TRIM24, originally known as intermediary factor 1-alpha, is involved in the development of several cancers. This study aimed to evaluate the expression level and prognostic value of TRIM24 in cervical cancer. In the present study, we showed that the expression of TRIM24 was markedly upregulated in cervical cancer cell lines and cancerous specimens at both transcriptional and translational levels. TRIM24 expression was analyzed in 147 archived cervical cancer specimens using immunohistochemistry, and the correlation between TRIM24 expression and clinicopathological parameters was evaluated. Statistical analysis suggested that TRIM24 expression was significantly correlated with clinical stage and (P=0.007) and lymphatic metastasis (P=0.001). Patients with higher TRIM24 expression had shorter overall (P=0.005) and recurrence-free (P=0.011) survival time. Moreover, we found that silencing TRIM24 by short hairpin RNAi caused an inhibition of cell migration and invasion. Further study indicated that TRIM24 induced cervical cancer cell migration and invasion was through the NF-κB and AKT signaling pathways. In conclusion, TRIM24 is overexpressed in cervical cancer and regulates malignant cell metastasis, which makes TRIM24 a candidate therapeutic target for cervical cancer.
TRIM24最初被称为中间因子1-α,与多种癌症的发生发展有关。本研究旨在评估TRIM24在宫颈癌中的表达水平及预后价值。在本研究中,我们发现TRIM24在宫颈癌细胞系和癌组织标本中的转录和翻译水平均显著上调。采用免疫组织化学方法分析了147例存档宫颈癌标本中TRIM24的表达情况,并评估了TRIM24表达与临床病理参数之间的相关性。统计学分析表明,TRIM24表达与临床分期(P=0.007)和淋巴结转移(P=0.001)显著相关。TRIM24表达较高的患者总生存期(P=0.005)和无复发生存期(P=0.011)较短。此外,我们发现通过短发夹RNA干扰沉默TRIM24可抑制细胞迁移和侵袭。进一步研究表明,TRIM24诱导宫颈癌细胞迁移和侵袭是通过NF-κB和AKT信号通路。总之,TRIM24在宫颈癌中过度表达并调节恶性细胞转移,这使得TRIM24成为宫颈癌的一个候选治疗靶点。
