Crosstalk between gut microbiota and tumor: tumors could cause gut dysbiosis and metabolic imbalance.

Gut microbiota has a proven link with the development and treatment of cancer. However, the causality between gut microbiota and cancer development is still unknown and deserves exploration. In this study, we aimed to explore the alterations in gut microbiota in murine tumor models and the crosstalk between the tumor and the gut microbiota.

Mendelian randomization study on simvastatin and gastric cancer: exploring the therapeutic potential of statins in oncology.

Background: Gastric cancer ranks as the fifth most prevalent cancer and the third leading cause of cancer-related mortality worldwide, Statins, renowned for their cholesterol-lowering effects, have garnered interest for their potential roles in cancer prevention and treatment due to their pleiotropic effects, such as anti-proliferative, pro-apoptotic, and anti-inflammatory properties. This study aims to investigate the therapeutic potential of simvastatin, a widely prescribed statin, in the context of gastric cancer using Mendelian randomization (MR) to explore a possible causal relationship between simvastatin use and gastric cancer risk.

Methods: We conducted a two-sample MR analysis utilizing summary statistics from genome-wide association studies (GWAS).

Early Postnatal Exposure to Midazolam Causes Lasting Histological and Neurobehavioral Deficits via Activation of the mTOR Pathway.

Exposure to general anesthetics can adversely affect brain development, but there is little study of sedative agents used in intensive care that act via similar pharmacologic mechanisms. Using quantitative immunohistochemistry and neurobehavioral testing and an established protocol for murine sedation, we tested the hypothesis that lengthy, repetitive exposure to midazolam, a commonly used sedative in pediatric intensive care, interferes with neuronal development and subsequent cognitive function via actions on the mechanistic target of rapamycin (mTOR) pathway. We found that mice in the midazolam sedation group exhibited a chronic, significant increase in the expression of mTOR activity pathway markers in comparison to controls.

Natural compound Alternol actives multiple endoplasmic reticulum stress-responding pathways contributing to cell death.

Alternol is a small molecular compound isolated from the fermentation of a mutant fungus obtained from Taxus brevifolia bark. Our previous studies showed that Alternol treatment induced reactive oxygen species (ROS)-dependent immunogenic cell death. This study conducted a comprehensive investigation to explore the mechanisms involved in Alternol-induced immunogenic cell death.

PKM2 promotes glioma progression by mediating CTNNB1 expression.

Background: Glioma is a common intracranial tumor, exhibiting a high degree of aggressiveness and invasiveness. Pyruvate kinase M2 (PKM2) is overexpressed in glioma tissues. However, the biological role of PKM2 in glioma is unclear.

Causal Associations Between Gut Microbiota, Gut Microbiota-Derived Metabolites, and Alzheimer's Disease: A Multivariable Mendelian Randomization Study.

Background: Multiple studies have demonstrated that the gut microbiome is closely related to the onset of Alzheimer's disease, but the causal relationship between the gut microbiome and AD, as well as potential mediating factors, have not been fully explored.

Objective: Our aim is to validate the causal relationship between the gut microbiome and the onset of AD and determine the key mechanism by which the gut microbiome mediates AD through blood metabolites using Mendelian randomization (MR) analysis methods.

Methods: We first conducted bidirectional and mediating MR analyses using gut microbiota, blood amino acid metabolites, and AD-related single nucleotide polymorphisms as research data.

Amino acid transporter SLC7A5 regulates cell proliferation and secretary cell differentiation and distribution in the mouse intestine.

The intestine is critical for not only processing nutrients but also protecting the organism from the environment. These functions are mainly carried out by the epithelium, which is constantly being self-renewed. Many genes and pathways can influence intestinal epithelial cell proliferation.

Sirt1 alleviates osteoarthritis via promoting FoxO1 nucleo-cytoplasm shuttling to facilitate autophagy.

This study aims to investigate the role and underlying mechanisms of Sirt1 in the pathophysiological process of OA. Safranine O and HE staining were utilized to identify pathological changes in the cartilage tissue. Immunohistochemistry was employed to evaluate the expression levels of proteins.

Region-specific transcriptomic responses to obesity and diabetes in macaque hypothalamus.

The hypothalamus plays a crucial role in the progression of obesity and diabetes; however, its structural complexity and cellular heterogeneity impede targeted treatments. Here, we profiled the single-cell and spatial transcriptome of the hypothalamus in obese and sporadic type 2 diabetic macaques, revealing primate-specific distributions of clusters and genes as well as spatial region, cell-type-, and gene-feature-specific changes. The infundibular (INF) and paraventricular nuclei (PVN) are most susceptible to metabolic disruption, with the PVN being more sensitive to diabetes.

Exogenous hydrogen sulfide ameliorates diabetes-associated cognitive dysfunction by regulating the nrf-2/HO-1 axis and the NLRP3 inflammasome pathway in diabetic rats.

Diabetes-associated cognitive dysfunction (DACD) is a complication of diabetes mellitus that leads to an increased risk of cognitive impairment and dementia. However, the molecular mechanism underlying DACD has not been elucidated, and a promising therapy for this disease remains to be established. Hydrogen sulfide (HS), a significant antioxidative and anti-inflammatory gasotransmitter, has emerged as a neuroprotective agent.

Long non-coding RNA growth arrest-specific 5 inhibits liver fibrogenesis in biliary atresia by interacting with microRNA-222 and repressing IGF1/AKT signaling.

Background: Long non-coding RNA growth arrest-specific 5 (lncRNA GAS5) has been shown to inhibit liver fibrosis through serving as a competing endogenous RNA for microRNA-222 (miR-222). Progressive liver fibrosis is a typical characteristic of biliary atresia (BA). However, the role of GAS5/miR-222 and its underlying mechanisms remain largely unknown in BA.
