Cx43 gene regulation in MDA-MB-231 cells affects cell size and
morphology. (a) Representative images of parental MDA-MB-231 (WT),
shCx43, and Cx43D cells. Cell morphology and size are shown in the
bright microscopy panel. The quality of transfected and transduced
MDA-MB-231 cells with shCx43/Cx43D vectors, respectively, is represented
in the GFP/Dendra panel. Scale bar: 50 μm. The bottom panel
represents three-dimensional (3D) reconstructed holographic images
of the different cell subtypes. (b) Cross-sectional height cell measurements
of MDA-MB-231 WT, shCx43, and Cx43D cells, as depicted by the DHM.
(c) Average cross-sectional cell height from at least 30 single cells
in each Cx43 expression condition. The values depicted are the mean
± standard error of the mean (SEM) from three separate experiments,
and at least 30 cells were evaluated per condition. *** denotes a p-value <0.001, ** denotes a p-value
<0.01, and * denotes a p-value <0.05 compared
to different conditions using analysis of variance (ANOVA) followed
by the post hoc Tukey honestly significant difference (HSD) test.
