Nicotine 0-8 MCL1 apoptosis regulator, BCL2 family member Homo sapiens 34-39 31956373-1 2020 Background: Nicotine contributes to development of human lung cancer and chemoresistance through activation of myeloid cell leukemia-1 (Mcl-1). Nicotine 12-20 MCL1 apoptosis regulator, BCL2 family member Homo sapiens 111-134 31956373-1 2020 Background: Nicotine contributes to development of human lung cancer and chemoresistance through activation of myeloid cell leukemia-1 (Mcl-1). Nicotine 12-20 MCL1 apoptosis regulator, BCL2 family member Homo sapiens 136-141 31956373-3 2020 Therefore, we examined the STAT3 cascade in nicotine regulation of Mcl-1 transcription in human lung cancer cells. Nicotine 44-52 MCL1 apoptosis regulator, BCL2 family member Homo sapiens 67-72 31956373-4 2020 Methods: The effects of nicotine on the expression of STAT3 and Mcl-1 were determined using western blot. Nicotine 24-32 MCL1 apoptosis regulator, BCL2 family member Homo sapiens 64-69 31956373-7 2020 Results: STAT3 was constitutively activated (i.e., tyrosine-phosphorylated, serine-phosphorylated and nuclear translocation), meanwhile the expression and transcriptional activity of Mcl-1 were up-regulated in lung cancer cells following treatment with nicotine. Nicotine 253-261 MCL1 apoptosis regulator, BCL2 family member Homo sapiens 183-188 31956373-9 2020 Deleted mutagenesis of a putative STAT3 consensus binding sequence decreased Mcl-1 promoter activity and eliminated the increase of Mcl-1 promoter activity induced by nicotine. Nicotine 167-175 MCL1 apoptosis regulator, BCL2 family member Homo sapiens 132-137 31956373-12 2020 Conclusions: We have demonstrated that nicotine induces up-regulation of Mcl-1 through STAT3, which process may be independent on JAKs and not only dependent on the phosphorylation of Y705. Nicotine 39-47 MCL1 apoptosis regulator, BCL2 family member Homo sapiens 73-78
