While significant insights have been gained by a study of cancer genetics, the roles of the cytoplasm in regulating chemical processes during the transformation to malignancy are often less appreciated. The cytoplasm functions as a two-phase system consisting of an elastic solid phase (the cytomatrix) and a viscous liquid phase (the cytosol). This finding has led to the development of a tumor progression model based on a two-phase system that connects genetic alterations with the physicochemical processes necessary for sustaining and facilitating malignant growth. Here, we show that the energy required for tumor growth is, in part, required for the cytomatrix activity, which accelerates chemical reactions. The ability to regulate cytomatrix motor proteins provides a mechanism to control whether a genetic mutation is able to induce the energy needed for cancer to develop and offers innovative strategies for cancer treatment.
虽然对癌症遗传学的研究已经取得了重大进展,但细胞质在向恶性转化过程中调节化学过程的作用却常常被忽视。细胞质作为一个两相系统发挥作用,由弹性固相(细胞基质)和粘性液相(细胞溶胶)组成。这一发现促使基于两相系统的肿瘤进展模型的发展,该模型将基因改变与维持和促进恶性生长所需的物理化学过程联系起来。在这里,我们表明肿瘤生长所需的能量部分用于细胞基质活性,而细胞基质活性会加速化学反应。调节细胞基质运动蛋白的能力提供了一种机制,以控制基因突变是否能够诱导癌症发展所需的能量,并为癌症治疗提供了创新策略。
