Fig. 5. Whisker-box plots showing colocalisation between HK13-EGFP fluorescence and plectin immunostaining in AK13-1 cells using Pearson's correlation coefficient. For each group, eight typical double-labelled cells were analysed. The top and bottom of each box delineate the upper and lower 25 percentiles, respectively, the center line demarcates the median and the dots depict the minimum and maximum values. UC, untreated interphase cells; OV, cells treated with 5 mM OV for 10 minutes; OVR, cells treated with 5 mM OV for 10 minutes followed by incubation in OV-free medium for additional 50 minutes; MIT, mitotic cells (late prometaphase); OA, cells treated with 0.1 µg/ml okadaic acid for 3 hours.
