The aim of current study was to explore the mechanism of miR-142-5p in cervical cancer through mediating the PIK3AP1/P13K/AKT axis. To this end, RT-qPCR and Western blot analysis results revealed that miR-142-5p was poorly expressed, whereas PIK3AP1 was highly expressed in cervical cancer tissues and cells. Furthermore, miR-142-5p was hypermethylated in cervical cancer, as reflected by MS-PCR and ChIP assessment of enrichment of DNMT1/DNMT3a/DNMT3b in the promoter region of miR-142-5p. A target binding relationship between miR-142-5p and PIK3AP1 was established, showing that miR-142-5p targeted and inhibited the expression of PIK3AP1. Loss- and gain- function assays were conducted to determine the roles of miR-142-5p and PIK3AP1 in cervical cancer cells. CCK-8, flow cytometry and Transwell assay results revealed that overexpression of miR-142-5p in cervical cancer cells downregulated PIK3AP1 and inhibited the P13K/AKT signaling pathway, leading to reduced proliferation, migration, and invasion capacity of cervical cancer cells, but enhanced apoptosis. Collectively, epigenetic regulation of miR-142-5p targeted PIK3AP1 to inactivate the P13K/AKT signaling pathway, thus suppressing development of cervical cancer, which presents new targets for the treatment of cervical cancer.

Dehydrocostus Lactone

ObjectivesRecent studies found that dehydrocostus lactone (DHC), a traditional Chinese medicine in curing chronic ulcer and inflammation, can inhibit several type of tumor cells. The purpose of this study was to define the role of DHC on cervical cancer cells and to explore its mechanism of action.MethodsWe used DHC alone or in combination with PI3K/Akt-specific inhibitor LY294002 (LY) to treat Hela cells [human papillomavirus (HPV)-18 positive] and C33a cells (HPV negative). The proliferation, apoptosis, and Akt activation were assessed. Cell invasive ability was assayed in transwell chambers.ResultsWe found that DHC significantly inhibited proliferation, antiapoptosis, and invasion of both cells, and reduced the level of p-Akt phosphorylation in these cells, in a dose- or time-dependent manner. In addition, these inhibitions of DHC were significantly strengthened by LY.ConclusionsThe result suggested that DHC plays a potent role in anticervical cancer in multiple biological aspects through PI3K/Akt signaling pathway, independently of HPV infection. This finding surely adds new knowledge to understand the role of DHC in fighting cancers.

Cervical cancer is one of the most malignant cancers of the female reproductive system with high morbidity and mortality. In the current study, we have examined the effect of eriodictyol on cell survival including cell growth, cell cycle and apoptosis of cervical cancer cells and also explored the underlying mechanism(s). To this end, CCK-8 assay, flow cytometry and western blotting assays were performed in cervical cancer HeLa cells. Eriodictyol significantly inhibited cell survival including impeding the cell viability, arresting the cell cycle at the G1 phase and potentiating cell apoptosis in a concentration-dependent manner. Also, ERI activated PTEN, P21, cleaved caspase-3/-9 expression and downregulated P-Akt and cyclin D1 expression in a dose-dependent manner. In conclusion, ERI can inhibit cervical cancer HeLa cells viability via impeding cell cycle and inducing apoptosis by regulating PTEN/Akt signaling pathway.
