Abstract:
OBJECTIVE:To explore the mechanism of paclitaxel on the protein expression of human cervical carcinoma cell line HCE1.
METHODS:The total proteins extracted from paclitaxel-treated HCE1 cells were analyzed by 2-dimensional gel electrophoresis (2-DE), and compared with those from untreated HCE1 cells. The differential proteins were identified by mass spectrometry. Western blot was used to determine the differential expression levels of the 2 proteins.
RESULTS:At 24 hour after paclitaxel (0.05 mumol/L) treatment, 2-DE images of paclitaxel-treated and paclitaxel-untreated cells were analyzed. Forty-two differential proteins were found. Twenty-one differential proteins among 42 proteins were analyzed by mass spectrometry, among which 15 proteins were identified, including peptidyl-prolylisomerases A (PPIase A),alpha-enolase,keratin 8,heat shock protein 90, eukaryotic translation initiation factor 1A, and so on.
CONCLUSION:Fifteen proteins in human cervical carcinoma cells paclitaxel-treated and paclitaxel-untreated are found by proteomic techniques. These proteins may be involved in the proliferation inhibition of human cervical carcinoma cells by paclitaxel.
