The rapid time course of induction and sensitivity of CaT1 mRNA response to 1,25-dihydroxyvitamin D treatment supports the idea that CaT1 could play a role as a gatekeeper of intestinal calcium absorption.
This regulatory genomic response of the enterocyte would result in an increase in the brush border membrane content of CaT1 calcium influx channels that could function as a gatekeeper mechanism to augment the rate of calcium entry across the apical membrane [ 9 ] . However, given that there is a Ca-dependent negative feedback mechanism to limit calcium entry through the channel by maintaining the channel in the closed position [ 14 15 ] there must be a way to remove calcium from the vicinity of the cytosolic face of the channel to optimize and sustain calcium influx rates.
Enter the AFI--a gatekeeper that, true to its times, has yielded to more commercial concerns.
The Office of Intelligence Policy and Review became the gatekeeper for the flow of FISA information to criminal prosecutors.
Thus, in the current study, to evaluate a possible gatekeeper role for CaT1 in vitamin D-mediated calcium transport we compared the time course of 1,25-dihydroxyvitamin D induction of calbindin D9k mRNA and CaT1 mRNA in Caco-2 cells.
