LUCAT1通过与SRSF1相互作用上调MCL-1促进非小细胞肺癌的迁移和侵袭。
非小细胞肺癌(NSCLC)的发病尚不明确。LUCAT1可能通过靶向SRSF1调节MCL-1参与的NSCLC发病机制。MCL-1还可以调节Wnt/β-catenin通路,影响NSCLC的肿瘤发生。因此,本文旨在揭示基于Wnt/β-catenin通路的LUCAT1/SRSF1/MCL-1轴在NSCLC中的有趣而新颖的作用。A549和NCI-H1650这两种NSCLC细胞系被用于体外模拟NSCLC。MCL-1 siRNA(si-MCL-1)和LUCAT1 siRNA(si-LUCAT1)分别用于下调NSCLC细胞中的MCL-1和LUCAT1。构建了基于pcDNA 3.1的SRSF1过表达载体以上调SRSF1的表达。40μM SKL2001激活Wnt/β-catenin通路。Transwell测定用于迁移和侵入性测试。LUCAT1对肿瘤转移的作用在裸鼠中得到验证。MCL-1下调导致NSCLC中EMT、侵袭和迁移的减少,而Wnt/β-catenin通路激动剂部分逆转了MCL-1的下调作用。机制研究表明,LUCAT1和MCL-1 mRNA在SRSF1中富集;LUCAT1沉默降低MCL-1,而SRSF1增强提高MCL-1;重要的是,SRSF1过表达显著逆转了由于LUCAT1沉默引起的MCL-1改变。在NSCLC细胞中,SRSF1过表达抵消了si-LUCAT1诱导的变化,而si-MCL-1逆转了SRSF1诱导的细胞变化。此外,LUCAT1抑制减少了癌症细胞的肺转移。LUCAT1可以与SRSF1相互作用,调节MCL-1的表达,MCL-1靶向Wnt/β-catenin途径介导的NSCLC细胞迁移、侵袭和EMT。

期刊介绍: Molecular and Cellular Biochemistry: An International Journal for Chemical Biology in Health and Disease publishes original research papers and short communications in all areas of the biochemical sciences, emphasizing novel findings relevant to the biochemical basis of cellular function and disease processes, as well as the mechanics of action of hormones and chemical agents. Coverage includes membrane transport, receptor mechanism, immune response, secretory processes, and cytoskeletal function, as well as biochemical structure-function relationships in the cell. In addition to the reports of original research, the journal publishes state of the art reviews. Specific subjects covered by Molecular and Cellular Biochemistry include cellular metabolism, cellular pathophysiology, enzymology, ion transport, lipid biochemistry, membrane biochemistry, molecular biology, nuclear structure and function, and protein chemistry.
