Obese Mice Lose a third of their Fat using a natural Protein

ummary of the pathways impacted by chronic BP3 treatment in liver and WAT in obese mouse models. BP3 enhances FGF/FGFR signaling and downstream activation of Akt and IL6/Stat3 that lead to the inhibition of gluconeogenesis, through Ppargc1a/G6pc downregulation. The parallel activation of Akt and Stat3 results in an inhibition of Ppargc1b and/or Srebf1, key regulators of downstream lipogenic enzymes, thus leading to the inhibition of de novo lipogenesis and TG synthesis.

Heat shock proteins ram into other proteins, generating force that is beneficial. Studies at The University of Texas Health Science Center are providing basic new understanding about “heat shock proteins,” also called “chaperone proteins.” These proteins, first identified in cells subjected to heat, are very important under many stressful and non-stressful metabolic conditions. They maintain proper protein function and, importantly, prevent the inappropriate accumulation of damaged proteins...
