Hydrophobicity causes anomalous migration of cystine/glutamate antiporter SLC7A11 in SDS-PAGE with low acrylamide concentration.

The cystine/glutamate antiporter, solute carrier family 7 member 11 (SLC7A11), plays a crucial role in regulating redox homeostasis and cell death processes such as apoptosis and ferroptosis. These processes are implicated in various diseases, including cancer, organ injuries and neurodegenerative disorders. However, the sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) expression pattern of SLC7A11 varies across studies and remains unclear.

Inhibition of Endoplasmic Reticulum Stress Cooperates with SLC7A11 to Promote Disulfidptosis and Suppress Tumor Growth upon Glucose Limitation.

Disulfidptosis is a newly discovered type of regulated cell death triggered by disulfide bond accumulation and NADPH (nicotinamide adenine dinucleotide phosphate) depletion due to glucose deprivation. However, the regulatory mechanisms involving additional cellular circuits remain unclear. Excessive disulfide bond accumulation can impair endoplasmic reticulum (ER) homeostasis and activate the ER stress response.

Secreted protein TNA: a promising biomarker for understanding the adipose-bone axis and its impact on bone metabolism.

Background: Osteoporosis (OP) is a systemic bone disease characterized by reduced bone mass and deterioration of bone microstructure, leading to increased bone fragility.

Obesity is strongly associated with OP, and adipose tissue can influence platelet function by secreting adipokines.

Tumor suppressor BAP1 suppresses disulfidptosis through the regulation of SLC7A11 and NADPH levels.

BAP1, BRCA1-Associated Protein 1, serves as a novel tumor suppressor through the deubiquitination of monoubiquitination of H2A and subsequent gene transcriptional regulation. Regulated cell death like apoptosis or ferroptosis is considered an essential mechanism mediating tumor suppression. Previous reports, including ours, have demonstrated that BAP1 could promote apoptosis and ferroptosis to inhibit tumor development.

Machine Learning-based Development and Validation of a Cell Senescence Predictive and Prognostic Signature in Intrahepatic Cholangiocarcinoma.

Previous studies have shown that cellular senescence is strongly associated with tumorigenesis and the tumor microenvironment. Accordingly, we developed a novel prognostic signature for intrahepatic cholangiocarcinoma (ICCA) based on senescence-associated long non-coding RNAs (SR-lncRNAs) and identified a lncRNA-miRNA-mRNA axis involving in ICCA. Based on the 197 senescence-associated genes (SRGs) from Genacards and their expression in Fu-ICCA cohort, we identified 20 lncRNAs as senescence-associated lncRNAs (SR-lncRNAs) through co-expression and cox-regression analysis.
