Production of novel theranostic nano-vector based on superparamagnetic iron oxide nanoparticles/miR-497 targeting colorectal cancer.

ABSTRACT: Colorectal cancer (CRC) is a serious public health concern worldwide. Immune checkpoint inhibition medication is likely to remain a crucial part of CRC clinical management. This study aims to create new super paramagnetic iron oxide nano-carrier (SPION) that can effectively transport miRNA to specific CRC cell lines. In addition, evaluate the efficiency of this nano-formulation as a therapeutic candidate for CRC. Bioinformatics tools were used to select a promising tumor suppressor miRNA (mir-497-5p). Green route, using Fusarium oxyporium fungal species, manipulated for the synthesis of SPION@Ag@Cs nanocomposite as a carrier of miR-497-5p. That specifically targets the suppression of PD1/PDL1 and CTLA4pathways for colorectal therapy. UV/visible and FTIR spectroscopy, Zeta potential and MTT
