Effects of procaine on human nasopharyngeal carcinoma cell strain CNE-2Z / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the effects of procaine on human nasopharyngeal carcinoma cell strain CNE-2Z.@*METHOD@#CNE-2Z cells-cultured in vitro-were exposed to different concentration procaine and different time. Its growth characteristic were studied by using MTT assay and flow cytometry. The expression of p16 and RASSF1A mRNA were analyzed by RT-PCR.@*RESULT@#Procaine could inhibit the proliferation of CNE-2Z cells and the effects were in dose- and time-dependent manners. Procaine also arrested CNE-2Z cells in G1 phase of cell cycle. The expression of RASSF1A mRNA was up-regulated in CNE-2Z cells treated with procaine, but no obvious change was found in the expression of p16 mRNA.@*CONCLUSION@#Procaine could inhibit cell growth and up-regulate the expression of RASSF1A mRNA, which may play an important role in CNE-2Z cells' proliferation inhibition induced by procaine.
