Project description:Case report on Lamellar ichthyosis with a novel frameshift/truncating NIPAL4 mutation
Project description:The biology of Harlequin Ichthyosis (HI), a devastating skin disorder, caused by loss of function mutations in the gene ABCA12, is poorly understood and to date no satisfactory treatment has been developed. We sought to investigate pathomechanisms of Harlequin Ichthyosis which could lead to the identification of safe and effective treatments to improve patients' quality of life. RNA-Seq analysis using normal skin (n=5) and HI patient skin (n=4) were performed to define the effects of loss of ABCA12. Functional annotation clustering analysis showed changes in three common groups: epidermal differentiation, lipid metabolism and inflammation (innate immunity and IFNγ signalling). In HI patient skin, gene expression of STAT1, STAT3 and Interleukin 36 (IL-36) A and G cytokines was significantly upregulated compared to normal skin, whereas IL-37, an inhibitor of innate immunity, was downregulated. RNA-Seq and functional assays were performed to define the effects of loss of ABCA12, using an engineered CRISPR-Cas9 ABCA12 KO 3D model. Functional annotation clustering analysis showed changes in three common groups: epidermal differentiation, lipid metabolism and inflammation.
Project description:Gene expression analysis of the epidermis from Lexicon Genetics Abca12 knockout mouse model of Harlequin Ichthyosis compared with wild type embryos to search for pathways specifically altered in the condition. Results indicate a large immune and inflammatory response occurs in the sterile environment of the uterus.

Project description:Ichthyosis Curth–Macklin is a rare genetic disorder that is clinically characterized by severe palmoplantar keratoderma. We have described previously a severe familial phenotype caused by a novel mutation in the KRT1 gene. In this study, we analyzed the skin of one patient using gene expression microarrays. We used microarrays to study the differences of gene expression between normal skin and skin affected by Ichthyosis Curth-Macklin
Project description:To understand the effects of Hsp60 deficiency in developing vertebrates, we generated CRISPR/Cas9-mediated hspd1 knockout zebrafish lines by targeting exon 2 to induce a frameshift mutation. We selected an allele with a 56 base pair deletion inducing a frameshift mutation leading to loss of protein functions. We examined the transcriptome changes in zebrafish larvae at 5 dpf .
