Banf1 induces aberrant NE morphology in TNBC cells. Representative immunofluorescent microscopy images of MCF10A and TNBC cells transfected with Control and Banf1 siRNAs. Cells were stained with anti-Lamin A/C to visualise the NE. Cells were counterstained with Hoechst 3342 (blue). (a) MCF10A (c) BT549 (e) Hs578T (g) MDA-MB-231 and (i) MDA-MB-468. Quantification of cells with aberrant nuclear morphology in Control and Banf1 transfected cells. Form Factor score of 1 = perfect round nucleus. Quantifications are based on 200 cells/condition per repeat. Error bars denote S.D. Normalised nuclear form factor values for: (b) MCF10A (d) BT549 (f) Hs578T (h) MDA-MB-231 and (j) MDA-MB-468. (k - l) Representative images of immunofluorescence staining of α-tubulin (green) in representative TNBC cell lines 72 h post-transfection with control and Banf1 siRNA. Cells were counterstained with Hoechst 3342 (blue) nuclear staining. (k) MCF10A (l) BT549. Statistical significance was calculated using unpaired t-test: ***, < p 0.0002, *, p < 0.0332 (n=3 for all experiments).
