Description
MYC 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.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Ars2 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.

Description
Craniosynostosis (CS) is the congenital premature fusion of one or more cranial sutures and represents the more prevalent craniofacial malformation in humans, with an overall incidence of 1 out of 2000-3000 live births. Non-syndromic craniosynostoses (NSC) are believed to be multifactorial disorders, with a strong genetic component, due to possible genegene or geneenvironment interactions that remain to be clearly identified. In this study we delved into the molecular signaling acting in calvarial tissue and cells from patients affected by nonsynodromic midline craniosynostosis, using a comparative analysis between fused and unfused sutures of each affected individuals. Using comparative microarray tissue gene expression profiling we have identified a subset of genes involved in the structure and function of the primary cilium, including the Bardet-Biedl syndrome 9 (BBS9) gene, which was recently associated to sagittal synostosis in a GWAS study. We therefore characterized BBS9 expression and cilium-related signaling in cells isolated from patients calvarial bone.
