4-Methyl-2-oxopentanoic acid is an abnormal metabolite, a neurotoxin and a metabolic toxin. 4-Methyl-2-oxopentanoic acid increases endoplasmic reticulum stress, promotes lipid accumulation in preadipocytes and insulin resistance by impairing mTOR and autophagy signaling pathways[1] [2].
4-Methyl-2-oxopentanoic acid (0-300μM; 2d) treatment concentration-dependently increased lipid accumulation and the expression of lipogenic proteins, such as processed SREBP1 and SCD1, in 3T3-L1 preadipocytes[1]. 4-Methyl-2-oxopentanoic acid (1-10mM) reduced the HT-22 cells’ metabolic ability to reduce cytotoxicity and increased RS production in hippocampal neurons[2].
Mitochondrial complexes activities were reduced, and the formation of reactive species (RS) was increased in the hippocampus of rats after 4-Methyl-2-oxopentanoic acid (4mol/L, 2μL; ICV) administration[2].4-Methyl-2-oxopentanoic acid（10mmol/l; ICV） stimulated insulin secretion and elevated the NADPH/NADP+ ratio of islets preincubated in the absence of fuel[3].4-Methyl-2-oxopentanoic acid (400μmol/kg/h; carotid arch injection; single dose injection 60 min) increases porcine skeletal muscle protein synthesis and plasma leucine levels[4].
