1 Furthermore, we found that TopBP1, which we previously showed was involved in doxorubicin resistance through upregulation of aberrant p53, was involved in calcein-AM-mediated increased doxorubicin sensitivity. calcein AM DNA topoisomerase II binding protein 1 Homo sapiens
2 Calcein-AM repressed the expression of TopBP1, which resulted in reduced expression of aberrant p53 and disrupted the antiapoptotic activity mediated by the TopBP1/mutp53 pathway in NSCLC. calcein AM DNA topoisomerase II binding protein 1 Homo sapiens
3 Calcein-AM repressed the expression of TopBP1, which resulted in reduced expression of aberrant p53 and disrupted the antiapoptotic activity mediated by the TopBP1/mutp53 pathway in NSCLC. calcein AM DNA topoisomerase II binding protein 1 Homo sapiens
4 Together, our findings show that calcein-AM, the cell-permeable derivative of calcein, exerts significant antitumor effects in NSCLC, and can enhance the antitumor effect of doxorubicin by regulating the TopBP1/mutp53 pathway. calcein AM DNA topoisomerase II binding protein 1 Homo sapiens
