New ‘lab-on-a-chip’ could revolutionize early diagnosis of cancer

New ‘lab-on-a-chip’ could revolutionize early diagnosis of cancer

Scientists have been laboring to detect cancer and a host of other diseases in people using promising new biomarkers called “exosomes.” Indeed, Popular Science magazine named exosome-based cancer diagnostics one of the 20 breakthroughs that will shape the world this year. Exosomes could lead to less invasive, earlier detection of cancer, and sharply boost patients’ odds of survival Continue reading

New blood test determines whether you have or are likely to get cancer

New blood test determines whether you have or are likely to get cancer

A new research report published in the October 2014 issue of The FASEB Journal may make the early detection of cancer as easy as a simple blood test. This test, called the “lymphocyte genome sensitivity” (LGS) test, could not only detect some cancers earlier than ever before, but it may eliminate the need for some types of biopsies, as well as identify those more likely to develop cancer in the future. “The test could allow earlier cancer detection, so helping to save peoples’ lives,” said Diana Anderson, a researcher involved in the work from the School of Life Sciences at the University of Bradford in West Yorkshire, United Kingdom Continue reading

Scientists identify which genes are active in muscles of men, women

Scientists identify which genes are active in muscles of men, women

If you want your doctor to know what goes wrong with your muscles because of age, disease or injury, it’s a good idea to know what “normal” actually is. Continue reading

Adolescent exposure to THC may cause immune systems to go up in smoke

Adolescent exposure to THC may cause immune systems to go up in smoke

When it comes to using marijuana, new research, involving mice and published in the October 2014 issue of the Journal of Leukocyte Biology , suggests that just because you can do it, doesn’t mean that you should. That’s because a team of Italian scientists have found that using marijuana in adolescence may do serious long-term damage to the immune system. This damage may result in autoimmune diseases and chronic inflammatory diseases, such as multiple sclerosis, inflammatory bowel disease and rheumatoid arthritis in adulthood. Continue reading

Genetic modifier affects colon tumor formation

Genetic modifier affects colon tumor formation

Unexpected results from an ongoing experiment in the lab of Kristi Neufeld, co-leader of the Cancer Biology Program at the University of Kansas Cancer Center, led to a potentially important discovery that could have an effect on how cancer researchers test anti-cancer therapies in mice as well as possibly prevent colon cancer in people. Neufeld, associate professor in the Department of Molecular Biosciences, studies the adenomatous polyposis coli protein, which protects against colon cancer. Continue reading

Early sign of pancreatic cancer identified by researchers

Early sign of pancreatic cancer identified by researchers

Scientists at Dana-Farber Cancer Institute, the Massachusetts Institute of Technology, and other institutions have discovered a sign of the early development of pancreatic cancer – an upsurge in certain amino acids that occurs before the disease is diagnosed and symptoms appear. The research is being published online today by the journal Nature Medicine . Although the increase isn’t large enough to be the basis of a new test for early detection of the disease, the findings will help researchers better understand how pancreatic cancer affects the rest of the body, particularly how it can trigger the sometimes deadly muscle-wasting disease known as cachexia.

How physical exercise protects the brain from stress-induced depression

How physical exercise protects the brain from stress-induced depression

Physical exercise has many beneficial effects on human health, including the protection from stress-induced depression. However, until now the mechanisms that mediate this protective effect have been unknown Continue reading

New protein players found in key disease-related metabolic pathway

New protein players found in key disease-related metabolic pathway

To coordinate their size and growth with current environmental conditions, cells rely on the mechanistic target of rapamycin complex 1 (mTORC1) pathway, which senses cellular stresses, growth factors, and the availability of nutrients, such as amino acids and glucose. Continue reading
