Horb M., M. Wlizla, A. Abu-Daya, S. McNamara, D. Gajdasik, et al., 2019. The average length of the neoplasia was 7.3 mm at the large end, 4.1 mm at the small ends, and 3.5 mm in height. Common Names: Dwarf clawed frog, Zaire clawed frog Scientific Names: Hymenochirus, Hymenochirus boettgeri Adult Size: Dwarf clawed frogs reach an adult size of about 1 to 1 1/2 inches long. Most of the frogs were harboring only the black stone-like nodules, although a few frogs were harboring both types of nodules simultaneously (Figure 1A). Xenopus tropicalis was provided by Hiroshima University Amphibian Research Center through National BioResource Project (NBRP) of AMED under Grant Number JP19km0210085. Other water sources can be harmful as well, but dont let this keep yo… It is the only species in the genus Xenopus to have a diploid genome. A microscope using an AxioCam MRc digital camera. It has small flattened head, short rounded snout with upward nostrils and small eyes with round pupils.In a cavity behind the nostrils there are two bags by means of which it can smell the air. Share. The population has since then spread to cover an area of about 4,500km². The average length of the neoplasia was 7.3 mm at the large end, 4.1 mm at the small ends, and 3.5 mm in height. Almost all frogs had a single site of neoplasia; just one frog from the NBH-VI-11 colony had multiple sites of neoplasia. Spontaneously occurring neoplasia in amphibians have been reported, such as in X. laevis, Rana pipiens, and Andria japonicus (McKinnell et al., 1968; Meyer-Rochow et al., 1991; Kawasumi et al., 2012). In contrast to X. laevis, 3.66 % of R. pipiens in the wild heterogeneous populations had renal adenocarcinoma (McKinnell et al., 1968), which was experimentally induced by herpesvirus (Granoff, 1973). Your email address will not be published. Here we presenta draft genome sequence assemblyof X. tropicalis. The western clawed frog Xenopus tropicalis is an important model for vertebrate development that combines experimental advantages of the African clawed frog Xenopus laevis with more tractable genetics. This genome encodes more than 20,000 protein-coding genes, including orthologs of at least 1700 human … The high-quality draft sequence of the genome of X. tropicalis, often called the Western clawed frog, will also aid researchers who now use the frog’s more popular cousin, Xenopus laevis (zen’-uh-pus lay’-uh-vus), to study embryo development and cell biology. Therefore, it will be of interest if the frequency and size of neoplasia vary among the inbred strains on disruption of tumor suppressor genes via genome editing. As a test species, we selected the western clawed frog Silurana tropicalis (also called Xenopus tropicalis, phylogenetically related to the most common experimental anuran species X. laevis) because of its experimental advantages (smaller size, shorter life cycle, and diploid genome) over X. laevis (Mitsui et al., 2006; Kashiwagi et al., 2010). Spontaneous neoplasia in the western clawed frog. Species of frog in the family Pipidae, also known as tropical clawed frog. 19K06672, 17KT0049 to H. Ochi and 19K06689, JP18km0210085 to H. Ogino).

