侵袭性乳腺肿瘤细胞产生转移基因骨桥蛋白的三种剪接变体,而非侵袭性乳腺细胞仅表达未剪接形式或根本不表达骨桥蛋白。骨桥蛋白在肿瘤进展中的一个作用是支持锚定独立性。在这里,我们表明,全长基因产物,骨桥蛋白-a,诱导的基因表达谱与组织重塑和定向运动/发芽。这是通过STAT 1和STAT 3信号传导至甘油-3-磷酸胆碱而发生的。骨桥蛋白-a可能通过STAT 3及其转录靶点载脂蛋白D和IGFBP 5上调乳腺癌细胞中的葡萄糖水平。剪接变体骨桥蛋白-a和骨桥蛋白-c可以协同作用,每种形式激活不同于另一种的信号转导途径。升高的葡萄糖被骨桥蛋白-c依赖性信号用于产生化学能(Shi等人提交的手稿)。骨桥蛋白的剪接变体特异性代谢作用为该分子的促转移功能增加了一个新的方面。
Invasive breast tumor cells generate three splice variants of the metastasis gene osteopontin, while non-invasive breast cells express only the unspliced form or no osteopontin at all. One role for osteopontin in tumor progression is the support of anchorage-independence. Here we show that the full-length gene product, osteopontin-a, induces a gene expression profile that is associated with tissue remodeling and directed movement/sprouting. This occurs via signals through STAT1 and STAT3 to snglycero-3-phosphocholine. Osteopontin-a upregulates the levels of glucose in breast cancer cells, likely through STAT3 and its transcriptional targets apolipoprotein D and IGFBP5. The splice variants osteopontin-a and osteopontin-c may synergize, with each form activating signal transduction pathways that are distinct from the other. The elevated glucose is used by osteopontin-c dependent signals to generate chemical energy (Shi et al. manuscript submitted). The splice variant-specific metabolic effects of osteopontin add a novel aspect to the pro-metastatic functions of this molecule.
