While we observed no significant change in growth of HBEC3-KT cells after siRNA depletion of COMMD1 (Figure 4B), in the NSCLC cell lines, there was a significant retardation of cell growth after COMMD1 depletion with siRNA #1 and #2 (Figure 4C–E), suggesting that COMMD1 is required for the proliferation of NSCLC cells. Here, COMMD1 is linked to non-small cell lung carcinoma.
