Does induction of tissue kallikrein in human carotid atheroma lead to kallikrein-kinins pathway activation?
All KKS components were synthesized in arterial wall except kininogen probably coming from plasma. The absence of PK-G mRNA down-regulation in atheroma suggests that the kallikrein induction does not lead to KKS activation.
The data indicate that irbesartan effectively decreases blood pressure and renal AngII levels, and improves albuminuria. Our findings indicate that vitamin D enhances klotho expression, suppressing oxidative stress and albuminuria without substantial changes in renal AngII levels. These results suggest that the amelioration of endothelium function by vitamin D involves free klotho.
