Hypoxia plays a critical role in both physiological and pathological processes. Cells adapt to hypoxia through the extensive reprogramming of gene expression. While the transcriptional regulations of hypoxia-inducible factors (HIFs) are well-studied, recent advances have emphasized the importance of post-transcriptional regulation, including mRNA translation, modification, stability, and degradation. Summarizing the regulation of mRNA homeostasis under hypoxia will improve our understanding of how hypoxia contributes to diseases such as cancer and ischemic injury. This review systematically summarizes the regulation of mRNA metabolism by hypoxia across multiple levels. First, hypoxia remodels mRNA transcription initiation and elongation. HIF-1 plays a critical role in this process by recruiting RNA polymerase II and releasing promoter-proximal pausing. Second, hypoxia suppresses global protein synthesis by phosphorylating eIF2α and inhibiting mTOR, while selectively upregulating key mRNAs (e.g., VEGFA) via internal ribosome entry sites (IRES). Third, hypoxia influences mRNA modifications, including m6A, m5C, and ac4C, thereby modulating mRNA stability and translation. Lastly, hypoxia influences mRNA stability and degradation through poly(A) tail dynamics and AU-rich elements. Hypoxia orchestrates mRNA metabolism through interconnected transcriptional and post-transcriptional mechanisms, enabling cells to adapt to oxygen deprivation. RNA-binding proteins play a role throughout the entire lifespan of mRNA and could serve as potential therapeutic targets for the treatment of hypoxia-related diseases. Oxygen is essential for normal life activities in a wide range of organisms, especially mammals. An adequate supply of oxygen is necessary for cellular and tissue metabolism. Certain physiological or pathological conditions, such as high altitudes, cancer, or ischemic disease, result in low oxygen levels and pressure within cells. This phenomenon is called hypoxia. The central aim of the hypoxia response is to restore oxygen homeostasis. Previous studies have shown that cells primarily adapt to hypoxia through hypoxia-inducible factor-mediated transcriptional regulation. Recent studies indicate that hypoxia regulates the mRNA life cycle through processes such as synthesis, processing, translation, and degradation. This review illustrates how mRNA homeostasis is regulated under hypoxic conditions and provides potential therapeutic targets for hypoxia-related diseases.
Introduction Sishen Wan (SSW), a classical traditional Chinese medicine decoction, is described to treat ulcerative colitis (UC) patients, but the molecular mechanisms of the main active ingredients of SSW on the interaction between mitochondria and T cells are still unclear. This study aimed to determine the main active ingredients of SSW, predict and explore the possible regulatory mechanism of main active ingredients of SSW in modulating mitochondrial function and ameliorating mitochondrial damage, followed by regulating T cell balance during UC development. Methods Colorimetric test and quantitative real-time polymerase chain reaction (qRT-PCR) were performed to evaluate the efficacy of SSW on inflammatory injuries of UC and preliminarily explore the mechanisms of SSW against oxidative stress. The main active components and their possible ligands were predicted by network pharmacology, molecular docking, dynamic simulation and three-dimensional-quantitative structure activity relationship (3D-QSAR). RNA-seq analysis and western blot (WB) was conduct to discover the impact of SSW on genetic profile changes, and discover and predict the potentials of anti-mitochondrial damage and proinflammatory T-cells of the selected bioactive compounds. Results SSW effectively ameliorated the colonic injuries and alleviated the oxidative stress in the dextran sulphate sodium (DSS)-induced UC. Angelicin, corylifolinin, psoralen and rutaecarpine, derived from SSW, were identified as the main components of SSW, and might interact with CYP2C9 and CYP1A1 due to the lowest binding energy. SSW alleviated UC via regulating genes related to mitochondrial function and T cell responses based on RNA-seq data. Cytc-related targets and T cell-associated proinflammatory cytokines were downregulated, while mtDNA repairing-related targets were upregulated with SSW intervention. Moreover, the caspase, inflammasome and Th1 and Th17 polarizing-related genes are positively correlated with cytochrome C oxidase (COX), caspase and inflammasome-associated genes, respectively. Conclusion Taken together, this study not only identifies the main bioactive ingredients of SSW and their possible ligands, but also provides angelicin, corylifolinin, psoralen and rutaecarpine may alleviate oxidative stress and mitochondrial damage, followed by modulating Th1 and Th17-related proinflammatory cytokines.
