Assessment of global proteome in LNCaP cells by 2D-RP/RP LC–MS/MS following sulforaphane exposure
The phytochemical sulforaphane can induce cell cycle arrest and apoptosis in metastatic prostate cancer cells, though the mechanism of action is not fully known. We conducted a global proteome analysis in LNCaP metastatic prostate cancer cells to characterize how global protein signature responds to sulforaphane. We conducted parallel analyses to evaluate semi-quantitative 1-dimensional versus 2-dimensional liquid chromatography tandem mass spectrometry (LC–MS/MS) and their utility in characterizing whole cell lysate. We show that 2-dimensional LC–MS/MS can be a useful tool for characterizing global protein profiles and identify TRIAP1 as a novel regulator of cell proliferation in LNCaP metastatic prostate cancer cells.
