Adenosine (100 microM) caused an increase in the transepithelial potential (3.6 +\/- 0.4 mV) and equivalent short-circuit current (I(sc), 21 +\/- 3 microA\/cm2), a transient depolarization of the apical membrane potential (14 +\/- 2 mV), and a decrease in the apical membrane resistance. The increase in I(sc) was additive to the effect of forskolin or basolateral addition of a maximal concentration of adenosine. Bumetanide, applied after adenosine, caused a further depolarization (7 +\/- 2 mV) concomitant with a decrease in I(sc) (-13 +\/- 2 microA\/cm2) and an increase in the basolateral membrane resistance. Substitution of Cl- with gluconate or Na+ with N-methylglucamine reduced the response to adenosine by &gt;60%. The response was also reduced by a low concentration of amiloride. We conclude that stimulation of the apical adenosine receptor activated a cation conductance in the apical membrane. <\/jats:p>","DOI":"10.1152\/ajpcell.1997.272.3.c931","type":"journal-article","created":{"date-parts":[[2017,12,24]],"date-time":"2017-12-24T16:40:01Z","timestamp":1514133601000},"page":"C931-C936","source":"Crossref","is-referenced-by-count":7,"title":["Apical adenosine activates an amiloride-sensitive conductance in human intestinal cell line HT29cl.19A"],"prefix":"10.1152","volume":"272","author":[{"given":"H.","family":"Bouritius","sequence":"first","affiliation":[{"name":"Graduate School Neurosciences Amsterdam, Biological Faculty, University of Amsterdam, The Netherlands."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
