Juglone inhibits proliferation of HPV-positive cervical cancer cells specifically

Abstract

Human papillomaviruses (HPVs), such as HPV 16 and HPV 18 are related to cervical cancer. Therefore, it is important to inhibit HPV-positive cervical cancer for treating cervical cancer. This study is aiming at investigating the proposed molecular mechanism, which underlies the antineoplastic potential of the aqueous extract of juglone of HPV-positive cervical cancer cells. According to the results, it is showed that, juglone prohibited HPV positive cervical cancer cells’ growth through dose-dependent way. Nevertheless, when pin 1 was knocked down, the proliferation inhibition reduced. The detection of apoptosis and cell cycle also illustrated that juglone influenced HPV positive cells. Western blot expressed the influence mechanism that it affected the B-cell lymphoma 2 (Bcl-2) family and later activated the Caspase-depended apoptosis way. It is contributable for this study to understand the mechanism of inhibiting HPV positive cells by juglone and it also provides an effective strategy for the application of it in the future.
