First-in-class cancer drug approved to fight melanoma
The US Food and Drug Administration (FDA) has approved the first cancer drug to inhibit a protein — called MEK — that acts in a pathway that fuels tumour growth. The drug, called Mekinist (trametinib), was approved on 29 May for use in advanced melanomas with specific mutations. Other MEK-targeting drugs are being studied in a wide range of tumours, including lung and thyroid cancers.

Barbara Brenner, breast cancer awareness advocate, dies at 61
Barbara Brenner, who directed Breast Cancer Action, a San Francisco-based breast cancer awareness group, for 15 years, died May 10 at her home in San Francisco. She was 61. Although she “beat the breast cancer odds,” as she once said, Ms. Brenner resigned her post in 2010 because of amyotrophic lateral sclerosis, a degenerative nerve disorder known as ALS.

Cancer de la prostate : le Jevtana bientôt remboursé
Marisol Touraine, la ministre de la santé, a annoncé, vendredi 31 mai, le remboursement en France du Jevtana, un traitement coûteux du groupe Sanofi contre le cancer de la prostate. Interpellée par l'Association nationale des malades du cancer de la prostate (Anamacap), Mme Touraine a indiqué sur France Info que le médicament serait pris en charge par l'assurance-maladie.

La FDA donne son feu vert à 2 nouveaux traitements contre le mélanome
Deux nouvelles thérapies ciblées du mélanome métastatique inopérable ainsi qu'un test diagnostic pour identifier le bon traitement ont reçu une autorisation de mise sur le marché (AMM) de la Food and Drug Administration (FDA). Les nouveaux agents, le dabrafenib (Tafinalar®) et le trametinib (Mekinist®), ont été développés par GlaxoSmithKline. Tous deux sont des traitements oraux mais ont des mécanismes d'action légèrement différents.

Focus: Integrated genomic characterization of endometrial carcinoma




We performed an integrated genomic, transcriptomic and proteomic characterization of 373 endometrial carcinomas using array- and sequencing-based technologies. Uterine serous tumours and ∼25% of high-grade endometrioid tumours had extensive copy number alterations, few DNA methylation changes, low oestrogen receptor/progesterone receptor levels, and frequent TP53 mutations. Most endometrioid tumours had few copy number alterations or TP53 mutations, but frequent mutations in PTEN, CTNNB1, PIK3CA, ARID1A and KRAS and novel mutations in the SWI/SNF chromatin remodelling complex gene ARID5B. A subset of endometrioid tumours that we identified had a markedly increased transversion mutation frequency and newly identified hotspot mutations in POLE. Our results classified endometrial cancers into four categories: POLE ultramutated, microsatellite instability hypermutated, copy-number low, and copy-number high. Uterine serous carcinomas share genomic features with ovarian serous and basal-like breast carcinomas. We demonstrated that the genomic features of endometrial carcinomas permit a reclassification that may affect post-surgical adjuvant treatment for women with aggressive tumours.

Focus: A physical sciences network characterization of non-tumorigenic and metastatic cells




To investigate the transition from non-cancerous to metastatic from a physical sciences perspective, the Physical Sciences-Oncology Centers (PS-OC) Network performed molecular and biophysical comparative studies of the non-tumorigenic MCF-10A and metastatic MDA-MB-231 breast epithelial cell lines, commonly used as models of cancer metastasis. Experiments were performed in 20 laboratories from 12 PS-OCs. Each laboratory was supplied with identical aliquots and common reagents and culture protocols. Analyses of these measurements revealed dramatic differences in their mechanics, migration, adhesion, oxygen response, and proteomic profiles. Model-based multi-omics approaches identified key differences between these cells' regulatory networks involved in morphology and survival. These results provide a multifaceted description of cellular parameters of two widely used cell lines and demonstrate the value of the PS-OC Network approach for integration of diverse experimental observations to elucidate the phenotypes associated with cancer metastasis.

The Way We Think about Cancer Must Evolve
Right now, as you read these words, your life is in danger. Somewhere within the vast self-contained micro-universe known as you, in one and possibly more of your trillions of cells, something is going wrong. A vital protein, perhaps, is being altered or destroyed as one cell divides to create another. The mutated cell, an incorrect version of its former self, will continue to multiply, compounding and extending its grotesque influence as an intruder and usurper, bent on its own self- preservation at your expense. It has become cancer.

Cancer : optimisme à géométrie variable
Le regard sur le cancer profondément évolué ces dernières décennies à la faveur des progrès de la médecine. Désormais, ce n’est plus seulement la fatalité et le pessimisme qui dominent lorsqu’on évoque ces pathologies. L’enquête d’opinion PACE (Patient Acces and Cancer Care Excellence) menée sous l’égide des laboratoires Lilly dans six pays (Allemagne, Italie, Royaume-Uni, Japon, Etats-Unis et France) auprès, dans chaque état, d’une centaine de patients, d'une centaine de professionnels de santé et de cinq cent personnes dans la population générale, confirme cette évolution.

Washington: Cancer Patients More Prone to Bankruptcy
A study of cancer patients in Washington State has found they were twice as likely to file for bankruptcy as people without cancer. The study, led by researchers from the Fred Hutchinson Cancer Research Center in Seattle, linked bankruptcy court records and information from the regional cancer registry on about 200,000 cancer patients, and compared them with a similar group of people from the same area who did not have cancer. Young people with cancer experienced the highest bankruptcy rates, the study found, up to 10 times the rate of bankruptcy filings among older age groups.

With this therapy — three days of the drug daunorubicin, which comes in a reddish color so distinctive that one of my patients, a former chemist, used it in his professional life as a dye for plastics, and seven days of the drug cytarabine, which is infused continuously over 168 hours — we offer them the chance to be cured of a disease moving like wildfire with a stiff breeze behind it at the height of drought.

Focus : The Genomic HyperBrowser: an analysis web server for genome-scale data





Abstract
The immense increase in availability of genomic scale datasets, such as those provided by the ENCODE and Roadmap Epigenomics projects, presents unprecedented opportunities for individual researchers to pose novel falsifiable biological questions. With this opportunity, however, researchers are faced with the challenge of how to best analyze and interpret their genome-scale datasets. A powerful way of representing genome-scale data is as feature-specific coordinates relative to reference genome assemblies, i.e. as genomic tracks. The Genomic HyperBrowser (http://hyperbrowser.uio.no) is an open-ended web server for the analysis of genomic track data. Through the provision of several highly customizable components for processing and statistical analysis of genomic tracks, the HyperBrowser opens for a range of genomic investigations, related to, e.g., gene regulation, disease association or epigenetic modifications of the genome.
