There was no association of hBCATc intensity and ER status (p = 0.601) (Fig. 2c) whilst higher hBCATc intensity was present in HER2 receptor-positive tumours (p = 0.062) (Fig. 2d) suggesting an association of hBCATc with the expression of the HER2 receptor. This evidence concerns the gene ESR1 and neoplasm.
