Biochemical and immunological properties of dog brain isorenin.

abstract：:Recently, we demonstrated that estradiol (E(2)) modulates cross-talk between protein tyrosine kinases and norepinephrine (NE) receptor signaling in the hypothalamus (HYP) and preoptic area (POA), brain areas that govern female reproductive function. We are now investigating the identity of protein tyrosine kinase(s) t...
