Molecular Engineering of Novel Polymeric Agents for Targeted Cancer Gene Therapy

Abstract Molecular Engineering of Novel Polymeric Agents for Targeted Cancer Gene Therapy Dana Matthews Cancer gene cell therapy is a strategy that involves the administration of genes for correcting the effect of mutated cancer cells in order to induce tumor cell death. In particular, genes that encode for pro-apoptotic proteins can result in death of tumor cells. Prostate cancer is a very common cancer among males in America, and as highly destructive chemotherapy and radiation are generally the only treatments available once the cancer has metastasized, there is a need for the development of treatments that can specifically target and kill prostate cancer cells, while demonstrating low toxicity to other tissue. This experiment will attempt to create such a treatment through gene therapy techniques. The parallel synthesis and DNA binding affinity assay utilized in these experiments have produced a polymer that surpasses pEI-25, a gene delivery polymer standard, in both transfection efficacy and low cytotoxicity and trafficking of polyplexes in the cell, and finding methods to increase the transfection efficacy and specificity of polyplexes for PC3-PSMA cells.
