We report a case of successful design of glutathione S-transferase (GST) inhibitors via a natural product-inspired and electrophilicity-based strategy. Based on this strategy, a novel piperlongumine analog (PL-13) bearing a para-trifluoromethyl group and an α-chlorine on its aromatic and lactam rings, respectively, surfaced as a promising GST inhibitor, thereby overcoming cisplatin resistance in lung cancer A549 cells.

Background: Azathioprine (AZA) is part of the standard treatment for autoimmune hepatitis (AIH). The first step in the complex bioconversion of AZA to active metabolites is mediated by glutathione transferases (GSTs).

Aims: Elucidate the association between GSTM1 and GSTT1 copy number variation (CNV), genetic variation in GSTA2, GSTP1, and inosine-triphosphate-pyrophosphatase, and the response to AZA in AIH.

Oxytetracycline (OTC), a crop-absorbable antibiotic, poses a health risk to humans through the food chain. Conversely, 24-epibrassinolide (EBL), a plant growth hormone, mitigates the toxic effects of various pollutants on plants. However, the mechanism by which exogenous EBL affects the growth of rape seedlings exposed to OTC remains largely unknown.

HP1 Promotes the Centromeric Localization of ATRX and Protects Cohesion by Interfering Wapl Activity in Mitosis.

Background: α thalassemia/mental retardation syndrome X-linked (ATRX) serves as a part of the sucrose nonfermenting 2 (SNF2) chromatin-remodeling complex. In interphase, ATRX localizes to pericentromeric heterochromatin, contributing to DNA double-strand break repair, DNA replication, and telomere maintenance. During mitosis, most ATRX proteins are removed from chromosomal arms, leaving a pool near the centromere region in mammalian cells, which is critical for accurate chromosome congression and sister chromatid cohesion protection.

Unlabelled: Hazardous heavy metals, particularly cadmium (Cd), are widely distributed in the environment and cause oxidative stress in various animal and human organs. Clove oil (CLO), a common aromatic spice, has been used as a traditional medication as it has potent anti-inflammatory, antioxidant, and hepatoprotective properties.

Background/objectives: This study aimed to investigate the antioxidant, antiapoptotic, and anti-inflammatory effects of clove oil (CLO) against hepatorenal toxicity induced by cadmium (Cd).
