MUC1 and renal cell adenocarcinoma: Considering that a previous study detected mRNA expression both in glomeruli and podocytes of normal tissues, we also exemplified costaining of CRHBP both with the anti-nephrin antibody for detection of glomeruli and/or podocytes [20] as well as the anti-MUC-1 antibody as a marker for distal tubules in seven paraffin sections of cc-RCC independent from the tissue microarray samples [19].
