The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

open access: yesMedicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),
