To identify NEDD9 function in cervical cancer cells, we knocked down NEDD9 in SiHa and HeLa cells using a specific siRNA (S: 5' GAG ACA CCA UCU ACC AAG U[dT] [dT] 3', AS: 5' ACU UGG UAG AUG GUG UCU C[dT] [dT] 3'), which was selected from three candidates by qPCR. This evidence concerns the gene NEDD9 and cervical cancer.
