Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

The FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

The FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

GCN2 in proteostasis: structural logic, signalling networks and disease

The FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Sacubitril/Valsartan Attenuates Inflammation and Fibrosis Associated With Decreased Integrin α8 and Inhibits Hepatocarcinogenesis in a Rat Model of Metabolic Dysfunction‐Associated Steatohepatitis

Hepatology Research, EarlyView.
Sacubitril/Valsartan (Sac/Val) alleviates fibrosis and inflammation in metabolic dysfunction‐associated steatohepatitis (MASH). Its anti‐fibrotic effect is linked to the suppression of Integrin alpha 8 (Itga8), a protein crucial for hepatic stellate cell (HSC) activation and collagen production.

USP18 mediates high glucose‐induced cardiomyocyte injury by regulating the JAK/STAT signaling pathway through stabilizing FOXC2 expression

Journal of Diabetes Investigation, EarlyView.
USP18 upregulation stabilizes FOXC2 expression by deubiquitination to inactivate the JAK2/STAT3 pathway, thereby inhibiting HG‐induced NMVM apoptosis, inflammation, oxidative stress, and fibrosis. ABSTRACT Background Cardiomyopathy is one of the complications of diabetes, among which myocardial fibrosis is the most typical feature.
