S. Huber et al., CHLORIDE CHANNELS CLC-2 AND ICLN MESSENGER-RNA EXPRESSION DIFFERS IN RENAL EPITHELIAL ONTOGENY, Kidney international, 54, 1998, pp. 149-151
Development-dependent mRNA expression of the chloride channels ClC-2 a
nd ICln was studied by quantitative reverse transcriptase-polymerase c
hain reaction in rat ureteric bud and cortical collecting duct primary
monolayer cultures. Abundance of ClC-2 mRNA increased in ureteric bud
cells between embryonic day 15 (E15) and E17, peaked at postnatal day
3 (P3), and was down-regulated at P7 when morphogenesis is complete,
suggesting a specific embryonic function. Expression of ICln mRNA, in
contrast, up-regulated continuously with development.
