Formalin-fixed paraffin-embedded tissue sections of human stomach were probed for Carbonic Anhydrase IX/CA9 mRNA (ACD RNAScope Probe, catalog # 559348; Fast Red chromogen, ACD catalog # 322750). Adjacent tissue section was processed for immunohistochemistry using Rabbit Polyclonal (Novus catalog # NB100-417) at 1:1000 dilution with overnight incubation at 4 degrees Celsius followed by incubation with anti-rabbit IgG VisUCyte HRP Polymer Antibody (Catalog # VC003) and DAB chromogen (yellow-brown). Tissue was counterstained with hematoxylin (blue). Specific staining was localized to glandular cells.Western Blot Detection of Carbonic Anhydrase IX/CA9 in Multiple Human Cell Lysates

Background: Carbonic Anhydrase IX/CA9
Carbonic anhydrase IX (theoretical molecular weight 50kDa) belongs to the monomeric alpha class and is a single pass-transmembrane protein with two extracellular domains which serve catalytic and cell adhesion functions (2, 3). By cooperating with sodium bicarbonate cotransporters (NBC), lactate and proton exporting monocarboxylic acid transporters (MCT), and a sodium/hydrogen exchanger (NHE), carbonic anhydrase IX is involved in pH regulation across the cell membrane. This functional property protects cancer cells from intracellular acidification and partly explains the role of carbonic anhydrase IX in cancer cell survival and proliferation. In contrast, the pH regulating activity of carbonic anhydrase IX induces extracellular acidification, which has been implicated in epithelial to mesenchymal transition (EMT) and promoting cancer invasion. Carbonic anhydrase IX is frequently overexpressed in cancer cells (e.g., colorectal-, breast-, lung-carcinoma and brain tumors), an effect promoted by hypoxia within the tumor microenvironment (4). An exception are tumors carrying pVHL inactivating mutations, such as clear cell renal cell carcinoma (ccRCC), where HIF-alpha is stabilized due to dysfunctional proteasomal targeting and can induce HRE (Hypoxia Response Element) containing genes even under physiological normoxia (5). Carbonic anhydrase IX may be detected by immunostaining in tumors, which is found in association with necrotic tissue and metastatic cells. Because the expression of carbonic anhydrase IX correlates with both tumor grade and stage, analysis of its expression in tumors serves as a prognostic factor (4, 6).
