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 <i>in vitro</i>. Finally, we explored the reversal of osimertinib resistance in combination with anlotinib <i>in vivo</i> 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.

Despite its crucial role during the surgery, the precise effect of anesthesia on cancer patient outcomes is not clearly understood.

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 <i>TP53</i>, <i>PCLO</i>, and <i>PRKDC</i> were the most frequently mutated genes in the early gastric cancer (EGC). A high frequency of <i>TP53</i> 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 <i>PRKDC</i> mutations, in addition to <i>TP53</i> 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.</p>","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}

Krüppel-like factors (KLFs) are important transcription factors in eukaryotes. Studies have reported that KLF4 and KLF5 are correlated with several cardiovascular diseases, but population-based studies on associations between HT and KLF4 or KLF5 have rarely been reported. Therefore, the current study investigated the associations of genetic variants and mRNA expression levels of <i>KLF4</i> and <i>KLF5</i> with HT, as well as the effects of antihypertensive drugs on the expression levels of these genes. The associations of one single-nucleotide polymorphism (SNP) in <i>KLF4</i> and three SNPs in <i>KLF5</i> with HT were analyzed using a combination of case-control and cohort studies. The study populations were selected from a community-based cohort in four regions of Jiangsu province. The risks of HT were estimated through logistic and Cox regression analyses. In addition, mRNA expression levels of <i>KLF4</i> and <i>KLF5</i> were detected in 246 controls and 385 HT cases selected from the aforementioned cohort. Among the HT cases, 263 were not taking antihypertensive drugs [AHD(-)] and 122 were taking antihypertensive drugs [AHD(+)]. In the case-control study, SNP rs9573096 (C>T) in <i>KLF5</i> was significantly associated with an increased risk of HT in the additive model (adjusted odds ratio [OR], 1.106; 95% confidence interval [CI], 1.009 to 1.212).
