Abstract
After arriving in a secondary site metastatic cells either begin proliferating, undergo apoptosis or remain as solitary dormant cells. The process of metastasis, although dangerous, is extremely inefficient with the majority of the cells undergoing apoptosis and thus becoming clinically irrelevant. Of the cells that begin proliferating, the few that make it past the micrometastasis stage may be of immediate clinical relevance. Dormant cells, while not of immediate clinical concern, are believed to be at least in part responsible for cancer recurrence that can occur decades after apparently successful initial treatment. Dormant solitary cells are different from “dormant” micrometastases, in which active proliferation is balanced by apoptosis. The mechanisms of cell cycle regulation and the function of the molecules regulating this process are well understood. However, there is relatively little known about the mechanisms controlling cell cycle regulation and dormancy of solitary metastatic cells. There are...
