Collectively, NAD + exerts its effects not through traditional receptor binding but through its indispensable role as a co-substrate and regulator of these enzymatic systems, which sense and respond to fluctuations in NAD + levels to coordinate cellular metabolism, survival, DNA repair, signaling, and cell fate decisions 1-4
Nonketotic hyperosmolar coma and frusemide therapy
The regulation of the VHLHIF pathway is also related to iron metabolism and ferroptosis in ccRCC, as iron levels are significantly higher in RCC cells and the tumor microenvironment than in normal renal tissue (77), and as HIF-1 mediates the cellular upregulation of TfRC and heme oxygenase (HO) expression, promoting cellular iron accumulation (78, 79)
Through dietary manipulation of tryptophan, an increase in 3-IAA production enhances chemotherapy efficacy by disrupting cancer cell metabolic fitness via increased reactive oxygen species and reduced autophagy
Mingsheng Liu, Chenxiang Xu and Hongqing Zhou performed the experiments
