CD38 is the main NAD+-hydrolyzing enzyme, and it also catabolizes nicotinamide mononucleotide (NMN) and other extracellular NAD+ precursors prior to their intracellular transport for NAD+ biosynthesis.
Colorectal cancer (CRC) is a heterogeneous malignancy that starts with the sequential transformation of normal mucosa to adenoma and finally to carcinoma, when it attains metastatic potential. The most frequent metastatic site in CRC is the liver. Researchers from Nanjing Medical University and collaborators identified a significant overexpression of procollagen-lysine,2-oxoglutarate 5-dioxygenase 3 (PLOD3) in liver metastasis tissue samples.
Researchers from Third Military Medical University of the Chinese PLA have published data from a study that aimed to investigate the biological functions and molecular mechanisms of tandem C2 domains, nuclear (TC2N) in the development and progression of breast cancer.
It is largely known that the expression of programmed cell death 1 ligand 1 (PD-L1) contributes to immune evasion by cancer cells, thus avoiding the cytotoxic effect exerted by T cells. Therefore, it is important to understand the mechanisms regulating PD-L1 levels.
