Pharmacological manipulation of cholesterol endocytosis could be a novel therapeutic target in this setting.Even a short course of mechanical ventilation, such as during major surgery, promotes lung cancer dissemination. A mechanodependent modulation of cholesterol intake regulates cancer cell stiffness and could be a new therapeutic target in this setting. https://bit.ly/3G0IbcI
