  • Title: [Study on the expression of eIF families after elemene treatment].
    Author: Tao L, Zhou L.
    Journal: Lin Chuang Er Bi Yan Hou Ke Za Zhi; 2004 Jun; 18(6):367-9, 375. PubMed ID: 15354786.
    Abstract:
    OBJECTIVE: To investigate the activity of Caspase-3 and the expression of eukaryotic initiation factor families, bFGF and VEGF after elemene on laryngeal carcinoma HEp-2 cells. METHOD: The HEp-2 cells after elemene treatment were analyzed utilizing Westernblot and reverse transcriptase polymerase chain reaction (RT-PCR). The activity of Caspase-3 was assessed by colorimetric assay. RESULT: The activity of Caspase-3 was enhanced after elemene treatment. The protein expression of eIF4E, eIF4G, bFGF and VEGF were significantly inhibited by elemene; and the mRNA expression of bFGF and VEGF were inhibited either. CONCLUSION: Elemene can effectively inhibit the growth of HEp-2 cells and result in the alteration of activity of Caspase-3. There were significant correlations between the decreased expression of protein eIF4E, eIF4G, bFGF and VEGF. The mechanism of eIF4E and eIF4G decrease the expression of bFGF and VEGF is post-transcriptional.
