dc.description.abstract | Myo-inositol is a major compatible osmolyte accumulated in the hypertonic renal medulla and in Madin-Darby canine kidney (MDCK) cells cultured in hypertonic media. Myo-inositol is taken up by MDCK cells on a Na+-coupled transporter whose activity increases six-fold 24 h after cells are switched to hypertonic medium. To investigate the mechanism of regulation of the cotransporter by hypertonicity, we used the cDNA encoding the canine Na+-myo-inositol cotransporter that we recently cloned to measure the abundance of the mRNA for the cotransporter and its rate of transcription after changes in osmolality. When MDCK cells were switched from isotonic to hypertonic medium, cotransporter mRNA abundance rose 10-fold in 16 h. Transcription of the cotransporter gene also rose and 16 h after the switch reached a peak ∼15-fold that in isotonic cells. When cells were switched back to isotonic medium, mRNA abundance and transcription of the gene returned to isotonic levels in 8 h and transport rate reached isotonic levels in 48 h. Thus transcription appears to be the primary step in regulation of myo-inositol transport by hypertonicity. | - |
