Regulation of the core pre-mRNA splicing machinery by MYC and PRMT5 is essential to sustain lymphomagenesis [fetal liver]

Project description:Over-expressed MYC binds to virtually all active promoters within a cell, although with different binding affinities, and modulates gene expression, both positively and negatively. Here, we show that during lymphomagenesis in Eµ-myc transgenic mice, MYC directly up-regulates the transcription of the core snRNP assembly genes, including PRMT5, an arginine methyltransferase, that methylates Sm proteins as an early step in lymphomagenesis. This coordinated regulatory effect is direct and is critical for snRNP biogenesis, the maintenance of effective mRNA splicing and cellular viability in cycling cells, in either fibroblasts or B-cells. Total RNA obtained from isolated fetal livers subjected to 24 hours of OHT or EtOH (control).

Regulation of constitutive and alternative splicing by PRMT5 reveals a role for Mdm4 pre-mRNA in sensing defects in the spliceosomal machinery (RNA-Seq)

Project description:Protein Arginine MethylTransferase 5 (PRMT5) is known to mediate epigenetic control on chromatin and to functionally regulate components of the splicing machinery. In this study we show that selective deletion of PRMT5 in different organs leads to cell cycle arrest and apoptosis. At the molecular level, PRMT5 depletion results in reduced methylation of Sm proteins, aberrant constitutive splicing and in the Alternative Splicing (AS) of specific mRNAs. We identify Mdm4 as one of these mRNAs, which due to its weak 5’-Donor site, acts as a sensor of splicing defects and transduces the signal to activate the p53 response, providing a mechanistic explanation of the phenotype observed in PRMT5 conditional knockout mice. Our data demonstrate a key role of PRMT5, together with p53, as guardians of the transcriptome. This will have fundamental implications in our understanding of PRMT5 activity, both in physiological conditions, as well as pathological conditions, including cancer and neurological diseases. Total RNA was extracted from control and Prmt5 depleted Neural Stem/Progenitors Cells (NPCs) and Mouse Embryonic Fibroblasts (MEFs). Prmt5 depleted cells were treated with 4-OHT 24 hours before splitting to induce PRMT5 knockout and final libraries were sequenced in triplicates on Illumina HiSeq 2000.

The final cRNA samples were hybridized to Illumina MouseRef-8 V2 arrays in quadruplicates.

PRMT5 Promotes Progression of Chronic Lymphocytic Leukemia [scRNA-Seq]

Project description:Purpose: Richter’s Transformation (RT) is a poorly understood and often fatal progression of chronic lymphocytic leukemia (CLL) manifesting histologically as diffuse large B-cell lymphoma. PRMT5 is implicated in lymphomagenesis, but its role in CLL or RT progression is unknown. We demonstrate herein that tumors uniformly overexpress PRMT5 in patients with progression to RT. Furthermore, mice with B-specific overexpression of hPRMT5 developed a B-lymphoid expansion with increased risk of death, and Eµ-PRMT5/TCL1 double transgenic mice uniformly developed a highly aggressive disease that histologically resembles RT; where large-scale transcriptional profiling identified unique oncogenic pathways that mediate PRMT5-driven disease progression. Taken together, the discovery that PRMT5 drives oncogenic pathways promoting RT provides a compelling rationale for clinical investigation of PRMT5 inhibitors such as PRT382 in aggressive CLL/RT cases
