1 Nicotine induces cell survival and chemoresistance by stimulating Mcl-1 phosphorylation and its interaction with Bak in lung cancer. Nicotine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
2 Our previous data found that nicotine promotes cell survival in lung cancer by affecting the expression of antiapoptotic protein Mcl-1, suggesting that the Mcl-1 may be a therapeutic target for patients with lung cancer. Nicotine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
3 Our previous data found that nicotine promotes cell survival in lung cancer by affecting the expression of antiapoptotic protein Mcl-1, suggesting that the Mcl-1 may be a therapeutic target for patients with lung cancer. Nicotine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
4 In this study, we found that the effects of drug resistance on nicotine-induced lung cancer cell lines were shown to influence the phosphorylation of Mcl-1. Nicotine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
5 Moreover, nicotine induces Mcl-1 phosphorylation exclusively at the T163 site, which results in enhancement of the antiapoptotic activity of Mcl-1 and increased cell survival. Nicotine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
6 Moreover, nicotine induces Mcl-1 phosphorylation exclusively at the T163 site, which results in enhancement of the antiapoptotic activity of Mcl-1 and increased cell survival. Nicotine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
7 Meanwhile, nicotine can reduce the sensitivity of H1299 cells to CDDP via enhancement of the binding of Mcl-1 to Bak, which inhibits the proapoptotic effect of Bak and ultimately leads to increased survival and drug resistance of lung cancer cells. Nicotine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
8 Thus, nicotine-induced cell survival and chemoresistance may occur in a mechanism by stimulating Mcl-1 phosphorylation and its interaction with Bak, which may contribute to improving the efficacy of chemotherapy in the treatment of human lung cancer. Nicotine MCL1 apoptosis regulator, BCL2 family member Homo sapiens
