EVALUATING THE mRNA EXPRESSION LEVEL OF SPAG8 GENE IN MALE INFERTILITY
Main Article Content
Abstract
The regulation of spermatogenesis and sperm differentiation is controlled by different types of gene. SPAG8 (sperm associated antigen 8) is a gene involving in the regulation process but the role of this gene remains unclear. Objectives: Evaluating the mRNA expression level of SPAG8 gene in blood samples from infertile males. Material and methods: total RNA from 50 peripheral blood samples (25 samples of infertile males, 25 samples of control group) were extracted. The mRNA expression level of SPAG8 gene were determined using RT-qPCR assay. Results: The average mRNA expression level of SPAG8 gene in infertile males = 0.8205±1.316 (0.091 – 3.977). The average mRNA expression level of SPAG8 gene in the control group = 1,418±1,115 (0.306 – 3.464). The mRNA expression level of the SPAG8 gene of the male infertility group was lower than the control group, the difference was statistically significant with p<0.05. Conclusion: Initial study has shown that the expression level of SPAG8 gene in peripheral blood is lower in male infertility patients than in control group, suggesting a correlation between this gene and male infertility.
