Leukotriene D4

Leukotriene D4 (LTD4) is a cysteinyl leukotriene. Cysteinyl leukotrienes (CysLTs) are a family of potent inflammatory mediators that appear to contribute to the pathophysiologic features of allergic rhinitis. LTD4 is a pro-inflammatory mediator known to mediate its effects through specific cell-surface receptors belonging to the G-protein-coupled receptor family, namely the high-affinity CysLT1 (cysteinyl leukotriene 1) receptor. LTD4 is present at high levels in many inflammatory conditions, and areas of chronic inflammation have an increased risk for subsequent cancer development. LTD4 is associated with the pathogenesis of several inflammatory disorders, such as asthma and inflammatory bowel disease. Exposure to LTD4 increases survival and proliferation in intestinal epithelial cells. CysLT1 regulator is up-regulated in colon cancer tissue and LTD4 signalling facilitates the survival of cancer cells. LTD4 could reduce apoptosis in non-transformed epithelial cells. LTD4 causes up-regulation of beta-catenin through the CysLT1 receptor, PI3K (phosphoinositide 3-kinase), and GSK-3β (glycogen synthase kinase 3β). LTD4 induces beta-catenin translocation to the nucleus and activation of TCF/LEF family of transcription factors. LTD4 causes accumulation of free beta-catenin in non-transformed intestinal epithelial cells through the CysLT1 receptor, and this accumulation is dependent upon the activation of PI3K as well as GSK-3β inactivation (PMID: 16042577, 12607939). Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent and are able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis through receptor-mediated G-protein linked signaling pathways.

CysLT1 regulator is up-regulated in colon cancer tissue and LTD4 signalling facilitates the survival of cancer cells. LTD4 could reduce apoptosis in non-transformed epithelial cells. LTD4 causes up-regulation of b-catenin through the CysLT1 receptor, PI3K (phosphoinositide 3-kinase) and GSK-3b (glycogen synthase kinase 3b). LTD4 induces b-catenin translocation to the nucleus and activation of TCF/LEF family of transcription factors. LTD4 causes accumulation of free b-catenin in non-transformed intestinal epithelial cells through the CysLT1 receptor, and this accumulation is dependent upon the activation of PI3K as well as GSK-3b inactivation.

APGPR Enterostatin

Enterostatin APGPR (Ala-Pro-Gly-Pro-Arg) is a pentapeptide released from procolipase during fat digestion. In addition to the pancreas, enterostatin-immunoreactive cells are also present in the antrum and proximal small intestine. Enterostatin selectively reduces fat intake, decreases insulin secretion, and also increases energy expenditure by activating brown adipose tissue during high-fat feeding. Enterostatins are pentapeptides derived from the NH2-terminus of procolipase after tryptic cleavage and belong to the family of gut-brain peptides. Enterostatin is generated by the action of trypsin on procolipase in the intestinal lumen. Its structure is highly conserved in evolution, with an amino acid sequence of XPXPR. Three enterostatin sequences, Val-Pro-Asp-Pro-Arg (VPDPR), Val-Pro-Gly-Pro-Arg (VPGPR), and Ala-Pro-Gly-Pro-Arg (APGPR), have been studied extensively and shown to be almost equally effective in their ability to decrease dietary fat preference. Enterostatins are selective inhibitors of appetite, particularly of fat intake. Hyperenterostatinemia in obesity is probably secondary to enterostatin resistance; therefore, the regulatory system is producing more enterostatin to counteract the resistance. This is very similar to hyperinsulinemia and hyperleptinemia in obesity. The diminution in the meal-induced secretion of enterostatin in obesity suggests a delay in the appearance of satiety, leading to increased caloric intake. In rats enterostatin decreases body weight by decreasing fat-calorie intake and increasing the sympathetic firing rate of the nerves in interscapular brown adipose tissue. Enterostatin levels are elevated in the plasma of obese women, and enterostatin secretion is diminished after satiety. Oral administration of enterostatin, however, has no effect on food intake, energy expenditure, or body weight in subjects with a preference for a high-fat diet experiencing a negative energy and fat balance, and the physiology of enterostatin in humans remains to be defined.
