摘要:

几乎90%以上的宫颈癌都有高危人乳头瘤病毒(high risk human papilloma virus,HR-HPV)的持续感染,尤其当患者感染HPV16时,高级别宫颈上皮内瘤变或宫颈癌的发生风险可进一步上升。研究表明人类肿瘤中存在低氧现象,缺氧诱导因子1α(hypoxia-inducible factor-1α,HIF-1α)与低氧微环境关系最为密切,HIF-1α的活化能促进肿瘤生长,已成为目前的研究热点。经典的磷脂酰肌醇3激酶(phosphoinositide 3-kinase,PI3K)/蛋白激酶B(protein kinase B,Akt)自噬通路抑制自噬,并且在多种人类肿瘤中表达失调,其异常活化使细胞异常增殖、分化,促进肿瘤生长。综述HPV16感染可能引起HIF-1α与PI3K/Akt自噬通路变化的不同机制,探讨HPV16相关宫颈癌中PI3K/Akt自噬通路及HIF-1α的表达意义。

Abstract:

Almost 90% of cervical cancer has the high risk of human papilloma virus (HR-HPV) persistent infection. The risk of high-grade cervical intraepithelial neoplasia or cervical cancer can be further increased in patients with HPV16 persistent infection. Studies have shown that hypoxia exists in human tumors. Hypoxia-inducible factor-1α (HIF-1α) is closely related to hypoxia microenvironment. The activation of HIF-1α can promote tumor growth, which has become a research hotspot. The classic phosphatidylinositol 3-kinase (PI3K)/ protein kinase B (Akt) autophagy pathway inhibits autophagy, and the expression of this pathway is out of order in a variety of human tumors. Its abnormal activation makes abnormal cell proliferation and differentiation, which promotes the growth of tumor. This article reviews the different mechanisms of HPV16 infection that may cause the changes of HIF-1α and PI3K/Akt autophagy pathways, and their relationship in cervical cancer.
