Randall's plaque (RP) is recognized as a precursor lesion for kidney stones, with its formation and progression potentially linked to oxidative stress. Previous studies have provided limited insights into the underlying mechanisms of RP, failing to fully elucidate its molecular pathways. To investigate the relationship between oxidative stress and RP, we employed bioinformatics approaches to identify key genes, predict associated pathways and drug molecules, analyze variations in immune cell populations, and construct diagnostic models.

Cancer-associated fibroblasts (CAFs) exert multiple tumor-promoting functions and are key contributors to drug resistance. The mechanisms by which specific subsets of CAFs facilitate oxaliplatin resistance in colorectal cancer (CRC) have not been fully explored. This study found that THBS2 is positively associated with CAF activation, epithelial-mesenchymal transition (EMT), and chemoresistance at the pan-cancer level.

The recent advancements in cancer immunotherapy have spotlighted the potential of natural killer (NK) cells, particularly chimeric antigen receptor (CAR)-transduced NK cells. These cells, pivotal in innate immunity, offer a rapid and potent response against cancer cells and pathogens without the need for prior sensitization or recognition of peptide antigens. Although NK cell genetic modification is evolving, the viral transduction method continues to be inefficient and fraught with risks, often resulting in cytotoxic outcomes and the possibility of insertional mutagenesis.

Background: Mitochondrial transcription elongation factor (TEFM) is a recently discovered factor involved in mitochondrial DNA replication and transcription. Previous studies have reported that abnormal TEFM expression can disrupt the assembly of mitochondrial respiratory chain and thus mitochondrial function. However, the role of TEFM on Uterine corpus endometrial carcinoma (UCEC) progression remains unclear.

For patients undergoing long-term peritoneal dialysis (PD), exposure to biologically incompatible PD solutions and the consequent peritoneal structure change can lead to progressive angiogenesis and fibrosis, and ultimately result in ultrafiltration failure (UFF). Peritoneal transport studies in aquaporin 1 (AQP1) knockout mice indicate that water transport across the peritoneum is mediated by AQP1, which accounts for up to 50% of ultrafiltration. Another recent study on a large cohort of PD patients with kidney failure further substantiated the impact of AQP1 genotype variation on water channel expression in the peritoneal membrane, influencing water transport, ultrafiltration, and patient prognosis.

The polycomb protein complex interacts with GATA-6/PPARα to inhibit α-MHC expression.

Dev Growth Differ

December 2024

Department of Biochemistry & Molecular Biology, School of Basic Medical Sciences, Zhengzhou University, Zhengzhou, China.

Transcription factors collaborate with epigenetic regulatory factors to orchestrate cardiac differentiation for heart development, but the underlying mechanism is not fully understood. Here, we report that GATA-6 induces cardiac differentiation but peroxisome proliferator-activated receptor α (PPARα) reverses GATA-6-induced cardiac differentiation, possibly because GATA-6/PPARα recruits the polycomb protein complex containing EZH2/Ring1b/BMI1 to the promoter of the cardiac-specific α-myosin heavy chain (α-MHC) gene and suppresses α-MHC expression, which ultimately inhibits cardiac differentiation. Furthermore, Ring1b ubiquitylates PPARα and GATA-6.