Alzheimer's disease (AD) incidence is rising with no effective treatments. Eleutheroside B (EB) has neuroprotective potential, but its therapeutic effects and mechanisms in AD are unclear. This study investigated EB's effects on AD pathologies and elucidated its underlying mechanisms using a transgenic Caenorhabditis elegans (C. elegans) model. We found that EB could ameliorate cognitive impairment, locomotor dysfunction, and shortened lifespan induced by amyloid-β(Aβ) and Tau aggregation in C. elegans, and reduce the relative expression levels of Aβ, Tau, and phosphorylated Tau (p-Tau) proteins. EB improved the health status and anti-aging capacity of the worms, as evidenced by prolonged healthspan, elevated pharyngeal pumping rate and body bend frequency, and increased body length and width. Notably, EB exhibited no observable toxicity even at high-dose administration. Furthermore, EB activated key stress-responsive transcription factors skn-1, daf-16, and hsf-1; it also increased the expression levels of antioxidant enzymes superoxide dismutase-3(SOD-3) and glutathione S-transferase 4(GST-4), decreased reactive oxygen species (ROS) levels, and elevated the expression of heat shock proteins Hsp-4 and Hsp-6. EB also reduced the accumulation of p62/SQST-1 protein, promoted the colocalization of lgg-1:GFP with lysosomes, and increased the relative mRNA expression of autophagy-related genes aak-2, unc-51, bec-1, vps-34, and lgg-1. After targeted knockdown of these genes, the protective effects of EB against AD-related pathologies were abolished. Our findings demonstrate that EB exhibits anti-aging properties and potential for ameliorating AD, which is likely mediated via antioxidative activities and autophagy induction.
Ulcerative colitis (UC) is a nonspecific inflammatory disease. Baicalein has potential value in treating UC, but its mechanism is unclear. This study aims to evaluate the protective effects of baicalein on dextran sodium sulfate (DSS)-induced UC mice. The UC model was established by 4% DSS solution for 7 days. Treatments included baicalein (10 mg/kg, 20 mg/kg) and sulfasalazine (200 mg/kg) via oral gavage. Colonic damage was assessed through body weight, disease activity index (DAI), histopathology (H&E staining) and colon length. Inflammatory cytokines were measured by ELISA, while oxidative stress markers and iron content were analyzed by colorimetric assays. Protein expression was evaluated by Western blot, and gene levels by RT-qPCR. Intestinal microbiota changes were characterized using 16S rRNA gene sequencing. Results demonstrated that Baicalein ameliorated UC mice, particularly in high-dose of baicalein group. After baicalein treatment, the proinflammatory cytokines (TNF-α, IL-1β), and anti-inflammatory cytokine (IL-10) has decreased. Additionally, high-dose of baicalein strongly reversed oxidative stress alterations caused by DSS, as evidenced by Fe2+, MDA, ROS significantly depleted, and MPO, SOD, GSH significantly increased. Protein and mRNA expression analyses revealed that high-dose baicalein upregulated the expression of FTH1, GPX4, SLC7A11, SLC3A2 and Nrf2, while downregulating ACSL4 significantly. Microbiological analysis showed that baicalein ameliorated intestinal dysbiosis, increased Ligilactobacillus and NK4A136, while reduced Clostridium_sensu_stricto_1 and Escherichia-Shigella. These findings suggest that baicalein mitigates DSS-induced UC mice by reducing oxidative stress and inflammation, suppressing ferroptosis and modulating gut microbiota composition, Proposing a potentially effective therapeutic approach for UC.
Fluoride, a naturally occurring element found in water, soil, food, and atmospheric precipitation, can lead to fluorosis and various health issues when consumed excessively. However, the mechanism of fluorosis is still under investigation. This study utilizes Caenorhabditis elegans as a model organism to investigate the effects of fluoride exposure on biological systems and to explore the mechanisms by which curcumin mitigates fluoride-induced toxicity. Three groups were established: a blank control, a sodium fluoride (NaF) exposure group (concentration 5 mmol/L), and a curcumin intervention group (concentration 25 μmol/L). Physiological parameters, lipofuscin levels, intracellular reactive oxygen species (ROS) levels, mitochondrial membrane potential, and mitochondrial copy numbers were measured to assess the effects of fluoride toxicity and curcumin protection. RNA-seq and qRT-PCR were utilized to investigate the molecular mechanisms underlying fluoride-induced damage and curcumin's mitigating effects. Results indicated that fluoride-exposed nematodes displayed physiological abnormalities, increased ROS production, higher lipofuscin levels, altered mitochondrial membrane potential and mitochondrial copy number, and activated MAPK signaling pathway genes. Curcumin exhibited protective effects on these parameters, suggesting its potential in preventing fluoride-induced harm by modulating oxidative stress and preserving mitochondrial function. This research enhances our understanding of the mechanisms of fluoride toxicity and highlights the potential benefits of curcumin.
