  • Title: Proteomic analysis of ursolic acid-induced apoptosis in cervical carcinoma cells.
    Author: Yim EK, Lee KH, Namkoong SE, Um SJ, Park JS.
    Journal: Cancer Lett; 2006 Apr 28; 235(2):209-20. PubMed ID: 15925442.
    Abstract:
    Proteomic analyses can efficiently detect the variation of protein in high throughput screening. Using 2DE/MALDI-TOF-MS and SELDI-TOF-MS, we tried to search several cellular proteins that are responsive to ursolic acid (UA) in HeLa cervical carcinoma cells. Compared to control, UA-treated HeLa cells unfolded 25 proteins in significant changes by 2DE/MALDI-TOF-MS, most of which were involved in apoptosis. SELDI-TOF-MS with two types of protein chips profiled and analyzed proteomic features after administration of UA. Interestingly, eight polypeptide peaks can be detected. Further identification and characterization of these proteins may build the molecular basis of UA-induced apoptosis and provide insight into the anti-proliferative mechanism in cervical carcinoma cells.
