Researchers developed a new laboratory method to improve genetic diagnostic tests for colon cancer and inherited diseases. The technique detects defective genes that are masked when one copy is normal, increasing the accuracy of testing. This could lead to increased detection rates for many genetic diseases.
Scientists from the University of Wisconsin-Madison have developed a new surface chemistry that simplifies DNA computing and enables scaling up to tackle complex problems. This breakthrough demonstrates DNA computing's potential to surpass conventional computers in information storage and processing capabilities.
Researchers at Cold Spring Harbor Laboratory identified eight previously unknown genes associated with prostate cancer. The study's 'guilt-by-association' method used statistical analysis to link genes mimicking PSA activity to the disease.
A recent Yale Cancer Center study reveals that many experienced cancer genetic counselors would pursue genetic testing for BRCA or HNPCC mutations despite concerns about discrimination. However, the majority would not bill insurance companies or use aliases, and would only share test results with physicians.
A team of researchers has identified a genetic link on mouse Chromosome 19 that controls inherited susceptibility to testicular cancer. The discovery uses a new genetic technique called chromosome substitution, which may lead to improved understanding and treatment options for the disease.
A NIAAA-led study confirms that environmental factors can significantly impact the behavior of genetically identical mice, challenging traditional assumptions about genetic determinism. The research highlights the need for laboratories to replicate tests locally and standardize behavioral tests to minimize environmental influences.
Campylobacter is a leading cause of food poisoning, but lacked a reliable test until now. Researchers have developed a quick DNA test that can identify the bacterium in eight hours, and a scanner to detect faecal contamination on meat.
Researchers found that combining the Apolipoprotein E (ApoE) genetic test with clinical examinations significantly improved diagnosis accuracy for Alzheimer's disease. The study showed a 45% to 16% reduction in false positive diagnoses, emphasizing the potential of ApoE testing as a diagnostic aid.
A study found that 81% of women at risk for breast cancer planned to undergo genetic testing, driven by perceived benefits such as increased breast self-examination and better treatment options. Counseling is crucial to help them make informed decisions and manage potential psychological reactions.
Virginia Tech Professor Doris Teichler Zallen explains the options, limitations, and problems of genetic testing for disorders like Alzheimer's, breast cancer, and muscular dystrophy. She highlights the need for informed consumers to weigh the benefits and risks of testing against their personal values and circumstances.
A recent study by Johns Hopkins Medicine reveals that many patients undergoing gene testing for cancer susceptibility are not adequately informed about the test's benefits and limitations. The survey found that only 19% of patients received genetic counseling prior to testing, and 17% provided written informed consent.
The new test developed by Prof. Roald Nezlin of the Weizmann Institute solves a problem with standard tests by measuring the quantity of DNA in harmful complexes, indicating effective treatment. This approach could also be used to measure antibody complexes involved in other autoimmune diseases.
Researchers at Duke University Medical Center found that testing for a specific gene type can accurately diagnose Alzheimer's disease in most patients. The study showed that 100% of patients with the Alzheimer's susceptibility gene had the disease's telltale neurofibrillary plaques and tangles.
