Evidence that sterolin-1 and sterolin-2 may heterodimerize has now been presented, based upon in vitro analyses [ 13 ] . However, our preliminary analyses of immunohistochemistry, using an antibody to sterolin-1 suggests that the pattern of expression in the liver and intestine is similar for both SD as well as WKY or SHR rats (Fig.
The GI tract was segregated into stomach, small intestine and colon, and placed into 10% phosphate buffered formalin for fixation.
Low intestinal calcium absorption efficiency in humans is common and contributes to negative calcium balance and bone loss [ 1 ] . Recent epidemiological evidence suggests that low fractional calcium absorption is a significant risk factor for future osteoporotic hip fracture [ 2 ] . The primary homeostatic mechanism for altering calcium absorption in response to low dietary calcium intake and increased calcium requirements during growth is an increase in plasma 1,25-dihydroxyvitamin D, the active hormonal form of vitamin D produced in the kidney [ 3 ] . 1,25-dihydroxyvitamin D is a seco-steroid that acts on gene transcription through a nuclear steroid receptor protein and also may have nongenomic actions mediated by a putative plasma membrane vitamin D receptor [ 4 ] . Changes in vitamin D status primarily alter the rate of Ca absorption in the proximal small intestine.
In the intact intestine, communication between intestinal epithelial cells and resident immune cells may serve to modulate the initial innate immune response mounted by the epithelial cells.
Bile acids are reclaimed from the lumen of the intestine and returned to the liver via portal blood for reuse [ 1 ] . The recovery of bile acids from the intestine is an efficient process that involves both passive transport along the entire axis of the intestine, and active transport in the terminal ileum [ 5 ] . The apical sodium/bile acid co-transporter (asbt) mediates the active uptake of conjugated bile acids in the ileum [ 5 6 ] . In hepatocytes, both sodium-dependent and sodium-independent transport systems on the sinusoidal membranes extract bile acids from portal blood.
