Protein expression of FN receptors in ANBL-6 cells. Protein expression was compared by Western analysis between the WT, N-RAS, and K-RAS cells for (A) CD44 and (B) β1. (C) Flow chart for isotype control, and α4 and α5 integrins in WT, N-RAS, and K-RAS cells. Fluorescent intensity is represented by the x-axis, and the percent of positive cells is indicated at the bottom right corner of each chart.
