| isolation and cdna cloning of cholecystokinin from the skin of rana nigrovittata. | many neuroendocrine peptides that are distributed in amphibian gastrointestinal tract and central nervous system are also found in amphibian skins, and these peptides are classified into skin-gut-brain triangle peptides, such as bombesins, gastrin-releasing peptides. cholecystokinins (ccks) are neuroendocrine peptides known for their production in the gastrointestinal tract and central nervous system of mammalians. several ccks have been identified from two amphibians, rana catesbeiana and xenop ... | 2007 | 17698250 |
| two novel antimicrobial peptides from skin secretions of the frog, rana nigrovittata. | two novel antimicrobial peptides with similarity to brevinin-2 family are purified and characterized from the skin secretions of the frog, rana nigrovittata. their amino acid sequences were determined as gafgnflkgvakkaglkilsiaqcklsgtc (brevinin-2-rn1) and gafgnflkgvakkaglkilsiaqcklfgtc (brevinin-2-rn2), respectively, by edman degradation. different from brevinin-2, which is composed of 33 amino acid residues (aa), both brevinin-2-rn1 and -rn2 contain 30 aa. five cdna sequences (genbank accession ... | 2011 | 21171145 |
| bi-functional peptides with both trypsin-inhibitory and antimicrobial activities are frequent defensive molecules in ranidae amphibian skins. | amphibian skins act as the first line against noxious aggression by microorganisms, parasites, and predators. anti-microorganism activity is an important task of amphibian skins. a large amount of gene-encoded antimicrobial peptides (amps) has been identified from amphibian skins. only a few of small protease inhibitors have been found in amphibian skins. from skin secretions of 5 species (odorrana livida, hylarana nigrovittata, limnonectes kuhlii, odorrana grahami, and amolops loloensis) of ran ... | 2012 | 21927839 |
| peptidomics and genomics analysis of novel antimicrobial peptides from the frog, rana nigrovittata. | much attention has been paid on amphibian peptides for their wide-ranging pharmacological properties, clinical potential, and gene-encoded origin. more than 300 antimicrobial peptides (amps) from amphibians have been studied. peptidomics and genomics analysis combined with functional test including microorganism killing, histamine-releasing, and mast cell degranulation was used to investigate antimicrobial peptide diversity. thirty-four novel amps from skin secretions of rana nigrovittata were i ... | 2010 | 19778602 |
| a novel bradykinin-like peptide from skin secretions of the frog, rana nigrovittata. | a bradykinin-like peptide has been isolated from the skin secretions of the frog rana nigrovittata. this peptide was named ranakinin-n. its primary structure, raeavppgftpfr, was determined by edman degradation and mass spectrometry. it is structurally related to bradykinin-like peptides identified from skin secretions of other amphibians. ranakinin-n is composed of 13 amino acid residues and is related to the bradykinin identified from the skin secretions of odorrana schmackeri, which is compose ... | 2008 | 17994619 |
| hidden species diversity in sylvirana nigrovittata (amphibia: ranidae) highlights the importance of taxonomic revisions in biodiversity conservation. | accurately delimiting species and their geographic ranges is imperative for conservation, especially in areas experiencing rapid habitat loss. southeast asia currently has one of the highest rates of deforestation in the world, is home to multiple biodiversity hotspots, and the majority of its countries have developing economies with limited resources for biodiversity conservation. thus, accurately delimiting species and their ranges is particularly important in this region. we examined genetic ... | 2018 | 29538432 |
