Abstract:Despite the ability of chemotherapy (and/or radiation) to eliminate the majority of tumor cells, some residual surviving cells may be able to escape cell death by entering into a prolonged growth arrest from which they can ultimately re-emerge and proliferative . In this study, we evaluated two mechanisms, autophagy and senescence, that in theory could allow tumor cells to escape apoptotic cell death, and which therefore might be responsible for cancer recurrence. 4T1 murine breast cancer cells exposed to the … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
