Researchers at the Agharkar Research Institute (ARI) in Pune have made significant strides in cancer treatment with a new gene-silencing nanomedicine aimed at breast cancer. This innovative platform utilizes biodegradable mesoporous silica nanoparticles to deliver small interfering RNA (siRNA) that targets two critical anti-apoptotic genes, MCL-1 and Survivin, which are known to help cancer cells evade programmed cell death. By modifying the nanoparticles with a protamine biopolymer and a MUC1-specific aptamer, the therapy selectively targets breast cancer cells, thereby enhancing treatment precision and reducing side effects. Experimental results on MCF-7 breast cancer cells and animal studies involving SCID mice indicated substantial tumor growth inhibition and minimal systemic toxicity. The dual gene-silencing mechanism and controlled release of therapeutic agents underscore the potential of this nanomedicine as a safer alternative to traditional chemotherapy. This research may contribute to the development of next-generation precision oncology treatments, as stated by senior scientist Virendra Gajbhiye.
