The combined treatment of CD24-targeted lentivirus particles together with INS or INR2 peptides led to pancreatic (Fig. 2C, left, black bars) and lung (Fig. 2C, right, black bars) cancer cell death, as demonstrated by WST-1 (Fig. 2C, left) and MTT (Fig. 2C, right) enzymatic assays. This evidence concerns the gene CD24 and cancer.
