Elevated glucose-6-phosphate dehydrogenase expression in the cervical cancer cases is associated with the cancerigenic event of high-risk human papillomaviruses

The most important etiologic agent in the pathogenesis of cervical cancers (CCs) is human papillomavirus (HPV), while the mechanisms underlying are still not well known. Glucose-6-phosphate dehydrogenase (G6PD) is reported to elevate in various tumor cells. However, no available references elucidated the correlation between the levels of G6PD and HPV-infected CC until now. In the present study, we explored the possible role of G6PD in the pathology of CC induced by HPV infection. Totally 48 patients with HPV + CC and another 63 healthy women enrolled in the clinical were employed in the present study. Overall, prevalence of cervical infection with high-risk-HPV (HR-HPV) type examined was HPV-16, followed by HPV-18. The expressions of G6PD in CC samples were also detected by immunohistochemistry (IHC), qRT-PCR, and Western blot. Regression analysis showed elevated G6PD level was positively correlated with the CC development in 30–40 aged patients with HR-HPV-16/18 infection. The HPV16 + Siha, HPV18 + Hela,...
