Melanoma is the most fatal form of skin cancer, with increasing prevalence worldwide. The most common melanoma genetic driver is mutation of the proto-oncogene serine/threonine kinase BRAF; thus, the inhibition of its MAP kinase pathway by specific inhibitors is a commonly applied therapy. However, many patients are resistant, or develop resistance to this type of monotherapy, and therefore combined therapies which target other signaling pathways through various molecular mechanisms are required. A possible strategy may involve targeting cellular energy metabolism, which has been recognized as crucial for cancer development and progression and which connects through glycolysis to cell surface glycan biosynthetic pathways. Protein glycosylation is a hallmark of more than 50% of the human proteome and it has been recognized that altered glycosylation occurs during the metastatic progression of melanoma cells which, in turn facilitates their migration. This review provides a description of recent advances in the search for factors able to remodel cell metabolism between glycolysis and oxidative phosphorylation, and of changes in specific markers and in the biophysical properties of cells during melanoma development from a nevus to metastasis. This development is accompanied by changes in the expression of surface glycans, with corresponding changes in ligand-receptor affinity, giving rise to structural features and viscoelastic parameters particularly well suited to study by label-free biophysical methods.
黑色素瘤是最致命的皮肤癌形式,在全球范围内发病率不断上升。最常见的黑色素瘤基因驱动因素是原癌基因丝氨酸/苏氨酸激酶BRAF的突变;因此,用特异性抑制剂抑制其丝裂原活化蛋白激酶途径是一种常用的治疗方法。然而,许多患者对此类单一疗法耐药,或会产生耐药性,因此需要通过各种分子机制靶向其他信号通路的联合疗法。一种可能的策略可能涉及靶向细胞能量代谢,细胞能量代谢已被认为对癌症的发生和发展至关重要,并且通过糖酵解与细胞表面聚糖生物合成途径相连。蛋白质糖基化是超过50%的人类蛋白质组的一个标志,并且人们已经认识到,在黑色素瘤细胞的转移过程中会发生糖基化改变,这反过来又促进了它们的迁移。本综述描述了在寻找能够重塑糖酵解和氧化磷酸化之间细胞代谢的因素方面的最新进展,以及在黑色素瘤从痣发展到转移的过程中细胞的特定标志物和生物物理特性的变化。这种发展伴随着表面聚糖表达的变化,配体-受体亲和力也相应改变,从而产生特别适合通过无标记生物物理方法研究的结构特征和粘弹性参数。
