Figure 15. Glucose transporter genes expressed in retinal pigment epithelium

Expression of the mRNAs for 4 of the facilitated glucose transporters (SLC2A_) increased as tight junctions were forming to close the paracellular pathway to glucose. A Na⁺-coupled glucose transporter (SLC5A1) also increased during this period. Mean values of 3-4 biological replicates are indicated according to the scale, in arbitrary units, depicted at the bottom. Complete gene titles and mean values with the associated p-statistic are listed in the corresponding Appendix 2.
