Figure 6. Cyclin K is required for proliferation of testicular cancer cells.

A) Knockdown of CycK by either scrambled (scr) or two different shRNA constructs (mK-1 and mK-2). Cells were grown for four days after knockdown, and collected for protein blot analyses. B) Crystal violet staining of cells four days after knockdown. C) Quantitation of cells in B) from three independent experiments. Error bars represent SD. Scale bar: 500 µm.
