The gene-gene interactions underlying CM had not been fully explored. The usual functional model uses substitution of alleles for estimating genetic effects but the estimators are confounded. The NOIA model estimates population effects of alleles and the resulting estimators are orthogonal and no longer confounded. In simulation studies, the NOIA model had higher power for finding interactions and main effects than the usual model. …
Max Mazzone: "For many years the biological processes which lead to the coordinated navigation of blood vessels and nerves have been studied. …
It is not uncommon for influenza viruses to develop genetic mutations that make them less susceptible to anti-flu drugs. However, these mutations usually come at a cost to the virus, weakening its ability to replicate and to spread from one person to another…
Prostate cancer is one of the most common cancers in men, with an estimated 240,000 new cases diagnosed every year – it kills approximately 30,000 men annually. The prostate is a small gland that produces fluid that nourishes and transports sperm…
LDCT has been shown in recent clinical trials to be an effective screening tool in some patients, but some of the tumors it finds may be indolent (slow growing) or clinically insignificant. Overdiagnosis is the detection of a cancer with a screening test that wouldn’t otherwise have become clinically apparent…
The study, to be published Dec. 8 online in the journal Nature Methods, shows that the scientists’ targeted protein-detection approach has the potential to systematically and reliably measure the entire human repertoire of proteins, known as the proteome. …
"These are early results but they are promising, says the study’s lead author, Ayalew Tefferi, M.D. a hematologist at Mayo Clinic. "Some patients in our clinical trial taking imetelstat obtained dramatic responses and there have been some complete responses which is almost unheard of for drug therapy in this disease." Myelofibrosis is a chronic myeloid cancer in which bone marrow cells that produce blood cells develop and function abnormally. The result is the formation of scar tissue in the bone marrow (fibrosis), severe anemia that often requires transfusion, weakness, fatigue and an enlarged spleen and liver…
The journal Blood has published a new study on a drug candidate for multiple myeloma, a form of cancer that affects about one per cent of all tumour patients, with some 600 people a year developing the disease in Sweden. …
Their findings, reported in the Journal of Clinical Oncology, are the first to quantify, in the setting of a clinical trial, the increased risk of prostate cancer development from the protein ERG. Traditional means of determining risk of prostate cancer — blood tests for the protein prostate-specific antigen (PSA) and biopsies — do not always correlate well with the chances of dying from the disease. Decisions on what to do with the results of these tests can be unclear, leaving doctors and patients frustrated and unsure of how to proceed. …
In its earliest stages, breast cancer is confined to the breast and can be treated by surgically removing the cancer cells. As the disease progresses, breast cancer cells may spread to the lymph nodes and then to other areas of the body. "On its pathway to other places in the body, the first place breast cancer typically drains into before metastasizing is the lymph nodes," said Lilian Wang, M.D., assistant professor of radiology at Northwestern University/Feinberg School of Medicine in Chicago, Ill. "When breast cancer has spread into the lymph nodes, the patient is often treated both locally and systemically, with either hormone therapy, chemotherapy, trastuzumab or some combination of these therapies." Historically, healthcare organizations, such as RSNA and the American Cancer Society (ACS), have recommended annual screening with mammography for women beginning at age 40. …
