NSUN2-Mediated R-loop Stabilization as a Key Driver of Bladder Cancer Progression and Cisplatin Sensitivity.

R-loops are critical structures that play pivotal roles in regulating genomic stability and modulating gene expression. This study investigates the interactions between the 5-methylcytosine (mC) methyltransferase NOP2/Sun RNA methyltransferase 2 (NSUN2) and R-loops in the transcriptional dynamics and damage repair process of bladder cancer (BCa) cells. We observed markedly elevated levels of R-loops in BCa cells relative to normal urothelial cells.

Acetylation of E2F1 at K125 facilitates cell apoptosis under serum stress.

E2F1 is a critical transcription factor that regulates cell cycle progression, is expressed at high levels in most cancer cells, and activates the biogenesis of proteins related to the cell cycle. Over recent years, researchers have demonstrated that E2F1 could also facilitate cellular apoptosis under conditions of cellular stress, thus creating a double-edged sword associated with both the regulation of cellular survival and death. However, the mechanisms responsible for these actions remain poorly understood.

Chatbots for breast cancer education: a systematic review and meta-analysis.

Background: Effective education and awareness regarding breast cancer are critical. Traditional educational methods often fail to meet the diverse information needs of patients. Patients should be provided with tailored, accessible information to improve their retention and understanding of disease-related information.

Bulk and Single-Cell Transcriptome Analyses Unravel Gene Signatures of Mitochondria-Associated Programmed Cell Death in Diabetic Foot Ulcer.

Mitochondrial programmed cell death (PCD) plays a critical role in the pathogenesis of diabetic foot ulcers (DFU). In this study, we performed a comprehensive transcriptome analysis to identify potential hub genes and key cell types associated with PCD and mitochondria in DFU. Using intersection analysis of PCD- and mitochondria-related genes, we identified candidate hub genes through protein-protein interaction and random forest analysis.
