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

ABSTRACT: 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).

Next generation sequencing identifies small RNA expression in FLT3-ITD+ AML (MV4-11) cell lines

Project description:The expression level of microRNAs in FLT3-ITD+ AML is unknown. Using empty vector (EV) lentiviral CRISPR-Cas9 infected FLT3-ITD+ AML cell lines (MV4-11 cells), we performed next generation RNA sequencing on small RNAs to determine microRNA expression level in these cells. We found a variety of evolutionarily conserved and non-conserved microRNAs expressed in our cells of interest. Small RNAseq on EV lentiviral CRISPR-Cas9 infected MV4-11 cell lines was performed on triplicate cultures.

Expression profile of wild type (WT) vs miR-155-/- in FLT3-ITD+ AML (MV4-11) cell lines

Project description:The expression profile in miR-155-/- FLT3-ITD+ AML is unknown. Using empty vector (EV) or two distinct miR-155 (S3 or S10) lentiviral CRISPR-Cas9 infected FLT3-ITD+ AML cell lines (MV4-11 cells), we performed next generation RNA sequencing to determine the expression profile in these cells dependent on miR-155. We found a number of pathways dysregulated, including STAT5 activation. RNAseq was performed on EV or miR-155 lentiviral CRISPR-Cas9 infected MV4-11 cell lines in triplicate cultures.

PRMT5-interacting proteins detected in Hey cells LC–MS

Project description:Our previous results indicated that PRMT5 is involved in CDDP resistance and may be regulated by phosphorylation modification. To further explore the mechanism of PRMT5 involved in CDDP resistance, PRMT5-interacting proteins were screened for potential PRMT5 kinases by mass spectrometry.

Identification of PRMT5 phosphorylation sites in Hey cells LC-MS

Project description:Previous studies have shown that PRMT5 undergoes various PTMs, including phosphorylation and arginine methylation. In our investigation of PRMT5's PTMs, we detected elevated phospho-Ser/Thr levels of PRMT5 in CDDP-resistant ovarian cancer cells Hey compared to their parental counterparts by co-immunoprecipitation of PRMT5. To further identify the phosphorylation sites that may be involved in the CDDP resistance mechanism, we identified the phosphorylation modification sites of PRMT5 by mass spectrometry.

PRMT5 protects genomic integrity during global DNA demethylation in primordial germ cells and preimplantation embryos

Project description:Primordial germ cells (PGCs) and preimplantation embryos undergo epigenetic reprogramming, which entails comprehensive erasure of DNA methylation. We found that PRMT5, an arginine methyltransferase, translocates from the cytoplasm to the nucleus during this process. Here we show that conditional loss of PRMT5 in early PGCs caused complete male and female sterility, which is preceded by upregulation of LINE1 and IAP transposons and DNA damage response. Similarly, loss of maternal-zygotic PRMT5 also leads to IAP upregulation and early embryonic lethality. We detected the PRMT5-catalysed repressive H2A/H4R3me2s modification on LINE1 and IAP in early wildtype PGCs, directly implicating this mark in the maintenance of transposon silencing during DNA hypomethylation. PRMT5 subsequently translocates back to the cytoplasm of PGCs to participate in the previously described PIWI-interacting RNA (piRNA) pathway that promotes transposon silencing via de novo DNA re-methylation. Thus, PRMT5 has a novel direct role in genome defense during preimplantation development and in PGCs at the time of global DNA demethylation PGCs mRNA profiles of embryonic day 11.5 dpc control (Blimp1Cre;Prmt5flox/+) and Prmt5 germ cell knockout (Blimp1Cre;Prmt5 flox/flox) were generated by deep sequencing (SOLiD next generation sequencing).
