The caudal-related (Cdx) homeodomain transcription factors have a conserved role in the development of posterior structures in both vertebrates and invertebrates. A particularly interesting finding is that Cdx proteins have an important function in the regulation of expression from a subset of Hox genes. In this study, we report the cloning of cDNAs from the Cdx genes of the amphibian Xenopus tropicalis. Xenopus tropicalis is a diploid species, related to the commonly used laboratory animal Xenopus laevis, and has attracted attention recently as a potential genetic model for animal development. The Xenopus tropicalis cDNAs, Xtcad1, Xtcad2, and Xtcad3, show between 88 and 94% sequence identity with their Xenopus laevis orthologues. This finding corresponds to between 90 and 95% identity at the level of derived amino acid sequence. We also present a detailed description of Xtcad1, Xtcad2, and Xtcad3 expression during normal development. In common with the Cdx genes of other vertebrates, the ...

The frog genus Xenopus is widely used as a model system for studying developmental biology and fundamental cell biological processes. The advantages that Xenopus offer as an experimental system include (1) the availability of large abundant eggs that are easily manipulated, (2) ready accessibility to any developmental stage, and (3) conservation of cellular pathways between Xenopus and mammals. Over the past 50 years, pioneering studies on Xenopus have been crucial towards our understanding of nuclear reprogramming, embryonic patterning, membrane channels and receptors, and the cell cycle.. Despite its popularity for biomedical research, genomic resources for Xenopus have been lagging behind other model organisms. A major reason for this is that early developmental and molecular studies have relied on a particular species known as Xenopus laevis, which is pseudotetraploid as a result of genome duplication around 30 million years ago. The presence of four copies of every gene complicates genetic ...
We present a genetic map for Xenopus tropicalis, consisting of 2886 Simple Sequence Length Polymorphism (SSLP) markers. Using a bioinformatics-based strategy, we identified unique SSLPs within the X. tropicalis genome. Scaffolds from X. tropicalis genome assembly 2.0 (JGI) were scanned for Simple Sequence Repeats (SSRs); unique SSRs were then tested for amplification and polymorphisms using DNA from inbred Nigerian and Ivory Coast individuals. Thus identified, the SSLPs were genotyped against a mapping cross panel of DNA samples from 190 F2 individuals. Nearly 4000 SSLPs were genotyped, yielding a 2886-marker genetic map consisting of 10 major linkage groups between 73 and 132cM in length, and 4 smaller linkage groups between 7 and 40cM. The total effective size of the map is 1658cM, and the average intermarker distance for each linkage group ranged from 0.27 to 0.75cM. Fluorescence In Situ Hybridization (FISH) was carried out using probes for genes located on mapped scaffolds to assign linkage ...

In our laboratory, we use Xenopus laevis, commonly known as the African clawed frog (learn more on wikipedia). Xenopus laevis is a great model system for dissecting the molecular pathways in DNA replication and the maintenance of genomic stability. Cell-free extracts made from Xenopus eggs contain all the proteins necessary to undergo 12 rounds of cell-cycle regulated, semi-conservative DNA replication in the absence of transcription. Events in these extracts are highly synchronous, allowing the analysis of short-lived intermediates and the dissection of signal transduction cascades. Particularly, the function of essential proteins can be addressed by immunodepletion or neutralization of these proteins, coupled to rescue with recombinant proteins. Xenopus cell-free extracts are generated by centrifuging unfertilized Xenopus eggs and isolating the cytoplasmic layer. Female Xenopus can be induced to lay an abundance of eggs after hormone injection. In fact, Xenopus laevis were used as a pregnancy ...
Although thoroughly studied in terms of structural, biochemical and biophysical characteristics, the biological functions of avidins are not fully understood. Here, we expand the research on avidins by reporting xenavidin, the first avidin-like protein from a frog, which was identified as an expressed sequence tag (EST) from the Xenopus tropicalis genome project. Avidins appear to be conserved among egg-laying vertebrates [3, 4, 6] and are thought to have a role as defence proteins against microbial infections [43, 44]. Bird eggs contain egg yolk, the compartment for embryonic development, and the egg white that surrounds the egg yolk provides both nutrients and protection for the embryo. In frogs, the equivalent to egg white is called egg jelly [45]. The avidin content of egg jelly may have an important role in the embryonic development of frogs, a hypothesis that is also supported by recent studies within natural bird populations, in which the concentration of avidin in egg white appears to be ...
The community effect is an interaction among a group of many nearby precursor cells, necessary for them to maintain tissue-specific gene expression and differentiate co-ordinately. During Xenopus myogenesis, the muscle precursor cells must be in group contact throughout gastrulation in order to develop into terminally differentiated muscle. The molecular basis of this community interaction has not to date been elucidated. We have developed an assay for testing potential community factors, in which isolated muscle precursor cells are treated with a candidate protein and cultured in dispersion. We have tested a number of candidate factors and we find that only eFGF protein is able to mediate a community effect, stimulating stable muscle-specific gene expression in demonstrably single muscle precursor cells. In contrast, Xwnt8, bFGF, BMP4 and TGF(β)2 do not show this capacity. We show that eFGF is expressed in the muscle precursor cells at the right time to mediate the community effect. Moreover, ...
The amphibian Xenopus has long been a comparative model system of choice for a number of different biological research areas, including immunology. Specifically, the evolutionary distance between amphibians and mammals, including humans, allows for the study of both species-specific adaptations, as well as conserved features of the immune system. Furthermore, the Xenopus genus includes species with multiple levels of polyploidy, thereby providing a unique model to study whole genome duplication and its effects thereof on individual genes. To better exploit this amphibian model, the development and innovative applications of novel research tools have been a priority. In this regard, recent advances in adapting the transgenesis approach to Xenopus have allowed for in vivo studies of the impact of loss and gain of function of specific genes at the level of the whole organism, further enhancing the potential uses of Xenopus as an important biomedical model system. This review highlights some of the major

