Key result

The cloning of the human renin receptor revealed that renin binding increases the catalytic efficiency of angiotensinogen conversion to angiotensin I fourfold and activates MAP kinases ERK1 and ERK2.

Implication

Caution against clinical use from animal data alone; leaves open receptor blockade as a novel RAS target for human trials.

Structured PICO

P
Population
Human kidney cDNA-phage library, immortalized human fetal mesangial cell line (HMC), and human normal kidney, heart, and mature placenta tissues
I
Intervention
Expression cloning of the human renin receptor (N14F) and binding of recombinant human renin and prorenin
C
Comparator
Control cells transfected with empty vector; renin in soluble phase versus membrane-bound renin
O
Outcome
Receptor identification, binding kinetics, catalytic efficiency of angiotensinogen conversion to angiotensin I, and intracellular signaling activation (MAP kinases ERK1/ERK2)

The identification of the first renin/prorenin receptor demonstrates that renin has direct cellular effects independent of angiotensin II and that membrane binding significantly increases its catalytic efficiency.

Cite This Study

Nguyen et al. (2002) studied this question. Renin receptor cloning and characterization was evaluated on Renin receptor identification and functional characterization. The cloning of the human renin receptor revealed that renin binding increases the catalytic efficiency of angiotensinogen conversion to angiotensin I fourfold and activates MAP kinases ERK1 and ERK2.
