Amino/Amido Conjugates Form to Nanoscale Cobalt Physiometacomposite (PMC) Materials Functionally Delivering Nucleic Acid Therapeutic to Nucleus Enhancing Anticancer Activity via Ras-Targeted Protein Interference
Abstract
Aberrant splicing and protein interaction of Ras binding domain (RBD) are associated with melanoma drug resistance. Here, cobalt or nickel doped zinc oxide (ZnO) physiometacomposite (PMC) materials bind to RNA and peptide shown by Ninhydrin staining, UV-vis, Fourier transform infrared, and circular dichroism spectroscopy. PMCs deliver splice switching oligomer (SSO) into melanoma cells or 3-D tumor spheroids shown by flow cytometry, fluorescence microscopy, and bioluminescence. Stability in serum, liver, or tumor homogenate up to 48 h and B16F10 melanoma inhibition ≥98-99% is shown. These data suggest preclinical potential of PMC for delivery of SSO, RBD, or other nucleic acid therapeutic and anticancer peptides.
