Project description:Transcriptional profiling of pooled adult kidneys from transgenic zebrafish expressing human KIT-D816V mutant gene versus wild-type zebrafish was performed. The aim of this experiment was to determine the expression and cellular changes caused by expression of KIT-D816V oncogene in the hematopoietic organ in zebrafish. This transgenic zebrafish represents a model of systemic mastocytosis with many features of this disease present in adults

This transgenic zebrafish represents a model of systemic mastocytosis with many features of this disease present in adults Two-condition experiment, Tg(actb2:KIT-D816V) versus wild-type(AB), one replicate of each prepared from 3 adult kidneys of each genotype and a dye-swap hybridization of these RNA samples.
Project description:Transcriptional profiling of 28 hpf zebrafish transgenic expressing human KIT-D816V mutant gene versus wild-type embryos was performed. The aim of this experiment was to determine the expression changes caused by expression of KIT-D816V oncogene. This transgenic zebrafish represents a model of systemic mastocytosis with many features of this disease present in adults, but no very clear phenotypes in embryos. Thus, we attempted to determine if there are certain expression changes, which can be used as molecular features of active KIT expressed in these embryos. Two-condition experiment, Tg(actb2:KIT-D816V) versus wild-type(AB), 4 replicate experiments with a dye-swap each time

Project description:To decipher molecular targets responsible for c-Kit mutant D816V mediated hematopoietic malignancy, we employed whole genome microarray expression profiling as a discovery platform to identify important gene targets downstream of c-Kit mutant D816V expressing cells compared to wild-type c-Kit.
Project description:Cdx2 has been suggested to play an important role in Barrett's esophagus (BE), or intestinal metaplasia (IM) in the esophagus. However, in vivo data have been lacking. The aim of the present study was to investigate whether transgenic overexpression of zCdx1b, the functional equivalent of mammalian Cdx2 in zebrafish, may lead to IM of squamous epithelium in zebrafish A transgenic zebrafish system was developed by expressing zCdx1b gene under the control of zebrafish keratin 5 promoter (zK5p). zCdx1b expression in the esophageal squamous epithelium of transgenic zebrafish was analyzed by in situ hybridization, immunohistochemical staining and RT-PCR. Gene expression in the esophageal squamous epithelium of wild-type and transgenic zebrafish was analyzed by Affymetrix microarray and confirmed by in situ hybridization. The upper digestive tract tissue from 3 adult zebrafish (3 months old) was pooled as one sample. Three zCdx1b transgenic samples were used for microarray, and 2 wild type samples were used for control.

Project description:This dataset consists of single-cell RNA-seq (mcSCRBseq) data of neuromast hair cells from wild type and Emx2 mutant zebrafish larvae. Posterior lateral-line neuromast hair cells were isolated by fluorescence activated cell sorting (FACS) from the dissociated trunks of wild type and Emx2-mutant Tg[myo6b:actb1-EGFP] transgenic zebrafish larvae expressing the green fluorescent protein EGFP in hair cells and unipotent hair-cell progenitors (UHCPs).
