HnRNPK is involved in mRNA processing of a significant fraction of the transcriptome

ABSTRACT: Here, we report the first genomic-scale comprehensive characterization of mouse transcripts bound to hnRNPK. hnRNPK binding at the isoform level was evaluated via RNA-sequencing of liver samples obtained from obese and wild-type mouse models. The comparison of hnRNPK co-immunoprecipitated fractions with total RNA fractions in a given mouse model enabled quantitative evaluation of the binding affinity of hnRNPK for thousands of isoforms.

hnRNPK knock down in Ewing cell line

Project description:Ewing sarcoma is a highly aggressive tumor characterized by a translocation between members of the FET family of RNA binding proteins and one of several ETS transcription factors, with the most common translocation being EWS-FLI1. EWS-FLI1 leads to changes in gene expression through mechanisms that are not completely understood. We performed RNA sequencing analysis on primary pediatric human mesenchymal progenitor cells (pMPCs) expressing EWS-FLI1 in order to identify novel target genes. This analysis identified lnc277 as a previously uncharacterized long non-coding RNA upregulated by EWS-FLI1 in pMPCs. Inhibiting the expression of lnc277 diminished the ability of Ewing sarcoma cell lines to proliferate and form colonies in soft agar whereas inhibiting lnc277 had no effect on other cell types tested. By analyzing gene expression after shRNA knockdown, we found that both EWS-FLI1 and lnc277 repressed many more genes that they induced and that a significant fraction of EWS-FLI1 repressed targets were also repressed by lnc277. Analysis of primary human Ewing sarcoma RNA sequencing data further supports a role for lnc277 in mediating gene repression. We identified hnRNPK as an RNA binding protein that interacts directly with lnc277. We found a significant overlap in the genes repressed by hnRNPK and those repressed by both EWS-FLI1 and lnc277, suggesting that hnRNPK participates in lnc277 mediated gene repression. Thus, lnc277 is a previously uncharacterized long non-coding RNA downstream of EWS-FLI1 that facilitates the development of Ewing sarcoma via the repression of target genes. Our studies identify a novel mechanism of oncogenesis downstream of a chromosomal translocation and underscore the importance of lncRNA-mediated gene repression as a mechanism of EWS-FLI1 transcriptional regulation. A673 Ewing cells expressing an shRNA targeting hnRNPK or control were subjected to paired end RNA sequencing and compared to shGFP control.

Ribosome profiling of Murine Embryonic Fibroblasts in the context of different Fbxo4 and hnRNPK status.

Project description:Background: SCF-Fbxo4 is suspected to regulate activity of RNA binding protein hnRNPK by non-degradive ubiquitylation. Research strategy: To determine the genomic output of SCF-Fbxo4 - hnRNPK interplay, murine embryonic fibroblasts (MEFs) with different status of hnRNPK/Fbxo4 were subjected to Ribosome profiling. Sequencing was performed on total RNA and RNA protected by ribosomes for each condition.

FACS sorting of human adipose tissue stromal vascular fraction

Project description:Adipose tissue from 6 non-obese patients was collagenase treated and adipocytes separated from the stromal vascular fraction(SVF). SVF was then FACS sorted for the following fractions CD45-/CD34+/CD31+ (endothelial), CD45-/CD34+/CD31- (progenitor), CD45+/CD14+ (monocyte/macrophage), CD45+/CD14-(Leukocyte). RNA was isolated from adipocyte, SVF, progenitor, macrophage/monocyte and leukocyte fractions and analyzed on the Affymetrix Human Transcriptome 2.0 array. We also sorted SVF from an additional 13 (10 non-obese, 9 obese) patients and sent progenitor RNA for Affymetrix Human Transcriptome 2.0 array analysis.

4sU-seq analysis for tethering hnRNPK to Xist lacking of XR-PID

Project description:Xist lacking of XR-PID (B-repeat and part of C-repeat) can't recruit the polycomb during X chromsome inactivation. The majoring of Xist-mediated chromosomal silencing wouldn’t be achieved. We found that hnRNPK was the one of main contributors for binding B-repeat of Xist. When we tethered hnRNPK to Xist which lacks of XR-PID region, the silencing and polycomb recruitment are restored.

Regulation of human epidermal progenitor cell function by HNRNPK through transcriptional and post-transcriptional mechanisms

Project description:Maintenance of high-turnover tissues such as the epidermis requires a tight balance between stem and progenitor cell proliferation and differentiation. The molecular mechanisms governing this process are an area of active investigation. Here we show that HNRNPK, a multifunctional protein, is necessary to prevent premature differentiation and sustains the proliferative capacity of epidermal stem and progenitor cells. To prevent premature differentiation of progenitor cells, HNRNPK recruits DDX6 to a subset of mRNAs that code for transcription factors that induce differentiation. Upon binding, these mRNAs such as GRHL3, KLF4, and ZNF750 are degraded which prevents premature differentiation. To sustain the proliferative capacity of the epidermis, HNRNPK recruits RNA polymerase II to genomic sites of proliferation genes such as MYC, FGFBP1, PTHLH, ITGB4 to promote their expressions. Our study establishes a prominent role for HNRNPK in maintaining adult tissue homeostasis through both transcriptional and post-transcriptional mechanisms.
