In 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. ⋯ In 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.
