Expression of CD98hc in normal and TNBC tumoral tissue. A Immunohistochemical stainings of CD98hc showing tumor tissue scored as high (+++), intermediate (++) and low (+), and normal tissue with negative (-) staining. Magnification: 40X. B Immunohistochemical staining of CD98hc in a sample of a patient, showing staining of CD98hc only in tumor tissue and not in normal tissue. Magnification: 20 X. C Box plot showing SLC3A2 gene expression levels in normal and tumor tissue of breast cancer patients. Data were obtained from the TNMplot database. D Box plot showing SLC3A2 gene expression levels in different breast cancer subtypes from patients with breast cancer. The data were obtained using the Xena online tool
