Abstract

Colorectal cancer (CRC) remains a leading cause of cancer-related deaths, creating an urgent need for innovative diagnostic solutions. Mechanobiology, a cutting-edge field that investigates how physical forces influence cell behavior, is now revealing new insights into cancer progression. This research focuses on two crucial players: RhoA and Rac1, small yet powerful proteins that regulate the structure and movement of cancer cells. RhoA controls cell adhesion and migration, while Rac1 drives cell movement and invasion. As CRC tumors grow and reshape the colon's mechanical environment, these pathways become disrupted, accelerating cancer progression. Examining the level of RhoA and Rac1 in CRC clinical samples under mechanical strain reveals their potential as diagnostic markers. Tracking the activity of these proteins can unlock valuable insights into cancer cell dissemination, offering new avenues for understanding and diagnosing CRC. This approach holds promise for earlier detection and better outcomes by offering key insights for more effective diagnostic strategies.
