Abstract

Effects of intraluminal pressure on cultured intestinal epithelial cells were assessed by measuring cell proliferation and DNA synthesis after exposure to various pressures. Pressures of 40 to 120 mm Hg promoted cell proliferation and DNA synthesis. Pressure-induced DNA synthesis was further enhanced by the addition of interleukin-2, suggesting the regulation of intestinal epithelial growth by pressure in coordination with cytokines. Pretreatment with either a phospholipase C inhibitor or protein kinase C inhibitor significantly inhibited DNA synthesis promoted by pressure and interleukin-2. This study demonstrates a novel mechanism whereby pressure regulates cell growth in intestinal epithelial cells, possibly via activation of phospholipase C and protein kinase C.