Alternative splicing (AS) is a universal phenomenon in eukaryotes, and it is still challenging to identify AS events. Several methods have been developed to identify AS events, such as expressed sequence tags (EST), microarrays and RNA-seq. However, EST has limitations in identifying low-abundance genes, while microarray and RNA-seq are high-throughput technologies, and PCR-based technology is needed for validation. To overcome the limitations of EST and shortcomings of high-throughput technologies, we established a method to identify AS events, especially for low-abundance genes, by reverse transcription (RT) PCR with gene-specific primers (GSPs) followed by nested PCR. This process includes two major steps: 1) the use of GSPs to amplify as long as the specific gene segment and 2) multiple rounds of nested PCR to screen the AS and confirm the unknown splicing variants. With this method, we successfully identified three new splicing variants, namely, GenBank Accession No. HM623886 for the bdnf gene (GenBank GeneID: 12064), GenBank Accession No. JF417977 for the trkc gene (GenBank GeneID: 18213) and GenBank Accession No. HM623888 for the glb-18 gene (GenBank GeneID: 172485). In addition to its reliability and simplicity, the method is also cost-effective and labor-intensive. In conclusion, we developed an RT-nested PCR method using gene-specific primers to efficiently identify known and novel AS variants. This approach overcomes the limitations of existing methods for detecting rare transcripts. By enabling the discovery of new isoforms, especially for low-abundance genes, this technique can aid research into aberrant splicing in disease. Future studies can apply this method to uncover AS variants involved in cancer, neurodegeneration, and other splicing-related disorders.
Non-coding genomic variants constitute the majority of trait-associated genome variations; however, the identification of functional non-coding variants is still a challenge in human genetics, and a method for systematically assessing the impact of regulatory variants on gene expression and linking these regulatory variants to potential target genes is still lacking. Here, we introduce a deep neural network (DNN)-based computational framework, RegVar, which can accurately predict the tissue-specific impact of non-coding regulatory variants on target genes. We show that by robustly learning the genomic characteristics of massive variant-gene expression associations in a variety of human tissues, RegVar vastly surpasses all current non-coding variant prioritization methods in predicting regulatory variants under different circumstances. The unique features of RegVar make it an excellent framework for assessing the regulatory impact of any variant on its putative target genes in a variety of tissues.

Curcumin is well known as a potent antioxidant and free radical scavenger and has great potential for anti-aging applications. In this study, we investigate the molecular mechanism of curcumin in prolonging the lifespan of C. elegans. Four concentrations of curcumin (10, 25, 50, and 100 µM) were administered, and the optimal treatment concentration was determined by analyzing the nematode lifespan, physiology, and biochemistry. Additionally, RNA-seq and qRT-PCR were performed to explore the antioxidant effect of curcumin and its underlying mechanism. Results revealed that curcumin could significantly improve the survival capacity of C. elegans without influencing its growth. Curcumin was observed to significantly decrease the levels of reactive oxygen species (ROS) under extreme conditions such as heat stress and paraquat stress. In addition, curcumin increased the amount of nematode mitochondrial DNA (mtDNA) replication. RNA-seq results revealed that the underlying mechanism of curcumin in C. elegans is related to the mitogen-activated protein kinase (MAPK) pathway. qRT-PCR results confirmed that the expression of oxidative stress-related genes (sod-1, sod-2, sod-3, gst-4) was increased, and the expression of MAPK signaling pathway-related genes (sek-1, pmk-1, nsy-1) was significantly downregulated. Furthermore, the administration of curcumin extended the lifespan of nematodes, potentially through the enhancement of oxidative stress resistance and the downregulation of the MAPK signaling pathway. These findings improve our understanding of both lifespan extension and the potential mechanism of curcumin in C. elegans.

Alzheimer's disease (AD) is the most common form of dementia without effective clinical treatment. Here, we show that intermittent fasting (IF) improves cognitive functions and AD-like pathology in a transgenic AD mouse model (5XFAD). IF alters gut microbial composition with a significant enrichment in probiotics such as Lactobacillus. The changes in the composition of the gut microbiota affect metabolic activities and metabolite production. Metabolomic profiling analysis of cecal contents revealed IF leads to a decreased carbohydrate metabolism (for example, glucose) and an increased abundance in amino acids (for example, sarcosine and dimethylglycine). Interestingly, we found that the administration of IF-elevated sarcosine or dimethylglycine mimics the protective effects of IF in 5XFAD mice, including the amelioration of cognitive decline, amyloid-β (Aβ) burden and glial overactivation. Our findings thus demonstrate an IF regimen is a potential approach to prevent AD progression, at least through the gut-microbiota-metabolites-brain axis, and constitutes an innovative AD therapeutic avenue.
