Fig. 1: ERO1A expression in aggressive human breast cancer.

A A tissue microarray TMA containing breast cancer samples, of which 48 were classified as Luminal A and 52 TNBC, was subjected to immunofluorescence with ERO1A (henceforth, ERO1); nuclei were stained with DAPI. B The same TMA was also subjected to immunofluorescence with Ki67. C Representative zoomed images of ERO1 and Ki67 staining in the indicated Luminal A and TNBC samples. D Dot plots representing the quantification of ERO1 and Ki67 staining (unpaired t-test). E Correlation plot between ERO1 and Ki67, the coefficient of correlation r and the p values were indicated on the graph.
