Abstract:
Aim To observe the effect and primary mechanism of arctigenin ( ARG) in C6 rat glioma. At the same time, to investigate the effect of ARG com-bined with temozolomide. Methods C6 glioma rat model was established, and 90 rats were divided into six groups, which were subcutaneously administered with model, low and high ARG (0. 05 and 0. 1 mg· kg-1 , sc) , temozolomide (20 mg·kg-1 , p. o. ) , low ARG combined with temozolomide(TMZ / ARG 0. 05) and high ARG combined with temozolomide ( TMZ /ARG 0. 1 ) . The tumor specimens of brain were col-lected after tumor graft. Proliferating cell nuclear anti-gen ( PCNA ) , glial fibrillary acidic protein ( GFAP ) and CD40 in tumor specimens were determined by im-munohistochemistry. Results ① Compared with the model group, the tumor sizes of rats in the arctigenin treatment groups were decreased ( P<0. 05 ) . ②ARG
significantly decreased PCNA and CD40 expression ( P<0. 05 ) and increased GFAP expression ( P<0. 05 ) .③ Compared with model group, arctigenin combined with temozolomide decreased the tumor sizes ( P <0. 01 ) , and the tumor inhibition rate was higher than that of the arctigenin and temozolomide. At the same time, arctigenin combined with temozolomide de-creased PCNA and CD40 expression ( P <0. 01 ) and increased GFAP expression ( P <0. 05 ) , which was better than arctigenin and temozolomide. Conclusion Arctigenin inhibits rat glioma growth, and synergizes with temozolomide, which may be associated with in-hibiting PCNA and CD40 expression and strengthening GFAP expression.
