Abstract Phyllanthus amarus is widely grown in this sub-continent and used traditionally to treat many common ailments. In the present study, lignan rich fraction of P. amarus extract was used on cervical cancer cell lines (HeLa, SiHa and C33A) to study it’s mechanism of cell death induction. As the cells were treated with IC50 doses of LRF, characteristic apoptotic features were observed. Increased sub G0 population were observed both in Hela and C33 cells, while G1/S arrest was observed in SiHa cells than their untreated counterparts. Increased production of ROS and change in MMP were also detected in the treated cells. Presence of γH2AX, was observed by immunofluorescence. Reduced expression of HPV (16/18) as well as ET-1, an autocrine growth substance, were observed in the treated cells. Immunoblotting as well as ICFC studies showed enhanced expressions of BAX, Caspase 3 and PARP (cleaved) in the treated cells. A major lignan, phyllanthin was isolated from the chloroform fraction and showed strong irreversible affinities for viral E6 and MDM2 in in silico analysis. The study conclusively indicates that LRF has the potential to induce apoptotic cell death in cervical cancer cells by activation of p53 and p21 against DNA damage.

IntroductionIn this study, we analyzed the effect of plumbagin (PL) on cultured SiHa cervical cancer cells using fluorescence microscopy and flow cytometry techniques to identify the mode of cell death and to elucidate whether cells die through apoptosis or non-apoptosis.Material and methodsThe cell death was analyzed using MTT assay. The cellular morphological changes were assessed using acridine orange/ethidium bromide dual staining. DNA damage and cell cycle progression were analyzed using a comet assay and flow cytometry respectively.ResultsMorphological and cytological features revealed that PL induced autophagic cell death in cancer cells. The results of a cell cycle analysis indicated that the proportion of cells in sub-G0 phase increased. Translocation of LC-3B protein from the cytoplasm to the autophagosome was found in 31% of PL-treated cells, suggesting that PL provoked autophagic cell death. In this study, it was observed that plumbagin treatment caused cleavage of DNA in SiHa cancer cells, and morphological analysis provided very strong evidence supporting the occurrence of autophagic cell death as a result of plumbagin treatment.ConclusionsIn addition, a Cytoscape-based protein-PL interaction network analysis provided very strong evidence in support of the specific mode of cell death in the context of autophagy, which has also been one of the desired endpoints in human papillomavirus-positive cervical cancer therapy and apoptotic cell death-resistant cancer treatment. Thus, this study is the first to test PL against the SiHa cervical cancer cell line, providing leads for further testing on non-apoptotic cell death for application in cervical cancer management.
