These data, on one hand assessed that HER2+ breast tumor cells are less sensitive to DADS than other breast tumor phenotypes, [41,42] and other tumor cell models [64,65,66], on the other hand, revealed that their invasive potential increases when treated with DADS at concentrations useful for reducing invasiveness in other tumor models [41,42,67], underscoring, for the first time, a potential adverse effect of the use of garlic compounds on breast cancer cells. The gene discussed is ERBB2; the disease is breast cancer.
