RNA sequencing of patient derived xenograft sample ALL-811 using prime-seq

We establish a Cre-ERT2-loxP (causes recombination, estrogen receptor mutant T2, locus of X-over P1) based inducible RNAi- (ribonucleic acid interference) mediated gene silencing system in patient-derived xenograft (PDX) models of acute leukemias in vivo. Mimicking anti-cancer therapy in patients, gene inhibition is initiated in mice harboring orthotopic tumors. In fluorochrome guided, competitive in vivo trials, silencing of DUX4 (double homeobox 4) playes an essential role in patients’ leukemias carrying the recently described DUX4-IGH (immunoglobulin heavy chain) translocation, while the downstream mediator DDIT4L (DNA-damage-inducible transcript 4 like) is identified as therapeutic vulnerability. DUX4 KD and control PDX cells were isolated out of the murine bone marrow after induction of the shRNA expression by tamoxifen. the mRNA expression pattern was analyzed. >>> Raw data not provided as German law does not allow human raw sequence data to be publicly available. <<<
