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.

Calebin A mitigates oxidative stress and inflammation in diabetic nephropathy via Nrf2/HO‐1 and NF‐κB signaling pathways

Journal of Diabetes Investigation, EarlyView.
Representative histological images of kidney tissues stained with hematoxylin and eosin (H&E) at 400× magnification (n = 6). ABSTRACT Background Diabetic nephropathy (DN) is a common and serious microvascular complication of diabetes mellitus, primarily driven by persistent hyperglycemia‐induced oxidative stress and chronic inflammation.

Plastid genome structure and phylogenomics of the freshwater red algal order Batrachospermales (Rhodophyta)

Journal of Phycology, EarlyView.
Abstract For the freshwater red algal order Batrachospermales, the number of plastid genomes available is relatively small compared to the number of genera. Fully assembled plastid genomes can provide insights into plastid evolution and crucial data for phylogenetic reconstruction.

Harnessing blue light photobiomodulation for cancer therapy: Evidence from a systematic review

Photochemistry and Photobiology, EarlyView.
Conventional treatments for various types of cancer are often associated with tumor recurrence and aggressiveness. Photobiomodulation with blue light (BL; 450–470 nm) emerges as a promising alternative with antitumor effects. This systematic review, with 37 in vitro and in vivo studies from 2002 to 2024, revealed that BL reduces cell viability ...

Optimization of photobiomodulation therapy for spinal cord injury: A review

Photochemistry and Photobiology, EarlyView.
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

Comparison of HMOX1 expression and enzyme activity in blue-shelled chickens and brown-shelled chickens

Genetics and Molecular Biology, 2013
Blue egg coloring is attributed to biliverdin derived from the oxidative degradation of heme through catalysis by heme oxygenase (HO). The pigment is secreted into the eggshell by the shell gland.
