1 Mutant Kras as a Biomarker Plays a Favorable Role in FL118-Induced Apoptosis, Reactive Oxygen Species (ROS) Production and Modulation of Survivin, Mcl-1 and XIAP in Human Bladder Cancer. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
2 Using molecular, cellular, proteomics and animal models, we demonstrated that FL118, an innovative small molecule, is highly effective at killing T24 and UMUC3 high-grade BC cells, which have Hras and Kras mutations, respectively. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
3 Silencing mutant Kras reduced both FL118-induced PARP cleavage and downregulation of survivin, XIAP and Mcl-1 in UMUC3 cells, suggesting mutant Kras is required for FL118 to exhibit higher anticancer efficacy. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
4 Silencing mutant Kras reduced both FL118-induced PARP cleavage and downregulation of survivin, XIAP and Mcl-1 in UMUC3 cells, suggesting mutant Kras is required for FL118 to exhibit higher anticancer efficacy. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
5 Silencing mutant Kras reduced both FL118-induced PARP cleavage and downregulation of survivin, XIAP and Mcl-1 in UMUC3 cells, suggesting mutant Kras is required for FL118 to exhibit higher anticancer efficacy. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
6 Silencing mutant Kras reduced both FL118-induced PARP cleavage and downregulation of survivin, XIAP and Mcl-1 in UMUC3 cells, suggesting mutant Kras is required for FL118 to exhibit higher anticancer efficacy. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
7 Silencing mutant Kras in UMUC3 cells reduced FL118-mediated ROS generation. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
8 Silencing mutant Kras in UMUC3 cell-derived tumors decreases UMUC3 tumor sensitivity to FL118 treatment. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
9 Together, our studies revealed that mutant Kras is a favorable biomarker for FL118 targeted treatment. 7-ethyl-7-hydroxy-10H-1,3-Dioxolo(4,5-g)pyrano(3',4':6,7)indolizino(1,2-b)quinoline-8,11(7H,12H)-dione KRAS proto-oncogene, GTPase Homo sapiens
