Blocking Myc proteins stops ovarian cancer cell cycle in its tracks

Ovarian cancer cells are "addicted" to a family of proteins produced by the notorious oncogene, MYC.

Mechanism behind cardiac scarring discovered

In the aftermath of a heart attack, the body's own defenses may contribute to future heart failure. Authors of a new study believe they have identified a protein that plays an important role in a process that replaces dead heart muscle with stiffening scar tissue. The researchers are hopeful that the findings will lead to the development of new therapies to prevent this damage.

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.

Three studies of bioTheranostics molecular breast cancer diagnostics presented at symposium

bioTheranostics, a bioMerieux company that discovers, develops and commercializes new molecular diagnostic tests in oncology, reported today findings from three studies using the company's molecular breast cancer assay to predict risk of disease recurrence in individual patients.

Tau protein expression predicts breast cancer survival in an unexpected way

Expression of the microtubule-binding protein Tau is not a reliable means of selecting breast cancer patients for adjuvant paclitaxel chemotherapy, according to research led by The University of Texas M. D. Anderson Cancer Center.

Promising clinical trial for Progeria "premature aging" disease

One of the fastest translations of a basic research discovery into a promising clinical trial for an "untreatable" and fatal disorder will be discussed publicly for the first time by the key players in this remarkable research story, on Sunday, Dec. 14, at the American Society for Cell Biology (ASCB)'s annual meeting in San Francisco.

Exciting cancer discovery

Metastasis is the ability of cancer cells to spread from a primary site, to form tumours at distant sites.

Early-stage breast cancer patients with HER2 positive tumors at increased risk of recurrence

Early-stage breast cancer patients with HER2 positive tumors one centimeter or smaller are at significant risk of recurrence of their disease, compared to those with early-stage disease who do not express the aggressive protein, according to a study led by researchers at The University of Texas M. D. Anderson Cancer Center.

Possible new therapeutic target for pancreatic cancer

A possible new therapeutic target for pancreatic cancer, the most lethal form of human cancer, has been identified in the proteins whose DNA recipe comes from gene, "Seven-In-Absentia," according to researchers at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Discovery of gene mutation that appears to help prevent heart disease

Researchers at the University of Maryland School of Medicine in Baltimore have discovered a novel gene mutation among the Old Order Amish population that significantly reduces the level of triglycerides in the blood and appears to help prevent cardiovascular disease.

Numbing drugs can have profound and long-term negative effects

A large proteomics study on the brains of newborn mice provides more evidence that numbing drugs often used in obstetric or pediatric medicine can have profound and long-term negative effects, even after minimal exposure.

Food you eat can immediately impact cognitive behavior

A new study from the psychology department at Tufts University shows that when dieters eliminate carbohydrates from their meals, they performed more poorly on memory-based tasks than when they reduce calories, but maintain carbohydrates.

Heart regenerates after infarction

Up until today scientists assumed that the adult heart is unable to regenerate. Now, researchers and cardiologists from the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and the Charité - Universitätsmedizin Berlin (Germany) have been able to show that this dogma no longer holds true.
