Astragaloside IV inhibits pathological functions of gastric cancer-associated fibroblasts through regulation of the HOXA6/ZBTB12 axis
This study aimed to investigate the potential mechanism of astragaloside IV in the regulation of CAF pathological functions in gastric cancer development. Homeobox A6 (HOXA6), and Zinc Finger and BTB Domain Containing 12 (ZBTB12) are highly expressed in gastric CAFs compared with normal fibroblasts (NFs) based on the GSE62740 dataset. We found that astragaloside IV-stimulated CAFs suppressed cell growth, migration, and invasiveness of gastric cancer cells. HOXA6 and ZBTB12 were downregulated after astragaloside IV treatment in CAFs. Further analysis revealed that HOXA6 or ZBTB12 knockdown in CAFs also exerted inhibitory ef...

Risk factors for metachronous esophageal squamous cell carcinoma after endoscopic or surgical resection of esophageal carcinoma: a systematic review and meta-analysis
Conclusiontimely investigating the age of patients, previous history of cancer and monitoring the number of LVLs in the first 5 years after operation are of great significance to identify high-risk populations of MESCC for timely medical care. Education and behavior correction about smoking are advocated. Tumor markers should be regularly detected in the head and neck, esophagus, and stomach. Endoscopic resection was associated with a higher incidence of MESCC, which provided a reference for doctors to choose the removal method.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier CRD42022377030.

Anticancer effect of umbelliferone on MKN-45 and MIA PaCa-2 cell lines
In this study, the anticancer activity of umbelliferone (7-hydroxycoumarin-UMB) was investigated in MKN-45 human gastric cancer and MIA PaCa-2 human pancreatic cancer cells. The cytotoxic effect of UMB on MKN-45 and MIA PaCa-2 cells was determined by WST-8 cell viability assay; the effect on colony formation and migration potential by colony forming assay and wound healing/cell migration assay. Apoptotic effect of UMB was determined by measuring the change in mitochondrial membrane potentials, reactive oxygen species levels, and Caspase-3 activities in cells. Anticancer drugs cisplatin and gemcitabine were used as positive...

Immune responses of six-transmembrane epithelial antigen of the prostate 4 functions as a novel biomarker in gastric cancer
CONCLUSION: The current findings suggest an oncogenic role for STEAP4 in GC, with significantly high levels being associated with poor prognosis. Investigation of the GC tumor microenvironment suggests the potential function of STEAP4 is connected with the infiltration of diverse immune cells, which may contribute to the regulation of the tumor microenvironment. In conclusion, STEAP4 may serve as a potential therapeutic target for GC to improve the immune infiltration, as well as serve as a prognostic biomarker for judging the prognosis and immune infiltration status of GC.PMID:37700807 | PMC:PMC10494559 | DOI:10.5306/wjco.v14.i8.297

Correlation of microsatellite status and EBV infection with clinical characteristics of patients with gastric cancer
This study was designed to investigate the correlation of microsatellite status (MS) and Epstein-Barr virus (EBV) infection with the clinical characteristics of gastric cancer (GC) patients. MS was detected by immunohistochemistry. EBV was detected by in situ hybridization. There were 31.3% cases showed mismatch repair-deficient (dMMR)/ microsatellite instability (MSI) and 68.7% cases showed mismatch repair-proficient (pMMR)/ microsatellite stability (MSS). The dMMR/MSI was more common in the elderly, in patients with cardia GC, smaller tumor diameter or non-poorly differentiated carcinoma. The survival in dMMR/MSI patient...

Prognostic significance and immune characteristics of GPR27 in gastric cancer
Aging (Albany NY). 2023 Sep 12;15. doi: 10.18632/aging.205023. Online ahead of print.ABSTRACTGastric cancer (GC) is one of the most typical cancerous neoplasms occurring in the digestive system. For advanced GC, immunotherapy is the final option for them to prolong survival time. Hence, we aimed to identify new molecular targets to enhance the immunotherapy response in GC individuals. Then we applied bioinformatic analysis to explore the expression profiles of G-protein-coupled receptor 27 (GPR27) transcription and GPR27 methylation. The associations between survival of GC patients and GPR27 transcription and methylation w...

NRP1 regulates autophagy and proliferation of gastric cancer through Wnt/ β-catenin signaling pathway
Aging (Albany NY). 2023 Mar 7;15. doi: 10.18632/aging.204560. Online ahead of print.ABSTRACTGastric cancer possesses high lethality rate, and its complex molecular mechanisms of pathogenesis lead to irrational treatment outcomes. Autophagy plays a dual role in cancer by both promoting and suppressing the cancer. However, the role of autophagy in gastric cancer is still vague. Therefore, in this study, we first obtained autophagy-related genes from the Human Autophagy Database, and then applied consensus clustering analysis to analyse the molecular subtypes of gastric cancer samples in the TCGA database. The genes obtained ...
