Genetic ID of marker in lymph nodes may be linked to colorectal cancer recurrence risk

A preliminary report suggests that genetic testing may help identify a marker in lymph nodes that is associated with an increased risk of colorectal cancer recurrence among patients in whom conventional testing indicates that those lymph nodes show no evidence of cancer spread, according to a study in the February 18 issue of JAMA.

Presence of a biomarker in regional lymph nodes predicts disease recurrence in colorectal cancer

Findings published in the Journal of the American Medical Association by researchers at Thomas Jefferson University show that the presence of a biomarker in regional lymph nodes is an independent predictor of disease recurrence in patients with colorectal cancer.

Microfluidic devices capture and analyze single cancer cells

One of the grand goals in nanotechnology is to develop a single microfluidic device that integrates all of the components needed to perform polymerase chain reaction (PCR)-based nucleic acid analyses. Experts predict that such a device would enable researchers to develop rapid assays for cancer and other life-threatening diseases while a patient is in the doctor's office.

Biologist finds plant polymerases IV and V are really variants of polymerase II

It's a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase II, an essential enzyme of all eukaryotic organisms, including humans.

Scientists isolate genes that made 1918 flu lethal

By mixing and matching a contemporary flu virus with the "Spanish flu" - a virus that killed between 20 and 50 million people 90 years ago in history's most devastating outbreak of infectious disease - researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.
