Effects of GV20 acupuncture stimulation on the expression of vesicular acetylcholine transporter (VAChT), choline transporter 1 (CHT1) and muscarinic acetylcholine receptor type 1 (mAChR-M1) mRNAs 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 VAChT, CHT1 and mAChR-M1 mRNAs were normalized to that of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) mRNA as an internal control. ^* p < 0.05, ^** p < 0.01, ^*** p < 0.001 vs. the SAL group; ^# p < 0.05, ^## p < 0.01 vs. the SCO group.
