“…In PanC1, certain membrane proteins appear to be down-regulated upon nicotine treatment, such as those involved in cell adhesion and transmembrane/ion transport as well as oxidative phosphorylation [41]. In HPNE, up-regulated proteins included those involved in cytokine response, steroid biosynthesis, cell migration, extracellular structure organization and the JAK/STAT signaling pathway, all of which have been implicated as cellular responses to nicotine [17, 20, 42]. Cell division, ribosomes, and certain cell cycle proteins trended down in HPNE and up in PanC1, emphasizing the different effects that nicotine has on the cell lines.…”
