TranscriptomicsNatural Variation and Timing of Stress Responses Promote and Predict Heterosis
Hybrid plants and animals grow larger and more vigorously than the parents, a common phenomenon known as hybrid vigor or heterosis. Heterosis often correlates with the genetic distance between hybridizing parents, but the mechanism for this is largely unknown. We found that genetic distance was corr...

TranscriptomicsQuantitative analysis of proliferative and Ras-induced senescent human primary fibroblasts transcriptomes
The goals of this study is to analyse transcriptionnal changes in senescent cells and to compare them with ChIPseq data for several histones marks and proteins of the SUMO machinery mRNA profiling of proliferative versus Ras-induced senescent humain primary fibroblasts 5 days post-infection

GenomicsHigh definition profiling of mammalian DNA methylation by array capture and single molecule bisulfite sequencing
DNA methylation stabilizes developmentally programmed gene expression states. Aberrant methylation is associated with disease progression and is a common feature of cancer genomes. Presently, few methods enable quantitative, large-scale, single-base resolution mapping of DNA methylation states in d...

GenomicsTranscriptional regulation by H3K122 acetylation in the lateral surface of the histone octamer
We characterize the acetylation of H3K122 for the first time. Towards this we mapped the genomic distribution of H3K122Ac, identified the enzyme introducing H3K122Ac, and addressed the functional contribution H3K122Ac to transcription. We found that H3K122Ac is associated with chromatin marks and ge...

TranscriptomicsTargeting the MTOR-AKT pathway in DLBCL
The mTOR (mammalian Target of Rapamycin) pathway is constitutively activated in Diffuse Large B-Cell Lymphoma (DLBCL). mTOR inhibition has been shown to have clinical activity in patients with DLBCL, although overall response rates remain low. We therefore evaluated differences in the transcriptome...

TranscriptomicsSox4 is a key oncogenic target in C/EBP? mutant Acute Myeloid Leukemia
Mutation or epigenetic silencing of the transcription factor C/EBP? is observed in ~10% of patients with acute myeloid leukemia (AML). In both cases, a common global gene expression profile is observed, but down-stream targets relevant for leukemogenesis are not known. Here we identify Sox4 as a dir...

TranscriptomicsHNRNPU RNA targets and DNA methylation changes during neural differentiation
This study investigates the molecular mechanisms by which the DNA/RNA-binding protein HNRNPU regulates gene expression during early human neural development. Pathogenic variants in HNRNPU cause a severe neurodevelopmental disorder, but the underlying mechanisms remain poorly understood. To explore t...

TranscriptomicsSystematic evaluation of variability in simulated ChIP-chip experiments
The most widely-used method for detecting and measuring genome-wide protein-DNA interactions is chromatin immunoprecipitation on tiling microarrays, commonly known as ChIP-chip. Many tiling array platforms, amplification methods, and analysis algorithms exist for ChIP-chip, but a rigorous assessment...

GenomicsNext Generation Sequencing Facilitates Quantitative Analysis of effect of knockdown of GATA2 on AR binding sites
Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare AR binding activity in LNCaP cells with and without knockdown of GATA2. Methods: LNCaP cells between passage number 32-34 were used for assay. Cells are tr...
