Project description:Genome duplication has played a pivotal role in the evolution of many eukaryotic lineages, including the vertebrates.The most recent vertebrate genome duplication is that in Xenopus laevis, which resulted from the hybridization of two closely related species about 17 million years ago. Here we generated epigenetic profiles and determined gene expression in X.laevis embryos to study the consequences of this duplication at the level of the genome, the epigenome and gene expression.
Project description:RNA-seq technology was used to identify differentially localized transcripts from Xenopus laevis and Xenopus tropicalis stage VI oocytes. Besides the discovery of a group of novel animally enriched RNAs, this study revealed a surprisingly low conservation of vegetal RNA localization between the two frog species. mRNA profiles of Xenopus laevis and Xenopus tropicalis animal and vegetal oocyte halves were generated by RNA-seq technology. For Xenopus laevis, animal and vegetal oocyte RNA preparations from two different females were generated in duplicates. For Xenopus tropicalis, animal and vegetal oocyte RNA preparations from two different females were analyzed.

Project description:Comprehensive RNA-seq experiments to measure the expression of homoeologs across different tissues, as a part of the Xenopus laevis genome project. This work is funded by Agency Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT; "Genome Science" Grant ID 221S0002). Collect mRNA from whole tissue; two female frogs were used as donors for most tissues (Taira dataset for one frog, Ueno dataset for the other frog); testis samples were collected from two male frogs (sibling of two female donors)
Project description:In this work, we integrate capillary electrophoresis electrospray ionization mass spectrometry, bottom-up proteomics, and single-cell microanalysis to enable the label-free quantification (LFQ) of proteins in single embryonic cells (D11 blastomeres) in the 16-cell frog (Xenopus laevis) embryo. Based on the LFQ data, we find translational differences between the blastomeres even within the same cell type.
