Moreover, using the DNA nanoprism with three aptamer and 3 Rab26 siRNA molecules, the authors demonstrated, by RTqPCR and MTT assay, the downregulation of Rab26 mRNA expression and the decrease of cell proliferation on two NSCLC cell lines (A549 and H1299) [80]. The gene discussed is RAB26; the disease is non-small cell lung carcinoma.
