FIG 4.
PIK3C2A is required in primary infected cells for VLP formation in HT-29 cells. Graphs showing the relative proportion of protrusions (Protrusions) and vacuole-like protrusions (VLP) in mock-treated (Mock) (A), PIK3C2A-depleted (PIK3C2A KD) (B), and PIK3C2A-depleted (C) HT-29 cells transfected with an RNAi-resistant construct (PIK3C2A res). Values represent the mean of 3 independent experiments. Statistical analysis: PIK3C2A KD versus Mock (VLP), P < 0.0001; PIK3C2A KD versus PIK3C2A res (VLP), P < 0.0005; unpaired t test.
