Scientists from Agharkar Research Institute (ARI), Pune developed an innovative biodegradable nanocarrier platform for targeted gene therapy in breast cancer
ARI is an autonomous institute under the Department of Science and Technology (DST), Government of India
The research was published in Advanced Healthcare Materials journal
The system uses biodegradable mesoporous silica nanoparticles with high loading capacity and tunable surface chemistry
Nanocarrier functionalized with protamine biopolymer and MUC1-specific aptamer for precise tumor targeting
Targets MUC1 receptors overexpressed on breast cancer cells
Uses dual gene-silencing approach delivering siRNAs against two anti-apoptotic genes: MCL-1 and Survivin
Glutathione-responsive design triggers controlled release of therapeutic payload in tumor microenvironment
Biological evaluations conducted in MCF-7 breast cancer models
In vivo studies conducted in Severe Combined Immunodeficiency (SCID) mice
