Signal Transduction Pathways for Leptin
Leptin is a critical regulator of energy balance in mammals and has served as a launch point for innumerable studies examining the regulation of food intake and energy expenditure (1). At high physiological concentrations, leptin causes a decrease in food intake, an increase in energy expenditure, and a shift to increased fatty acid oxidation. These physiological shifts lead to a decrease in bo...
متن کاملEngineering Signal Transduction Pathways
Cells respond to their environment by sensing signals and translating them into changes in gene expression. In recent years, synthetic networks have been designed in both prokaryotic and eukaryotic systems to create new functionalities and for specific applications. In this review, we discuss the challenges associated with engineering signal transduction pathways. Furthermore, we address advant...
متن کاملGenistein inhibits tumor invasion by suppressing multiple signal transduction pathways in human hepatocellular carcinoma cells
BACKGROUND Genistein (Gen) exhibits anti-mutagenic and anti-metastatic activities in hepatoma cell lines. Gen has suppressive effects on tumor growth and angiogenesis in nude mice. Gen suppresses the enzymatic activity of matrix metalloproteinase (MMP)-9; however, the mechanism underlying its anti-invasive activity on hepatocellular carcinoma (HCC) cells is unclear. METHODS In this study, the...
متن کاملPterostilbene inhibited tumor invasion via suppressing multiple signal transduction pathways in human hepatocellular carcinoma cells.
Pterostilbene, a natural dimethylated analog of resveratrol, is known to have diverse pharmacologic activities including anticancer, anti-inflammation, antioxidant, apoptosis, anti-proliferation and analgesic potential. However, the effects of pterostilbene in preventing invasion of cancer cells have not been studied. Here, we report our finding that pterostilbene significantly suppressed 12-O-...
متن کاملMammalian bombesin receptors are coupled to multiple signal transduction pathways in pancreatic acini.
We investigated the structural requirements for bombesin (BB)-like peptides to stimulate amylase secretion in rat pancreatic acini and examined the responsible intracellular signal transduction pathways. The tetradecapeptide BB-(1-14) was a full agonist, whereas the heptapeptide BB-(8-14) did not evoke amylase secretion. The mammalian BB analog neuromedin C decapeptide [NMC-(5-14)] was as poten...
