Project description:The goals of this study are to compare the differentially expressed genes between wildtype and sox3-/- zebrafish ovaries based on RNA-seq data and some of these genes were validated by qRT–PCR. Further, the differentially expressed genes were devided into up-regulated and down-regulated genes for GO and KEGG analysis.
Project description:Zebrafish wildtype adult brain and rb1-embryonal brain tumor transcriptomes were used to identify candidate rb1-interacting chromatin remodelers and epigenetic regulators altered in rb1- transformed brain tumor cells. The data was also used for comparative analysis with zebrafish rb1-/- mutant transcriptome, to identify molecular pathways that distinguish transformed rb1- tumor cells from non-transformed rb1-/- mutant cells.
Project description:The pdx1 knockout zebrafish mutant has been established as an animal model of diabetic retinopathy. Due to a disturbed beta cell development these mutants develop hyperglycaemia leading to an activation of angiogenesis in the retina of larval and adult stages. This study addresses the questions if the pdx1 heterozygous mutant kidney is also affected by similar changes of the microvasculature and if the expression patterns of signaling pathways and mechanisms associated with the development of diabetic conditions are changed in these kidneys. For this purpose we performed RNA sequencing with the mRNA of total adult kidneys of heterozygous pdx1 mutants and their wildtype littermates.

Project description:Single cell RNA-seq (scRNA-seq) from Trim28 ovary knockout and wildtype mice ovaries and testis to help elucidate the function of Trim28 in the adult mouse ovaries. The analysis revealed that loss of Trim28 in the adult mouse ovaries lead to a transcriptional repogramming of the Granulosa cells towards the Sertoli cell fate. Therefore, Trim28 has a function to maintain the adult ovarian cell identity
Project description:Acute exposure to acrylamide (ACR), a type-2 alkene, may lead to a ataxia, skeletal muscles weakness and numbness of the extremities in exposed human and laboratory animals. Recently, a zebrafish model for ACR neurotoxicity mimicking most of the pathophysiological processes described in mammalian models, was generated in 8 days post-fertilization larvae. In order to better understand the predictive value of the zebrafish larvae model of acute ACR neurotoxicity, in the present manuscript the ACR acute neurotoxicity has been characterized in the brain of adult zebrafish, and the results compared with those obtained with the whole-larvae. Although qualitative and quantitative analysis of the data shows important differences in the ACR effects between the adult brain and the whole-larvae, the overall effects of ACR in adult zebrafish, including a significant decrease in locomotor activity, altered expression of transcriptional markers of proteins involved in synaptic vesicle cycle, presence of ACR-adducts on cysteine residues of some synaptic proteins, and changes in the profile of some neurotransmitter systems, are similar to those described in the larvae. Thus, these results support the suitability of the zebrafish ACR acute neurotoxicity recently developed in larvae for screening of molecules with therapeutic value to treat this toxic neuropathy.
