Project description:We recently showed HMX is expressed in bipolar tail neurons (BTN) in early embryos of Ciona intestinalis. In order to assess the function of the homeobox transcription factor in this cell fate, we used an overexpression strategy. ciHMX was overexpressed in the epidermis, followed by RNAseq of experimental and control embryos. We then looked for differential expression of BTN fate markers, testing if HMX is able to regulate BTN fate determination.
Project description:The transcriptome of unfertilized eggs of Ciona intestinalis was determined with microarrays. To obtain gene expression profiles of unfertilized eggs, we took 14 biological replicates. For the first through fourth replicates, we also took a technical duplicate. Gene expression profiles of the 8-, 16-, 32-cell embryos were obtained with embryos from the third to fifth animals.
Project description:DNA binding profiles of three maternal factors (Tcf7, Gata.a and Zic-r.a) in chordate 16-cell stage embryo. 16-cell stage ciona intestinalis embryos were collected from multiple batches and the extracted chromatin was immunoprecipitated by the antibodies which specifically recognize ciona Gata.a, Tcf7 and Zic-r.a, respectively.
