GLUT5 increases fructose utilization in ovarian cancer

OncoTargets and Therapy

Abstract

Background: Fructose is one of the most common dietary carbohydrates in the whole world, and recent studies have found that fructose consumption is closely related to the oncogenesis and development of tumors, however, very few studies have focused on the fructose in ovarian cancer. GLUT5 (Glucose transporter type 5), as a specific fructose transporter in mammalian cells, has also been found highly expressed in many cancers. Methods: In this study, we investigated the abilities of proliferation, colony formation, and migration of ovarian cancer cells in fructose medium, and then silenced GLUT5 in ovarian cancer cells to explore the role GLUT5 in fructose metabolism in ovarian cancer. Results: The results showed that the ovarian cancer cells had similar abilities of proliferation and migration in fructose medium and glucose medium, but silencing GLUT5 could significantly inhibit these abilities in fructose medium. Meanwhile, we found that GLUT5 was higher expressed in ovarian cancer tissues, and its expression correlated significantly with tumor malignancy and poor survival of ovarian cancer patients. Furthermore, the results of animal experiments also demonstrated that intake too much fructose could prominently increase tumor v...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
