While low levels of ROS can stimulate cell proliferation, excessive ROS lead to cell cycle arrest. Notably, cell cycle arrest can further generate more ROS, creating a bidirectional relationship that underscores the necessity for cells to finely tune ROS levels to maintain homeostasis and ensure proper cell cycle progression. Unlike classical cell cycle checkpoint systems, ROS directly oxidise cysteine residues in critical cell cycle regulators, with examples ranging from cyclins and cyclin-dependent kinases to APC/C, CDK inhibitors, and other CDK regulators, altering their functions.

The fate of these lesions is shaped not only by cell-intrinsic alterations but also by the precancerous microenvironment (PME), an ecosystem of epithelial, stromal and immune cells embedded within the extracellular matrix. Focusing on epithelial precancers, this review first defines the metastable state and signalling networks that distinguish precancer from homeostasis and cancer. It then examines the models and technologies used to investigate PME signalling across spatial–temporal dimensions, followed by an integrated overview of how PME components collectively shape lesion trajectories. Finally, it outlines the outstanding questions and research priorities needed to advance mechanistic insight and realise the translational potential of PME-targeted interventions.</div></div>","PeriodicalId":50608,"journal":{"name":"Current Opinion in Cell Biology","volume":"98 ","pages":"Article 102611"},"PeriodicalIF":4.3,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145925548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The discovery of pointed-end polymerization by the bacterial effector VopF has challenged the barbed-end centric assembly paradigm and reinvigorated efforts to identify endogenous pointed-end elongators.

However, they also influence actin cytoskeleton organisation.

Recent work has identified analogous Ras-dependent actin structures in cancer cells, including actin waves, protrusions and membrane blebs, which promote cell survival and motility. In addition, Ras activation induces changes to signalling networks and gene expression that result in cell-wide changes to actin network architecture, cortex mechanics and cell shape.
