Differential RNA Interactions with Heterogeneous Nuclear Ribonucleoproteins During Vesicular Stomatitis Virus Infection

ABSTRACT: Heterogeneous nuclear ribonucleoproteins (hnRNPs) are involved in many processes in RNA metabolism. In addition to their functions in the nucleus, hnRNPs can function in the replication of RNA viruses in the cytoplasm. In vesicular stomatitis virus (VSV)-infected cells, several hnRNPs relocalize from the nucleus to the cytoplasm. This raises the question of whether these hnRNPs are relocalized together with their host nuclear RNAs or whether they associate with new RNAs in the cytoplasm. hnRNP A1, hnRNP C1/C2, and hnRNP K were immunoprecipitated from mock- or VSV-infected cells, and RNAs were analyzed by high content RNA sequencing. Each hnRNP displayed a loss of interaction with cellular transcripts in favor of viral mRNAs. hnRNP A1 was preferentially associated with VSV phosphoprotein (P) mRNA; hnRNP C1/C2 was preferentially associated with VSV glycoprotein (G) mRNA, and hnRNP K bound viral transcripts in rank of abundance.

Collaborative interactions of heterogenous ribonucleoproteins contribute to transcriptional regulation of sterol metabolism

Project description:Heterogeneous nuclear ribonucleoproteins (hnRNPs) are a group of functionally versatile proteins that play critical roles in the biogenesis, cellular localization and transport of RNA. Although several lines of evidence link hnRNP abnormalities to neurodegenerative diseases and cancer their contribution to metabolic control remains unexplored. Here, we outline a role for hnRNPs in regulatory circuits controlling sterol homoeostasis. Specifically, we find that tissue-selective loss of the conserved hnRNP RALY enriches for metabolic pathways arguing that hnRNPs can discriminately influence regulated gene expression programs. Liver-specific deletion of RALY alters hepatic lipid content and serum cholesterol level. In vivo interrogation of chromatin architecture and genome-wide RALY binding pattern reveal insights into its cooperative interactions and mode of action in regulating cholesterogenesis. Interestingly, we find that RALY binds the promoter region of the master metabolic regulator Srebp2 and show that it directly interacts with coactivator NFY to influence cholesterogenic gene expression. Our work offers new insights into mechanisms orchestrating selective promoter activation in metabolic control and a model by which hnRNPs can impact metabolic health and disease states.

CLIPseq of hnRNP A1 from the spinal cords of mice with experimental autoimmune encephalomyelitis

Project description:Experimental autoimmune encephalomyelitis (EAE) is a mouse model for multiple sclerosis (MS) a chronic autoimmune disease of the central nervous system. We have observed dysfunction of the RNA binding protein hnRNP A1 in neurons from the brains of patients with MS, and the spinal cords of mice with EAE. Here, we sought to characterize the consequences of EAE-induced dysfunction of hnRNP A1 on the RNAs it binds by using CLIPseq to establish both the normal central nervous system RNA binding profile of hnRNP A1 in the spinal cords of naive mice, and any alterations to the binding profile of hnRNP A1 in the spinal cords of mice with EAE.

Effects of hnRNP A1 on gene expression in oral squamous cell carcinoma

Project description:To find the discover target genes regulated by hnRNP A1 in oral squamous cell carcinoma, NimbleGen 12x135K microarrays were used to find the gene expression changes between hnRNP A1 or non-specific (NS) siRNA treated oral cancer cells. Cal27 cells were treated with hnRNP A1 or non-specific (NS) siRNA twice in a 48-hour interval. After 96 hours, total RNAs were collected for microarray assay. Total RNAs from hnRNP A1 knockdown (3 samples) or NS siRNA treated cells (3 samples) were used for chip experiment (6 chips). Each chip measures the expression levels of human 45,033 genes. NimbleGen One-Color DNA Labeling Kit was used for sample labeling. Hybridization was performed in NimbleGen Hybridization System. After washing, slides were scanned with Axon GenePix 4000B scanner. Data was extracted and normalized using NimbleScan v2.5 Software.

Muscle Developmental Defects in Heterogeneous Nuclear Ribonucleoprotein A1 Knockout Mice

Project description:Transcriptome analysis of total RNA samples from heart tissue of knockout mice Alternative splicing is the main mechanism to increase protein diversity from an mRNA. Heterogeneous ribonucleoprotein (hnRNP) family members are vital regulators of alternative splicing. The hnRNP A1 is the most well-known protein in this family, but its role in embryonic development is not well understood. We generated hnRNP A1 knockout mice to study the function of hnRNP A1 in vivo. The hnRNP A1-depleted mice showed embryonic lethality because of muscle developmental defects. In a previous study, cellular hnRNP A2/B1 was reported to be capable of compensating for the expression of hnRNP A1. However, this phenomenon did not occur in the hnRNP A1 heterozygous mice in vivo. We demonstrated that hnRNP A1 regulated muscle-related genes expression and alternative splicing. In summary, our data demonstrated that hnRNP A1 plays a critical role in embryonic muscle development. Understanding the effects of hnRNP A1 in vivo may help to define the function of hnRNP A1 in alternative splicing.

40S hnRNP particles are a novel class of nuclear biomolecular condensates

Project description:Heterogenous nuclear ribonucleoproteins (hnRNPs) are abundant proteins implicated in various steps of RNA processing that assemble on nuclear RNA into larger complexes termed 40S hnRNP particles. Despite their initial discovery 55 years ago, our understanding of these intriguing macromolecular assemblies remains limited. We biochemically purified native 40S hnRNP particles and determined their complete protein composition by label-free quantitative mass spectrometry, identifying A-group and C-group hnRNPs as the major protein constituents.
