Could Alpha-2 Integrin be a Protein Predictor of Tumor Spread?
Researchers have generated data that lead them to suggest that decreased expression of the protein alpha-2 integrin is predictive of tumor dissemination to distant sites and decreased survival in individuals with either breast or prostate cancer. [Press release from Medical News Today discussing online prepublication in the Journal of Clinical Investigation]
Insulin Levels Found to Affect Breast Cancer Survival
Women treated for breast cancer who have elevated levels of circulating insulin face substantially higher mortality rates than their peers with lower levels, a new study has found. [Press release from the Yale School of Public Health discussing online prepublication in the Journal of Clinical Oncology]
Obese Women with ER-Positive/HER2-Negative Breast Cancer Have Poorer Survival Rates
Obesity was associated with worse overall and disease-free survival in women with operable breast cancer treated with adjuvant chemotherapy, but for the first time, researchers observed this finding in only a specific subset of patients – those with estrogen receptor (ER)-positive/HER2-negative disease. [Press release from the American Association for Cancer Research discussing data presented at the 33rd Annual Cancer Therapy & Research Center-AACR San Antonio Breast Cancer Symposium]
Estrogen Alone Is Effective for Reducing Breast Cancer Risk
While endogenous estrogen does have a well-known carcinogenic impact, hormone replacement therapy utilizing estrogen alone (the exogenous estrogen) provides a protective effect in reducing breast cancer risk, according to study.

LABORATORY RESEARCH
The Alpha2Beta1 Integrin Is a Metastasis Suppressor in Mouse Models and Human Cancer
Here, researchers have demonstrated that the alpha2beta1 integrin suppresses metastasis in a clinically relevant spontaneous mouse model of breast cancer. [J Clin Invest]
14-3-3(Sigma) Exerts Tumor Suppressor Activity Mediated by Regulation of COP1 Stability
COP1 is a p53-targeting E3 ubiquitin ligase that is downregulated by DNA damage through mechanisms that remain obscure. Here, researchers report that COP1 is not downregulated following DNA damage in 14-3-3(sigma) null cells, implicating 14-3-3(sigma) as a critical regulator in the response of COP1 to DNA damage. [Cancer Res]
Effect of Maternal and Postweaning Folic Acid Supplementation on Mammary Tumor Risk in the Offspring
The findings suggest that a high intrauterine and postweaning dietary exposure to folic acid may increase the risk of mammary tumors in the offspring. Further, they suggest that this tumor-promoting effect may be mediated in part by altered DNA methylation and DNA methyltransferase activity. [Cancer Res]
The Integrin Alpha(v)Beta(3-5) Ligand MFG-E8 is a p63/p73 Target Gene in Triple Negative Breast Cancers but Exhibits Suppressive Functions in ER+ and erbB2+ Breast Cancers
Researchers identified down-regulation of milk fat globule-EGF factor 8 (MFG-E8) as a contributor to breast cancer progression using microarray analysis of laser capture microdissected tissues. [Cancer Res]
Combining Epitope-Distinct Antibodies to HER2: Cooperative Inhibitory Effects On Invasive Growth
Researchers previously reported that combinations of antibodies directed at non-overlapping epitopes of HER2 are endowed with enhanced antitumor effects, probably due to accelerated receptor degradation. Here, researchers extend these observations to three-dimensional mammary cell models, and compare the effects of single monoclonal antibodies with the effects of antibody combinations. [Oncogene]
Transforming Growth Factor-Beta Regulates the Sphere-Initiating Stem Cell-Like Feature in Breast Cancer through miRNA-181 and ATM
In this study, researchers observed that exposure to transforming growth factor-beta increased the population of breast cancer cells that can form mammospheres in suspension, a feature endowed by stem cells. [Oncogene]
Associations of Insulin Resistance and Adiponectin with Mortality in Women with Breast Cancer
Here, researchers evaluate whether low levels of adiponectin and a greater level of insulin resistance are associated with breast cancer mortality and all-cause mortality. [J Clin Oncol]
Loss of Phosphatase and Tensin Homolog or Phosphoinositol-3 Kinase Activation and Response to Trastuzumab or Lapatinib in Human Epidermal Growth Factor Receptor 2-Overexpressing Locally Advanced Breast Cancers
Researchers evaluated the effect of trastuzumab or lapatinib in three HER2-overexpressing cell lines. They confirmed the in vitro observations in two neoadjuvant clinical trials in patients with HER2 overexpression. [J Clin Oncol]
