Abstract:

To explore the pathogenesis of the rooster asthenospermia,the expression profiles of 6 candidate genes (COX7BPTGDShPGDSSPAG6,WNT2 and CCNF) selected from the previous digital gene expression profiling (DGE) and bioinformatics analysis,were analyzed.A total of 300 Beijing-You roosters of 42 weeks were detected for 4 weeks for semen quality including semen volume,sperm mobility,etc.Fifteen asthenospermia and 15 normal roosters were selected accordingly.Real-time quantitative PCR were performed to determine the expression of the 6 genes in the testicular of those roosters.The results indicated that COX7B and PTGDS were significantly high-expressed in the asthenospermia group (P<0.01),while the WNT2,hPGDS and CCNF were significantly low-expressed in the asthenospermia group (P<0.05).However,the expression of SPAG6 gene was not significantly different in the 2 groups.These results were in accordance with the previous DGE analysis.The expression patterns of the 6 genes identified from DGE for asthenospermia in chickens were validated in the present study.They can be important candidate genes for further functional study and revealing the mechanism of chicken asthenospermia.
