Analysis of hnRNP K interacting RNAs in myeloid KG-1a cells

ABSTRACT: HNRNPK is part of the minimally deleted region (MDR) in AML del(9q). To understand the function of hnRNP K in pathogenesis of this AML subtype, we analyzed the function of hnRNP K as an RNA binding protein in myeloid cells. Co-immunoprecipitated RNAs from hnRNP K and non-related control immunoprecipitation as well as input RNA were subjected to next generation sequencing. This analysis revealed an interaction of hnRNP K with 1076 RNAs, among them many mRNAs encoding transcription factors involved in myeloid differentiation and AML pathogenesis.

Genome-wide Genotyping of Acute Myeloid Leukemia with Translocation t(9;11)(p22;q23) Reveals Novel Recurrent Genomic Alterations

Project description:To identify cooperating lesions in de novo and therapy-related acute myeloid leukemia (t-AML) with translocation t(9;11)(p22;q23) we performed high-resolution SNP-array profiling on 40 leukemia samples [de novo: n=22; t-AML: n=16; unknown: n=2]. A mean of 1.73 copy number alterations (CNAs)/case were identified with no differences between de novo and t-AML cases. We identified a novel minimally deleted region (MDR) at 7q36.1-q36.2 partly overlapping with a MDR previously identified in core-binding factor AML; MLL3 was the only gene affected in both regions. In addition, a recurrent gain was found at 13q21.33-q22.1 harboring the potential oncogene KLF5. Sequence/expression analysis of selected candidate genes revealed deregulated EVI1 at high frequency (50%). Copy-neutral loss-of-heterozygosity (CN-LOH) was absent in the paired cohort Further analysis of the candidate genes might provide novel insights into the pathogenesis of t(9;11) AML SNP genotyping was performed on 40 de novo and therapy-related MLL-MLLT3-rearranged acute myeloid leukemia samples; Germline control DNA from remission bone marrow or peripheral blood was available for paired analysis in 15 patients. Data were processed using reference alignment, dChipSNP and circular binary segmentation.

hnRNP A1 iCLIP

Project description:This experiment identifies hnRNP A1 binding sites transcriptome-wide in Hela cells. HeLa cells with inducible expression of T7-tagged hnRNP A1 were grown to approximately 90% confluence and then subject to iCLIP analysis (following the protocol from Huppertz et al. 2014 (iCLIP: protein-RNA interactions at nucleotide resolution)). The iCLIP library was sequenced using Illumina's HighSeq 1500

hnRNP R promotes O-GlcNAcylation of eIF4G to facilitate axonal protein synthesis

Project description:Motoneurons critically depend on precise spatial and temporal control of translation for axon growth and the establishment and maintenance of neuromuscular connections. While defects in local translation have been implicated in the pathogenesis of motoneuron disorders, little is known about mechanisms regulating axonal protein synthesis. Here, we report that motoneurons derived from Hnrnpr knockout mice show reduced axon growth accompanied by lowered synthesis of cytoskeletal and synaptic components in axons. Mutant mice display denervated neuromuscular junctions and impaired motor behavior. In axons, hnRNP R is a component of translation initiation complexes and, through interaction with O-linked β-N-acetylglucosamine (O-GlcNAc) transferase (Ogt), modulates O-GlcNAcylation of eIF4G, thereby stimulating translation. Restoring axonal O-GlcNAc levels rescued local protein synthesis and axon growth defects of hnRNP R knockout motoneurons. Together, these findings demonstrate a function of hnRNP R in controlling the local production of key factors required for axon growth and formation of neuromuscular innervations.

Downstreams of hnRNP A2 in Colo16 cells

Project description:Limited knowledge of the downstream targets of hnRNP A2/B1 has, however, precluded a clear understanding of their roles in cancer cell growth. To define the pathways in which this protein acts we have now carried out microarray experiments with total RNA from Colo16 epithelial cells transfected with an shRNA that markedly suppresses hnRNP A2/B1 expression. The microarray data identified 123 genes, among 22283 human gene probe sets, with altered expression levels in hnRNP A2/B1-depleted cells. Ontological analysis showed that many of these downstream targets are involved in regulation of the cell cycle and cell proliferation and that this group of proteins is significantly over-represented amongst the affected proteins. The changes detected in the microarray experiments were confirmed by real-time PCR for a subset of proliferation-related genes. Immunoprecipitation-RT-PCR demonstrated that hnRNP A2/B1 formed complexes with the transcripts of many of the verified downstream genes, suggesting that hnRNP A2/B1 contributes to the regulation of these genes.

ChIP-Seq hnRNP E1, Cervical cancer SiHa cells

Project description:Based on the specificity with which the unique KH structural domains of hnRNP E1 bind with RNA/DNA, considering that HPV16 provides RNA/DNA binding sites, we hypothesized that hnRNP E1 may be crucial to HPV16 oncogenes expression and cervical carcinogenesis. Based on the main purpose of this study was to explore the role of hnRNP E1 on the regulation of HPV16 oncogene expression in cervical cancerization, we conducted ChIP-seq in the untreated SiHa cell line.
