@article{14080, abstract = {Extracellular signal-regulated kinase (ERK) has been recognized as a critical regulator in various physiological and pathological processes. Extensive research has elucidated the signaling mechanisms governing ERK activation via biochemical regulations with upstream molecules, particularly receptor tyrosine kinases (RTKs). However, recent advances have highlighted the role of mechanical forces in activating the RTK–ERK signaling pathways, thereby opening new avenues of research into mechanochemical interplay in multicellular tissues. Here, we review the force-induced ERK activation in cells and propose possible mechanosensing mechanisms underlying the mechanoresponsive ERK activation. We conclude that mechanical forces are not merely passive factors shaping cells and tissues but also active regulators of cellular signaling pathways controlling collective cell behaviors.}, author = {Hirashima, Tsuyoshi and Hino, Naoya and Aoki, Kazuhiro and Matsuda, Michiyuki}, issn = {1879-0410}, journal = {Current Opinion in Cell Biology}, number = {10}, publisher = {Elsevier}, title = {{Stretching the limits of extracellular signal-related kinase (ERK) signaling — Cell mechanosensing to ERK activation}}, doi = {10.1016/j.ceb.2023.102217}, volume = {84}, year = {2023}, } @article{6631, abstract = {The spatiotemporal organization of cell divisions constitutes an integral part in the development of multicellular organisms, and mis-regulation of cell divisions can lead to severe developmental defects.

Moreover, cell divisions are associated with an extensive reorganization of the cytoskeleton and adhesion apparatus in the dividing cells that in turn can affect large-scale tissue rheological properties.
