Values above zero reflect a bias towards inwards fluctuations. C) Representative frames from movies of cells expressing cyclin B1-Venus/H2B-RFP treated with DMSO (top panel), ICRF-193 (middle panel) or VPA (bottom panel).

Time zero corresponds to the moment when compression was applied to the nucleus. C) Ratio between the intensity of dynein on the NE and cytoplasm for control prophase cells (n=12).
