These findings suggest that NNT loss-of-function blocks the interconversion of NADH to NADPH leading to NADH accumulation and reductive stress
8-Hydroxydeoxyguanosine: a new potential independent prognostic factor in breast cancer
Given the tight coupling between the immunosuppressive TME and its unique metabolic reprogramming (e.g., high glucose consumption, elevated lactate levels, low pH, and hypoxia), interventions targeting metabolism (such as inhibiting lactate production or transport) can not only directly decrease the survival advantages of tumor cells but also significantly increase the function and tumor-infiltrating capacity of effector immune cells, such as CD8 + T cells
