From: Quantitative proteomic analysis of sphere-forming stem-like oral cancer cells
Western blot analysis of CREB-1, phospho-CREB1 (p-CREB-1) and CREB-binding protein (CBP) between CSC-like and non-CSC UM1 cells (A). The normalized level of p-CREB-1 or CBP against β-actin is shown in (B) and (C). Both CBP and p-CREB-1 were significantly (P <0.0005, n = 3) over-expressed in CSC-like UM1 cells when compared to non-CSC UM1 cells. CSC, cancer stem cells.
