Fig 1: Electroacupuncture increases NPY expression in PVN of 2K1C rats. (a) NPY mRNA quantification within the PVN in each group. (b) NPY mRNA levels in the cerebral cortex from the same brain sections used for PVN assessment in each group. (c) NPY Y1R mRNA quantification within the PVN in each group. (d) NPY Y5R mRNA quantification within the PVN in each group. (e) NPY protein amounts within the PVN in each group. (f) NPY protein amounts in the cerebral cortex. (g) NPY Y1R protein amounts within the PVN in each group. (h) NPY Y5R protein amounts within the PVN in each group. Data were expressed as mean ± SE; n = 6; *P < 0.05 and **P < 0.01 versus the sham group; #P < 0.05 and ##P < 0.01 versus the 2K1C group.
