Infantile hemangioma (HEM) is the most common benign vascular tumor in infancy and is characterized by a unique progression pattern involving rapid proliferation followed by spontaneous involution. Increasing evidence suggests that the tumor microenvironment plays a critical role in regulating endothelial cell behavior during HEM development. In this study, we investigated how fibroblast (FB) phenotypic remodeling influences hemangioma endothelial cell (HemEC) function. Through single-cell RNA sequencing analysis, we identified extensive communication between FBs and ECs within HEM tissues. Functional experiments revealed that adipogenically differentiated FBs markedly suppressed HemEC proliferation, migration, invasion, and tube formation while promoting apoptosis. Transcriptomic analysis further demonstrated that this inhibitory effect was mediated by activation of the Hippo-YAP/TAZ signaling pathway in ECs. Mechanistically, adipogenic differentiation significantly upregulated PPARG expression in FBs, which in turn triggered Hippo pathway activation in ECs, leading to YAP/TAZ phosphorylation and nuclear exclusion. Importantly, PPARG silencing in FBs or pharmacological inhibition of the Hippo pathway reversed these effects. Collectively, our findings reveal a previously unrecognized microenvironmental regulatory mechanism in which PPARγ-driven fibroblast adipogenesis suppresses HEM progression through activation of the Hippo-YAP/TAZ pathway in endothelial cells. This study provides new insights into stromal-endothelial communication in HEM and suggests that the PPARγ-Hippo signaling axis may represent a potential therapeutic target. Proposed molecular mechanism by which PPARγ-mediated FB adipogenic differentiation regulates Hippo-YAP/TAZ signaling activity in HemECs. Note: Created in Biorender.
Aims: In this study, we aimed to decipher the impact of enhancer of zeste homolog 2 (EZH2) in psoriasis as well as the underlying mechanism. Methods: A mouse model of psoriasis was developed by means of imiquimod induction, with the expression of EZH2, microRNA-125a-5p (miR-125a-5p), and SFMBT1 determined. The role of EZH2, miR-125a-5p, and SFMBT1 in malignant phenotypes of HaCaT cells and the development of psoriasis in vivo was subsequently investigated through gain- and loss-of-function experiments. Chromatin immunoprecipitation assay and dual-luciferase reporter assay were conducted to explore the relationship between EZH2 or SFMBT1 and miR-125a-5p. Finally, the effects of EZH2 and miR-125a-5p on the transforming growth factor β (TGFβ)/SMAD pathway were analyzed. Results: Overexpressed SFMBT1 and EZH2 was detected while miR-125a-5p were downregulated in psoriasis tissues and human keratinocyte (HaCaT) cells. EZH2 increased the levels of IL-17A-induced cytokines and promoted the malignant phenotypes of HaCaT cells. Functionally, EZH2 reduced miR-125a-5p expression while miR-125a-5p targeted SFMBT1 to activate the TGFβ/SMAD pathway in vitro . Knockdown of EZH2 or up-regulation of miR-125a-5p inhibited cell proliferation and the levels of IL-17A-induced cytokines, but increased the expression of TGFβ1 and the extent of smad2 and smad3 phosphorylation in HaCaT cells. Notably, EZH2 contributed to the development of psoriasis in vivo by inhibiting the TGFβ/SMAD pathway via impairment of miR-125a-5p-mediated SFMBT1 inhibition. Conclusion: Taken together, the results of the current study highlight the ability of EZH2 to potentially inactivate the TGFβ/SMAD pathway via upregulation of miR-125a-5p-dependent SFMBT1during the progression of psoriatic lesions.
Chronic idiopathic urticaria (CIU) is an unfavorable skin condition which could be maintained for six weeks or longer time. Gremlin1 (GREM1) was recently applied in treatments of many diseases. However, the possible regulatory mechanism of GREM1 in CIU remained unclear. This study aimed to explore the regulatory effects of GREM1 on the inflammatory response and vascular permeability mediated by mast cells of CIU via TGF-β signaling pathway. Initially, microarray analysis was used to identify CIU-related differentially expressed genes and the potential mechanism of this gene. A mouse model of CIU was established. To explore the functional role of GREM1 in CIU, the modeled mice were then injected with GREM1-siRNA, SRI-011381 (the activator of TGF-β signaling pathway), or both, followed by serum test, and immunoglobulin detection. The levels of inflammatory factors and tryptase, β-hexosaminase, histamine in the serum were detected. Besides, vascular endothelial cell permeability and the target relation between GREM1 and TGF-β were also examined. Mice injected with SRI-011381 exhibited higher levels of tryptase, β-hexosaminase, histamine, inflammation-related factors and increased vascular endothelial cell permeability, while GREM1-silenced mice yet expressed opposite tendency. Silencing of GREM1 was demonstrated to inhibit the TGF-β signaling pathway. Taken together, our results demonstrated that down-regulation of GREM1 could potentially impede inflammatory response and vascular permeability by suppressing TGF-β signaling pathway. GREM1 may promote the development of prognosis management and therapeutic treatment in CIU.

