Oncogenic activation of the BRAF serine/threonine kinase has been associated with initiation and maintenance of melanoma tumors. As such, development of pharmacologic agents to target RAF proteins or their effector kinases is an area of intense investigation. Here we report the biological properties of GDC-0879, a highly selective, potent, and orally bioavailable RAF small-molecule inhibitor. We used extracellular signal-regulated kinase (ERK)-1/2 and mitogen-activated protein kinase/ERK kinase ...[more]

Endogenous expression of an oncogenic PI3K mutation leads to activated PI3K pathway signaling and an invasive phenotype

Project description:The PTEN/PI3K pathway is commonly mutated in cancer and therefore represents a rational target for therapeutic intervention. In order to investigate the primary phenotype(s) mediated by mutant PIK3CA in a clean and highly patient-relevant context, we utilized a non-tumorigenic MCF10A parental and isogenic knock-in cell line that harbors a common activating PIK3CA kinase domain mutation (H1047R). We found that introduction of an endogenously mutated PIK3CA primarily results in a marked epithelial-mesenchymal transition (EMT) and invasive phenotype compared to isogenic wild-type cells. Moreover, a potent and selective inhibitor of PIK3CA (GDC-0941) was highly effective and selective on reversing this phenotype compared to cell-proliferation, highlighting a potential new paradigm for studying PI3K-pathway targeted agents. Keywords: Expression Array Gene expression profiles from a parental MCF10A breast line and an MCF10A clone that has a PI3K activating mutation (H1047R) knocked-in. We plated the cells in 10cm dishes overnight in media with serum, but lacking EGF or insulin. DMSO or GDC-0941 (PI3K inhibitor) at an EC50 concentration were added to triplicate plates of cells in the morning. After 4 hours the RNA was harvested using the Qiagen RNeasy kit. There are 12 samples total.

A combinatorial code for pattern formation in Drosophila oogenesis

Project description:Two-dimensional patterning of the follicular epithelium in Drosophila oogenesis is required for the formation of three-dimensional eggshell structures. Our analysis of a large number of published gene expression patterns in the follicle cells suggests that they follow a simple combinatorial code based on six spatial building blocks and the operations of union, difference, intersection, and addition. The building blocks are related to the distribution of inductive signals, provided by the highly conserved epidermal growth factor receptor and Decapentaplegic (DPP) pathways. We demonstrate the validity of the code by testing it against a set of patterns obtained in a large-scale transcriptional profiling experiment. Using the proposed code, we distinguish 36 distinct patterns for 81 genes expressed in the follicular epithelium and characterize their joint dynamics over four stages of oogenesis. The proposed combinatorial framework allows systematic analysis of the diversity and dynamics of two-dimensional transcriptional patterns and guides future studies of gene regulation. Keywords: EGFR, BMP, gain/loss-of-function RNA was isolated from hand dissected, stage 9-10 egg chambers. Five genetic backgrounds were profiled including: wild type, EGFR gain of function, EGFR loss of function, BMP gain of function, and BMP loss of function. Three biological replicates were hybridized for each pathway perturbation. The samples were split across two rounds of hybridization. Each round of hybridizations included three biological replicates for wild type: The first round included EGFR gof, EGFR lof, BMP gof, and wild type controls A1-A3 (GSM313514-16). For these 12 arrays the extraction, labeling, and hybridization steps were done in parallel. The second round included the BMP lof and wild type controls B1-B3 (GSM313517-19). For these 6 arrays, the extraction, labeling, and hybridization steps were done in parallel.

SPR509: Lung metastasis

Project description:Determine gene expression differences between normal, metastatic and non-metastatic mouse lung tissue. Priming of the organ-specific premetastatic sites is thought to be an important yet incompletely understood step during metastasis. In this study, we show that the metastatic tumors we examined overexpress granulocyte-colony stimulating factor (G-CSF), which expands and mobilizes Ly6G+Ly6C+ granulocytes and facilitates their subsequent homing at distant organs even before the arrival of tumor cells. Moreover, G-CSF-mobilized Ly6G+Ly6C+ cells produce the Bv8 protein, which has been implicated in angiogenesis and mobilization of myeloid cells. Anti-G-CSF or anti-Bv8 antibodies significantly reduced lung metastasis. Transplantation of Bv8 null fetal liver cells into lethally irradiated hosts also reduced metastasis. We identified an unexpected role for Bv8: the ability to stimulate tumor cell migration through activation of one of the Bv8 receptors, prokineticin receptor (PKR)-1. Finally, we show that administration of recombinant G-CSF is sufficient to increase the numbers of Ly6G+Ly6C+ cells in organ-specific metastatic sites and results in enhanced metastatic ability of several tumors. 67NR and 4T1mouse breast carcinoma cell lines were injected into fourth mammary fat pad; lung tissue was collected when tumor reached volume of 50mm3. RNA was extracted using Qiagen kit.

