems. These results provide a valuable multi-organ transcriptomic resource and offer new insights into the genetic mechanisms supporting high-altitude adaptation in yak.
Here we highlight the utilities of optical genome mapping (OGM) in determining the genomic rearrangements present in a novel transgenic mouse line (Line 781), which expresses the bacterial lacZ reporter gene under control of the mouse myelin proteolipid protein (Plp1) promoter. Hemizygous transgenic mice from Line 781 present with a mutant phenotype (documented here) which entails small body size and paws and craniofacial aberrations that are 100% penetrant, whereas their non-transgenic littermates are phenotypically normal. OGM was used to determine that the transgene sits at the intersection of an unbalanced reciprocal translocation between chromosomes 1 and 2, with deletion of approximately 3.9 (chr1) and 1.8 (chr2) Mbp from the rearranged (derivative) chromosomes, thus resulting in a monosomy over these regions in the mutant genome. As well, OGM was able to determine the number of full-length copies of transgene that integrated and their orientation. Sanger sequencing of PCR products that span a junction were used to determine the chromosomal breakpoints and transgene integration site, precisely. The complex chromosomal rearrangements in Line 781 span 38 protein-coding genes that result in the transection of 1 gene from chr1 and deletion of 33 and 4 genes from chr1 and chr2, respectively. The resulting mutant phenotype is consistent with 1q24 deletion syndrome in humans having an interstitial deletion of the syntenic region in Chr1. Thus, our mouse mutant may serve as an animal model, in future studies, to explore the molecular and cellular basis of anomalies present in patients with 1q24 deletion syndrome.
