Blood Test for Colorectal Cancer Recurrence Proves Highly Sensitive

When diagnosed early, before cancer has spread, the relative five-year survival rate for colorectal cancer (CRC) is 90%, but only approximately four out of 10 CRC cases are detected early. More...

DNA-Based Analysis Detects Group A Streptococcus

As an exclusively human pathogen, Group A Streptococcus (GAS; Streptococcus pyogenes) is spread in the community through direct human-to-human transmission and GAS can also colonize a healthy host without any apparent clinical signs or symptoms. More...

Gene Activity Mapping Points to Two Subtypes of Crohn's Disease

Gene activity studies have found that there are two clinically relevant forms of Crohn's disease that are defined by molecular signatures that are not linked to tissue sampling location, patient age, or treatment status. More...

Liquid Biopsy Tests Identified Cell-Free Tumor DNA Mutations

The feasibility of using cell-free circulating tumor DNA (ctDNA) next-generation sequencing (NGS) from liquid biopsies as a complement or alternative to tissue NGS has been evaluated. More...

Simple Blood Test Vastly Improves Severe Liver Disease Detection

A new non-invasive method of predicting the risk of developing a severe form of liver disease could ensure patients receive early and potentially life-saving medical intervention before irreversible damage is done. More...

(B) Chimeric RNAs act as scaffolds to bring two genomic loci into proximity, which might promote breakage and fusion between the two gene loci (Photo courtesy of the University of Virginia).

Strange Chimeras Defy Scientific Understanding of Human Genetics

The human genome is far more complex than thought, with genes functioning in an unexpected fashion that scientists have wrongly assumed must indicate cancer as gene fusions and their encoded products fusion ribonucleic acids (RNAs) and proteins are viewed as one of the hallmarks of cancer. More...

New Genetic Links Identified for Heart Disease Risk Factors

Genetics have been implicated in cardiovascular and blood diseases for some time, however as these are complex diseases, it is extremely difficult to find specific genetic causes, but large scale genomic datasets can be used to help identify potential novel biological targets for studying cardiovascular and other diseases.
