Of the six isoforms for which we found protein in non-cancerous lung tissue (GLUT-1, -2, -4, -8, -10, and -12), all of the isoforms (with the exception of GLUT10) were determined to have some sort of alteration during diabetes, either in the total cell lysate or at the cell surface of the homogenized lung tissue. The gene discussed is SLC2A1; the disease is diabetes mellitus.
