Biosynthesis of microcystin hepatotoxins in the cyanobacterial genus Fischerella [PDF]
Toxicon, 2018 Microcystins (MCs) are serine/threonine phosphatase inhibitors synthesized by several members of the phylum Cyanobacteria. Mining the draft genome sequence of the nostocalean MC-producing Fischerella sp. strain CENA161 led to the identification of three contigs containing mcy genes.

Advanced Science, EarlyView.This study identifies C4 as a lead inhibitor of the Lpt system. Notably, C4 potentiates colistin activity by disrupting LPS transport and remodeling phospholipid homeostasis, revealing a functional interplay between the Lpt and Mla systems. These findings establish a mechanistic link between Lpt inhibition and membrane lipid remodeling, positioning Lpt–

Animal Models and Experimental Medicine, EarlyView.DPSCs, hepatocytes, and exosomes were tested for liver fibrosis therapy. Exosome‐based treatment exhibited superior antioxidative and regenerative effects. Liver enzymes, oxidative stress, and profibrotic markers were significantly reduced. α‐SMA, desmin, and related gene expression were downregulated.

A 57 year old man with chronic renal failure and cardiac tamponade who developed ischemic hepatitis
Annals of Hepatology, 2006 Ischemic hepatitis is an infrequent entity, usually associated with low cardiac out put. We present a case of a 57 year-old man with chronic renal failure and cardiac tamponade who developed elevation of serum alanine transferase level of 5,054 U/L ...
