The systemic lupus erythematosus (SLE) is an autoimmune disease, leading to inflammatory response and systemic consequences. The mammalian target of rapamycin (mTOR) is a therapeutic target for autoimmune diseases like SLE. The aim of this study was to evaluate the effects of the mTOR rs2295080 and rs2536 polymorphisms and AKT1 rs2494732 gene polymorphism on SLE development. 2 ml of peripheral blood was collected from 165 SLE patients and 170 controls in EDTA-containing tubes. The salting-out and PCR-RFLP methods were used for DNA extraction and genotype analysis, respectively. Based on the regression analysis, the frequency of TT genotype of mTOR rs2295080 polymorphism was significantly higher in the case group than that of the control group, with a 2.6-fold increased risk of SLE. There was also a significant difference between the two groups in terms of allelic distribution. No statistically significant association was found between The AKT1 rs2494732 and mTOR rs2536 polymorphisms and SLE development. Our results showed that the TT genotype and T allele of mTOR rs2295080 polymorphism were risk factors for developing SLE. However, there was no significant association between mTOR rs2536 and AKT1 rs2494732 polymorphisms and the SLE risk.

Stereocaulon alpinum has been found to have potential pharmaceutical properties due to the presence of secondary metabolites such as usnic acid, atranorin, and lobaric acid (LA) which have anticancer activity. On the other hand, the effect of LA on the stemness potential of colorectal cancer (CRC) cells remains unexplored, and has not yet been thoroughly investigated. In this study, we examined the inhibitory activity of LA from Stereocaulon alpinum against the stemness potential of CRC cells and investigated the possible underlying mechanisms.

The Warburg effect, a common feature of solid tumors, rewires the metabolism and promotes growth, survival, proliferation, and long-term maintenance in gastric cancer (GC). We performed in vitro and in vivo studies of the pathogenesis of GC to investigate the effects and mechanism of LINC01224 in this cancer. qRT-PCR was used to measure the expression of LINC01224 or miR-486-5p in GC cells, and the expression of LINC01224 in GC tissues by FISH (Fluorescence in situ hybridization) analysis was evaluated.

Apolipoprotein C1 (APOC1) plays a significant role in the proliferation and metastasis of various malignant tumors; however, its role in DLBCL-particularly its effects on angiogenesis-remains largely unexplored. This study investigates the correlation between APOC1 expression and patient prognosis in DLBCL.

Metabolic dysfunction-associated steatohepatitis (MASH) is one of the most common chronic liver diseases and is mainly caused by metabolic disorders and systemic inflammatory responses. Recent studies have indicated that the activation of the mammalian (or mechanistic) target of rapamycin (mTOR) signaling participates in MASH progression by facilitating lipogenesis and regulating the immune microenvironment. Although several molecular medicines have been demonstrated to inhibit the phosphorylation or activation of mTOR, their poor specificity and side effects limit their clinical application in MASH treatment.

Background: Epidemiological investigations have revealed a significant association between alcohol consumption and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Nevertheless, the potential mechanisms are still inadequately revealed. This research aimed to investigate the impact of alcohol on CP/CPPS using an animal model and to elucidate the underlying mechanisms.
