PRMT5 is essential for sustaining normal adlut hematopoiesis

Project description:Examining the effects of PRMT5 loss on the gene expression profile of hematopoietic stem and progenitor cells We established the PRMT5 conditional KO mice, and bred the mice with Mx1 cre transgenic mice to delete PRMT5 in hematopoietic cells. We isolated hematopoetic stem and progenitor cells 3 days after PRMT5 deletion, and examined the gene expression files using RNA-sequencing.

The Effect of PRMT5 deficiency on thymic iNKT cells

Project description:Protein arginine methylation is a post-translational modification catalyzed by protein arginine methyltransferase (PRMT). To elucidate the role of PRMT5 in T cells, we generated T-cell specific PRMT5-deficient mice (Prmt5 flox/d Cd4-Cre mice) and found a severe loss of thymic iNKT cells as well as a reduced number in peripheral CD4+ and CD8+ T cells. As iNKT cells were significantly decreased in the stage 1, 2 and 3 of developmental stages, RNA-seq was performed using stage 1 iNKT cells of control and PRMT5-deficient mice. This transcriptome analysis will provide mechanistic insight into how PRMT5 contributes to thymic iNKT cell development.

The Sm protein methyltransferase PRMT5, is not required for primordial germ cell specification in mice

Project description:PRMT5 is a type II protein arginine methyltransferase with roles in stem cell biology, reprogramming, cancer and neurogenesis. During embryogenesis in the mouse it was hypothesized that PRMT5 functions with the master germline determinant BLIMP1 to promote primordial germ cell (PGC) specification. Using a Blimp1-Cre germline conditional knockout, we discovered that Prmt5 has no major role in murine germline specification, or the first global epigenetic reprogramming event involving depletion of cytosine methylation from DNA and histone H3 lysine 9 dimethylation from chromatin. Instead, we discovered that PRMT5 functions at the conclusion of PGC reprogramming I to promote proliferation, survival and expression of the gonadal germline program as marked by MVH. We show that PRMT5 regulates gene expression by promoting methylation of the Sm spliceosomal proteins, and significantly altering the spliced repertoire of RNAs in mammalian embryonic cells and primordial cells.

RNA deep sequencing to compare genome-wide differences between PRMT5/knockdown and control AML cells

Project description:We report the pro-leukemic activities of PRMT5 in AML partly via modulating the transcription of key genes. The goal of this experiment is to confirm the changes observed in expression of genes targeted by PRMT5 activities. RNA Deep sequencing was employed to validate and reproduce the changes measured by quantitative reverse transcription polymerase chain reaction (qRTâPCR) techniques. Total RNA samples from MV4-11 cell line (FLT3-ITD AML) following PRMT5 knockdown using specific short hairpin RNA (shRNA) was used to compare gene expression pattern between PRMT5/Knockdown and control (control: MV4-11 cells transduced with scramble control).

YAP regulates periosteal expansion in early fracture repair.

Project description:Periosteal expansion is a key process in the early stages of bone fracture repair. The periosteum is typically quiescent, but upon fracture it expands, periosteal cells proliferate and contribute to the formation of a cartilaginous callus . The early expansion of the periosteum is tightly regulated at the transcriptional level. However, the molecular mechanisms behind periosteal expansion are unknown. Here, we show that Yes-Associated Protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) mediate periosteal expansion and periosteal cell proliferation. Bone fracture results in increased numbers of YAP-expressing periosteal cells. Deletion of YAP from Osterix (Osx) expressing periosteal cells impairs early periosteal expansion. Mechanistically, YAP regulates both cell intrinsic and extrinsic transcriptional programs that allow for periosteal expansion. Specifically, we identified Bmp4 as a cell extrinsic factor regulated by YAP, that rescues the impairment of periosteal expansion upon YAP deletion. Together, these data establish YAP mediated molecular mechanisms that allow for periosteal expansion in the early stages of fracture repair.

PRMT5-regulates developmental myelination

Project description:PRMT5 is important for gliomas, however its physiological function in oligodendrocyte progenitors (OPCs), remains poorly understood. Here we report PRMT5 to be responsible for symmetric di-methylation of histone H4R3 (H4R3me2s) in OPC. PRMT5 depletion via CRISPR/Cas9 decreased H4R3me2s, altered the OPC transcriptome, and decreased OPC survival. Strikingly, these changes were associated with a marked increase of H4K5ac in OPC, but not in gliomas. Consistently, ChIP-sequencing analysis revealed increased genome-wide distribution of H4K5ac in PRMT5 knockout cells. In vitro acetylation assays demonstrated reciprocal inhibition between symmetric arginine methylation and lysine acetylation. Low H4R3me2s and high H4K5ac levels were also detected in OPC in mice with lineage-specific ablation of Prmt5 (Olig1-Cre;Prmt5fl/fl), resulting in severely impaired developmental myelination. Importantly, pharmacological inhibition of acetyltransferase activity partially rescued the effect of Prmt5 deletion on oligodendrocyte-specific gene transcripts. Collectively, we identify PRMT5 as a critical modulator of histone acetylation and OPC differentiation in early developmental myelination.

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

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 Prmt5F/F, and Prmt5 depleted Prmt5F/FNes (Nestin-Cre) Neural Stem/Progenitors Cells (NPCs). The final cRNA samples were hybridized to Illumina MouseRef-8 V2 arrays in quadruplicates.
