Figure 2

Pre-embedding immuno-electron microscopy for SGLT2.

Notes: SGLT2 staining was positive in the brush border membrane (marked with *) of the S1 (A) and S2 segments (B) of the proximal convoluted tubules, but not the S3 segment (C) of the proximal straight tubules, in the diabetic rats (upper panel). The SGLT2 expression in the S1 segment of the proximal convoluted tubules in the control rats (D) was enhanced strongly in the DM rats (E), while ARB therapy (F) reversed this increase to the control level (lower panel). The figures for the SGLT2 expression reflect data obtained under starvation conditions, while the results include some findings obtained under fed conditions (data not shown). The arrows indicate apical vesicles. The bar indicates 1 μm. N=3 in each group.

Abbreviations: ARB, angiotensin receptor blocker; SGLT, sodium-glucose co-transporters; DM, diabetes mellitus.
