Etoposide 567-576 tyrosyl-DNA phosphodiesterase 1 Homo sapiens 0-4 23605487-6 2010 The specific topoisomerase poisons camptothecin and etoposide caused comparable effects, underlining that TDP1 plays an important role in the repair of topoisomerase-mediated DNA damage. Etoposide 52-61 tyrosyl-DNA phosphodiesterase 1 Homo sapiens 106-110 26421495-4 2015 We found that TDP1kd cells are hypersensitive to etoposide (ETO). Etoposide 49-58 tyrosyl-DNA phosphodiesterase 1 Homo sapiens 14-18 26421495-4 2015 We found that TDP1kd cells are hypersensitive to etoposide (ETO). Etoposide 60-63 tyrosyl-DNA phosphodiesterase 1 Homo sapiens 14-18 26421495-5 2015 Moreover, we established in a chromatin context that following treatment with ETO, TDP1kd cells accumulate increased amounts of Top2alpha cleavage complexes, removing them with an altered kinetics. Etoposide 78-81 tyrosyl-DNA phosphodiesterase 1 Homo sapiens 83-87 26421495-6 2015 We also showed that TDP1 depleted cells accumulate increased gammaH2AX and pS296Chk1 signals following treatment with ETO. Etoposide 118-121 tyrosyl-DNA phosphodiesterase 1 Homo sapiens 20-24 26421495-10 2015 Finally, micronucleus analyses following ETO treatment revealed a higher frequency of micronucleus containing gammaH2AX signals on TDP1kd cells. Etoposide 41-44 tyrosyl-DNA phosphodiesterase 1 Homo sapiens 131-135 21843105-5 2011 Tdp1 inhibitors should synergize not only with Top1-targeting drugs (camptothecins, indenoisoquinolines), but also with bleomycin, topoisomerase II (Top2) inhibitors (etoposide, doxorubicin) and DNA alkylating agents. Etoposide 167-176 tyrosyl-DNA phosphodiesterase 1 Homo sapiens 0-4
