ABSTRACT
Pancreatic cancer is a lethal malignancy which is refractory to most chemotherapy drugs. Recent landmark studies have shed new light on the complex genetic heterogeneity of pancreatic cancer and provide an opportunity to utilize "precision-based medicines" to target genes based on the genetic profile of an individual's tumor to increase the efficiency of chemotherapy and decrease tumor growth and metastases. Gene-silencing drugs in the form of short-interfering RNA (siRNA) have the potential to play an important role in precision medicine for pancreatic cancer by silencing the expression of genes including those considered difficult to inhibit (undruggable) using chemical agents. However, before siRNA can reach its clinical potential a delivery vehicle is needed to carry siRNA across the cell membrane and into the cytoplasm of the cell. Herein, we detail the methods required to use star polymer nanoparticles to deliver siRNA to pancreatic tumors in an orthotopic pancreatic cancer mouse model to silence the expression of an "undruggable" gene (ßIII-tubulin) that regulates pancreatic cancer growth and chemosensitivity.
