In accordance with the qRT-PCR analysis of breast cancer tissues and cell lines (Figure 1B and 1C), we found that TSHZ2 was strongly expressed in the nuclei of normal duct epithelium, as well as myoepithelium of human mammary glands, whereas its expression level was markedly reduced in IDC cells (Figure 6A for representative photos; Table for the statistical analysis; Supplementary Table for the details). Here, TSHZ2 is linked to breast cancer.
