Transfection of short-hairpin RNA targeted to retinoblastoma gene effectively diminishes expression of the retinoblastoma (RB) tumor suppressor (immunoblot analysis). β-Tubulin serves as a protein loading control. (MSCV = NCI H520 pMSCVpuro; Rb3C = NCI H520 pMSCVpuro-Rb3C).

Downregulation of retinoblastoma (RB) by means of small interfering RNA results in increased expression of retinoblastoma target genes (immunoblot analysis). (CDK2 = cyclin-dependent kinase 2; PCNA = proliferating-cell nuclear antigen; MSCV = NCI H520 pMSCVpuro; Rb3C = NCI H520 pMSCVpuro-Rb3C; TopoIIα = topoisomerase II alpha; TS = thymidylate synthase).

Inhibition of retinoblastoma activity by small inhibitory RNA increases in vitro growth rates in non–small cell lung cancer cells. NCI H520 cells harboring the retinoblastoma short-hairpin RNA (Rb3C), or the empty vector control (MSCV), were counted every 48 hours. The relative cell count is in comparison to the cell number at day 0. Error bars represent one standard deviation.

5. Fig 4
Non–small cell lung cancer xenografts with reduced retinoblastoma expression by small interfering RNA (Rb3C) exhibit increased growth in nude mice, compared with the empty vector control (MSCV). Tumor volumes were calculated once the tumor was measurable. Error bars represent one standard deviation.
