Abstract:
Objective:To compare the differentially expressed proteins in mice with kidney-yang deficiency and those with kidney-yin deficiency induced by hydrocortisone, and explore the similar and different material bases of male infertility caused by the two types of kidney deficiency.
METHODS:Thirty Kunming mice were equally randomized into a normal control, a kidney-yang deficiency and a kidney-yin deficiency group. The animals of the normal control group were injected intraperitoneally with normal saline at 0.2 ml qd for 7 days, while those of the latter two groups with hydrocortisone at 25 mg/kg/d for 10 days and 50 mg/kg/d for 7 days, respectively, for establishment of kidney-yang deficiency and kidney-yin deficiency models. Then the pathological changes in the testicular tissue of the mice were observed by HE staining and the differentially expressed proteins were compared among different groups using isobaric tags for relative and absolute quantitation (iTRAQ) and the bioinformatics method.
RESULTS:Sod1 was found to be a reproduction-related node protein differentially expressed in the testis tissues of the two types of kidney-deficiency mice, more highly expressed in the kidney-yin than in the kidney-yang deficiency group (P < 0.05). Five reproduction-associated node proteins were co-expressed in the testes of the two groups of kidney-deficiency mice, with significantly up-regulated expression of Rps28 and down-regulated expressions of Rpl11, Rplp2, Svs2 and Svs3a (P < 0.01).
CONCLUSIONS:Sod1 may be one of the key material bases for the differentiation of male infertility caused by kidney-yang deficiency from that induced by kidney-yin deficiency, while Rps28, Rpl11, Rplp2, Svs2 and Svs3a may be the common material bases of male infertility caused by the two types of kidney deficiency.
