| cranial neural crest transplants. | the transplantation of cranial neural crest (cnc) expressing green fluorescent protein (gfp) in xenopus laevis has allowed researchers not only to assess cnc migration in vivo but also to address many other experimental questions. coupled with loss- or gain-of-function experiments, this technique can be used to characterize the function of specific genes during cnc migration and differentiation. although targeted injection can also be used to assess gene function during cnc migration, cnc transp ... | 0 | 29321285 |
| cranial neural crest explants. | the cranial neural crest (cnc) explant assay was originally designed to assess the basic requirements for cnc migration in vitro. this protocol describes the key parameters of cnc explants in xenopus laevis, with a focus on how to extirpate cnc cells and assay their migration in vitro. the protocol can be adapted according to the needs of the experimenter, some examples of which are discussed here. | 0 | 29321283 |
| nucleus assembly and import in xenopus laevis egg extract. | xenopus egg extract represents a powerful cell-free biochemical tool for studying organelle assembly and function. large quantities of cytoplasm can be isolated, and biochemical manipulation of extract composition and cell cycle state is relatively straightforward. in this protocol, we describe the reconstitution of nuclear assembly by adding a chromatin source to interphasic x. laevis egg extract. intact nuclei assemble within 30-45 min of initiating the reaction, followed by nuclear growth. we ... | 0 | 29321282 |
| retinoic acid promotes stem cell differentiation and embryonic development by transcriptionally activating cftr. | retinoic acid (ra) plays a pivotal role in many cellular processes; however, the signaling mechanisms mediating the effect of ra are not fully understood. here, we show that ra transcriptionally upregulates cystic fibrosis transmembrane conductance regulator (cftr) by promoting the direct binding of its receptor rarĪ± to cftr promoter in mouse spermatogonia and embryonic stem (es) cells. the ra/cftr pathway is involved in the differentiation of spermatogonia and organogenesis during the embryo de ... | 0 | 29326073 |
| bisphenol f disrupts thyroid hormone signaling and postembryonic development in xenopus laevis. | the safety of bisphenol a (bpa) alternatives has attracted much attention due to their wide use. in this study, we investigated the effects of bisphenol f (bpf), an alternative to bpa, on thyroid hormone (th) signaling and postembryonic development in vertebrates using t3-induced and spontaneous xenopus metamorphosis as models. we found that in the t3-induced metamorphosis assay, higher concentrations of bpf (100-10000 nm) antagonized t3-induced th-response gene transcription and morphological c ... | 0 | 29323886 |
| autocatalytic microtubule nucleation determines the size and mass of xenopus laevis egg extract spindles. | regulation of size and growth is a fundamental problem in biology. a prominent example is the formation of the mitotic spindle, where protein concentration gradients around chromosomes are thought to regulate spindle growth by controlling microtubule nucleation. previous evidence suggests that microtubules nucleate throughout the spindle structure. however, the mechanisms underlying microtubule nucleation and its spatial regulation are still unclear. here, we developed an assay based on laser ab ... | 0 | 29323637 |
| spemann-mangold grafts. | in 1924, hans spemann and hilde mangold (née pröscholdt) published their famous work describing the transplantation of dorsal blastopore lip of one newt gastrula embryo onto the ventral side of a host embryo at the same stage. they performed these grafts using two newt species with different pigmentation (triturus taeniatus and triturus cristatus) to follow the fate of the grafted tissue. these experiments resulted in the development of conjoined twins attached through their belly. because of th ... | 0 | 29321278 |
| reference gene identification and validation for quantitative real-time pcr studies in developing xenopus laevis. | reference genes are essential for gene expression analysis when using real-time quantitative pcr (rt-qpcr). xenopus laevis is a popular amphibian model for studying vertebrate embryogenesis and development. further, x. laevis is ideal for studying thyroid signaling due to its thyroid dependent metamorphosis, a stage comparable to birth in humans. when using pcr based studies, a primary concern is the choice of reference genes. commonly used references are eef1a1, odc1, rpl8, and actnb, although ... | 0 | 29323148 |
| increased transcript levels and kinetic function of pyruvate kinase during severe dehydration in aestivating african clawed frogs, xenopus laevis. | the african clawed frog, xenopus laevis, can withstand extremely arid conditions through aestivation, resulting in dehydration and urea accumulation. aestivating x. laevis reduce their metabolic rate, and rely on anaerobic glycolysis to meet reduced atp demands. the present study investigated how severe dehydration affected the transcript levels, kinetic profile, and phosphorylation state of the key glycolytic enzyme pyruvate kinase (pk) in the liver and skeletal muscle of x. laevis. compared to ... | 0 | 29331521 |
