ICV injection of orexin-A increases mRNA expression of CaMKIIa and CamKIIb in the PVN of SD rats. Adult male SD rats received ICV injection of either orexin-A or vehicle control. The rats were euthanized 3 h following microinjection, and PVN tissue was harvested and subjected to real-time PCR to measure mRNA expression of CaMKIIa (A) and CaMKIIb (B). The data were normalized to GAPDH mRNA and the average mRNA levels in control rats were assigned an arbitrary unit of 1 (n = 5/group). P = 0.006 for the CaMKIIa mRNA (A) increase and P = 0.022 for the CaMKIIb mRNA (B) increase. * P < 0.05.
