Abstract
Objective: Synovial sarcoma (SS) is a malignant mesenchymal tumor that accounts for 5-10% of all soft tissue sarcoma. IL-1β, a pleiotrophic cytokine, has been found in the tumor microenvironment which plays crucial roles in the pathogenesis of tumors. Methods: In this study, we used Hs701.T as a cellular model to study the short-term (4-h) and long-term (48-h) stimulatory effect of IL-1β on cell proliferation and differential gene expression. Results: The results showed that IL-1β can stimulate cell proliferation through activation of NF-κB and AP-1 transcription factors; sequentially triggers the expression of genes related to tumor progression. The microarray data indicated that most of the up-regulated genes were related to tumor progression. Five candidate genes which are involved in the mediation of proliferation (IL-6), apoptosis (Hsp27 and Daxx), and angiogenesis (PlGF and SPARC) were further validated by RT-PCR. Conclusion: These findings may be useful for understanding the pathogenesis of synovial sarcoma.