Congenital muscular torticollis (CMT) is typically characterized by lateral flexion of the head to one side and cervical rotation to the opposite side due to unilateral shortening of the sternocleidomastoid muscle. Infants with CMT under the age of 1 year old are frequently treated with physical therapy, such as manual stretching and mass massage, and are evaluated by visual or angular measurement. However, there are no consensus on the techniques to perform the physical therapy examination and intervention. The International Classification of Functioning, Disability and Health-Children and Youth Version (ICF-CY) is an international tool for recording and describing the functions, disability, and health status of children and adolescents, emphasizing that the condition of the disease or health is determined by the combination of body structure and function, activity, participation, and environmental factors, and the treatment of this disease requires overall analysis and integrated intervention. This article applies the ICF-CY framework to review the physical therapy examination and intervention of CMT. Key words: Congenital muscular torticollis; International Classification of Functioning, Disability and Health-Children and Youth Version; Physical therapy examination; Therapy
The aim of this study is to evaluate serum 25-hydroxyvitamin D[25(OH)D] levels in children with tic disorders and to explore the relationship between serum 25(OH)D level and tic severity. Children (n = 179, 31 females, 148 males, mean age at diagnosis: 8.0 ± 2.7 years old, age ranged from 3 to 14.5 years old) who were diagnosed with a tic disorder were enrolled as case group, 189 healthy children were recruited as control group. Serum level of 25(OH)D of each child was measured by high performance liquid chromatography and tandem mass spectrometry (HPLC-MS/MS). Yale Global Tic Severity Scale (YGTSS) was used to assess tic severity. Mean serum level of 25(OH)D in the case group was significantly lower than that of the control group. The serum 25(OH)D level was significantly associated with tic severity after adjusting for age and body mass index (BMI). This study identified a high prevalence of vitamin D insufficiency or deficiency in children with tic disorders, and there was a negative correlation between the serum 25(OH)D level and tic severity. In the future, large sample size studies are urgently needed to further clarify this correlation.
Tic disorders (TD) are a group of neurodevelopmental disorders that are characterized by motor and/or vocal tics in children and adolescents. The etiology and pathogenesis of TD remain unclear, and it is believed to be caused by a combination of genetic, biological, psychological, and environmental factors. The major treatment for TD includes psychoeducation, behavioral intervention, and drug treatment. To further explore the management of TD, this article reviews the research advances in psychoeducation and behavioral intervention for patients with TD.
Objective The amyloid β-protein precursor contains a domain highly homologous to Kunitz-type serine protease inhibitors. We have successfully established and characterized the recombinant human rhKD/APP in vitro. The aim of this study is to investigate the potential neuroprotective role of rhKD/APP on cerebral ischemia/reperfusion injury in rats. Methods Rats pretreated with rhKD/APP (4, 8, 16 mg/kg) were subjected to prepare models of cerebral ischemia/reperfusion (I/R) injury and those rats treated with Nimodipine were used as positive control. Comparison of the scores of neurological deficits, TTC-stained infarct volume and cerebral water content between the groups was performed. The activities of SOD, Na+-K+-ATPase and the content of MDA in the cortex tissues were measured and the activities of serum myeloperoxidase ( MPO) enzyme were also compared. The expressions of adhesion molecules ( ICAM-1 and E-selectin) were compared by immunohistochemistry. End-labeling of nuclear DNA fragmentation (TUNEL) and qualification of caspase-3, Bcl-2 and Bax were also employed to evaluate the local apoptosis in cortex tissues. Results By pretreatment with the rhKD/APP at three doses, cerebral infarct volume, water content and neurological deficits were all reduced. The activities of SOD, and Na+-K+-ATPase were increased, the contents of MDA were decreased in the cortex tissues, and the serum MPO activity was reduced. The expressions of adhesion molecules were downregulated and the apoptotic signaling of neurons were inhibited. All the changes induced by rhKD/APP treatment in the ischemia/reperfusion injury models showed statistical significance compared with the control rats. However, no significant difference was shown between the rhKD/APP group and Nimodipine group excepted for the reduced MPO in sera. Conclusions The result of this study suggest that rhKD/APP has neuroprotective effect on the cerebral ischemia/reperfusion injury through inhibiting multiple signaling pathways and is promising to be a potential neuroprotective drug.

The long non-coding RNAs (lncRNAs) regulating encoding transcripts/genes involved in Wnt signalling pathway in keloids is largely unclear. We used a pathway-focused lncRNA microarray to detect the differentiated expression profiles of both lncRNAs and genes involved in Wnt pathway, thus a total of 116 Wnt-targeted genes and 69 Wnt-related lncRNAs aberrantly expressed in keloids were initially identified. A stepwise bioinformatics was further performed to find skin-related lncRNA/gene pairs in Wnt pathway in keloids. Firstly, an lncRNA/gene co-expression network with clustered functional modules was constructed; simultaneously, 114 Wnt-genes regarding to dermis were online enriched using Phenotype Enrichment. Secondly, 17 skin-related keloid-aberrant Wnt-genes were acquired by overlapping the 114 skin-related Wnt-genes with the 116 keloid-aberrant Wnt-genes. Thirdly, after co-expression coefficient of each lncRNA/gene profile being ranked respectively, 11 top co-expressed lncRNAs characterized with the highest co-expression coefficients to the 17 genes were identified. Fourthly, seven of the 11 top co-expressed lncRNAs exhibiting array-detected aberrant expression in keloids, together with their 12 most interactive Wnt-genes, were selected to undergo in-pair intracellularly quantitative PCR validation in keloids. As a result, four lncRNAs including CACNA1G-AS1, HOXA11-AS, LINC00312 and RP11-91I11.1 with their six paired Wnt-genes undergoing both array-and-qPCR as well as lncRNA-and-gene double validation were finally identified as skin-related lncRNA/gene pairs that involved in Wnt signalling pathway in keloids. In conclusion, in-depth exploration on these easily-accessible lncRNAs in keloids might aid to find the novel target on how to maintain highly recurrent tumours benign via Wnt-involved network regulation.
