Lusion test, flow cytometric, Western blot and reverse transcriptase-PCR strategies have been employed. Additional, siRNA transfections and inhibitor research had been applied to validate the involvement of p53 pathway in calcarea carbonica-induced apoptosis in cancer cells. Final results: Interestingly, though calcarea carbonica administration to Ehrlich’s ascites carcinoma (EAC)- and Sarcoma180 (S-180)-bearing Swiss albino mice resulted in 30-35 tumor cell apoptosis, it failed to induce any important cell death in ex vivo circumstances. These outcomes prompted us to examine whether calcarea carbonica employs the immuno-modulatory circuit in asserting its anti-tumor effects. Calcarea carbonica prevented tumor-induced loss of effector T cell repertoire, reversed type-2 cytokine bias and attenuated tumor-induced inhibition of T cell proliferation in tumor-bearing host. To confirm the part of immune program in calcarea carbonica-induced cancer cell death, a battery of cancer cells have been co-cultured with calcarea carbonica-primed T cells. Our benefits indicated a “two-step” mechanism of your induction of apoptosis in tumor cells by calcarea carbonica i.e., (1) activation with the immune program in the host; and (two) induction of cancer cell apoptosis via immuno-modulatory circuit in p53dependent manner by down-regulating Bcl-2:Bax ratio. Bax up-regulation resulted in mitochondrial transmembrane possible loss and cytochrome c release followed by activation of caspase cascade. Knocking out of p53 by RNAinterference inhibited calcarea carbonica-induced apoptosis thereby confirming the contribution of p53. Conclusion: These observations delineate the significance of immuno-modulatory circuit during calcarea carbonicamediated tumor apoptosis. The molecular mechanism identified might serve as a platform for involving calcarea carbonica into immunotherapeutic tactics for effective tumor regression.