Signal transduction induced by generations of second messengers from membrane phospholipids is a major regulatory mechanism in the control of cell proliferation. Indeed, oncogenic p21ras alters the intracellular levels of phospholipid metabolites in both mammalian cells and Xenopus oocytes. However, it is still controversial whether this alteration it is biologically significant. We have analyzed the ras-induced signal transduction pathway in Xenopus oocytes and have correlated its mechanism of activation with that of the three most relevant phospholipases (PLs). After microinjection, ras-p21 induces a rapid PLD activation followed by a late PLA2 activation. By contrast, phosphatidylcholine-specific PLC was not activated under similar conditions. When each of these PLs was studied for its ability to activate intracellular signalling kinases, all of them were found to activate maturation-promoting factor efficiently. However, only PLD was able to activate MAP kinase and S6 kinase II, a similar ...
All modes of Xenopus research (embryos, cell-free extracts, and oocytes) are commonly used in direct studies of human disease genes and to study the basic science underlying initiation and progression of cancer.[19] Xenopus embryos for in vivo studies of human disease gene function: Xenopus embryos are large and easily manipulated, and moreover, thousands of embryos can be obtained in a single day. Indeed, Xenopus was the first vertebrate animal for which methods were developed to allow rapid analysis of gene function using misexpression (by mRNA injection [20]). Injection of mRNA in Xenopus that led to the cloning of interferon.[21] Moreover, the use of morpholino-antisense oligonucleotides for gene knockdowns in vertebrate embryos, which is now widely used, was first developed by Janet Heasman using Xenopus.[22] In recent years, these approaches have played in important role in studies of human disease genes. The mechanism of action for several genes mutated in human cystic kidney disorders ...
Membrane potential and resistance were measured in eggs, cleavage stages and blastulae of the South African toad Xenopus laevis, using intracellular microelectrodes.. The membrane potential increased from −6·5 ± 2mV in eggs to −57 ± 8·0mV at the mid-blastula stage.. The input resistance of fertile eggs ranged from 0·5 MΩ to 5·0 MΩ corresponding to a specific resistance of 20-200kΩcm2. During the first two or three division cycles the input resistance usually decreased by a factor of 2-10 and then subsequently rose during the blastula stages from a mean value of 600 ± 100kΩ at stage 5 to 2·0 ± 0·5 MΩ at stage 8.. At all developmental stages examined, point polarization of a surface cell in the embryo by rectangular current pulses of 0·5−6 × 10−8 A produced voltage deflexions in other surface cells. This was seen even when several (7-8) cell junctions intervened between the current passing and voltage recording microelectrodes at distances of more than 1 mm. These ...

Xenopus laevis is an essential model organism in several areas of biology. In addition to the key attributes of these embryos for in vivo imaging, cell-free extracts from Xenopus provide among the most powerful in vitro systems for studies of cell and molecular biology. A complete sequence of the X. laevis genome is an essential resource for accurate identification of peptides for mass-spec analyses, for cloning of an ORFeome, for identifying evolutionarily conserved regulatory regions, and for design of morpholino-oligonucleotides for gene knockdowns. The Wallingford and Marcotte labs have obtained funding from the Texas Institute for Drug and Diagnostic Development (TI3D), in coordination with projects funded by the National Institutes of Health, to begin sequencing of the X. laevis genome. We are primarily working with Scott Hunicke-Smith at the University of Texas Genome Sequencing and Analysis facility, with funding sufficient for ~20x coverage of the X. laevis genome using ABI SOLiD ...

A novel role of TCF family in body axis formation. Revolutionary high impact discoveries are described, elucidating the missing link in the Wnt pathway and protein-TCF combinations with dual functions. By studying the primary axis formation of Xenopus laevis, it was firstly shown that, in combination with beta-catenin, TCF acts as a potent activator of proto-oncogenes. Secondly, it was discovered that in combination with the Groucho family of proteins, TCF acts as suppressor of oncogene transcription. Stronlgy suggesting that TCF controls oncogene transcription in a dual fashion. These discoveries contributed to the origination of a major area of cancer research and opened multiple angles for cancer therapy development ...
