Aim: To investigate anticancer activity of the DNA binding domain of SMAR1 (His 5) in vitro and in vivo. Materials & methods: His 5 was conjugated to hydrothermally synthesized carbon nanospheres (CNs). Anticancer activity of CNs-His 5 was evaluated in vitro and in vivo. Results: CNs-His 5 significantly reduced cyclin D1 levels in MDA-MB-231 cells. Tumor bearing Balb/c mice injected with CNs-His 5 showed approximately 62% tumor regression and significantly reduced (18)FDG uptake. Caspases assay and IHC staining confirmed tumor growth inhibition, which could be attributed to apoptotic, antiproliferative and antiangiogenic activities of His 5. Conclusion: DNA binding domain of the SMAR1 protein (His 5) has potent anticancer activity and its CNs mediated delivery could control breast tumor in mice model.
