Figure 2From: Ku proteins interact with activator protein-2 transcription factors and contribute to ERBB2overexpression in breast cancer cell linesKu70 and Ku80 protein levels in cytoplasm and nuclei of cancerous cell lines. 60 μg of nuclear and cytoplasmic proteins extracted from the cell lines were resolved by 10% PAGE. The Ku80, Ku70, AP-2α, AP-2γ and p185erbB2 proteins were revealed by immunoblotting. The antibodies are indicated on left. Beta-actin (β-actin) protein was used as a loading control.Back to article page
