Expression of Translationally Controlled Tumor Protein in Human Kidney and in Renal Cell Carcinoma

Figure 3

Immunohistochemical evaluation in normal kidney region. At low power, TCTP staining is present in all the structures belonging to the cortical region ((a) haematoxylin and eosin (H&E); (b) TCTP staining; ((a)-(b)) ×50; (b) inset, negative control, ×50); at higher power, weak TCTP expression is observed in glomeruli ((c) H&E; (d) TCTP staining; ((c)-(d)) ×200) and strong positivity is shown by proximal tubules ((e) H&E; (f) TCTP staining; ((e)-(f)) ×200). In the medullary region, TCTP immunoreactivity was very low or absent ((g) H&E; (h) TCTP staining, ×200). TCTP expression is also present in the transitional epithelium of the renal pelvis ((f) inset, TCTP staining, ×200).
