In addition, it shows a high affinity for the cluster of differentiation-44 (CD44), a transmembrane glycoprotein that, besides participating in physiological processes, including cellular adhesion and migration in inflammation and repair [85], has been found to be overexpressed on the surface of a variety of cancer cells, particularly in solid tumors such as breast, cervical, and prostate cancer and glioblastoma [86]. The gene discussed is CD44; the disease is cancer.
