遺伝子研究の概要
CNDP2, also known as carnosine dipeptidase II, is an enzyme with multiple essential functions. It catalyzes the formation of Lac-Phe, an exercise-induced metabolite from lactate, and is involved in lactate clearance, carnosine hydrolysis, oxidative stress regulation, and metabolite regulation. It is also associated with cardiometabolic, renal diseases, and has implications in cancer-related pathways such as PI3K/AKT, MAPK, and cooperative nutrient scavenging in the tumor microenvironment [1,4,6,9]. Genetic models, like KO mouse models, are valuable for studying its functions.
In KO mouse models, genetic ablation of CNDP2 eliminates tissue amino acid BHB-ylation activity and reduces BHB-amino acid levels, leading to increased food intake and body weight upon ketosis stimuli or exogenous ketone ester supplementation [2,8]. In the context of metformin's action, genetic ablation of CNDP2 in mice renders them resistant to metformin's anorexigenic and anti-obesity effects, establishing the CNDP2/Lac-Phe pathway as a critical mediator of metformin's effects on energy balance [3,7]. Also, CNDP2 KO mice show aggravated hepatic and renal damage upon an acetaminophen overdose, indicating its role in protecting cells under cysteine insufficiency [5].
In conclusion, CNDP2 is a key enzyme in multiple biological processes. Model-based research, especially through KO mouse models, has revealed its role in energy balance, metabolite regulation, and cell protection under stress. In diseases, it is implicated in cardiometabolic, renal conditions, and cancer, highlighting its potential as a therapeutic target.
