GUMC researchers find gene inactivated in two aggressive cancers

Researchers at Georgetown University Medical Center have found a gene they say is inactivated in two aggressive cancers - malignant melanoma, a form of skin cancer, and glioblastoma multiforme, a lethal brain tumor.

New understanding of mechanism that regulates DNA methylation

Researchers in a University of Oregon lab have shed more light on the mechanism that regulates DNA methylation, a fundamental biological process in which a methyl group is attached to DNA, the genetic material in cells of living organisms.

Having dense breasts increases breast cancer risk

Having dense breasts - areas that show up light on a mammogram - is strongly associated with increased breast cancer risk, but "why" remains to be answered.

Researchers identify how key mutations occur in human lymphomas

Researchers at the Keck School of Medicine of the University of Southern California (USC) have explained how certain key mutations occur in human lymphomas - a process that has, until now, remained a mystery.

Timothy syndrome provides clues about enzyme role in arrhythmias

A University of Iowa study provides insight into a calcium-sensing enzyme already known to play a role in irregular heartbeats and other critical functions.

Researchers find tamoxifen's power comes from endoxifen

Mayo Clinic researchers have discovered that a chemical known as endoxifen appears to be the primary metabolite responsible for the effectiveness of tamoxifen in treating breast cancer, and that it works against cancer in an entirely unexpected way.

Enzyme that mutates antibodies also targets cancer-causing gene

The human immune system is in a perpetual state of self-experimentation. It expertly mutates and shuffles the DNA of its own cells to evolve new defenses against the vast array of microbes that try to invade our bodies.

Trial looks at new treatment for solid cancer tumors and non-Hodgkin's lymphoma

Researchers at The Cancer Institute of New Jersey (CINJ) have opened a clinical trial, which aims to evaluate a new treatment for solid cancer tumors and non-Hodgkin's lymphoma (NHL) in combination with a chemotherapy agent called cyclophosphamide.

Enzyme that mutates antibodies also targets a cancer-causing oncogene

Rockefeller University scientists have discovered that the same enzyme that enables the immune system's defensive creativity is also responsible for a particular genetic malfunction - a translocation of one piece of DNA to the wrong chromosome - that causes Burkitt's lymphoma.

Researchers find inherited genetic variation in nicotine addiction

A new study from the Abramson Cancer Center and Department of Psychiatry in the University of Pennsylvania School of Medicine shows that smokers who carry a particular version of a gene for an enzyme that regulates dopamine in the brain may suffer from concentration problems and other cognitive deficits when abstaining from nicotine - a problem that puts them at risk for relapse during attempts to quit smoking.
