Colorectal cancer liver metastatic (CRCLM) tumours present as two main histopathological growth patterns (HGPs) including desmoplastic HGP (DHGP) and replacement HGP (RHGP). The DHGP tumours obtain their blood supply by sprouting angiogenesis, whereas the RHGP tumours utilize an alternative vascularisation known as vessel co-option. In vessel co-option, the cancer cells hijack the mature sinusoidal vessels to obtain blood supply. Vessel co-option has been reported as an acquired mechanism of resistance to anti-angiogenic treatment in CRCLM. Here, we show the connection between the concentration of serum cholesterol and the development of vessel co-option in CRCLM. Our clinical data suggested that the elevation of serum cholesterol levels correlates with the risk of developing vessel co-opting tumours. Moreover, inhibition of the key modulators of cholesterol metabolism including HMGCR or PCSK9 attenuated the development of CRCLM tumours, as well as vessel co-option in vivo. Altogether, our data uncovered the importance of cholesterol in the development of vessel co-option tumours and demonstrated PCSK9 and HMGCR inhibitors as promising strategies to mitigate the development of vessel co-option tumours in CRCLM.
