Abstract:
Objective: To study the mechanism of chitosan i n inhibiting the proliferation of rabbit aortic smooth muscle cells(SMCs). Methods: By means of c-myc probe labelled with random primers and Northern blot hybridization, we examined the effect of chitosan on vascu lar SMC c- myc mRNA expression, which was stimulated by newborn bull serum (NB S,20%). Results: The oncogene c-myc mRNA expression incerased in cultured vascular SMC 24 h after NBS exposure. These effects were inhibite d by chitosan (20 μg/ml). Conclusion: Chitosan might inhibit the expression of vascular SMC c-myc mRNA stimulated by NBS, through which the proliferation of vascular SMC are inhibited.
