Enhanced expression of GLUT-1 has actually been recognized in various cancer tissues examined, since one of the pivotal functions of ubiquitous GLUT-1 is known to particularly increase the glucose supply to dividing and growing cells in part, among a family of GLUT transporters [8,9], possibly unlike these benign myxoma cells with relatively low MIB-1 index. This evidence concerns the gene SLC2A1 and myxoma.
