CircB3GNTL1 and miR-598 regulation effects on proliferation, apoptosis, and glutaminolysis in gastric cancer cells.

This study was performed to research circB3GNTL1 control, miR-598 and its mechanism for cell proliferation, apoptosis and glutamine breakdown. For this purpose, CirB3GNTL1 and miR-598 expressions were detected by qRT-PCR in gastric and cell lines; MTT tests were performed to detect proliferation; flow cytometry was established in flow; glutamine decomposition was evaluated with glutamine, glutamic acid and α-keto-glutaric acid (α-KG) expression; Bcl-2, PCNA, ASCT2 and GLS1 expression levels were calculated; Methods of expression were calculated. The results showed that CircB3GNTL1 expression was up-regulated and miR-598 expression was up-regulated in gastric cancer tissues and cell lines; Knockdown circB3GNTL1 prevented proliferation and glutamine decomposition of the gastric cancer cells and induced apoptosis compared with normal para-cancers and gastric cancer cell lines. Results circB3GNTL1 can target and control miR-598 expression, and miR-598 can reverse the proliferation, apoptosis, and decomposition of glutamine from gastric cancer cells by knockdown circB3GNTL1. It was concluded that CirB3GNTL1 prevents decomposition of glutamines and induces apoptosis by controlling miR-598 in gastric cancer cells. PMID: 33287917 [PubMed - in process]

This study focused on S-1 adherence by evaluating real-world adherence to S-1 and investigating factors related to decreased S-1 adherence. This study included cases treated between August 1, 2014 and October 12, 2016 at the Cancer Institute Hospital of the Japanese Foundation for Cancer Research. The S-1 adherence rate per cycle was defined as the number of times a patient took S-1/28. In this study, adherence to S-1 was assessed through pill counts and by asking the patient about the reason for non-adherence at a pharmaceutical outpatient clinic. Univariate and multivariate analyses were performed to investigate factors ...

CONCLUSION: GC patients are often accompanied by changes in TMB, and its expression level is closely related to the degree of pathological differentiation, which is an independent factor affecting the prognosis of GC patients. High TMB value can evaluate the prognosis and provide a reference for the formulation of clinical treatment plans for GC patients.PMID:34335754 | PMC:PMC8321718 | DOI:10.1155/2021/3374939

CONCLUSION: miR-193a prominently decreased the proliferation, invasion, and activation of the PI3K/Akt signaling pathway and the abilities of epithelial-to-mesenchymal transition in gastric cancer cells. The newly identified miR-193a/PSEN1 axis provides novel insight into the pathogenesis of gastric cancer.PMID:34335753 | PMC:PMC8298175 | DOI:10.1155/2021/2804478
