英文摘要Protein kinase 2 subunit alpha 2 (CK2 alpha'), a serine/threonine-selective protein kinase, is associated with sperm apoptosis. However, the presence of CK2 alpha' in ram sperm during the freezing-thawing process has not been previously reported. Thus, this study was conducted to determine the effect of cryopreservation on the association between CK2 alpha' and ram sperm function. Sperm variables, including sperm motility, DNA damage and acrosome integrity, were measured in fresh (F), cooled (CO) and freeze-thawed (FT) sperm. Sperm proteins and total mRNA were extracted form cells of each group, and subjected to western blot and real-time PCR analysis for detection of CK2 alpha' proteins and relative abundance of mRNA. The distribution pattern of CK2 alpha' protein in ram sperm was also monitored in each group using an immunofluorescence technique. The results provided evidence that the freeze-thaw process has an impact on ram sperm variables, and the normalized CK2 alpha' protein and relative abundance of CK2 alpha' mRNA were both significantly less in FT than F sperm. The amount of CK2 alpha' in FT extended seminal plasma was increased as compared with F samples. Furthermore, immunofluorescence revealed that CK2 alpha' was distributed throughout the acrosome of ram sperm. The association of CK2 alpha' with DNA damage and acrosome integrity was confirmed using Pearson's linear correlation. In conclusion, the understanding the molecular effects of cryopreservation on CK2 alpha' in ram sperm could provide insight into methods for improving fertility associated with frozen-thawed ram sperm.
