(G) Representative IF-FISH images showing CENP-C localization on the Y chromosome in cell growing under selective pressure (G418) following a CENP-AOFF/ON cycle. Chromosomes are highlighted by a white dashed contour line. CENP-C was found at the native centromere position (top panel, blue), the Y chromosome fused to another chromosome indicated by the increased size of the chromosome and the absence of Chr-Y painting probe staining (second panel, orange) or CENP-C was found on a different location on the Y chromosome and did not overlap with Cen-Y DNA (lower panels, red). Scale bar, 2 µm. (H) Quantification of indicated events depicted in G. Each dot represents one experiment (>20 spreads for experiment). Error bars represent SEM from 3 independent experiments. Unpaired t-test, *p=0.0137 and 0.039.
