Lipidome profiling in advanced metabolic liver disease identifies phosphatidylserine synthase 1 as a regulator of hepatic lipoprotein metabolism.

Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by defective lipid metabolism, which causes disease progression. MASH is also linked to various cardiometabolic risk factors, including obesity and type 2 diabetes. The contribution of defective lipid metabolism in MASH to cardiometabolic comorbidities is incompletely understood.

A composite reference standard is needed for bedaquiline antimicrobial susceptibility testing for complex.

Transcriptomic responses to antibiotic exposure in .

Transcriptional responses in bacteria following antibiotic exposure offer insights into antibiotic mechanism of action, bacterial responses, and characterization of antimicrobial resistance. We aimed to define the transcriptional antibiotic response (TAR) in (Mtb) isolates for clinically relevant drugs by pooling and analyzing Mtb microarray and RNA-seq data sets. We generated 99 antibiotic transcription profiles across 17 antibiotics, with 76% of profiles generated using 3-24 hours of antibiotic exposure and 49% within one doubling of the WHO antibiotic critical concentration.
