胰岛素抵抗(insulin resistance，IR)与多囊卵巢综合征(polycystic ovary syndrome，PCOS)的发生发展有关，而与IR相关的胰岛素信号通路异常会引起卵巢局部代谢紊乱，进而影响卵泡发育及卵子质量。PCOS卵巢颗粒细胞中胰岛素作用的经典通路，包括磷脂酰肌醇3激酶(phosphoinositide 3-kinase，PI3K)/蛋白激酶B(protein kinase B，Akt)通路和丝裂原激活的蛋白激酶(mitogen-activated protein kinase，MAPK)/细胞外信号调节激酶(extracellular signal-regulated kinase，ERK)通路;与炎症相关的通路包括Toll样受体(Toll-like receptor，TLR)/核因子κB(nuclear factor-κB，NF-κB)通路等;氧化应激相关通路包括核转录因子红系2相关因子2(nuclear factor-erythroid 2-related factor 2，Nrf2)/血红素加氧酶-1(heme oxygenase-1，HO-1)途径和GTP酶免疫相关蛋白7(GTPase of immunity-associated protein 7，GIMAP7)/音猬因子(sonic hedgehog，SHH)途径;与脂质代谢相关的通路如激活转录因子4(activating transcription factor 4，ATF4)通路等。明确PCOS患者卵巢颗粒细胞中IR相关信号转导通路，增进PCOS病理生理机制的认识，进一步为PCOS的治疗提供新思路。
Pathways of Insulin Resistance in Ovarian Granulosa Cells of Polycystic Ovary Syndrome Patients
Insulin resistance(IR)is associated with the genesis and development of polycystic ovary syndrome(PCOS).The abnormity of insulin-related signaling pathways causes metabolism disorder,which affects follicle development and quality.In ovarian granulosa cells of PCOS,the classical pathways of insulin include phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)and mitogen-activated protein kinase(MAPK)/extracellular signal-regulated kinase(ERK).The pathways related with inflammation include Toll-like receptor(TLR)/nuclear factor-κB(NF-κB),and the pathways of oxidative stress include nuclear factor-erythroid 2-related factor 2(Nrf2)/heme oxygenase-1(HO-1)and GTPase of immunity-associated protein 7(GIMAP7)/sonic hedgehog(SHH).There are multiple pathways related with metabolism,such as the lipid metabolism-related pathway of activating transcription factor 4(ATF4).Therefore,clarifying the IR-related signal transduction pathway and molecular mechanism in ovarian granulosa cells of PCOS patients can supplement the knowledge of PCOS pathogenesis,and further provide new ideas for the treatment of PCOS.
