Project description:The CREB binding protein inhibitor ICG-001 suppresses pancreatic cancer growth We used microarrays to detail global gene expression changes in the pancreatic cancer cell line AsPC1 following treatment with ICG-001 or siRNA-mediated knockdown of CTNNB1 (beta-catenin) AsPC1 cells were treated with 10uM ICG-001 or vehicle control (DMSO) for either 6 hours or 24 hours. AsPC-1 cells were also separately transfected with 20nM control siRNA or CTNNB1 siRNA for 48 hours. RNA was extracted at these time points for hybridization to Affymetrix microarrays

Project description:Diffuse intrinsic pontine glioma (DIPG) is an aggressive and incurable childhood brain tumor for which new treatments are needed. A high throughput drug screen of 3600 pharmaceutical compounds found that anti-malarials, including quinacrine had potent activity against DIPG neurospheres. CBL0137 is a novel anti-cancer compound developed from quinacrine, which targets Facilitates Chromatin Transcription (FACT), a chromatin remodelling complex involved in transcription, replication, and DNA repair. We have found that CBL0137 displays profound cytotoxic activity against a panel of patient derived DIPG cultures, inhibiting cell proliferation and clonogenic potential, restoring tumor suppressor TP53 and Rb activity and inducing cell death through induction of apoptosis. Moreover, in an orthotopic model of DIPG, treatment with CBL0137 significantly extended animal survival. Histone mutations leading to the loss of histone trimethylation result in epigenetic dysregulation driving DIPG tumorigenesis. Treatment with CBL0137 targets this epigenetic defect, restoring both histone H3.3 acetylation and trimethylation and leading to tumor cell death. Combined epigenetic treatment with the histone deacetylase (HDAC) inhibitor panobinostat led to inhibition of the Rb/E2F1 pathway, and increased the enzymatic activity of enhancer of zeste homolog 2 (EZH2), leading to the restoration of H3K27 trimethylation. This combination therapy had synergistic activity against DIPG neurospheres with induction of apoptosis. Consistent with the in vitro results, the combination of CBL0137 and panobinostat significantly prolonged the survival of mice bearing DIPG orthografts suggesting a potential treatment strategy for DIPG.

Project description:DIPG is a paediatric brainstem glioma with no cure. Cellular immunotherapy approaches require specific targeting of unique and tumour specific cell surface antigens, however, there is a paucity of known targets for DIPG. In this study we have used a proteomics approach to interrogate an array of patient derived DIPG cell lines to identify potential immunotherapy targets

Project description:Diffuse intrinsic pontine glioma (DIPG) is one of the most devastating of paediatric malignancies and one for which no effective therapy exists. A major contributor to the failure of therapeutic trials is the assumption that biologic properties of brainstem tumours in children are identical to cerebral high-grade gliomas of adults. A better understanding of the biology of DIPG itself is needed in order to develop agents targeted more specifically to these childrenâs disease. Here we address this lack of knowledge by performing the first high-resolution SNP-based DNA microarray analysis of a series of DIPGs. Eleven samples (nine post-mortem and two pre-treatment surgical samples), the largest series thus far examined, were hybridized to Affymetrix SNP arrays (250k or 6.0). The study was approved by the Research Ethics Board at our institution (Hospital for Sick Children, Toronto, Ontario, Canada). All Array findings were validated using quantitative-PCR, fluorescence in-situ hybridization, immunohistochemistry and/or microsatellite analysis. Analysis of DIPG copy number alterations showed recurrent changes distinct from those of paediatric supratentorial high-grade astrocytomas. 36% of DIPGs had gains in PDGFRA and all showed PDGF-R-α expression. Gains in PARP-1 were identified in 3 cases. Pathway analysis revealed genes with loss of heterozygosity were enriched for DNA repair pathways. Our data provides the first, comprehensive high-resolution genomic analysis of paediatric DIPG. Our findings of recurrent involvement of the PDGFR pathway as well as defects in DNA repair pathways coupled with gain of PARP-1 highlight two potential, biologically-based, therapeutic targets directed specifically at this devastating disease. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from snap frozen biopsy and autopsy brain tissue from DIPG patients. Copy number analysis of Affymetrix 250K and 6.0 SNP arrays was performed for 11 paediatric DIPG samples, 7 matched normal brain samples, and HapMap samples.