Purpose Propofol is commonly used as an intravenous anesthetic in surgical patients. However, its usage is associated with adverse effects. Auxiliary medication can reduce the dose of intravenous anesthetics. Hence, we investigated whether vitamin C could lower propofol dosage in elderly patients undergoing total knee replacement surgery. Patients and Methods The trial was carried out in PLA General Hospital in Beijing, China. We enrolled patients aged ≥50 years who were undergoing unilateral total knee arthroplasty with total intravenous anesthesia combined with lumbar sciatic nerve block. The patients were randomly assigned to either the vitamin C (Vc) group (0.067 g/kg) or the control group (an equivalent dose of normal saline). Nerve block was done for all the patients before the general anesthesia. The same depth of anesthesia was maintained during the operation. We compared the propofol dosage and adverse events (eg hypotension) during anesthesia between the two groups. This study was registered with the Chinese Clinical Trial Registry, www.chictr.org.cn, number ChiCTR-TRC-16010112. Results There were significant differences in the total infusion dose (Vc group: 704.3 ± 188.6 mg; control group: 888.6 ± 232.7 mg; p = 0.016) and the average maintenance dose of propofol (Vc group: 5.8 ± 1.0 mg/kg/h; control group: 6.9 ± 1.6 mg/kg/h; p = 0.013). But there were no significant differences in the induction dose of propofol (control group: 90 mg, range 80–115 mg; Vc group: 100 mg, range 90–110 mg, p = 0.379) between the Vc and control groups. Furthermore, there were no significant differences in the hemodynamics and the incidence of intraoperative hypotension. Conclusion Vitamin C can reduce the dosage of propofol in patients undergoing total knee replacement.
ALT The Intake of Extremely Low Minerals and Bacteria Consumable Saccharides Secured Safety and Persistent of 7-14 Days Prolonged Total Dietary Deprivation Regimen. In: Abstract Objectives: The aim of this study was to evaluate a total fasting regimen assisted by a novel prebiotic, Flexible Abrosia (FA), in more than 7 days of continual dietary deprivation (7D-CDD). Our analysis included basic physical examinations, bioelectrical impedance analysis, and clinical lab and ELISA analysis in normal volunteers. Methods : Eight healthy subjects with normal body weight participated in 7D-CDD with the assistance of a specially designed probiotic. Individuals were assigned to take FA (113.4 KJ/10g/dose) at each mealtime to avoid possible injuries to intestinal flora and smooth the hunger sensation. During 7D-CDD, the subjects were advised to avoid any food intake, especially carbohydrates, except for drinking plentiful amounts of water. The examination samples were collected before CDD as self-control, at 7-d fasting, and after 7~14 d of refeeding. Four subjects were also tested after 6-m refeeding. Results: The FA-CDD regimen significantly decreased suffering from starvation, with tolerable hunger sensations during the treatment. With the addition of daily mineral electrolytes, the subjects not only passed through the entire 7D-CDD regimen but also succeed in up to 14D total fasting in three subjects. There was a significant reduction in blood glucose, insulin, and high-density lipoprotein levels during fasting, and the blood concentrations of uric acid (UA), alanine aminotransferase (ALT), and creatine kinase (CK) were increased. However, after more than 2 months of refeeding, the disease markers ALT, GOT, and CK either remained stable or were slightly downregulated compared to their initial 0 D control level. Conclusion: Our experiment has supplied the first positive evidence that, with the assistance of a daily nutritional supply around 100 kcal total calories to their intestinal flora, human subjects were able to tolerate hunger sensations. We have found that, although 7D-CDD induced increases in UA, CK, and transferases during fasting, refeeding led the markers to become either down-regulated or unchanged compared to their initial levels. This phenomenon was further confirmed in longer-term (6 m) recovery. Our results failed to support the hypothesis that fasting induced liver damage, since ALT, GOT, and CK remained low after longer-term refeeding. Our findings indicate that our 7D-CDD regimen which target of Intestinal flora saturation might be practical and that it might be valuable to design larger clinical fasting trials for improvement of health strategy-targeting in metabolic disorders.
