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.

Large US study finds never-married adults face higher risk for most major cancers

A large US population-based study found that never-married adults had higher cancer incidence than ever-married adults across most cancer types, with the largest disparities seen in older adults and in Black men. The pattern was especially strong for HPV-related, tobacco-related, and several reproductive cancers, suggesting marital status may act as an important social marker of cancer risk.

OICR funds four Ontario teams to develop next-generation cancer therapies

Better cancer care depends on better treatment options. That's why the Ontario Institute for Cancer Research (OICR) is supporting four Ontario-based research teams working to develop the next generation of cancer therapies that are designed to be more effective at destroying tumors, have reduced side effects, and make cancer less likely to return.

Sponge and sea slug partnership yields a new anticancer molecule with drug design promise

Researchers identified jorumycidine, a new hexacyclic marine alkaloid from the nudibranch Jorunna funebris and its dietary sponge, Haliclona sp., and demonstrated that it exhibits potent nanomolar cytotoxicity against multiple myeloma cells. They also proposed a new biosynthetic route involving cross-species metabolic interplay and an unusual oxazolidine ring that may help stabilize a pharmacologically important scaffold.
