The diabetes drug metformin slows the growth of lung cancer cells and makes them more likely to be killed by radiotherapy, according to a study published in the British Journal of Cancer today. http://medicalxpress.com/news/2013-05-diabetes-drug-lung-cancer-vulnerable.html Cancer Wed, 01 May 2013 08:32:51 EST news286615964 A new study shows that the same sort of mathematical model that Google uses to predict which websites people want to visit may help researchers predict how lung cancer spreads through the human body. http://medicalxpress.com/news/2013-03-lung-cancer-page-google-playbook.html Cancer Mon, 25 Mar 2013 11:18:56 EST news283429130 Soybean meal is a bi-product following oil extraction from soybean seeds. It is rich in protein, which usually makes up around 40% of the nutritional components of the seeds and dependent on the line, and can also contain high oleic acid (a monounsaturated omega-9 fatty acid). http://medicalxpress.com/news/2013-03-highlights-strong-anti-cancer-properties-soybeans.html Health Wed, 20 Mar 2013 10:33:37 EST news282994411 (Medical Xpress)—Tumours need a steady supply of sufficient nutrients to be able to grow. In order to secure the nutrient availability, they secrete messenger compounds to stimulate neighbouring blood vessels to proliferate and sprout. Scientists from the Max Planck Institute for Neurological Research in Cologne, Germany, have now identified a new positive feedback loop involving the Vascular Endothelial Growth Factor (VEGF) and its receptor 'VEGFR-2' in human lung adenocarcinoma. http://medicalxpress.com/news/2013-03-fasting-tumour-cells.html Cancer Fri, 15 Mar 2013 07:25:31 EST news282551120 The vast majority – approximately 80 percent – of our DNA does not code for proteins, yet it gets transcribed into RNA. These RNA molecules are called non-coding and fulfill multiple tasks in the cell. Alongside a well-studied group of small RNAs, there is also a class of so-called long non-coding RNAs consisting of more than 200 nucleotides. http://medicalxpress.com/news/2013-02-rna-metastasis-lung-cancer.html Cancer Tue, 05 Feb 2013 09:52:54 EST news279280359 University of Pittsburgh Cancer Institute (UPCI) researchers have uncovered a technique to halt the growth of cancer cells, a discovery that led them to a potential new anti-cancer therapy. http://medicalxpress.com/news/2013-02-reveal-mechanism-halt-cancer-cell.html Cancer Mon, 04 Feb 2013 04:30:27 EST news279174611 A team of UC Davis investigators has discovered a protein on the surface of lung cancer cells that could prove to be an important new target for anti-cancer therapy. A series of experiments in mice with lung cancer showed that specific targeting of the protein with monoclonal antibodies reduced the size of tumors, lowered the occurrence of metastases and substantially lengthened survival time. The findings will be published in the November issue of Cancer Research. http://medicalxpress.com/news/2012-11-scientists-lung-cancer-treatment.html Cancer Thu, 01 Nov 2012 15:11:39 EST news271001442 (Medical Xpress)—A new technique that allows scientists to grow lung cancer cells in three dimensions could accelerate discoveries for a type of cancer that has benefited little from scientific research over the last several decades. http://medicalxpress.com/news/2012-10-d-lung-cancer-mimics-real.html Cancer Thu, 11 Oct 2012 07:25:41 EST news269159120 More effective treatments for one of the deadliest forms of cancer are one step closer thanks to groundbreaking research from an international collaborative study. http://medicalxpress.com/news/2012-10-breakthrough-lung-cancer-vulnerabilities-therapy.html Cancer Mon, 01 Oct 2012 15:00:37 EST news268315602 (Medical Xpress)—Why do many heavy smokers evade lung cancer while others who have never lit up die of the disease? The question has vexed scientists for decades. http://medicalxpress.com/news/2012-09-key-immune-cell-role-lung.html Cancer Fri, 21 Sep 2012 07:01:27 EST news267429678 Many lung cancers are driven by mutations in the epidermal growth-factor receptor (EGFR), and so it makes sense that many successful modern treatments block EGFR activity. Unfortunately, cancers inevitably evolve around EGFR inhibition, and patients with lung cancers eventually relapse. A University of Colorado Cancer Center study published today in the journal Cancer Research details a signaling pathway, known as 'the canonical Wnt pathway', that lung cancer cells use to escape from EGFR-targeted therapy – and suggests that by disrupting this pathway, we could lengthen the usefulness of existing EGFR inhibition therapies. http://medicalxpress.com/news/2012-06-pathway-egfr-inhibitors-lung-cancer.html Cancer Fri, 29 Jun 2012 09:20:03 EST news260180382 Lung cancer is the leading cause of cancer death throughout the world. Standard treatment methods do not usually result in long-term recovery. In addition to the proliferation of the tumour cells, the growth of blood vessels controls tumors development. The blood vessel growth is controlled by several signalling molecules. http://medicalxpress.com/news/2012-05-scientists-aim-lung-tumors.html Cancer Fri, 04 May 2012 14:10:01 EST news255356979 (Medical Xpress) -- Cigarette smoke not only can cause cancer, but it's also responsible for the spread of it, according to research by UC Merced biochemistry professor Henry Jay Forman. http://medicalxpress.com/news/2012-03-cancer.html Cancer Wed, 28 Mar 2012 06:13:14 EST news252133987 Researchers at Winship Cancer Institute are developing a technique to remove cancer cells' defenses against radiation. http://medicalxpress.com/news/2012-03-disabling-cancer-cells-defenses.html Cancer Thu, 15 Mar 2012 14:46:43 EST news251041594 Singapore scientists, headed by Dr. Bing Lim, Associate Director of Cancer Stem Cell Biology at the Genome Institute of Singapore (GIS), a research institute under the umbrella of the Agency for Science, Technology and Research (A*STAR), and Dr Elaine Lim, medical oncologist affiliated with Tan Tock Seng Hospital (TTSH) and National Cancer Centre Singapore (NCCS), have, for the first time, identified a gene responsible for lung cancer.

In mouse lung cancer cells, treatment with silibinin, a major component of milk thistle, removed the molecular billboards that signal these wound-like conditions and so stopped the spread of these lung cancers, according to a recent study published in the journal Molecular Carcinogenesis. http://medicalxpress.com/news/2011-11-thistle-lung-cancer-mice.html Cancer Tue, 15 Nov 2011 15:47:19 EST news240594430 Researchers at the University of Colorado Cancer Center have developed a test that identifies key biomarkers in advanced lung cancer that helped reduce the risk of death by 36 percent over a 30- month period in a recent clinical trial. http://medicalxpress.com/news/2011-10-death-advanced-lung-cancer.html Cancer Tue, 11 Oct 2011 14:27:55 EST news237562066 Several clinical studies have shown that taking the anti-inflammatory drug celecoxib can reduce the risk of developing polyps that lead to colon cancers, at the cost of increasing the risk of heart disease.
