Computational investigation of the functional landscape of the protective role that extra virgin olive oil consumption may have on chronic lymphocytic leukemia

The health benefits of the Mediterranean diet are partially attributed to the polyphenols present in extra virgin olive oil (EVOO), which have been shown to have anti-cancer properties. However, the possible effect that EVOO could have on Chronic Lymphocytic Leukemia (CLL) has not been fully explored.

 This study investigates the anti-CLL activity of EVOO through a computational multi-level data analysis procedure, focusing on the identification of shared biological functions between them. Specifically, publicly available data from genomics, transcriptomics and proteomics related to EVOO consumption and CLL were collected from several resources and analyzed through a computational pipeline, highlighting common molecular mechanisms and biological processes. Computational verification of a number of the highlighted functional terms associating CLL and EVOO has been performed as well.

Our investigation revealed four molecular pathways and three biological processes that overlap between mechanisms associated with CLL and those impacted by the consumption of EVOO. To further investigate the common biological functions, we focused on AKT1-related terms, aiming to investigate the potential importance of AKT1 in the anti- CLL effects associated with EVOO.

Overall, the results provide valuable insights into the potential beneficial effect of EVOO in CLL and highlight EVOO’s bioactive compounds as promising candidates for future investigations.
