Small RNA sequencing of human K562 cells transduced with lentiviral vectors overexpressing RUNX1

ABSTRACT: miRNA-Sequencing of RUNX1 overexpressing K562 cells were compared to K562 cells transduced with an empty vector control to analyse the differential expression of miRNAs in hematopoiesis. K562 cells were transduced either with an empty lentiviral vector as control or a lentiviral vector overexpressing human RUNX1. The samples were biological triplicates and the results were validated by qRT-PCR using SYBR green.

Control and Bmi1-overexpressing adult murine neural stem cells

Project description:Neural stem cells were isolated from adult mouse subventricular zone and transduced with a Bmi1-overexpressing lentiviral vector or an empty vector control. Cells were grown as neurospheres (in non-adherent culture conditions) for three passages and RNA purifed (after four weeks).

Functional study on the cooperation of ASXL1 and RUNX1 mutations for myeloid leukemia transformation

Project description:BACKGROUND: Our previous studies showed that RUNX1 and ASXL1 mutations were frequently co-existed in chronic myelomonocytic leukemia (CMML) and clonal evolution of RUNX1 and/or ASXL1 occurred most frequently in chronic myeloid leukemia (CML) with myeloid blastic crisis. The molecular pathogenesis of cooperation of RUNX1 and ASXL1 mutations has not been reported yet. METHODS: Lentiviral-mediated stable transduction of RUNX1-WT/MT (R135T) in K562 cells which harboring ASXL1-MT (Y591X). RNA was extracted from stable cell line and used for gene-expression microarray analysis. RESULTS: For in vitro study, we overexpressed RUNX1-WT/MT (R135T) in K562 cells which harboring ASXL1-MT (Y591X). We found that RUNX1-MT augmented cell proliferation, colony formation, HOXA gene expression and inhibited megakaryocytic differentiation in ASXL1-MT K562 cells compared to RUNX1-WT or empty vector control. We performed gene expression profile of K562 cells overexpressed with EV, RUNX1-WT and RUNX1-R135T mutation. Gene expression microarray data revealed that 147 genes upregulated more than 2-fold in RUNX1-R135T expressing K562 cells compared to EV control cells. From gene expression data analysis, we found that inhibitor of DNA binding 1 (ID1), a key transcriptional regulator of hematopoietic stem cell (HSC) lineage commitment, is upregulated in RUNX1-R135T-transduced K562 cells compared to EV and RUNX1-WT-expressing cells.

Identification of interaction partners of PRMT6

Project description:To identify transcription factors of PRMT6 which could recruit PRMT6 to target genes, we used affinity purification of avi-tagged PRMT6 in combination with stable isotope labeling of amino acids in cell culture (SILAC) based mass spectrometry. For this, K562 cells were transduced with a lentiviral co expression vector for the BirA-ligase and avi-PRMT6 with a 21 amino acid taq, which is biotinylated in the cells. Cells expressing the BirA-ligase only served as a control. Avi-PRMT6 cells were grown in heavy SILAC medium and control cells in light SILAC medium for seven passages. Nuclear extracts were prepared from 1x108 cells and subjected to avi-PRMT6 affinity purification using magnetic streptavidin beads. Subsequently, the proteins were eluted from the beads. The eluates from the avi-PRMT6 and the control were mixed in a one to one ratio. Subsequently, we performed quantitative mass spectrometry (MS)-based analysis of the PRMT6 interactome.
