Identification of DHA-23, a Novel Plasmid-mediated and Inducible AmpC beta-Lactamase from Enterobacteriaceae in Northern Taiwan

Frontiers in Microbiology, 2015
Objectives: AmpC β-lactamases are classified as Amber Class C and Bush Group 1. AmpC β-lactamases can hydrolyze broad and extended-spectrum cephalosporins, and are not inhibited by β-lactamase inhibitors such as clavulanic acid.

The depletion of serine beta‐lactamase‐like protein (LACTB) ameliorates metabolic dysfunction–associated steatotic liver disease by reducing ubiquitin‐mediated degradation of carnitine palmitoyltransferase 2

Diabetes, Obesity and Metabolism, Volume 28, Issue 4, Page 2962-2977, April 2026.
Abstract Aims Metabolic dysfunction–associated steatotic liver disease (MASLD) represents one of the most common chronic liver disorders worldwide, and its incidence continues to rise each year. Serine β‐lactamase‐like protein (LACTB) is a serine protease that plays a crucial role in lipid metabolism and hepatocellular carcinoma, but its function in ...
