摘要
目的：评估叉头框蛋白M1(forkhead box protein M1，FOXM1)在结直肠癌(colorectal cancer，CRC)的发生发展中的作用。方法：研究103例原发CRC和配对的正常组织标本，探讨FOXM1表达变化的潜在机制及其对体外CRC细胞模型的增殖和转移的影响。结果：103例CRC组织染色后FOXM1阳性率为85.44%(88/103)，癌旁正常组织中阳性率为20.39%(21/103)。两组间的FOXM1的表达差异具有统计学意义(P<0.001)；FOXM1沉默能抑制结肠癌细胞的增殖，且侵袭和迁移也明显受抑。结论：CRC的发病机制可能是由FOXM1介导，FOXM1可能代表CRC分子靶向治疗的选择性靶点。

Abstract
Objective: To evaluate the role of the forkhead box M1 (FOXM1) in colorectal cancer (CRC) tumorigenesis. Methods: We investigated FOXM1 expression in 103 cases of primary CRC and matched normal tissue specimens and explored the underlying mechanisms of altered FOXM1 expression and the impact of this altered expression on CRC proliferation and metastasis using in vitro models of CRC. Results: The results showed that high expression of FOXM1 staining was 85.44% (88/103) in 103 cases of CRC and 20.39% (21/103) in 103 cases of adjacent non-cancerous tissue samples; the difference of FOXM1 expression between two groups was statistically significant (P<0.001). Silencing of FOXM1 inhibited the proliferation of CRC cells, and the invasion and migration of CRC cells were distinctly suppressed. Conclusion: The pathogenesis of CRC maybe mediated by FOXM1, and FOXM1 could represent selective targets for the molecularly targeted treatments of CRC.
