ATTRACTIVE APPROACHES IN siRNA DELIVERY USING POLYMER BIO-BASED CARRIER SYSTEMS

Abstract

Functional characterization of genes can be determined by disruption of gene expression. This provides powerful approach in designing novel treatment strategies. RNA interference (RNAi) is a natural phenomenon that can aid in the study of post-transcriptional regulation of genes. This mechanism can be stimulated via introduction of double stranded RNA (dsRNA) in a cell. Synthetic short/small interfering RNAs (siRNA) can be utilized to trigger down-regulation of desired genes via transfecting into mammalian cells. Recently, utilization of polymeric carriers has been an attractive approach in drug delivery for medical applications. This review article describes the advantages of exploiting polymeric carriers for siRNA delivery, as bio-therapeutics. Here, we report the current developments, safety and delivery of bio-based siRNAs via polymeric carriers. Additionally, cancer genetics and metabolic disorders including obesity and diabetes pertaining to the progress in clinical applications have been
