Effects of GV20 acupuncture stimulation on the expression of brain-derived neurotrophic factor (BDNF) and cAMP-response element-binding protein (CREB) mRNA in rats with SCO-induced hippocampal impairment (n = 3/group). PCR bands on agarose gel and their relative intensities are shown in (A) and (B), respectively. The expression levels of BDNF and CREB mRNA were normalized to that of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) mRNA as an internal control. ^** p < 0.05, ^*** p < 0.001 vs. the SAL group; ^# p < 0.05 vs. the SCO group.
