Conclusions: Senescence-associated secretory phenotype (SASP) is responsible for chemotherapy adverse effects: drug resistance and the induction of cancer cell proliferation, migration, and invasion. Hence, developing senolytic/semomorphic drugs, targeting senescence cells, are important to improve cancer treatment outcome. In this work, Y. D. Simay with colleagues evaluated if Rho/Rho kinase pathway could be a target for potential drugs in doxorubicin-induced senescent cancer cell lines. Authors have shown that ROCK inhibitors (i.e. ROCK2) have the potential to be developed into semomorphic drugs as they change SASP composition and reduce senescence cell secretory activity. HoloMonitor M4 was used to study cell morphology (cell area, optical volume, and optical thickness).
