26560196 High Claudin 8 Contributes to Malignant Proliferation in Osteosarcoma.
26464708 the expression of claudin-5 and claudin-9 was down-regulated while the expression of claudin-8 was up-regulated in cervical carcinoma tissues compared with adjacent non-neoplastic tissues.
23322640 Human Cldn-8 and -14 were shown to convey Clostridium perfringens enterotoxin-mediated cytotoxicity at pathophysiologically relevant concentrations of this toxin, although ~2-to-10-fold less efficiently than Cldn-4.
19302533 the combination of CK7, S100A1 and claudin 8 immunohistochemistry can be useful for classifying tumours of overlapping histology as chromophobe renal cell carcinoma or renal oncocytomas.
19000657 Na(+) absorption is paralleled by claudin-8-mediated sealing of the paracellular barrier to prevent Na(+) back-leakage, supporting steep Na(+) gradients in distal colon.
18799195 claudin-7 and claudin-8 have potential use as immunohistochemical biomarkers in the differential diagnosis of chromophobe renal cell carcinoma and oncocytoma
17047970 Differential expression of genes encoding claudins in colorectal cancer suggests that these tight junction proteins may be associated to and involved in tumorigenesis.
12736707 CLDN8, clustered with CLDN17 at human chromosome 21q22.11, is a four-transmembrane protein with WWCC motif, defined by W-X(17-22)-W-X(2)-C-X(8-10)-C.
