Project description:The underlying mechanism for CCO is poorly understood We sought to obtain key players and a potential pathway in disease causation through comparative transcriptome (via RNA-Seq) analyses between cornea with CCO from patient with Fanconi anemia and age-matched normal donor cornea
Project description:We compared the epigenetic status of the mutant and disease-free iPSCs at the whole genome level. Whole epigenome profiling based on trimethylated H3K4 (H3K4me3) showed concordant epigenetic remodeling in the two corrected clones when compared with two mutant iPSC clones. Examination of the trimethylated H3K4 histone modification in Fanconi anemia patient iPSCs before and after gene correction

Project description:Fanconi anemia is a rare inherited hematological disorder which commonly presents with bone marrow failure, developmental abnormalities and susceptibility to cancer with high rates of prevalence in ethnic populations. The objective of this study was to identify potential genes that aid in the progression of the disease or produce its principal symptoms and to hypothesize enabling roles for certain genes that are not part of the central molecular machinery causing the disease. A total of 2 Fanconi anemia samples were collected from patients who displayed characteristic FA features. All of them gave positive results for the DNA breakage test after mitomycin C treatment. Samples were referred by Dr. Sheila Mohan of REFAIN (Registry for Fanconi anemia in India). Whole genome microarray analysis of peripheral blood from 2 patient samples and one normal individual. Sequential analysis of microarray data was carried out using gene ontology and pathway analysis to identify candidate genes.
Project description:Fanconi Anemia (FA) is a recessive disorder associated with genomic instability We generated iPSC from FA patient fibroblasts and further corrected the mutated FANCA gene with a homologous recombination-based approach.
Project description:Time point (H0, H24, H72) expression data from an EBV cell line obtained from a Fanconi Anemia patient (FANCA) transduced with a control shRNA (sh Ctrl) (n=3) or a shRNA targeting p53 (sh p53) (n=3) and treated with a brief MMC pulse.
Project description:Fanconi anemia (FA) is a rare inherited disease complicated by aplastic anemia. There is evidence that hematopoietic stem cells have lost self replicative capacity and undergo apoptosis when exposed to inhibitory cytokines including interferon gamma and tumor necrosis factor-alpha. We used gene expression microarrays to identify transcriptomal differences between bone marrow cells from normal volunteers and from children and adults with Fanconi anemia Experiment Overall Design: Fanconi anemia patients were identified using mitomycin C and/or diepoxybutane chromosomal breakage analysis. Eleven normal volunteers and 21 FA patients were studied. All FA patients with cytogenetic evidence of clonal evolution were excluded. All FA patients with acute leukemia were excluded. RNA was prepared from freshly obtained low density mononuclear cell fractions.
Project description:Fanconi Anemia (FA) is a recessive disorder associated with genomic instability We generated iPSC from FA patient fibroblasts and further corrected the mutated FANCA gene with a homologous recombination-based approach. The NSCs were differentiated from control-iPSCs, FA-iPSCs, and corrected FA-NSCs, and their gene expressions were determined by microarray analysis.
