‘Basal-like’ breast cancer does not originate from basal stem cells

New research uncovers a case of mistaken identity that may have a significant impact on future breast cancer prevention and treatment strategies. The study, published by Cell Press in the September 3rd issue of the journal Cell Stem Cell, suggests that despite their “stem cell-like” characteristics, most aggressive breast tumors are not derived from normal mammary gland stem cells.

Using readily available computer programs, researchers have developed a system to identify genes that will be useful in the classification of breast cancer. The algorithm, described in BioMed Central’s open access Journal of Experimental & Clinical Cancer Research will enable researchers to quickly generate valuable gene signatures without specialized software or extensive bioinformatics training.

OAK BROOK, Ill. Some nuclear-based breast imaging exams may increase a woman’s risk of developing radiation-induced cancer, according to a special report appearing online and in the October issue of Radiology. However, the radiation dose and risk from mammography are very low.
Protein made by breast cancer gene purified

A key step in understanding the origins of familial breast cancer has been made by two teams of scientists at the University of California, Davis. The researchers have purified, for the first time, the protein produced by the breast cancer susceptibility gene BRCA2 and used it to study the oncogene’s role in DNA repair.
Researchers identify breast cancer culprits

Scientists have discovered an accomplice in breast cancer a master control switch with the power to set off a cascade of reactions orchestrated by a cancer-causing gene (or oncogene) named Wnt1. This executive molecule and its modus operandi are reported in back-to-back papers featured on the cover of the August 15 issue of Cancer Research.

Researchers at the University of Gothenburg, Sweden, have for the first time identified 12 genes that could be associated with aggressive breast tumours. The discovery could result in more reliable prognoses and better treatment strategies for patients.

Cedars-Sinai participates in international study suggesting that the underlying genetic weakness of cancer, not the organ of origin, is key to effective therapy
LOS ANGELES (Aug. 11, 2010) Understanding the underlying genetic weakness of certain types of cancer may lead to targeted therapy and provide the key to effective treatment, a new study suggests. An international consortium of researchers has shown that an investigational drug, Olaparib, can reduce the size of tumors in women with advanced hereditary ovarian cancer with BRCA gene mutations.

Lasers illuminate women’s health in inaugural open-access journal Biomedical Optics Express
WASHINGTON, August 2 A new study of breast cancer survivors may help physicians ease a common side effect of cancer treatments. The collaborative research by Eva Sevick, Ph.D., Director of the Center for Molecular Imaging at the University of Texas Health Science Center in Houston (UTHSC), and Caroline Fife, M.D., Director of the Memorial Herman Wound Care Clinic at UTHSC, could bring relief to millions.
Genetic risk score associated with breast cancer risk; predictive of type of disease

Women with higher risk scores that consisted of having certain genetic variants most strongly linked to breast cancer had an associated higher risk of breast cancer, with these scores also highly predictive of estrogen receptor-positive disease, according to a study in the July 28 issue of JAMA.

Study finds that the GRB7 gene drives an aggressive form of the disease
PORTLAND, Ore. Oregon Health & Science University Knight Cancer Institute researchers found that the GRB7 gene drives an aggressive form of breast cancer and acts independently of the HER-2 gene, known to be a stimulator of breast cancer growth. Isolating the role of this gene could ultimately help fine-tune a patient’s treatment and enable physicians to provide a more accurate prognosis.
