Abstract

Breast cancer chemoprevention has become increasingly important in India as it faces a potential breast cancer epidemic over the next decade. Curcumin, the active ingredient in turmeric is a well known chemopreventive agent that possesses various therapeutic properties including antioxidants and anti-inflammatory effects. In the present study, we have investigated the inhibitory effects of BDMC-A, an analog of curcumin, on invasion, angiogenesis and metastasis markers using in vitro with MCF-7 cells and in silico studies, hence proved that BDMC-A has more potential than curcumin. Mechanistic studies revealed that BDMC-A might have exerted its activity by inhibiting metastatic and angiogenic pathways by modulating the expression of proteins upstream to NF-κB (TGF-β, TNF-α, IL-1β and c-Src), and NF-κB signaling cascade (c-Rel, COX-2, MMP-9, VEGF, IL-8) and by upregulating TIMP-2 levels. An in silico molecular docking study with NF-κB revealed that the docking score and interaction of BDMC-A with NF-κB-DNA binding was more efficient when compared to curcumin. Our overall results showed that BDMC-A more effectively inhibited invasion, angiogenesis and metastasis markers compared to curcumin. The activity can be attributed to the pr...Continue Reading
