Researchers at Georgetown University Medical Center (GUMC) are voicing alarm that drugs to treat a wide variety of allergies, asthma and autoimmune diseases now in human clinical trials may errantly spur development of breast tumors. http://www.physorg.com/news174804357.html Medicine & Health Thu, 15 Oct 2009 06:00:43 EST news174804357 A new study published by University of Leicester researchers has found "convincing evidence" that cannabis smoke damages DNA in ways that could potentially increase the risk of cancer development in humans. http://www.physorg.com/news164348909.html Medicine & Health Tue, 16 Jun 2009 05:45:28 EST news164348909 Liver cancer is one of the most fatal human malignancies and the third most frequent cause of tumor-related death, about half a million people globally each year. The current methods used to monitor such high-risk groups include ultrasound scans and a test for the presence of a single protein in the blood called alpha-fetoprotein. It is a good indicator of advanced liver cancer, but less able to detect early disease. So it is the most impotent thing is find the changes of biomarker combinations in the early period of diseases, control the key gene in the initial stage of disease and reverse the development of disease. http://www.physorg.com/news164278973.html Medicine & Health Mon, 15 Jun 2009 10:03:12 EST news164278973 You know the guy -- he's your Facebook friend. The one who knows everyone. Secure at the center of a dense web of relationships, he suggests causes and reconnects old friends like a skilled matchmaker. Scientists have known for some time that biological molecules interact with one another in a similarly complex pattern. Now researchers at the Stanford University School of Medicine have determined that hamstringing these molecular powerbrokers is a good way to derail processes such as cancer development. http://www.physorg.com/news163078173.html Medicine & Health Mon, 01 Jun 2009 12:30:11 EST news163078173 (PhysOrg.com) -- University of Cincinnati (UC) cancer cell biologists have identified a distinct gene linked to increased lung cancer susceptibility and development. They say this gene -known as RGS17 -could result in a genetic predisposition to develop lung cancer for people with a strong family history of the disease. http://www.physorg.com/news159022902.html Medicine & Health Wed, 15 Apr 2009 14:02:13 EST news159022902 Scientists at The University of Texas M. D. Anderson Cancer Center have discovered a gene that protects PTEN, a major tumor-suppressor that is reduced but rarely mutated in about half of all breast cancers. http://www.physorg.com/news158244619.html Medicine & Health Mon, 06 Apr 2009 13:51:15 EST news158244619 Chronic human papilloma virus (HPV)-infections can lead to cellular changes in the cervix that can be a pre-stage to cervical cancer. Surgical treatment of these pre-stages gives an increased risk of preterm birth in subsequent pregnancies. As the HPV-vaccine can prevent pre-stages of cervical cancer, it may therefore reduce the number of preterm births. A new Norwegian study has calculated the benefits of HPV-vaccination. http://www.physorg.com/news156513765.html Medicine & Health Tue, 17 Mar 2009 13:05:52 EST news156513765 Researchers at the Mayo Clinic campus in Florida have found that a drug now being tested to treat a range of human cancers significantly inhibited colon cancer development in mice. Because the agent appears to have minimal side effects, it may represent an effective chemopreventive treatment in people at high risk for colon cancer, the investigators say. http://www.physorg.com/news153631834.html Medicine & Health Thu, 12 Feb 2009 03:32:47 EST news153631834 Researchers from the University of Michigan Comprehensive Cancer Center have identified a panel of small molecules, or metabolites, that appear to indicate aggressive prostate cancer. http://www.physorg.com/news153580723.html Medicine & Health Wed, 11 Feb 2009 13:19:24 EST news153580723 (PhysOrg.com) -- Researchers long ago established a link between inflammation, cancer and the compound nitric oxide, which may be produced when the immune system responds to bacterial infections, including those of the colon. However, the exact nature of the relationship was unknown -- until now. http://www.physorg.com/news151680304.html Medicine & Health Tue, 20 Jan 2009 13:25:20 EST news151680304 Cincinnati scientists have identified a new biomarker that could help predict a person's risk of developing colon cancer and how aggressive it may become. http://www.physorg.com/news151320742.html Medicine & Health Fri, 16 Jan 2009 09:32:22 EST news151320742 While examining patterns of DNA modification in lung cancer, a team of international researchers has discovered what they say is a surprising new mechanism. They say that "silencing" of a single gene in lung cancer led to a general impairment in genome-wide changes in cells, contributing to cancer development and progression. http://www.physorg.com/news149924210.html Medicine & Health Wed, 31 Dec 2008 05:36:50 EST news149924210 Researchers at the University of Southern California (USC) have found that inactivating a specific biomarker for aggressive prostate cancer blocks the development of prostate cancer in animal models. http://www.physorg.com/news146767721.html Medicine & Health Mon, 24 Nov 2008 16:48:41 EST news146767721 New research strongly suggests that a mix of preventative agents, such as those found in concentrated black raspberries, may more effectively inhibit cancer development than single agents aimed at shutting down a particular gene. http://www.physorg.com/news139054245.html Medicine & Health Wed, 27 Aug 2008 11:10:45 EST news139054245
