Bioengineered Nanomaterials for siRNA Therapy of Chemoresistant Cancers

Area of Science:

• Oncology
• Gene Therapy
• Nanomedicine

Background:

• Chemoresistance is a major obstacle in cancer treatment.
• RNA interference (RNAi) using small interfering RNA (siRNA) shows promise for sensitizing cancer cells to chemotherapy.
• Intracellular delivery of siRNA is limited by biological barriers.

Purpose of the Study:

• To review the development of nanomaterials for siRNA delivery in cancer therapy.
