DNA in Blood Tracks Cancer Development and Response

Circulating tumor DNA analysis can be used to track tumor burden and analyze cancer genomes noninvasively, but the extent to which it represents metastatic heterogeneity is unknown.  More...

Blood Test Increases Accuracy in Prenatal Testing

A simple, accurate and low risk blood test can detect fetal blood group, sex, and genetic conditions in unborn babies and the DNA test is inexpensive and is noninvasive, as opposed to the traditional amniocentesis test that involves a needle and carries a minor risk of miscarriage.   More...

Genetic Risk Marker Found for Late-Life Depression

The epsilon 4 allele of the apolipoprotein gene has been associated with atherosclerosis as well as cardiovascular and cerebrovascular disease but it is less clear whether there is also an association with geriatric depression.  More...

Blood Samples Analysis Monitors Colorectal Cancer Chemotherapy Response

Circulating cell-free DNA may be collected from plasma of colorectal cancer patients and represents a less invasive, less costly approach to tracking biomarkers of interest longitudinally and at progression.  More...

Rapid Ebola Virus Detection Assay Evaluated

Ebolavirus infection is mainly diagnosed by various in-house and commercial real-time reverse transcriptase polymerase chain reaction assays used in up to 38 laboratories implemented at or close to Ebola treatment centers in West Africa.  More...

Cancer DNA in Blood Helps Personalize Liver Cancer Treatment

Liver cancer tumor specimens are difficult and sometimes dangerous to obtain, and noninvasive methods are required to assess cancer progression and characterize underlying genomic features.  More...

Predisposing Gene Associated With Cowden Syndrome

A new gene has been discovered that is associated with Cowden syndrome, an inherited condition that carries high risks of thyroid, breast, and other cancers, and a subset of non-inherited thyroid cancers.  More...
