WebColorectal cancer: The CaSR is expressed in normal human colonic epithelium, mainly in the upper half of the crypt, and is absent from the crypt base . Thus, expression of the CaSR correlates with a [Ca 2+ ] o gradient that, according to Whitfield [ 129 ], decreases in the direction from top to base of the crypt. Webfunction in colorectal mucosa. Normal colonocytes gain 70– 80% of their energy from butyrate (3) and therefore epithelial proliferation is supported (4).
