DEPDC4 and neoplasm: From the viewpoint of biological fates of Fol-PEG-α-CDE (G4, DSC2.9, DSF2, DSP2)/siRNA complex and Fol-PEG-α-CDE (G3, DSC2.4, DSF4, DEP4)/siRNA complex, the time courses of blood levels of FITC-labeled siRNA, TRITC-labeled Fol-PEG-α-CDE (G4, DSC2.9, DSF2, DSP2) and TRITC-labeled Fol-PEG-α-CDE (G3, DSC2.4, DSF4, DEP4) were determined after intravenous injection of the complexes to BALB/c mice bearing Colon-26 tumor cells (Figure 9).
