Project description:Tunicate ascidians exhibit metamorphosis that converts tadpole, swimming larva into immotile adult. In ascidian Ciona intestinalis, the mutant tail regression failed (trf) which shows defects in the metamorphosis was previously reported (Nakayama-Ishimura et al., 2009). In the metamorphosis process, trf larvae settle normally with their adhesive papillae, but do not start tail regression, papillae retraction and sensory vesicle retraction, while development of adult organs proceed. To understand the molecular mechanism of the metamorphosis, microarray analysis of trf mutant was performed.
Project description:Proteome analysis of the surface matrix of chitinous barrier membranes of the tunicate Ciona intestinalis Type A, a marine filter-feeding invertebrate chordate. This chitinous membrane separate food microbes from the gut epithelium, as a physical barrier. As controls, we used mucus cords from the esophagus.
Project description:We report the comprehensive sequencing of small RNA libraries created from different developmental stages (larva and gastrula) of the basal chordate, Ciona intestinalis. These libraries were used for the identification of microRNAs in this organism. Sequencing of small RNA libraries from 2 stages of Ciona intestinalis.
Project description:To compare with new Ciona intestinalis microarray NimbleGen 135k, we peformed gene expression analysis of GPL14686. Total RNAs from common samples with a part of NimbleGen's analysis are used for this analysis. Ovary and Neural Complex from adult Ciona intestinalis, duplicate, 2 time points during spawning
