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 (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.
Project description:Fibroblasts from a Fanconi anemia (FA) patient (FA-52) before and after correction by gene editing and transduction with a lentiviral vector expressing telomerase (geFA-52T fibroblasts). IPCs were generated from fibroblasts corrected by gene editing using STEMCCA LV (geFA-52T IPSCs clone 16) and finally the reprogramming cassette was excised (excised geFA-52T IPSCs clone 16.1)

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.
