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.

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 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

Project description:The Fanconi Anaemia (FA) pathway resolves replication fork-stalling inter-strand crosslinks (ICLs) and is mutated in Fanconi anaemia. FA is a rare recessive chromosomal instability syndrome, resulting in hypersensitivity to DNA-crosslinkers, and particularly disadvantageous for stem cell growth and maintenance. FA individuals have an increased risk to haematological malignancies (AML) and head-and-neck squamous cell carcinomas (HNSCC), often very aggressive. Systemic intolerance due to somatic cell hypersensitivity to standard chemo-radio-therapy in patients limits treatment options in FA-HNSCC underscoring an urgent, unmet need to develop novel therapeutic strategies. Here, we performed unbiased functional genomic siRNA screens to unveil genetic interactions that are synthetic lethal with FA pathway deficiency, in a panel of patient-derived, FA-core-complex mutated HNSCC cell lines. We identified RBBP9, LAMTOR2, PSMB2 and PSMC1, among others, as potential FA-HNSCC-specific hits. We demonstrate that RBBP9, a poorly characterized serine hydrolase is synthetically lethal in FA-defective HNSCC and crucial for FA-HNSCC survival. RBBP9 interaction partners are identified in a RBBP9-FLAG IP-MS experiment.

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:To elucidate the transcriptional and epigenetic alterations underlying the neurogenic defects of FA-NSCs, we conducted gene expression microarray analysis and global DNA methylation profiling. The gene expression pattern of gene-corrected NSCs (C-FA-NSCs) resembled that of control-NSCs but clustered distantly from FA-NSCs (Fig. 6F and Table S1). Hierarchical clustering based on DNA methylation levels in the promoter region (+/-1.5kb from TSS) of genes whose expression levels were rescued in C-FA-NSCs, placed C-FA-NSCs closer to control-NSCs and away from FA-NSCs (Fig. 6G), although this pattern was not seen at the whole genome level (Fig. S4C). This suggests that FANCA gene correction leads to specific methylation changes in a subset of promoters. Examination of the methylomes of NSCs derived from Fanconi Anemia iPSCs before and after gene correction by targeted bisulfite sequencing with padlock probes
