ABSTRACT
<p><b>OBJECTIVE</b>To investigate the mRNA and protein expression levels of cysteine-rich secretory protein 2 (CRISP2) in the sperm of asthenospermia patients, and explore their relationship with sperm motility and related molecular mechanism.</p><p><b>METHODS</b>We collected 78 semen samples from adult male patients with asthenospermia and another 70 from healthy volunteers as controls. We extracted total RNA and total protein from the sperm following purification of the sperm by Percoll gradient centrifugation, and detected the relative expressions of CRISP2 mRNA and protein in the two groups by RT-PCR, SYBR Green real-time PCR and Western blot.</p><p><b>RESULTS</b>The expression of CRISP2 mRNA was down-regulated by 4.3 times and that of the CRISP2 protein by 1.71 times in the asthenospermia patients, significantly lower than in the normal control group (P < 0.05).</p><p><b>CONCLUSION</b>The down-regulation of CRISP2 mRNA and protein expressions in the sperm of asthenospermia patients may be closely related with decreased sperm motility, which suggests that CRISP2 may serve as a potential molecular target for the research of asthenospermia.</p>
