Breast Cancer

Breast cancer is cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.

HER-2 Positive Breast Cancer

Human epidermal growth factor receptor 2 (HER2) is a gene that can play an important role in the development of some types of breast cancer. This gene is also sometimes referred to as Erc-B2 receptor tyrosine kinase 2 (ERBB2). This gene is involved in the production of HER2 proteins, which are present on breast cells as receptors to control the growth, division, and repair of the cells.

LIG1 loss reveals new treatment strategy for aggressive breast cancer

Loss of one copy of the DNA Ligase I (LIG1) gene in triple-negative breast cancers (TNBC) with TP53 mutations confers resistance to chemotherapy, but researchers at Baylor College of Medicine and collaborating institutions have identified a vulnerability in these cells and used it to their advantage.

New model improves short- and long-term disease risk prediction

Researchers developed ALADYNOULLI, a Bayesian generative model that combines longitudinal health records, age, and polygenic risk to identify reproducible disease signatures across more than 683,000 participants. In UK Biobank testing, the framework achieved stronger short- and long-term risk discrimination than established clinical scores while revealing disease subgroups and genetic associations.

Targeted nanoparticles destroy tumor cells by triggering cuproptosis

A promising cancer treatment strategy called cuproptosis, which uses copper-dependent cell death to eliminate tumor cells, faces a major challenge: many approaches require adding external copper, potentially increasing toxicity beyond the tumor.

Breast and prostate cancer survival worsens with metabolic syndrome

A SEER-Medicare analysis of more than 200,000 adults aged 66 and older found that metabolic syndrome was associated with about twice the adjusted hazard of death from any cause after breast or prostate cancer. The condition was also linked to higher cancer-specific, cardiovascular-specific, and liver-failure-specific mortality, although the observational design prevents causal conclusions.
