Figure 5.
AGT protein localization in proximal tubule segment (S) 1 in OLETF and LETO rats. The merged images of AGT protein (A, D, G, and J) and the S1-specific marker SGLT2 (B, E, H, and K) are shown in C (LETO rats), F (OLETF rats), I (OLETF + olmesartan), and L (OLETF + HRH). The calculated AGT protein expression in S1 is shown in M. Each value was expressed as a fold-increase against the average of protein level of LETO rats, which was taken as 1. * P < 0.05 vs. LETO + vehicle. Dotted line indicates edge of kidney. Magnification, x100 (scale bar, 200 μm). High magnification images of C, F, I, and L are also attached. AGT: angiotensinogen; LETO: Long-Evans Tokushima Otsuka; OLETF: Otsuka Long-Evans Tokushima Fatty; SGLT2: sodium glucose cotransporter 2; HRH: hydralazine, reserpine, and hydrochlorothiazide; CO: cortex.
