Since LyP-1 is a peptide binding pancreatic cancer cells, Lin et al. synthesized MWCNTs functionalized with LyP-1 residues (LyP-1@f-MWCNTs) and then functionalised further the achieved nanocomposite with MBD1siRNA, achieving a LyP-1@f-MWCNTs/MBD1siRNA complex [57]. This evidence concerns the gene PTPN22 and familial pancreatic carcinoma.