Western Clawed Frogs are available online or from specialty tropical fish keeping shops at reasonable prices when they are about 1 1/2″ in size. Caption. The strongest evidence of negative interactions is for western toads. The African clawed frog (Xenopus laevis, also known as the xenopus, African clawed toad, African claw-toed frog or the platanna) is a species of African aquatic frog of the family Pipidae.Its name is derived from the three short claws on each hind foot, which it uses to tear apart its food. can be asked in the same form using the «Additional Comments» field. These strains are available for international research communities upon request. Populations of African clawed frogs have been reported in Arizona, California, Colorado, Florida, Louisiana, Nevada, New Mexico, North Carolina, Virginia, Wisconsin, and Wyoming. We then measured the neoplasia size (Figure 1E). Required fields are marked *. Fixed neoplasias were frozen in Optimum Cutting Temperature Compound, and cryosectioned with a thickness of 10 μm. Western clawed frog is similar to these species: Hylarana galamensis, Natal dwarf puddle frog, Crowned bullfrog and more. Your email address will not be published. The eyes are bulging and situated high on the head and there is a short tentacle just below each eye. Three of the species grow to about 1 - 2 inches, with the exception of the African clawed frog, which can grow up to 5 inches in size. Cancer Res., 33: 1431-1433. Here we present a draft genome sequence assembly of X. tropicalis . African clawed frogs were released from a breeding facility near the town of Saumur when it closed down in the 1980s. Sections were stained with HE by a standard method. Unreviewed-Annotation score: -Protein predicted i. Involved in the breakdown of MTA, a major by-product of polyamine biosynthesis. When a female African clawed frogs is injected with the urine of a pregnant woman, she begins laying eggs. Blue Western Dwarf Clawed Frog. Hylarana galamensis. Females are larger than males. Topic. Has broad substrate specificity with 6-aminopurine … Each slide was photographed under a Zeiss Axio Vert. Two frogs from the NA-XIV-1 colony had a large neoplasia, over 17 mm at the large end, over 15 mm at the small end, and over 12 mm in height (Figure 1E). tropicalis The Genome of the Western Clawed Frog Xenopus This copy is for your personal, non-commercial use only. McKinnell R. G., B. K. McKinnell, 1968 Seasonal fluctuation of frog renal adenocarcinoma prevalence in natural populations. Send Request. Therefore, it will be of interest if the frequency and size of neoplasia vary among … Responsible for the first step in the methionine salvage pathway after MTA has been generated from S-adenosylmethionine. Jeden Tag werden Tausende neue, hochwertige Bilder hinzugefügt. The western clawed frog is a medium-sized species with a somewhat flattened body and a snout-vent length of 28 to 55 mm (1.1 to 2.2 in), females being larger than males. B. Dohse et al., Biochemistry 34, 11335 (1995). The spontaneously occurring neoplasia in X. tropicalis could provide excellent opportunities to understand how the genetic background of this species influences the neoplasia phenotypes in combination with disruption experiments of tumor suppressor genes. Species similar to or like Western clawed frog. This work was supported by Grants-in-Aid for Scientific Research from the Japan Society for the Promotion of Science (JSPS) and AMED (Grants nos.

Une, 2012 Spontaneous nephroblastoma in a Japanese giant salamander (. Clawed frogs have been documented eating both larval and recent metamorphic western toads (Lenaker, 1972). The eyes are bulging and situated high on the head and there is a short tentacle just below each eye. Any other questions such as shipping costs, lead time, etc. All treatment procedures for X. tropicalis were approved by Yamagata University Animal Research Committee (#310300). Meyer-Rochow V. B., M.

California Blvd. Article was last reviewed on 30th September 2019. 11. Histological analysis of X. tropicalis neoplasia using hematoxylin–eosin (HE) staining showed that melanocytes were enriched in the black stone-like nodules and that a layered structure was present (Figure 1B, white arrow). Wikipedia. Analysis of frogs from seven colonies with different genetic backgrounds and chronological ages (16, 7, 6, or 5 years) identified neoplasias formed in various parts of the body, including the dorsal side, ventral side, dorsal head, dorsally on limbs, and eye (Figure 1D). For HE staining, we used the following reagents: Mayer’s hematoxylin solution and 1% eosin Y solution (FUJIFILM Wako Pure Chemical Corporation, Osaka, Japan), Tissue-Tek optimum cutting temperature compound (Sakura Finetek, Tokyo, Japan). Send Request. Figure 1: African Clawed Frog (right) and Western Clawed Frog (image) University of Tokyo. 28: 440-444. In X. laevis, one of 4,000 frogs (a 2.5–3-year-old female), which were maintained in artificial outdoor ponds, displayed renal adenocarcinoma without other developmental disorders, indicating that the tumor formation was quite rare in X. laevis (Meyer-Rochow et al., 1991).
