Although the number of studies on the role of galectin-4 in cancer remains relatively low (approximately 60 studies in the last ten years, compared to more than a thousand for galectin-3, for example), we are starting to get a better view of its possible implication in cancer, not only outside the cells but also inside, allowing us to pinpoint its role in cancer progression (24–27). The gene discussed is LGALS3; the disease is cancer.
