Figure 3From: A lactate shuttle system between tumour and stromal cells is associated with poor prognosis in prostate cancer Immunohistochemical staining for MCT1, MCT4, PDK1 and CAIX expression in non-neoplastic tissue (NNT), PIN lesions (PIN), tumour tissue (TT) and the surrounding stroma for each case. Strong expression of MCT4, PDK1 and CAIX in stromal cells is evident, in contrast with MCT1, which is present only in the epithelial cells of the glands.Back to article page
