Figure 1

Analysis of napsin A mRNA expression in kidney tissues by in situ hybridization. In normal parts of the kidney, proximal convoluted tubules (a), proximal straight tubules and collecting ducts (b) showed napsin A expression. One positive case of renal cell carcinoma, which expressed napsin A mRNA (a grade II tumor), is shown (c). The majority of renal carcinomas studied did not express napsin A mRNA (d).
