(Submitter supplied) Although not an affected cell type, skin fibroblasts from individuals with CC-ALD, an early onset X-linked neurological disorder, show defects in very long chain fatty acid (VLCFA) metabolism that provide the basis for clinical diagnostic tests. Skin fibroblasts from CC-ALD patients can be reprogrammed into iPS cells with all the hallmark properties of pluripotency. The iPS cell phenotypes may reflect the tissue-specificity of the lipid metabolic defects found in CC-ALD patients. more...

(Submitter supplied) Skin fibroblasts from individuals with PBD-ZSD, a rare autosomal recessive disorder caused by peroxisome assembly defects, show defects in lipid metabolism that provide the basis for clinical diagnostic tests, but are not among the cell types most affected by disease. To explore phenotypes of more clinically relevant cell types, skin fibroblasts from PBD-ZSD patients and healthy controls were reprogrammed into iPS cells with all the hallmark properties of pluripotency. more...

(Submitter supplied) Orangutans are an endangered species whose natural habitats are restricted to the Southeast Asian islands of Borneo and Sumatra. For potential species conservation and functional genomics studies, we derived induced pluripotent stem cells (iPSCs) from cryopreserved skin fibroblasts obtained from captive orangutans. We report the gene expression profiles of iPSCs and skin fibroblasts derived from orangtuans.

(Submitter supplied) X-linked adrenoleukodystrophy (X-ALD) is an inherited disorder characterized by axonopathy and demyelination in the central nervous system and adrenal insufficiency. Main X-ALD phenotypes are: (i) an adult adrenomyeloneuropathy (AMN) with axonopathy in spinal cords, (ii) cerebral AMN with brain demyelination (cAMN) and (iii) a childhood variant, cALD, characterized by severe cerebral demyelination. Loss of function of the ABCD1 peroxisomal fatty acid transporter and subsequent accumulation of very-long-chain fatty acids (VLCFAs) are the common culprits to all forms of X-ALD, an aberrant microglial activation accounts for the cerebral forms. How same mutation in the ABCD1 gene can lead to clinically very distinct phenotypes and what factors account for the dissimilar clinical outcomes and prognosis of X-ALD variants remain elusive. We wonder whether epigenetics mechanisms could answer the lack of genotype-phenotype correlation. We employed Illumina state of the art technology to analyze the differential methylation of over 485,000 CpG sites throughout the entire human genome and used stringent statistical criteria to define differential methylation patterns between brains of cALD, cAMN and age-matched controls. We identified a common X-ALD methylation signature comprising the hypermethylation in genes harboring the trimethylated histone H3K27me3 mark in their promoters, the hypermethylation for genes driven the oligodendrocyte lineage, and the hypomethylation for immune-associated genes. We also examined the methylated differences between cALD and cAMN resulting with differential immune response pathways and concordance methylation levels with phenotype severity. The detected methylation differences correlated with transcriptional and translational consequences, as supported by Affymetrix expression arrays, quantitative PCR and WB changes. The reliability of these changes was further demonstrated by validating DNA methylation by an independent pyrosequencing assay. From these evidences, we propose the altered transcriptional programs in oligodendrocyte differentiation in X-ALD patients. These observations may provide new therapeutic epigenetic agents.

(Submitter supplied) Background:Port wine birthmark (PWB) is a congenital vascular malformation resulting from developmentally defective endothelial cells (ECs). Developing clinically relevant disease models for PWB studies is currently an unmet need. Objective: Our study aims to generate PWB-derived induced pluripotent stem cells (iPSCs) and iPSC-derived ECs that preserve disease-related phenotypes. Methods: PWB iPSCs were generated by reprogramming lesional dermal fibroblasts and differentiated into ECs. more...

(Submitter supplied) Here, we report the characterization and the comparison of the transcriptomes of BV-2 murine microglial mutant cell lines (CRISPR/Cas9-edited mutations in peroxisomal genes) by RNA-sequencing. Microglia is suspected to play a major role in the neurodegenerative processes observed in peroxisomal leukodystrophies. From CRISPR/Cas9-edited BV-2 microglial cell lines, we aimed at exploring the transcriptomic consequences of a defect of peroxisomal beta-oxidation.
