Liposarcoma is the most prevalent sarcoma in adults representing 20% of all sarcomas with well-differentiated/dedifferentiated among the most common subtypes represented. Despite multimodality treatment approaches, there has not been any appreciable change in survival benefit in the past 10 years. The future of targeted therapy for WD/DDLPS is promising with the intention to spare multi-visceral removal due to radical surgical resection. Therefore, there is a need to expand upon the molecular landscape of WDLPS and DDLPS which can help identify potential therapeutic targets for the treatment of this disease. Targeted transcriptome analysis using the NanoString tumor signaling 360 panel revealed a dysregulation in glucose metabolism and HIF1 signaling pathways in both WDLPS and DDLPS when compared to normal fat controls. WDLPS, however, demonstrated upregulation of and when compared to DDLPS by targeted transcriptome analysis and orthogonal validation by RT-qPCR suggesting activation of EMT pathway in WDLPS when compared to DDLPS. Our findings implicate a putative role for dysregulation in glucose metabolism, TGF-β and HIF1 signaling in the pathogenesis of both WD/DDLPS suggesting a possible proinflammatory tumor environment within WDLPS and subsequent activation of the TGF-β signaling pathway.
脂肪肉瘤是成人中最常见的肉瘤,占所有肉瘤的20%,其中高分化/去分化型是最常见的亚型。尽管采用了多模式治疗方法,但在过去10年中,生存获益并未有任何明显变化。WD/DDLPS靶向治疗的前景广阔,旨在避免因根治性手术切除而进行多脏器切除。因此,有必要进一步拓展WDLPS和DDLPS的分子图谱,这有助于识别治疗该疾病的潜在治疗靶点。与正常脂肪对照相比,使用NanoString肿瘤信号360检测板进行的靶向转录组分析显示,WDLPS和DDLPS中的葡萄糖代谢和HIF1信号通路均失调。然而,通过靶向转录组分析和RT-qPCR正交验证,与DDLPS相比,WDLPS显示 和 的上调,提示与DDLPS相比,WDLPS中EMT通路被激活。我们的研究结果表明,葡萄糖代谢、TGF-β和HIF1信号失调在WD/DDLPS发病机制中具有假定作用,提示WDLPS中可能存在促炎肿瘤环境以及随后TGF-β信号通路的激活。
