Figure 7. Glucose transporter genes expressed in the retinal pigment epithelium. Some mRNAs (mRNAs) for glucose transporters were stably expressed during development, such as GLUT3 (SLC2A3), GLUT 4 (SLC2A4), GLUT 8 (SLC2A8), and GLUT 9 (SLC2A9), while the expression of GLUT1 (SLC2A1) and GLUT 10 (SLC2A10) decreased during development.