The Regulatory Specificity of a Homeodomain Protein is Determined by Unique DNA-Binding Sequences

Project description:Homeodomain (HD) proteins comprise a large family of evolutionarily conserved transcription factors (TFs) having diverse developmental functions, yet they paradoxically recognize very similar DNA sequences. To investigate how HDs control cell-specific gene expression patterns, we determined the DNA binding specificities of a broad range of HDs critical for Drosophila embryonic mesoderm development. These studies revealed particular sequences that are bound by one HD and not by others. Such HD-preferred binding sites are overrepresented in the noncoding regions of genes that are regulated by the corresponding HD. Moreover, we show at single-cell resolution in intact embryos that the HD Slouch (Slou) controls myoblast gene expression through unique DNA sequences that are preferentially bound by Slou. These findings demonstrate that the sequence of a HD-binding site dictates which HD family member binds to and regulates a particular enhancer. This represents a novel mechanism for how cell type-specific TFs induce the distinct genetic programs of individual embryonic cells. Mesodermal cells were profiled from wild type, slou gain-of-function and msh gain-of-function backgrounds.

Expression profiling of BRAFV600E melanoma cell lines upon RAF inhibition

Project description:Microarray expression analysis to identify global changes in transcription in response to RAF inhibition. Genes under RAF control were identified in a panel of BRAFV600E tumor cells, following the short-term inhibition of RAF using a pan-RAF kinase inhibitor, PLX4032 (Plexxikon). For comparison with changes in gene expression in response to MEK inhibition using PD0325901 (Pfizer), the following array data was referenced: (http://www.ncbi.nlm.nih.gov/geo/ (accession no. GSE10086)). Cell lines growing in culture (n=5) were treated with the RAF inhibitor PLX4032 (250nM or 1000nM) or vehicle alone (0.1% DMSO) as control, for eight hours.

VEGF blockade enhances the antitumor effect of BRAFV600E inhibition.

Project description:The development of resistance remains a major obstacle to long-term disease control in cancer patients treated with targeted therapies. In BRAF-mutant mouse models, we demonstrate that although targeted inhibition of either BRAF or VEGF initially suppresses the growth of BRAF-mutant tumors, combined inhibition of both pathways results in apoptosis, long-lasting tumor responses, reduction in lung colonization, and delayed onset of acquired resistance to the BRAF inhibitor PLX4720. As well as inducing tumor vascular normalization and ameliorating hypoxia, this approach induces remodeling of the extracellular matrix, infiltration of macrophages with an M1-like phenotype, and reduction in cancer-associated fibroblasts. At the molecular level, this therapeutic regimen results in a de novo transcriptional signature, which sustains and explains the observed efficacy with regard to cancer progression. Collectively, our findings offer new biological rationales for the management of clinical resistance to BRAF inhibitors based on the combination between BRAFV600E inhibitors with anti-angiogenic regimens.

Differential sensitivity of melanoma cell lines with BRAFV600E mutation to the specific Raf inhibitor PLX4032.

Project description:Blocking oncogenic signaling induced by the BRAFV600E mutation is a promising approach for melanoma treatment. We tested the anti-tumor effects of a specific inhibitor of Raf protein kinases, PLX4032/RG7204, in melanoma cell lines. PLX4032 decreased signaling through the MAPK pathway only in cell lines with the BRAFV600E mutation. Seven out of 10 BRAFV600E mutant cell lines displayed sensitivity based on cell viability assays and three were resistant at concentrations up to 10 muM. Among the sensitive cell lines, four were highly sensitive with IC50 values below 1 muM, and three were moderately sensitive with IC50 values between 1 and 10 muM. There was evidence of MAPK pathway inhibition and cell cycle arrest in both sensitive and resistant cell lines. Genomic analysis by sequencing, genotyping of close to 400 oncogeninc mutations by mass spectrometry, and SNP arrays demonstrated no major differences in BRAF locus amplification or in other oncogenic events between sensitive and resistant cell lines. However, metabolic tracer uptake studies demonstrated that sensitive cell lines had a more profound inhibition of FDG uptake upon exposure to PLX4032 than resistant cell lines. In conclusion, BRAFV600E mutant melanoma cell lines displayed a range of sensitivities to PLX4032 and metabolic imaging using PET probes can be used to assess sensitivity.
