接触抑制使非癌细胞在相互接触时停止增殖和生长。当细胞发生恶性转化时,这种特性就会丧失,导致不受控制的增殖和实体瘤形成。在这里,我们报告说,自噬是妥协的接触抑制细胞在2D或3D软细胞外基质文化。在这些细胞中,雅普/TAZ不能共转录调节肌球蛋白-II基因的表达,导致F-肌动蛋白应力纤维的丢失,这损害了自噬体的形成。接触抑制导致的增殖减少部分是自噬依赖性的,因为它们对缺氧和葡萄糖饥饿的敏感性增加。这些发现定义了机械抑制的雅普/TAZ活性如何影响自噬,以促成由各种癌症中丢失的高细胞融合引起的核心表型。在高细胞密度下或当接种在软基质上时,雅普/TAZ从细胞核重新分布到胞质溶胶,变得转录失活。在这里,作者表明,在高细胞密度下,由于肌动球蛋白基因的雅普/TAZ依赖性转录减少,自噬体形成受损
Contact inhibition enables noncancerous cells to cease proliferation and growth when they contact each other. This characteristic is lost when cells undergo malignant transformation, leading to uncontrolled proliferation and solid tumor formation. Here we report that autophagy is compromised in contact-inhibited cells in 2D or 3D-soft extracellular matrix cultures. In such cells, YAP/TAZ fail to co-transcriptionally regulate the expression of myosin-II genes, resulting in the loss of F-actin stress fibers, which impairs autophagosome formation. The decreased proliferation resulting from contact inhibition is partly autophagy-dependent, as is their increased sensitivity to hypoxia and glucose starvation. These findings define how mechanically repressed YAP/TAZ activity impacts autophagy to contribute to core phenotypes resulting from high cell confluence that are lost in various cancers. At high cell density or when plated on soft matrix, YAP/TAZ are redistributed from the nucleus to the cytosol, becoming transcriptionally inactive. Here the authors show that at high cell density, autophagosome formation is impaired due to reduced YAP/TAZ-dependent transcription of actomyosin genes
