مستخلص: | Liver cancer is one of the most common malignancies that is difficult to treat due to late diagnosis and chemo-resistance. In the present study, we developed and validated a cell based split nanoLuc biosensor to monitor the Apaf1-Apaf1 interactions in response to apoptosis-inducing drugs such as cisplatin. We showed that the activity of split nanoLuc is reconstituted only in response to apoptotic inducer, cisplatin and in a dose-dependent manner. Apaf1 mutants which were unable to oligomerize failed to recover nanoLuc activity while constitutively active variant increased the nanoLuc activity. Generation of Apaf1 knockout HepG2 and treatment with cisplatin showed dramatic reduction in cell death suggesting that cisplatin mainly targets liver cancer cells through apoptosis. As the natural products are potent sources of compounds for adjuvant therapy, we screened a collection of natural products and identified lentinan as an inducer of apoptosome formation, a key step for induction of apoptosis. Lentinan is a polysaccharide with antitumor, pro-apoptotic properties that functions with poorly understood mechanisms. Lentinan was shown to have cytotoxic effects with the IC Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
