摘要: 目的 探讨TGF-β1/MAPKs/MMPs信号通路相关的microRNA (miRNA)在唾液腺腺样囊性癌(salivary adenoid cystic carcinoma, SACC)侵袭、转移中的作用。方法:采用 miRNA 芯片检测TGF-β1 刺激腺样囊性癌细胞(SACC-83、SACC-LM)前、后的miRNA表达谱;对 miRNA 表达谱进行差异分析;然后挑选几个显著差异表达的miRNA,采用实时荧光定量PCR(qRT-PCR)进一步加以验证,同时运用miRNA 靶基因预测软件预测其可能调控的靶基因。结果:芯片结果显示,与低转移株SACC-83相比,高转移株SACC-LM中的miRNA上调表达40个,下调表达 101个;经TGF-β1处理后,进一步显著上调的miRNA 1个,下调12个;qRT-PCR 验证结果与 miRNAs 芯片相符。对显著差异表达的miRNAs进行靶基因预测,共筛选出与 TGF-β1/MAPKs/MMPs信号通路相关的5个miRNAs(miR-125a-5p、miR-181d、mir-145-3p、mir-126-3p和mir-320d),其对应的靶基因有P38(MAPK14)、MMP2、ERK1/2和SMADs。结论:不同转移能力的SACC存在差异表达的 miRNAs;TGF-β1能够影响SACC细胞miRNAs 的表达;miR-125a-5p、miR-34a、mir-145-3p、mir-126-3p和mir-195可能在SACC转移相关信号调节通路TGF-β1/MAPKs/MMPs中起着重要的调控作用。

Abstract: PURPOSE: To illustrate the relationship between TGF-β1/MAPKs/MMPs signaling pathway and microRNA (miRNA) expression, and to explore the potential role of miRNA in the metastasis of salivary adenoid cystic carcinoma (SACC). METHODS: MiRNA array was performed to analyse the changes of miRNA expression inSACC cells before or after TGF-β1 stimulation, and then several significant different microRNAs were selected to be verified by qRT-PCR assay. Meanwhile, their target genes were predicted by miRNA target gene prediction programs. RESULTS: MicroRNA microassay showed that SACC_LM_neg/SACC_83_neg: up 40, down 101.One of them was up-regulated and twelve miRNAs of them were down- regulated after treated by TGF- β1 which were accordant with the results of qRT-PCR assay. MiR-125a-5p, miR-181d , mir-145-3p, mir-126-3p and mir-320d were chosen and several genes were predicted as targets of these differently regulated miRNAs related to TGF-β1/MAPKs/MMPs signaling pathway. CONCLUSION: There are differentially expressed microRNAs between SACC-LM and SACC-83. TGF-β1 can affect miRNAs profiling of SACC. MiR-125a-5p, miR-181d, mir-145-3p, mir-126-3p and mir-320d may be regulated by TGF-β1/MAPKs/MMPs signaling pathway.
