PRMT5 knockdown changes gene expression in prostate cancer cells

Project description:PRMT5 is the major type II protein arginine methyltransferase catalyzing the symmetric dimethylation of arginine. Recent reports have indicated that PRMT5 is overexpressed in multiple cancer types, including prostate. However, the exact contribution of PRMT5 to prostate tumorigenesis is unknown. To explore the functional role of PRMT5 in prostate cancer (PCa), we knocked down PRMT5 by lentiviral shRNAs in both AR-dependent LNCaP cells and AR-independent PC3 cells. Our data suggests that PRMT5 regulates PCa cell biology. To further identify PRMT5-regulated genes in PCa, we performed paired-end RNA-seq analysis in PC3 and LNCaP cells with or without PRMT5-knockdown.

PRMT5 regulated transcriptome in prostate cancer cells

Project description:Compared to intensely studied DNA methylation, protein methylation is less studied. PRMT5 is the major type II protein arginine methyltransferase catalyzing the symmetric dimethylation of arginine. Recent reports have indicated that PRMT5 is overexpressed in multiple cancer types, including prostate. However, the exact contribution of PRMT5 to prostate tumorigenesis is unknown. To explore PRMT5 in prostate cancer (PCa) therapeutically, we utilized a recently developed selective small molecule PRMT5 inhibitor (PRMT5i, EPZ015666) that has shown in vivo potency in MCL models. To understand the molecular mechanisms of action of PRMT5i in PCa, we performed deep RNA-seq analysis in PC3 and LNCaP cells treated with or without PRMT5i at 4 μM for 4 days in vitro.

Identification of PRMT5 as a therapeutic target in cholangiocarcinoma [RNA-seq II]

Project description:Cholangiocarcinoma is a very aggressive cancer whose incidence is increasing. Moreover, chemotherapies are little effective and the response to immune checkpoint inhibitors is low. We have identified protein arginine-methyltransferase 5 (PRMT5) as a novel therapeutic target in cholangiocarcinoma. Treatment with PRMT5 inhibitor significantly restrains the growth of experimental cholangiocarcinoma model TAZ/AKT without adverse effects. Our findings support the evaluation of PRMT5 inhibitors in clinical trials.

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.

Small-molecule inhibition of PRMT5 activates p53 in erythropoiesis through perturbation of mRNA processing, transport and protein translation

Project description:The protein arginine methyltransferase PRMT5 catalyzes symmetric di-methylation of numerous proteins involved in epigenetic gene regulation, mRNA splicing and DNA repair. Several small molecule inhibitors of PRMT5 are in clinical trials for acute myeloid leukemia, myelodysplasia, lymphoma and metastatic solid tumors. Here, we report the development of a new potent and specific small molecule inhibitor of PRMT5 (CTX-034) that binds and competes for the arginine substrate binding pocket. CTX-034 suppresses erythroid progenitor growth 30-fold more potently than myeloid progenitor growth through activation of p53. Using a combination of RNA-seq and proteomics, we show that PRMT5 binds and methylates numerous proteins required for protein translation including RNA transport (Heterogeneous Nuclear Ribonucleoprotein A1), initiation of translation (Poly(A) Binding Protein Cytoplasmic 1) and ribosomal assembly (Ribosomal Protein S10). Using an in vivo mouse model of JAK2V617F-driven Polycythemia Vera, CTX-034 suppresses the formation of immature erythroblasts as effectively as the JAK inhibitor Ruxolitinib.

Chromatin-occupancy profiling of PRMT5 and METTL3 in prostate cancer cells

Project description:Prostate cancer (PCa) is the most frequently diagnosed malignancy in men worldwide. Epigenetic regulation has been recognized as a main mechanism of cancer evolution. PRMT5 is the major type II protein arginine methyltransferase catalyzing the symmetric dimethylation of arginine, and METTL3 is the enzymatic component of the large N6-adenosine-methyltransferase complex in mammalian responsible for N6-methyladenosine (m6A) modification in diverse RNA species. Both genes are found upregulated in PCa. However, their exact functional contribution to prostate tumorigenesis is unknown. As both proteins can regulate transcription via binding to chromatin, we seek to explore their DNA binding profiles in both AR+ LNCaP and AR- PC3 cells via recently developed CUT&Tag technique. Antibodies we used were Active Motif #61001 for PRMT5 and Abcam #195352 for METTL3. Our data suggests that both proteins regulate PCa cell biology, at least partially, through chromatin-binding and subsequent transcriptional regulation.
