Article Title: Nuclear Transport Factor 2 (NTF2) suppresses WM983B metastatic melanoma by modifying cell migration, metastasis, and gene expression

doi: 10.1038/s41598-021-02803-0

Figure Lengend Snippet: NTF2 affects lamin A nuclear localization, nuclear size, and heterochromatin distribution. VGP primary melanoma refers to a primary vertical growth phase melanoma cell line (WM983A) that was derived from the same patient as NTF2 low (WM983B) and represents an earlier stage of disease. (A) The indicated cells were stained for lamin A and representative images are shown. Images were acquired with the same exposure time and brightness/contrast were identically adjusted. Line scans were acquired across the nuclear rim as indicated by the yellow line. In the top graph, lamin A intensity was quantified across at least 50 line scans per cell line for two independent experiments (see “ ”). To measure the lamin A intensity at the nuclear envelope (NE), the highest lamin A intensities from each line scan were averaged. To measure the total nuclear lamin A intensity, the total fluorescence intensity of thresholded nuclei was quantified for at least 102 nuclei per condition. To measure the NE/nucleoplasm lamin A intensity, the maximum value along the line scan was divided by the minimum value within the nucleus. Error bars are SD. One-way ANOVA followed by Dunnett’s multiple comparisons test with ***p < 0.0001 and ns not significant. We also measured a 44% reduction in lamin B1 staining intensity at the NE in NTF2 high dox + cells compared to NTF2 low cells (data not shown). (B) Nuclear cross-sectional area, which serves as a good proxy for nuclear surface area and volume , , , , was measured for at least 274 Hoechst-stained nuclei per cell line (918 nuclei on average). The normal melanocyte cell line is AG21857. Error bars are SD. One-way ANOVA followed by Dunnett’s multiple comparisons test with ***p < 0.0001. (C) The indicated cells were stained for the heterochromatin marker H3K9me3 and representative images are shown. Images were acquired with the same exposure time and brightness/contrast were identically adjusted. To quantify heterochromatin distribution, H3K9me3 intensity was quantified along line scans drawn from the nuclear rim toward the center (see “ ”). Averages from at least 150 line scans are shown for each cell line for two independent experiments. Error bars are SEM. One-way ANOVA followed by Dunnett’s multiple comparisons test with **p < 0.01, ***p < 0.0001. The statistical comparisons are for NTF2 low and VGP primary melanoma compared to NTF2 high dox + at line scan position 0.2 µm.
