However, the underlying mechanisms of PV + interneuron dysfunction remain largely unclear. Here, we found that a deficiency of biorientation defective 1 ( Bod1) in PV + interneuron led to an ASD-like phenotype in Pvalb-Cre; Bod1 f/f mice. Mechanistically, we identified that Bod1 deficiency induced hypoactivity of PV + interneuron and hyperactivity of calcium/calmodulin-dependent protein kinase Ⅱ alpha (CaMKⅡα) neurons in the medial prefrontal cortex (mPFC), as determined by whole-cell patch-clamp recording. Additionally, it concurrently decreased the power of high gamma oscillation, as assessed by in vivo multi-channel electrophysiological recording. Furthermore, we found that Bod1 deficiency enhanced inwardly rectifying K + current, leading to an increase in the resting membrane potential of PV + interneurons. Importantly, the gain-of-function of Bod1 improved social deficits and stereotypical behaviors in Pvalb-Cre; Bod1 f/f mice. These findings provide mechanistic insights into the PV + interneuron dysfunction and suggest new strategies for developing PV + interneuron therapies for ASD.","PeriodicalId":15061,"journal":{"name":"Journal of Biomedical Research","volume":" ","pages":"1-13"},"PeriodicalIF":2.2,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143752769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under hypoxic conditions, oxygen deficiency disrupts oxidative phosphorylation in mitochondria, impairing ATP production and generating reactive oxygen species (ROS). These reactive species induce mitochondrial dysfunction, leading to oxidative stress, calcium imbalance, and activation of apoptosis pathways. Mitochondrial K-ATP (mitoK-ATP) and mitochondrial permeability transition pore (mPTP) channels are particularly affected, contributing to membrane potential loss, cytochrome C release, and cell death. This review explores the molecular mechanisms underlying hypoxia-induced cardiovascular diseases, with a focus on mitochondrial impairment, ion channel dysfunction, and ROS overproduction. Additionally, we examine hypoxia-inducible factor 1-alpha (HIF-1α) as a biomarker of cellular adaptation and discuss therapeutic strategies targeting mitochondrial function and oxidative stress. Antioxidants and compounds modulating key ion channels, such as K-ATP and mPTP, are highlighted as promising interventions for mitigating hypoxia-induced damage. Furthermore, we emphasize the potential of integrating in vitro, in vivo, and in silico studies to develop novel therapies aimed at preserving mitochondrial integrity and preventing cardiovascular diseases.","PeriodicalId":15061,"journal":{"name":"Journal of Biomedical Research","volume":" ","pages":"1-16"},"PeriodicalIF":2.2,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143692233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research on thyroid-related traits in lung carcinogenesis is limited. Using UK Biobank data, we conducted bidirectional Mendelian randomization (MR) to assess causal links between lung cancer risk and thyroid dysfunction (hypothyroidism/hyperthyroidism) or function traits (free thyroxine [FT4], normal-range TSH). Furthermore, in the smoking-behavior stratified MR analysis, we evaluated the mediating effect of thyroid-related phenotypes on the association between smoking phenotype and lung cancer. We confirmed significant associations between lung cancer risk and hypothyroidism (hazards ratio [HR] = 1.14, 95% confidence interval [CI] = 1.03-1.26, P = 0.009) as well as hyperthyroidism (HR = 1.55, 95% CI = 1.29-1.87, P = 1.90×10 -6) in the UKB. Moreover, the MR analysis indicated a causal effect of thyroid dysfunction on lung cancer risk (OR inverse variance weighted [IVW] = 1.09, 95% CI = 1.05-1.13, P = 3.12×10 -6 for hypothyroidism; OR IVW = 1.08, 95% CI = 1.04-1.12, P = 8.14×10 -5 for hyperthyroidism). We found that FT4 levels were protective against lung cancer risk (OR IVW = 0.93, 95% CI = 0.87-0.99, P = 0.030). Additionally, the stratified MR analysis demonstrated the distinct causal effect of thyroid dysfunction on lung cancer risk among smokers. Hyperthyroidism mediated the effect of smoking behavior, especially the age of smoking initiation (17.66% mediated), on lung cancer risk. Thus, thyroid dysfunction phenotypes play causal roles in lung cancer development exclusively among smokers and act as mediators in the causal pathway from smoking to lung cancer.","PeriodicalId":15061,"journal":{"name":"Journal of Biomedical Research","volume":" ","pages":"1-11"},"PeriodicalIF":2.2,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143596977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Activation of SIRT6 prevents cholestasis-associated pathological events, such as oxidative stress and mitochondrial biogenesis disorders, and inhibits bile acid synthesis to alleviate cholestatic liver injury. However, it is still uncertain which pathway is responsible for the therapeutic effect of SIRT6 in reducing cholestasis. Therefore, we treated liver-specific Sirt6 knockout mice with N-Acetylcysteine, Keap1-Nrf2-IN-1, or acadesine to remove oxidative stress and/or trigger mitochondrial biogenesis after cholestatic liver disease modeling, but these measures did not significantly improve cholestatic symptoms. However, MDL801, a SIRT6 agonist that downregulating CYP7A1, the key enzyme in bile acid synthesis, exhibited favorable therapeutic effects. In addition, the hepatic knockdown of Cyp7A1 further confirmed that inhibition of hepatic bile acid synthesis might be the main pathway by which SIRT6 alleviates cholestatic liver disease. These findings provide a solid basis for the potential application of SIRT6 agonists in the treatment of cholestatic liver disease.","PeriodicalId":15061,"journal":{"name":"Journal of Biomedical Research","volume":" ","pages":"1-17"},"PeriodicalIF":2.2,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142769215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
