“…injection of recombinant gNPY inhibited the PSSI gene expression in hypothalamus in vivo. This is somewhat similar to the previous study that the SS-14 release was inhibited by NPY in the trout pancreas in vitro [20]. Up to now, there are scarce reports about the relationship between NPY and PSSI, and additional studies are warranted to elucidate the precise role of NPY on PSSI gene expression.…”
