WebThe mammalian intestinal tract epithelium is renewed every ~4–6 days, which is arguably the most rapidly turned over tissue in the body. Cellular turnover is facilitated by the intestinal epithelium being organized as crypts with highly proliferative stem cells and progenitor/transit-amplifying cells located near the crypt base and quiescent, terminally … WebJun 16, 2016 · During homeostasis, differentiated colonocytes metabolized butyrate likely preventing it from reaching proliferating epithelial stem/progenitor cells within the crypt. …
WebGSDMB is upregulated and most prevalently expressed in intestinal epithelial cells (IECs), specifically colonocytes/crypt top colonocytes from patients with IBD compared with healthy controls. Moreover, GSDMB, independently from its established effect in pyroptosis, regulates IEC proliferation and migration to the mucosa. Webfunction in colorectal mucosa. Normal colonocytes gain 70– 80% of their energy from butyrate (3) and therefore epithelial proliferation is supported (4). Conversely, intestinal tumor cell lines respond to butyrate with growth arrest, differentiation and apoptosis (5–10). In vitro studies demonstrated that butyr-
