Expression of AQPGs and AQP1 in selected mammalian tissues.

Numbers of EST transcripts were obtained through blast searches of human, mouse, rat, dog and bull EST databanks and are expressed per million transcripts based on the following equation: [number of human, mouse, rat, dog and bull AQP transcripts] ÷ [total number of human, mouse, rat, dog and bull AQP transcripts] × 106. Number of AQP-specific and of total transcripts is probably overestimated given that some sequences may belong to the same EST clone. For certain tissues, data were not available in all species and total number of transcripts was low. Subtissular and subcellular localization were obtained through literature searches. Abbreviations: AP, apical; BL, basolateral; CD, collecting duct; C&S, chondrocytes and synoviocytes; n/a, non-available; OB, osteoblasts; OC, osteoclasts; PT, proximal tubule; RTC, renal tubular cells; SIEC, small intestinal epithelial cells.
