BDNF and Insulin resistance: Pearson’s correlation analysis shows that the degree of insulin resistance correlates negatively with the expression of Bdnf, Naat16, Syn1, Tmcc2, Trkb, and Zpr1, and positively with App mRNA levels when considering the HF60 group; and negatively with Bdnf, Naat16, Tmcc2, and Zpr1 when considering the HF45 group.
