Fig. 7. Effects of GRg3 on the expression of tumor necrosis factor- α (TNF-α), interleukin-1β (IL-1β), and cyclooxygenase-2 (COX- 2) mRNAs in rats with LPS-induced hippocampal impairment. PCR bands on agarose gel and their relative intensities are indicated in (A) and (B), respectively. The expression levels of TNF-α, IL- 1β and COX-2 mRNAs were normalized to that of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) mRNA as an internal control. ^*p<0.05 and ^**p<0.01 vs. LPS group; ^##p<0.01 vs. LPS group.
