Verification of differential expression of NGFR and SOD2. The differentially expressed NGFR and SOD2 identified through transcriptomic studies were verified in sMC, SB, and sPB. With qRT-PCR, transcript of NGFR was shown to be significantly down-regulated in sMC-FET (p < 0.01), sMC-MAT (p < 0.05), SB (p < 0.05), but up-regulated in sPB (p < 0.01). The transcript of SOD2 was up-regulated in all sMC-FET (p < 0.01), sMC-MAT (p < 0.01), SB (p < 0.05), and sPB (p < 0.01).
