Transcriptome responses of duodenal epithelial cells to endurance swimming in female rats.

Intestinal calcium absorption is the sole pathway to supply calcium to the body and duodenum is the most efficient site of calcium absorption. Endurance exercise with moderate intensity significantly increased the intestinal calcium absorption. The unloaded non-impact excercise, such as swimming may enhance calcium absorption. However, the cellular and molecular mechanisms of this change have not been investigated. Thus, a genome-wide study by using microarray should reveal changes in the expression of several transporter genes in the intestinal absorptive cells of swimming excercised rats.
