Asprosin在生殖细胞发育中作用的研究进展

Research progress on the role of Asprosin in germ cell development

Asprosin是由140个氨基酸组成的蛋白类激素,主要由白色脂肪组织分泌。多囊卵巢综合征(PCOS)和精子无力症是影响生育的常见疾病。Asprosin通过促进卵泡刺激素(LH)诱导小颗粒细胞雌二醇的生成和胰岛素样生长因子1(IGF-1)诱导小颗粒细胞孕酮的生成等方式调节卵巢内卵泡的生长和优势卵泡排卵。Asprosin作用于下丘脑和睾丸,调节性激素的合成和促进生殖细胞对营养物质的摄取,增加精子的数量、存活率和运动能力。Asprosin参与调节卵泡的生长和精子的发生,为不育症的治疗提供新的策略和靶点。

Asprosin is a protein-like hormone composed of 140 amino acids,which is mainly secreted by adipocytes.Polycystic ovary syndrome(PCOS)and asthenospermia are common causes of infertility.Asprosin promotes the production of estradiol in small granular cells induced by follicle stimulating hormone(FSH)and progesterone in small granular cells induced by insulin-like growth factor 1(IGF-1),which functions in the growth of ovarian follicles and ovulation of dominant follicles.Asprosin promotes the secretion of sex hormones and the production of nutrients,increasing the number,survival time and motility of sperms by acting on the hypothalamus and testicles.Asprosin is involved in regulation of follicle growth and spermatogenesis,so this finding may potentially support the development of new strategies for the treatment of infertility.
