ABSTRACT
This study aimed to analyze the effect and mechanism of immunization of oral KISS1 DNA vaccine on the proliferation of goat testicular Leydig cells. Ten 8-week-old male goats were randomly divided into KISS1 DNA vaccine and control groups for immunization (five goats each group). These goats were sacrificed at 8 weeks after primary immunization, and the tissue samples of hypothalamus, pituitary, and testis and Leydig cell samples were collected for RT-PCR and CCK8 assay. Immunization with the oral KISS1 DNA vaccine effectively inhibited the proliferation of Leydig cells, the expression of hypothalamus KISS1, GPR54, and GnRH mRNA, pituitary GnRHR and LH mRNA, testicular LHR mRNA, and apoptosis-inhibitory gene Bcl-2 mRNA in Leydig cells. By contrast, the immunization enhanced the mRNA expression of apoptosis-promoting gene Bax and Clusterin in Leydig cells. These findings indicate that immunization with the oral KISS1 DNA vaccine can inhibit the proliferation of goat testicular Leydig cells mainly via the hypothalamic-pituitary-testicular axis and apoptosis-related genes.
