developed a PEG modified gold nanoparticle system by conjugating of RGD peptide and c‐myc siRNA on the surface of gold nanoparticles and tested this system on mice bearing CMT/167 lung carcinoma tumors.[167] The authors observed downregulation of the c‐myc oncogene and significant inhibition of lung tumor growth after the treatment with si‐RNA/RGD AuNPs. This evidence concerns the gene MYC and lung carcinoma.
