Abstract

Objective: To investigate Mitogen Activated Protein Kinase 4 (MAP4K4) and Hypoxia-inducible in peripheral blood of patients with locally advanced cervical cancer the relationship between the expression of factors 2α, HIF-2α and autophagy overactivation and sensitivity to platinum-type neoadjuvant chemotherapy. Methods: 230 patients with locally advanced cervical cancer admitted to our hospital from August 2017 to September 2020 were prospectively selected as research objects. The expression of MAP4K4, HIF2α and autophagy related genes (LC-3 II, LC-3 I and Beclin-1) in peripheral blood before and after chemotherapy were detected by qRT-PCR. Pearson test was used for correlation analysis. The independent risk factors of chemotherapy sensitivity was analyzed by logistics regression model. Results: The expression of MAP4K4 and HIF2α in peripheral blood of patients with locally advanced cervical cancer was observed among subgroups of age, tumor size and histological type (P>0.05), but was observed among subgroups of differentiation, FIGO stage and lymph node metastasis (P<0.05). Before chemotherapy, MAP4K4 mRNA and HIF2α mRNA in peripheral blood of the two groups were compared (P>0.05). After chemotherapy, MAP4K4 mRNA and HIF2α mRNA in both groups were significantly decreased (P<0.05), and MAP4K4 mRNA and HIF2α mRNA in the effective group were significantly lower than those in the ineffective group (P<0.05). Before chemotherapy, LC-3 II, LC-3 I and Beclin-1 were compared between the two groups (P>0.05). After chemotherapy, LC-3 II, LC-3 I and Beclin-1 in both groups were increased, and LC-3 II, LC-3 I and Beclin-1 in ineffective group were significantly higher than those in effective group (P<0.05). MAP4K4 and HIF2α were significantly positively correlated with LC-3 II, LC-3 I and Beclin-1 (P<0.05). Differentiation degree, FIGO stage, lymph node metastasis, LC-3 II, LC-3 I, Beclin-1, MAP4K4 and HIF2α were independent risk factors for chemotherapy sensitivity in patients with locally advanced cervical cancer (P<0.05). Conclusion: The up-regulated expression of MAP4K4 and HIF2α in patients with locally advanced cervical cancer is closely related to over-activation of autophagy during chemotherapy and sensitivity to platinum neoadjuvant chemotherapy.
