Shedding light on the roles of liver X receptors in cancer by using chemical probes
Lorenzo Pontini, Maura Marinozzi
Abstract
Nuclear receptors, liver X receptor-α (LXRα; NR1H3) and liver X receptor-β (LXRβ; NR1H2), are considered master regulators of lipid homeostasis. During the last couple of decades, their pivotal roles in several physiological and pathological processes ranging from energy supply, immunity, cardiovascular, neurodegenerative disorders and cancer have been highlighted. In this review, the main results achieved during more recent years about our understanding of the LXR involvement in cancer has been mainly obtained using small-molecule chemical probes. Remarkably, all these probes, albeit having different structure and biological properties, have a well demonstrated anti-tumoral activity arising from LXR modulation, indicating a high potential of LXR targeting for the treatment of cancer.
