High Membranous Expression of Fatty Acid Transport Protein 4 Is Associated with Tumorigenesis and Tumor Progression in Clear Cell Renal Cell Carcinoma

Figure 1

CD36 was weakly positive in the cytoplasm of tubular epithelial cells (a), while tumor cells show strong membranous expression (b). FATP4 was weakly positive in the cytoplasm and cell membrane of renal tubules, relatively prominent at the basal and apical membranes (c). In RCC tumor cells, FATP4 revealed higher membranous expression than that in normal cells (d). ACSL1 showed diffuse cytoplasmic staining in renal tubules (e) and RCC tumor cells (f), while the staining was remarkably reduced in tumor tissues.
