Anoikis in cancer: The role of lipid signaling.

Malignantly transformed cells must alter their metabolic status to stay viable in a harsh microenvironment and maintain their ability to invade and spread. Anoikis, a specific detachment-related form of apoptotic cell death, is a potential barrier to cancer cell metastasis. Several molecular/pathway alterations have been implicated in preventing anoikis in metastatic cancers. Specific alterations in the lipid metabolism machinery (such as an increase in fatty acid uptake and synthesis) and modifications in the carbohydrate and amino acid metabolism are partially identified mechanisms associated with the anoikis resistance in various types of cancers, among other survival benefits. Following a summary of the molecular basis of the anoikis pathway, its resistance mechanisms, and the fundamentals of lipid metabolism in cancer, this article aims to elucidate the impact of lipid metabolism deviations recruited by cancer cells to escape anoikis.
