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}

In a clinical case, anlotinib reversed osimertinib resistance in Non-small cell lung cancer (NSCLC). We performed an immunohistochemical experiment on tumor tissues from three non-small cell lung cancer patients exhibiting osimertinib resistance to analyze alterations in the expression levels of EMT markers and vascular endothelial growth factor A (VEGFA) before and after osimertinib resistance. The results revealed the downregulation of E-cadherin, coupled with the upregulation of vimentin and VEGFA in tumor tissues of patients exhibiting osimertinib resistance, compared with the expression in tissues of patients before taking osimertinib. Subsequently, we established osimertinib-resistant cell lines and found that the osimertinib-resistant cells acquired the EMT features. Then, we analyzed the synergistic effects of the combination therapy to verify whether anlotinib could reverse osimertinib resistance by inhibiting EMT. The expression levels of VEGFA and micro-vessels were analyzed in the combination group in vitro. Finally, we explored the reversal of osimertinib resistance in combination with anlotinib in vivo with 20 nude mice. The combined treatment of osimertinib and anlotinib effectively prevented the metastasis of resistant cells, which also inhibited tumor growth, exerted anti-tumor activity, and ultimately reversed osimertinib resistance in mice. The co-administration of osimertinib and anlotinib demonstrated their synergistic efficacy in inhibiting EMT and angiogenesis in three NSCLC patients, ultimately reversing osimertinib resistance.","PeriodicalId":15061,"journal":{"name":"Journal of Biomedical Research","volume":" ","pages":"1-15"},"PeriodicalIF":2.2,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142390788","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}

Helminths play potent roles in the host through generating a variety of novel molecules, including some excretory/secretory products and others that are involved in intracellular material exchange and information transfer as well as the initiation or stimulation of immune and metabolic activation. The helminth-derived molecules have developed powerful and diverse immunosuppressive effects to achieve immune evasion for parasite survival and establish chronic infections. However, they also improve autoimmune and allergic inflammatory responses and promote metabolic homeostasis by promoting metabolic reprogramming of various immune functions, and then inducing alternatively activated macrophages, T helper 2 cells, and regulatory T cells-mediated immune responses. Therefore, a deeper exploration of the immunopathogenic mechanism and immune regulatory mechanisms of helminth-derived molecules exerted in the host is crucial for understanding host-helminth interactions as well as the development of therapeutic drugs for infectious or non-infectious diseases.

Despite its crucial role during the surgery, the precise effect of anesthesia on cancer patient outcomes is not clearly understood. This comprehensive review aims to elucidate the various anesthesia strategies used in the perioperative care of cancer patients and their potential effects on patients' prognosis, but understanding the complex relationship between anesthesia and cancer outcomes is crucial, given the complexity in cancer treaments. Examining potential implications of anesthesia strategies on cancer patient prognosis may help better understand treatment efficacy and risk factors of cancer recurrence and metastasis.

The objective of the current study was to ascertain molecular evolution of intestinal-type gastric cancer according to the Correa cascade for the precise gastric cancer screening. We collected sequential lesions of the Correa cascade in the formalin-fixed and paraffin-embedded endoscopic submucosal dissection-resected specimens from 14 Chinese patients by microdissection, and subsequently determined the profiles of somatic aberrations during gastric carcinogenesis using the whole exome sequencing, identifying multiple variants at different Correa stages. The results showed that TP53, PCLO, and PRKDC were the most frequently mutated genes in the early gastric cancer (EGC). A high frequency of TP53 alterations was found in low-grade intraepithelial neoplasia (LGIN), which further increased in high-grade intraepithelial neoplasia (HGIN) and EGC. Intestinal metaplasia (IM) had no significant correlation with EGC in terms of mutational spectra, whereas both LGIN and HGIN showed higher genomic similarities to EGC, compared with IM. Based on Jaccard similarity coefficients, three evolutionary models were further constructed, and most patients showed linear progression from LGIN to HGIN, ultimately resulting in EGC. The ECM-receptor interaction pathway was revealed to be involved in the linear evolution. Additionally, the retrospective validation study of 39 patients diagnosed with LGIN indicated that PRKDC mutations, in addition to TP53 mutations, may drive LGIN progression to HGIN or EGC. In conclusion, the current study unveils the genomic evolution across the Correa cascade of intestinal-type gastric cancer, elucidates the underlying molecular mechanisms of gastric carcinogenesis, and provides some evidence for potential personalized gastric cancer surveillance.","PeriodicalId":15061,"journal":{"name":"Journal of Biomedical Research","volume":" ","pages":"1-16"},"PeriodicalIF":2.2,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142307812","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}
