Abstract:

To detect the expression pattern of YWHAG(Tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein,gamma polypeptide) gene in during porcine follicle development.The CDS(Coding sequence) of YWHAG gene was cloned from porcine follicular tissue.Semi-quantitative RT-PCR was used to analyze the tissue expression profiling of YWHAG genes,Furthermore the expression level of YWHAG in follicles with different diameter(L,M2,M1,S) from Duroc and Meishan were investigated by real-time fluorescence quantitative PCR.The results showed that:the length of CDS of porcine YWHAG was 780 bp,and it’s similarity with that of human,mouse,and cattle was 97.72%,96.68% and 98.57%,respectively.YWHAG mRNA was expressed in all tested tissues(Muscle,fat,heart,liver,spleen,lung,kidney,stomach,small intestine,ovarian,uterine,uterine horn,tubal,pituitary,corpus luteum,brain,the hypothalamus),and especially high in fat,intestine and brain.Both in Duroc and Meishan swine,the expression of YWHAG mRNA in M1 and L follicles were significantly higher than M2 and S follicles(P<0.05).Moreover,The expression in S and M2 follicles from Meishan were significantly higher than that from Duroc(P<0.01),while no significant difference in M1 and L follicle.In conclusion,YWHAG gene may be involved in the apoptosis of porcine follicular development process,resulting in differences of ovulation rate in swine.
