Epigenetic Reprogramming Sensitizes CML Stem Cells to Combined EZH2 and Tyrosine
Published OnlineFirst September 14, 2016; DOI: 10.1158/2159-8290.CD-16-0263 RESEARCH BRIEF Epigenetic Reprogramming Sensitizes CML Stem Cells to Combined EZH2 and Tyrosine Kinase Inhibition Mary T.

Holyoake 2 , and David Vetrie 1 ABSTRACT A major obstacle to curing chronic myeloid leukemia (CML) is residual disease main- tained by tyrosine kinase inhibitor (TKI)–persistent leukemic stem cells (LSC). These are BCR–ABL1 kinase independent, refractory to apoptosis, and serve as a reservoir to drive relapse or TKI resistance. We demonstrate that Polycomb Repressive Complex 2 is misregulated in chronic phase CML LSCs. This is associated with extensive reprogramming of H3K27me3 targets in LSCs, thus sensi- tizing them to apoptosis upon treatment with an EZH2-specifi c inhibitor (EZH2i). EZH2i does not impair normal hematopoietic stem cell survival. Strikingly, treatment of primary CML cells with either EZH2i or TKI alone caused signifi cant upregulation of H3K27me3 targets, and combined treatment further potentiated these effects and resulted in signifi cant loss of LSCs compared to TKI alone, in vitro , and in long-term bone marrow murine xenografts. Our fi ndings point to a promising epigenetic-based thera- peutic strategy to more effectively target LSCs in patients with CML receiving TKIs. SIGNIFICANCE: In CML, TKI-persistent LSCs remain an obstacle to cure, and approaches to eradicate them remain a signifi cant unmet clinical need. -

Radin , Steven Johnson, Richard Purcell, Arnold S. Lippa RespireRx Pharmaceuticals, Inc., 126 Valley Road, Glen Rock, NJ, 07452, United States ARTICLE INFO ABSTRACT Keywords: Neurotrophin dysregulation has been implicated in a large number of neurodegenerative and neuropsychiatric Ampakine diseases. Unfortunately, neurotrophins cannot cross the blood brain barrier thus, novel means of up regulating BDNF their expression are greatly needed. It has been demonstrated previously that neurotrophins are up regulated in Cognitive enhancement response to increases in brain activity. Therefore, molecules that act as cognitive enhancers may provide a LTP clinical means of up regulating neurotrophin expression. Ampakines are a class of molecules that act as positive Neurotrophin allosteric modulators of AMPA-type glutamate receptors. Currently, they are being developed to prevent opioid- NGF induced respiratory depression without sacrificing the analgesic properties of the opioids. In addition, these molecules increase neuronal activity and have been shown to restore age-related deficits in LTP in aged rats. In the current study, we examined whether two different ampakines could increase levels of BDNF and NGF at doses that are active in behavioral measures of cognition. Results demonstrate that ampakines CX516 and CX691 induce differential increases in neurotrophins across several brain regions. Notable increases in NGF were ob- served in the dentate gyrus and piriform cortex while notable BDNF increases were observed in basolateral and lateral nuclei of the amygdala. -

Integral to this tool are the \seq2gene" and \gene2pathway" components in series that infer a quantitative pathway-level profile for each sample. The seq2gene function assigns phenotype-associated significance of genomic regions to gene-level scores, where the significance could be p-values of SNPs or point mutations, protein-binding affinity, or transcriptional expression level. The seq2gene function has the feasibility to assign non-exon regions to a range of neighboring genes besides the nearest one, thus facilitating the study of functional non-coding elements[2]. Then the gene2pathway summarizes gene-level measurements to pathway-level scores, comparing the quantity of significance for gene members within a pathway with those outside a pathway. -

Useful Information: WB:1:500 - 1:2000 Applications: FCM:1:200 - 1:400 ELISA:1:10000 Reactivity: Human Specificity: This antibody recognizes BCL2L10 protein. Purified recombinant fragment of human BCL2L10 (AA: 31-186) expressed Immunogen: in E. Coli. The protein encoded by this gene belongs to the BCL-2 protein family. BCL-2 family members form hetero- or homodimers and act as anti- or pro-apoptotic regulators that are involved in a wide variety of cellular activi- ties. The protein encoded by this gene contains conserved BH4, BH1 and BH2 domains. This protein can interact with other members of BCL-2 pro- tein family including BCL2, BCL2L1/BCL-X(L), and BAX. Overexpression of Description: this gene has been shown to suppress cell apoptosis possibly through the prevention of cytochrome C release from the mitochondria, and thus acti- vating caspase-3 activation. The mouse counterpart of this protein is found to interact with Apaf1 and forms a protein complex with Caspase 9, which suggests the involvement of this protein in APAF1 and CASPASE 9 related apoptotic pathway.

The syndrome is characterized by partial deletion of chromosome 6, which may arise in a number of ways. Case presentation: We report a 2.8-year old boy presenting with developmental delay and mild dysmorphisms. High-resolution oligonucleotide microarray analysis revealed with high precision a 2.5 Mb interstitial 6p deletion in the 6p22.3 region which encompasses 13 genes.

In addition, the participation of Borg proteins in important cellular processes such as 19 cell shape, directed migration and differentiation is slowly emerging, directly linking Borgs 20 with important physiological and pathological processes such as angiogenesis, neuro- 21 fi transmission and cancer-associated desmoplasia.

Highlights • Stable, bona fide BicD2 coiled-coils with distinct registries can be formed. • We provide evidence that a human disease mutation causes a coiled-coil registry shift. • A coiled-coil registry shift could relieve BicD2-autoinhibition upon cargo-binding. • The ability to undergo registry shifts may be an inherent property of coiled-coils.
