Flow cytometric analysis of surface integrins in SNX17-depleted HeLa cells. The histograms show levels of indicated integrins in control (red) and SNX17-depleted cells (blue) including an isotype control (gray). The graph represents the mean fluorescence in at least three independent experiments in the percentage of control levels. The dotted line represents the control level, set to 100% for each integrin. The error bars represent the standard deviation. *, P < 0.05.
