Expression and regulation of HES1 in sperms with low motility from asthenospermia patients / 基础医学与临床

ABSTRACT

Objective To analyze the expression and regulation of HES1 in sperms with low motility.Methods Thirty semen samples from asthenospermia patients and 20 semen samples from healthy and fertile adults were collected,total RNAs were extracted to produce cDNAs probes.Hybridization with Phalanx OneArray~(TM) containing 30 968 probes was carried out after the labeled cDNAs were purified by PCR product purification kit.Realtime RT-PCR was used to analyze the expression of hsa-miR-487a and hsa-miR-193b;the expression of the target genes of hsa-miR-487a and hsa-miR-193b were searched from gene-expression profiles in asthenospermia patients' sperms.Results The expression level of HES1 in low motility sperms was up-regulated.The expression level of hsamiR-193b in low motility sperms was 2.19 times higher than that in high motility sperms,hsa-miR-487a was 0.43% of that in high motility sperms.Conclusion The expression level of HES1 in low motility sperms was up-regulated.Hsa-miR-487a and hsa-miR-193b may affect the expression of HES1 and so regulate sperm motility.
