Distinct profiles of expressed sequence tags during intestinal regeneration in the sea cucumber Holothuria glaberrima.
Repair and regeneration are key processes for tissue maintenance, and their disruption may lead to disease states. Little is known about the molecular mechanisms that underline the repair and regeneration of the digestive tract. The sea cucumber Holothuria glaberrima represents an excellent model to dissect and characterize the molecular events during intestinal regeneration. To study the gene ...
متن کاملTemporal and spatial analysis of enteric nervous system regeneration in the sea cucumber Holothuria glaberrima
There is limited information on the regeneration of the enteric nervous system (ENS) following major reconstruction of the digestive tract. We have studied ENS regeneration in the sea cucumber Holothuria glaberrima which undergoes an organogenic process forming a new digestive tract at the tip of the mesentery. Our results show that (1) a degeneration of nerve fibers occurs early in the regener...
متن کاملLPS-Induced Genes in Intestinal Tissue of the Sea Cucumber Holothuria glaberrima
Metazoan immunity is mainly associated with specialized cells that are directly involved with the immune response. Nevertheless, both in vertebrates and invertebrates other organs might respond to immune activation and participate either directly or indirectly in the ongoing immune process. However, most of what is known about invertebrate immunity has been restricted to immune effector cells a...
متن کاملLipopolysaccharides induce intestinal serum amyloid A expression in the sea cucumber Holothuria glaberrima.
We have previously characterized the first invertebrate homolog of serum amyloid A (SAA) proteins in the sea cucumber Holothuria glaberrima, where its expression is associated with intestinal regeneration, suggesting a possible involvement of SAA proteins in intestinal morphogenesis. Here we show that bacterial lipopolysaccharides (LPS) trigger a coelomocyte-mediated immune response in H. glabe...
متن کاملAntioxidant activity of extracts of two species of Sea Cucumber Holothuria parva and Holothuria leucospilota from the Persian Gulf, Iran
Marine animals are among the most important sources of natural products with biological activities because of their secondary metabolites. Many compounds were extracted, purified, identified and studied for their antioxidant, cytotoxic, anti-inflammatory and antibacterial effects from sea cucumber However, very few investigations are available on Persian Gulf sea cucumbers. The antioxidant act...
