The global incidence of biliary tract cancer (BTC) is on the rise, presenting a substantial healthcare challenge. The integration of immune checkpoint inhibitors (ICIs) with molecularly targeted therapies is emerging as a strategy to enhance immune responses. However, the efficacy and underlying mechanisms of these treatments in BTC are still largely unexplored.

Tryptophan (Trp) is an essential amino acid obtained from human diet. It is involved not only in de novo biosynthesis of proteins but also in complex metabolic pathways. Redox transformation of tryptophan is under-explored in comparison with kynurenine, serotonin and indole pyruvate pathways.

In a recent paper, I noted how healthcare professionals and institutions that appear to value and vaunt kindness can, in practice, fall not just occasionally short, but often systemically so. Rather than insisting on these as aberrations, I wondered whether, our practice of kindness may, as with use of antibiotics or X-rays, have its own less considered but nonetheless harmful side effects.

Objectives: With the aging population, the incidence of intervertebral disc degeneration (IDD) is increasing every year. The pathogenesis of IDD is complex, and there are currently no effective treatment options. This study aims to investigate the specific function and underlying mechanism of zinc finger protein 667 (ZNF667) in the inflammatory damage of nucleus pulposus cells in IDD.

Through long-term coevolution with host plants, insects have evolved sophisticated detoxification systems to counteract plant secondary metabolites (PSMs). However, the precise mechanisms underlying these adaptations remain incompletely characterized. Our previous research identified epsilon glutathione S-transferases (GSTes) as critical mediators of xanthotoxin adaptation in Spodoptera litura, a model linear furanocoumarin.
