JTT-553, a new DGAT1 blocker, improves blood sugar control in obese and diabetic mice

Updated

Abstract

JTT-553 reduced body weight gain and fat weight in diet-induced obesity mice.

  • JTT-553 decreased insulin, non-esterified fatty acid, total cholesterol, and liver triglyceride levels in non-fasting DIO mice.
  • In DIO mice, JTT-553 improved insulin-dependent glucose uptake in adipose tissues and alleviated glucose intolerance.
  • In KK-A(y) mice, JTT-553 lowered glucose, non-esterified fatty acid, total cholesterol, and liver triglyceride levels in both fasting and non-fasting conditions.
  • JTT-553 reduced TNF-α mRNA levels while increasing GLUT4 mRNA levels in adipose tissues of KK-A(y) mice.
  • These findings indicate potential improvements in insulin resistance and glucose metabolism associated with JTT-553.
