Pharmacological inhibition of BCKDK using BT2 reduces plasma branched-chain amino acid (BCAA) and branched-chain alpha-keto acid (BCKA) levels, thereby attenuating obesity-associated insulin resistance in obese mice.
In obese individuals, high levels of branched-chain amino acids (BCAAs) and their metabolites contribute to insulin resistance. This study suggests that enhancing the body's ability to break down BCAAs (via BCKDK inhibition) improves insulin sensitivity. While BT2 is a drug, the findings support the idea that managing BCAA metabolism is key to treating obesity-related metabolic issues.
Restoring BCAA catabolic flux with a pharmacological inhibitor of BCKA dehydrogenase kinase (BCKDK) (a suppressor of BCKA dehydrogenase) reduced the abundance of BCAA and BCKA and markedly attenuated IR in ob/ob mice.
Why this rating
Strong experimental evidence in genetically obese (ob/ob) and diet-induced obese (DIO) mouse models with consistent results across multiple metrics.
