SLC25A1 and ACLY maintain cytosolic acetyl-CoA and regulate ferroptosis susceptibility via FSP1 acetylation.

Ferroptosis, an iron-dependent form of programmed cell death characterized by excessive lipid hydroperoxides accumulation, emerges as a promising target in cancer therapy. Among the solute carrier (SLC) superfamily, the cystine/glutamate transporter system antiporter components SLC3A2 and SLC7A11 are known to regulate ferroptosis by facilitating cystine import for ferroptosis inhibition. However, the contribution of additional SLC superfamily members to ferroptosis remains poorly understood.

Oxidative stress arises from an imbalance between reactive species (RS) production and the antioxidant defense, increasing the brain susceptibility to neurodegenerative and psychiatric diseases. Besides, changes in the expression or activity of neurotransmitter metabolism enzymes, such as monoamine oxidases (MAO), are also associated with mental disorders, including depression. Considering this, antioxidant and MAO-A activity inhibitory potential of six 2,3-chalcogenodihydrobenzofurans (2,3-DHBF) was investigated through in vitro and in silico tests.

Introduction: Cefiderocol is a parenteral catechol-type siderophore cephalosporin, which has been approved for the treatment of gram-negative bacterial infections. Its activity among the carbapenem-resistant gram negative bacilli (CR-GNBs) in India is largely unknown.
Methodology: We tested in-vitro susceptibility of cefiderocol in 84 CR-GNB [ carbapenem-resistant Acinetobacter baumannii (CRAB), carbapenem-resistant Pseudomonas aeruginosa (CRPA) , carbapenem-resistant Escherichia coli (CREC) and carbapenem-resistant Klebsiella pneumoniae (CRKP)] by broth microdilution(BMD) and disc diffusion (DD) using Clinical and Laboratory Standards Institute (CLSI) and European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints and concordance of DD was compared with BMD.

Pancreatic ductal adenocarcinoma (PDAC) relies heavily on glutamine (Gln) utilization to meet its metabolic and biosynthetic needs. How epigenetic regulators contribute to the metabolic flexibility and PDAC's response and adaptation to Gln scarcity in the tumor milieu remains largely unknown. Here, we elucidate that prolonged Gln restriction or treatment with the Gln antagonist, 6-diazo-5-oxo-L-norleucine (DON), leads to growth inhibition and ferroptosis program activation in PDAC.

Bloodstream infection in neonates is a complicated disease and presents a major challenge both in diagnosis and in therapeutic intervention. The focus of the present study was to investigate the incidence, the species distribution and the risk factors associated with mortality of bloodstream infections in a neonatal intensive care unit (NICU) and evaluating the antifungal susceptibility of traditional antifungal drugs and three nanoparticle-based drug delivery systems based on nanoparticles. A total of 458 patients were evaluated, and 9.
