A multi-omic study describes oxysterol signaling in breast cancer

The study of the roles of oxysterols in cancer is a long-standing interest of the Laboratory of Pharmacogenomics. Oxysterols are oxidized cholesterol derivatives that affect many crucial signaling pathways and are increasingly being studied in cancer cells due to their potential as modulators of hormone signaling, biomarkers, or drugs.

The most recent contribution advancing knowledge in this area is a study entitled "Integrative analysis of mRNA and miRNA expression profiles and somatic variants in oxysterol signaling in early-stage luminal breast cancer", recently published in Molecular Oncology (Wiley, IF=6.6, Q1). The study combines data on expression and somatic mutation of 113 genes that have been shown or predicted to interact with oxysterols with expression data of the entire miRNA transcriptome, and maps their interrelationships as well as their impact on disease prognosis and other clinical factors.
