View SamplesWe performed morphogen-directed differentiation of human PSCs into HE followed by combinatorial screening of 26 candidate HSC-specifying TFs for the potential to promote hematopoietic engraftment in irradiated immune deficient murine hosts. We recovered seven TFs (ERG, HOXA5, HOXA9, HOXA10, LCOR, RUNX1, SPI1) that together were sufficient to convert HE into hematopoietic stem and progenitor cells (HSPCs) that engraft primary and secondary murine recipients Overall design: Examination of expression pattern in hematopoietic cells.

View SamplesRNA-seq was performed to assess gene expression alterations by the addition of serial oncogenic hits (mutant-IDH1, P53 knockdown and ATRX knockdown) in human neural stem cells. Overall design: All RNA-seq was performed in duplicates, there are four conditions total. Vector NSCs are the control line and have an empty mCherry vector and a scramble shRNA vector. One hit NSCs express mutant-IDH1 and have a scamble shRNA vector. Two-hit NSCs express mutant IDH1 and have p53 knockdown. Three-hit NSCs express mutant-IDH1, P53 knockdown and ATRX knockdown.

Ars2 promotes proper replication-dependent histone mRNA 3' end formation.
Specimen part, Cell line, Treatment
View SamplesArs2 is a component of the nuclear cap-binding complex that is required for cellular proliferation and contributes to microRNA biogenesis. Arrays were performed to determine the repertoire of genes that change following knock-down of Ars2. Knock-down of DGCR8 was also performed to determine which changes in Ars2 knock-down cells resulted from defects in microRNA expression.

View SamplesMYC is a major oncogenic driver of Multiple Myeloma (MM) and yet almost no therapeutic agents exist that target MYC in MM. Here we report that the let-7 biogenesis inhibitor LIN28B correlates with MYC expression in MM and is associated with adverse outcome. We also demonstrate that the LIN28B/let-7 axis modulates the expression of MYC, itself a let-7 target. Further, perturbation of the axis regulates the proliferation of MM cells in vivo in a xenograft tumor model. RNA sequencing and gene set enrichment analyses of CRISPR-engineered cells further suggest that the LIN28/let-7 axis regulates MYC and cell cycle pathways in MM. We provide proof-of-principle for therapeutic regulation of MYC through let-7 with an LNA-GapmeR containing a let-7b mimic in vivo, demonstrating that high levels of let-7 expression repress tumor growth by regulating MYC expression. These findings reveal a novel mechanism of therapeutic targeting of MYC through the LIN28B/let-7 axis in MM that may impact other MYC dependent cancers as well. Overall design: RNA sequencing of MOLP-8 cells transduced with lentiCRISPRv2 scrambled control or containing a sgRNA against LIN28B. Both control and LIN28B KO cells were sequenced in triplicate.
The LIN28B/let-7 axis is a novel therapeutic pathway in multiple myeloma.
