The study emphasized on the development of an efficient, receptor-targeted non-viral gene delivery vehicle for gene therapy of triple negative breast cancer (TNBC). Here, naturally abundant guar gum based non-viral carrier was developed through conjugating by low molecular weight polyethylenimine (LPEI) (GNP) using napthalic anhydride coupling agent and characterized them by FT-IR, H-1 NMR, XRD and UV spectrophotometer. The carrier was found to be cytocompatible as revealed by MTT assay against MDA-MB-231 and HeLa cell lines and excellent blood compatibility till the concentration of 200 mu g/ml. In addition to these, the carrier exhibited excellent gene binding capability and formed spherical shaped complexes. The carrier showed very high in vitro transfection efficiency in TNBC cell (MDA-MB-231) compared to lipofectamine 2000 (LF2k) which could be justified by its high buffering capacity. Therefore, GNP may be an attractive non-viral gene carrier for gene therapy of TNBC in future. (C) 2020 Elsevier B.V. All rights reserved.
