 Cancer CellStudy sheds light on how pancreatic cancer begins Research led by scientists at the University of California, San Diego and UC San Francisco Schools of Medicine examined the tumor-initiating events leading to pancreatic cancer (also called pancreatic ductal adenocarcinoma or PDA) in mice. Their work, published on line November 29 in the journal Cancer Cell, may help in the search for earlier detection methods and treatments.

Cancer CellStudy helps resolve debate about how tumors spread A team of scientists, led by researchers at the University of California, San Diego School of Medicine, has shown for the first time how cancer cells control the ON/OFF switch of a program used by developing embryos to effectively metastasize in vivo, breaking free and spreading to other parts of the body, where they can proliferate and grow into secondary tumors.

Proceedings of the National Academy of SciencesResearchers create a fly to study how a normal cell turns cancerous The wing of a fruit fly may hold the key to unraveling the genetic and molecular events that transform a normal cell into a cancerous one. The study, conducted on Drosophila melanogaster by scientists at the IRB Barcelona has reproduced each of the steps known to take place when a healthy cell turns cancerous. The researchers have thus provided an inexpensive and effective model that will allow to scrutinize the genes and molecules involved in each step. Contact: Sònia Armengou

FASEB JournalNew genetic test detects early breast cancer and identifies future risk Breast cancer detection has improved, but more work remains to ensure accurate diagnosis, and to assess future risk. Researchers are developing a test of gene action that predicts cancer risk at first diagnosis, and into the future. This research in The FASEB Journal discusses how genetic switches, which are turned on and off in regular cellular development, can be analyzed in minute detail to determine the presence, or risk, of breast cancer growth.

NatureCOUP-TFII sparks prostate cancer progression Which cancers are essentially indolent and present no risk and which are life threatening? Which can be watched and which need aggressive treatment? Drs. Ming-Jer and Sophia Tsai both professors in the department of molecular and cellular biology at Baylor College of Medicine, think a receptor called COUP-TFII that they have long studied may point the way to an answer.

Science Translational MedicineJohns Hopkins scientists pair blood test and gene sequencing to detect cancer Scientists at the Johns Hopkins Kimmel Cancer Center have combined the ability to detect cancer DNA in the blood with genome sequencing technology in a test that could be used to screen for cancers, monitor cancer patients for recurrence and find residual cancer left after surgery.

Journal of Lipid ResearchAnalysis of conflicting fish oil studies finds that omega-3 fatty acids still matter A new analysis helps to sort through conflicting findings from literally hundreds of studies on use of omega-3 fatty acids for heart disease. It concludes that they still matter; they do work; and that modern therapies for cardiovascular disease help to mask the benefits omega-3 consumption might otherwise provide.

Tracking down smallest biomarkers A new device is to provide the metrological basis for promising biomarkers. The vacuum-compatible version of the Pilatus hybrid pixel detector for X-rays, which was developed by Dectris in cooperation with the Physikalisch-Technische Bundesanstalt, allows the size of nano-particles -- which, to date, have been difficult to characterize -- to be determined using small-angle X-ray scattering at low photon energies.
