长非编码 RNA (lncRNA) 发挥多种细胞作用,包括转录和翻译的调节,从而导致基因表达的改变。一些 lncRNA 调节染色体邻近基因的表达。在这里,我们评估了 lncRNA CASC15 在调节染色体附近基因 SOX4 中的作用及其在 RUNX1/AML 易位白血病中的功能。 CASC15 是一种保守的 lncRNA,在 t (12; 21) 的儿童 B 急性淋巴细胞白血病 (B-ALL) 以及 t (8; 21) 的儿童急性髓细胞白血病 (AML) 中表达上调,这两种情况都与相对较好的预后相关。 CASC15 的强制表达导致发育中的骨髓偏向,总体而言,植入和集落形成减少。在细胞水平上,CASC15 调节细胞存活、增殖及其染色体邻近基因 SOX4 的表达。 CASC15 敲除后的差异调节基因针对阴阳 1 (YY1) 转录因子的预测转录靶标而富集。有趣的是,我们发现 CASC15 增强了 YY1 介导的 SOX4 启动子的调节。我们的研究结果首次表征了 RUNX1 易位白血病中的 CASC15,并指出了其作用的机制基础。本文的在线版本 (doi:10.1186/s12943-017-0692-x) 包含补充材料,可供授权用户使用。
Long non-coding RNAs (lncRNAs) play a variety of cellular roles, including regulation of transcription and translation, leading to alterations in gene expression. Some lncRNAs modulate the expression of chromosomally adjacent genes. Here, we assess the roles of the lncRNA CASC15 in regulation of a chromosomally nearby gene, SOX4, and its function in RUNX1/AML translocated leukemia. CASC15 is a conserved lncRNA that was upregulated in pediatric B-acute lymphoblastic leukemia (B-ALL) with t (12; 21) as well as pediatric acute myeloid leukemia (AML) with t (8; 21), both of which are associated with relatively better prognosis. Enforced expression of CASC15 led to a myeloid bias in development, and overall, decreased engraftment and colony formation. At the cellular level, CASC15 regulated cellular survival, proliferation, and the expression of its chromosomally adjacent gene, SOX4. Differentially regulated genes following CASC15 knockdown were enriched for predicted transcriptional targets of the Yin and Yang-1 (YY1) transcription factor. Interestingly, we found that CASC15 enhances YY1-mediated regulation of the SOX4 promoter. Our findings represent the first characterization of this CASC15 in RUNX1-translocated leukemia, and point towards a mechanistic basis for its action.
