Lipopolysaccharide and lipoteichoic acid regulate the PI3K/AKT pathway through osteopontin/integrin β3 to promote malignant progression of non-small cell lung cancer
CONCLUSIONS: This study provides a theoretical basis for further exploration of the influence of lung microbiota on NSCLC and the optimization of LC treatment in the future.PMID:36794132 | PMC:PMC9922606 | DOI:10.21037/jtd-22-1825

Inhibition of ATF4-mediated elevation of both autophagy and AKT/mTOR was involved in antitumorigenic activity of curcumin
In this study, however, autophagy and mTOR were found to be inhibited simultaneously by curcumin treatments, and both of them played an important role in the effect of curcumin on suppressing the growth of A549 cells. Tunicamycin (TM), the activator of Endoplasmic Reticulum (ER) stress, increased both autophagy and AKT/mTOR, while curcumin could significantly decrease TM-induced autophagy and AKT/mTOR. Furthermore, curcumin could inhibit TM-induced aerobic glycolysis in A549 cells, and decrease the level of cycle-related and migration-related proteins. Blocking activating transcription factor 4 (ATF4) by siRNA strongly red...

GSE178987 An RNAi therapeutic targeting hepatic DGAT2 in a genetically obese mouse model of nonalcoholic steatohepatitis
Contributors : Batuhan Yenilmez ; Lawrence Lifshitz ; Michael Czech ; Anastasia KhvorovaSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusNonalcoholic steatohepatitis (NASH) is a severe liver disorder characterized by triglyceride accumulation, severe inflammation, and fibrosis. With the recent increase in prevalence, NASH is now the leading cause of liver transplantation, with no approved therapeutics available. Despite years of research, the exact molecular mechanism of NASH progression is not well understood, but fat accumulation is believed to be the primary driver of the disease. T...

Petits ARN interf érents : applications potentielles pour les néphrologues Small interfering RNA: potential applications for nephrologists
Nephrol Ther. 2022 Dec;18(6S1):6S1-6S6. doi: 10.1016/S1769-7255(22)00646-0.ABSTRACTSmall interfering RNA (siRNAs) are double-stranded RNAs of around 20 base pairs in length that trigger RNAi machinery, which promotes degradation of a target mRNA avoiding protein translation. SiRNAs are liver-targeted, using tris N-acetylgalactosamine (GalNAc) as the targeting ligand. This discovery received the Nobel Prize for medicine and physiology in 2006 and lead to substantial therapeutic advances. Application field and development of these siRNA has been very fast. Indeed, patisiran has been released in 2018 for hereditary transthyre...
