We have obtained experimental evidence that KBH-1, including onji-saponin B and curcumin, improves the hepatic steatosis and leptin resistance of hypothalamus in an HFD-induced obesity rat model by up-regulating the activation of AMPK and suppressing the expression of PPARγ in the liver and enhancing the leptin-mediated signals in the hypothalamus. Here, PPARG is linked to Obesity.
