34681897-12	2021	Cotreatment with tamoxifen, an estrogen receptor inhibitor, increased the sensitivity to doxorubicin, which decreased the colony formation of P53(+) U2OS cells.	Doxorubicin	89-100	tumor protein p53	Homo sapiens	142-145	
34681897-13	2021	Cell cycle arrest in the S phase was observed in P53(+) U2OS cells cotreated with low doses of doxorubicin and tamoxifen, while increased levels of apoptosis factors indicated cell death.	Doxorubicin	95-106	tumor protein p53	Homo sapiens	49-52
