ABSTRACT: Acute (2 hr) response to rxLeptin injection in preoptic area/hypothalamus/pituitary of early prometamorphic (NF stage 54) Xenopus laevis tadpoles
Project description:Leptin binding to the leptin receptor (LepR) causes rapid signaling to the nucleus. We investigated the early (2 hr) transcriptional response to acute leptin injection (intracerebroventricular) in the preoptic area/hypothalamus/pituitary of Xenopus tadpoles.
Project description:Leptin binding to the leptin receptor (LepR) causes rapid signaling to the nucleus. We investigated the early (2 hr) transcriptional response to acute leptin injectio (intracerebroventricular) in the preoptic area/hypothalamus/pituitary of juvenile Xenopus laevis frogs. Frogs were given i.c.v. injections of 0.6% saline or recombinant X. laevis leptin (rxLeptin; 20 ng/g BW) and 2 hrs later killed and the preoptic area/hypothalamus/pituitary dissected.

Project description:Changes in gene expression in the preoptic area/hypothalamus/thalamus of Xenopus tropicalis tadpoles were analyzed using RNAseq at four stages of metamorphosis.
Project description:Changes in DNA methylation in the preoptic area/hypothalamus/thalamus of Xenopus tropicalis tadpoles were analyzed using Methylated DNA Capture sequencing (MethlCap-seq) at four stages of metamorphosis.
Project description:Association of thyroid hormone receptors (TRs) in chromatin across the genome of neural cells in the preoptic area/hypothalamus/thalamus of metamorphic climax stage Xenopus tropicalis tadpoles, analyzed by chromatin-immunoprecipitation sequencing (ChIP-seq).
Project description:Premetamorphic Xenopus laevis tadpole tail respond to thyroid hormone by resorption. The goal of this experiment is to identify the genes involved in the TH-induced resorption tadpole tail and compare it to TH-induced proliferation and differentiation program in tadpole limb and brain. Xenopus tadpoles (NF54) were treated with 100 nM T3(triioodthyronine) in 0.1 x MMR for another 24h and 48h or without T3 for 48h (control group). NF 61 tadpoles were in 0.1 X MMR till they reached NF stage 62. The tails were dissected after the experiment.

Project description:Xenopus laevis tadpoles display a decreasing capacity to regenerate their limbs following injury according to developmental stage. By comparing the regenerative response during the naturally occurring regeneration-competent, -restricted and -incompetent stages, scRNAseq can reveal cell type changes that are required for successful regeneration.
