Detection of transcriptome changes caused by knockdown of Ptbp1 in U251 GBM cells

ABSTRACT: We demonstrated that knocking down Ptbp1 can reprogram GBM cells into neuron-like cells. In order to further explore the mechanism of Ptbp1 causing this phenomenon, we performed mRNA sequencing on U251 cells infected with sh-Luci-3d, sh-Ptbp1-3d and sh-Ptbp1-7d.

HOXA9 transcriptomic analysis in GBM cell lines (U87MG, U251 and primary GBML18) and in immortalized human astrocytes (hTERT/E6/E7)

Project description:Assess gene expression patterns upon HOXA9 ectopic expression in U87MG GBM cell line and hTERT/E6/E7 immortalized human astrocytes, and HOXA9 silencing in U251 and GBML18 GBM cell lines. U87MG and hTERT/E6/E7 were retrovirally-infected with an MSCV control vector (MSCV-Control) or with a construct containing the coding region of HOXA9 (MSCV-HOXA9), resulting in U87MG-Control, U87MG-HOXA9, hTERT/E6/E7-Control and hTERT/E6/E7-HOXA9 cell lines. GBML18 and U251 cells were transfected with HOXA9 gene-specific shRNA sequences (shHOXA9) or a non-efective shRNA (shControl) in pGFP-V-RS plasmid, resulting in U251-shControl, U251-shHOXA9, GBML18-shControl and GBML18-shHOXA9 cell lines. Four experimental replicates for HOXA9 overexpression cell lines, and three for HOXA9 silencing cell lines were performed.

iiCLIP protocol benchmarking with PTBP1

Project description:We describe an improved individual nucleotide resolution CLIP protocol (iiCLIP), which can be completed within 4 days from UV crosslinking to libraries for sequencing. For benchmarking, we directly compared PTBP1 iiCLIP libraries with the iCLIP2 protocol produced under standardised conditions with 1 million HEK293 cells, and with public eCLIP and iCLIP PTBP1 data. There are 3 PTBP1 iiCLIP libraries, 1 input iiCLIP library and 1 PTBP1 iCLIP2 library produced in this study.

Proteome changes in PTBP1 deficient hematopoietic cells

Project description:Ribosomopathies constitute a range of disabling conditions associated with defective protein synthesis mainly affecting hematopoietic stem cells (HSCs) and erythroid development. Here we demonstrate that deletion of Polypyrimidine Tract Binding Protein 1 (PTBP1) in the hematopoietic compartment led to the development of a ribosomopathy-like condition. Specifically, loss of PTBP1 was associated with a decrease in HSC self-renewal, erythroid differentiation and protein synthesis. Consistent with its function as a splicing regulator, PTBP1 deficiency led to splicing defects in hundreds of genes and we demonstrate that the up-regulation of a specific isoform of CDC42 could partly mimic the protein synthesis defect associated with loss of PTBP1. Furthermore, PTBP1 deficiency was associated with a marked defect in ribosome biogenesis and a selective reduction in the translation of mRNAs encoding ribosomal proteins. Collectively, this work identifies PTBP1 as a key integrator of ribosomal functions and highlights the broad functional repertoire of RNA binding proteins.
