    During the 2000 US Presidential election, the terms “blue states” and “red states” emerged as a way to describe the political landscape of the United States. While these terms have become common heuristics used to organize how people think about politics, there is no singular agreed upon interpretation of what these terms tell us about America politics. This paper reviews the literature on framing and then discusses the identification of six media frames constructed around these terms between 2004 and 2012. Then, using a sample of 607 US newspaper articles, quantitative analysis indicates that the prevalence of particular frames changes during Presidential election years and by types of author. Overall, we find that frames vary in frequency depending on when the publication date and type of author, while also exploring how writers have used increasingly applied these terms towards seemingly apolitical realms of everyday life

    Integrated Genomic Characterization Reveals Novel, Therapeutically Relevant Drug Targets in FGFR and EGFR Pathways in Sporadic Intrahepatic Cholangiocarcinoma

    <div><p>Advanced cholangiocarcinoma continues to harbor a difficult prognosis and therapeutic options have been limited. During the course of a clinical trial of whole genomic sequencing seeking druggable targets, we examined six patients with advanced cholangiocarcinoma. Integrated genome-wide and whole transcriptome sequence analyses were performed on tumors from six patients with advanced, sporadic intrahepatic cholangiocarcinoma (SIC) to identify potential therapeutically actionable events. Among the somatic events captured in our analysis, we uncovered two novel therapeutically relevant genomic contexts that when acted upon, resulted in preliminary evidence of anti-tumor activity. Genome-wide structural analysis of sequence data revealed recurrent translocation events involving the <i>FGFR2</i> locus in three of six assessed patients. These observations and supporting evidence triggered the use of FGFR inhibitors in these patients. In one example, preliminary anti-tumor activity of pazopanib (<i>in vitro</i> FGFR2 IC<sub>50</sub>≈350 nM) was noted in a patient with an <i>FGFR2-TACC3</i> fusion. After progression on pazopanib, the same patient also had stable disease on ponatinib, a pan-FGFR inhibitor (<i>in vitro</i>, FGFR2 IC<sub>50</sub>≈8 nM). In an independent non-FGFR2 translocation patient, exome and transcriptome analysis revealed an allele specific somatic nonsense mutation (E384X) in <i>ERRFI1</i>, a direct negative regulator of <i>EGFR</i> activation. Rapid and robust disease regression was noted in this <i>ERRFI1</i> inactivated tumor when treated with erlotinib, an EGFR kinase inhibitor. <i>FGFR2</i> fusions and <i>ERRFI</i> mutations may represent novel targets in sporadic intrahepatic cholangiocarcinoma and trials should be characterized in larger cohorts of patients with these aberrations.</p></div

    <p><b>A</b>) CT images of patient 3 at baseline and three months demonstrate significant tumor shrinkage (red marks). CT demonstrates right retroperitoneal lymph nodes decreasing from 7.6 cm to 2.9 cm and left retroperitoneal lymph nodes decreasing from 3.3 cm to 1.7 cm. <b>B</b>) PET images of patient 3 at baseline and three months demonstrate significant tumor shrinkage (red arrows). Hypermetabolic areas corresponding to right retroperitoneal lymph nodes demonstrate decrease from 8 cm longest diameter to imperceptible and left retroperitoneal lymph nodes decreasing from 4.2 cm to 1.4 cm. Both regions demonstrated significant reduction in metabolic activity.</p

    Copy number changes and structural rearrangements.

    <p>Whole genome data was utilized to determine copy number alterations and structural rearrangements in the genome for Patients 1–5. WGS was not conducted for patient 6. Red indicates copy number gain, green copy number loss and blue lines indicate structural rearrangements. Significant variability between samples was observed for both copy number changes and structural rearrangements. Patient 5 presented with numerous copy number changes and structural rearrangements contrasting with patient 4 who had minimal structural rearrangements and much smaller regions of copy number changes. Patient 3 is characterized by a large number of structural rearrangements with almost no copy number alterations; in contrast, Patient 1 has a moderate number of structural variations, but has large regions of copy number gain and loss. Patient 2 has a moderate number of structural rearrangements with multiple focal amplifications across the genome.</p

    <p>Functional effects of high confidence sequence variations for all of the patients were identified as described in the Methods. The abundance of variations in each functional category is provided as percentages relative to the total number of high confidence variations and raw counts are provided in <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004135#pgen-1004135-t001" target="_blank"><b>Table 1</b></a>. For categories where the percentage was less than 5%, values are not shown. Summaries by individual patients are shown as follows: <b>A</b>) Patient 1, <b>B</b>) Patient 2, <b>C</b>) Patient 3, <b>D</b>) Patient 4, <b>E</b>) Patient 5, and <b>F</b>) Patient 6. Nonsynonymous single nucleotide variations were the predominant class in all of the patients. Two patients, Patients 1 and 2 also accumulated a high number of synonymous mutations in comparison to the other patients; Patient 5 carries the most stops gained likely contributing to a higher number of pseudogenes in comparison to the others; Patient 5 was also the only patient to carry several predicted high impact mutations that affect the splice site acceptor regions (light green, percentage <5%). In addition to the major functional classes summarized, Patient 6 also carried a codon change plus insertion variation.</p
