Key result

Transfection of decoy ODN against AGE 2, but not AGE 3 or mismatched ODN, resulted in a transient decrease in blood pressure and angiotensinogen levels in spontaneously hypertensive rats.

Why the study?

Does transfection of decoy ODN against AGE 2 or AGE 3 reduce blood pressure in spontaneously hypertensive rats?

Population

Spontaneously hypertensive rats (SHR)

Comparison

Transfection of synthetic double-stranded… vs Mismatched decoy ODN

Preclinical

Implication

AGE 2 decoy reduces BP in SHR models; leaves open whether angiotensinogen cis-element targeting offers viable human therapy.

Structured PICO

Does transfection of decoy ODN against AGE 2 or AGE 3 reduce blood pressure in spontaneously hypertensive rats?

P
Population
Spontaneously hypertensive rats (SHR) used to study the in vivo regulation of the angiotensinogen gene.
I
Intervention
Transfection of synthetic double-stranded oligodeoxynucleotides (ODN) as 'decoy' cis-elements against AGE 2 or AGE 3
C
Comparator
Mismatched decoy ODN
O
Outcome
Blood pressure, hepatic angiotensinogen mRNA, plasma angiotensinogen, and angiotensin II levelssurrogate

Inhibition of the transcriptional cis-element AGE 2 using decoy oligodeoxynucleotides reduces blood pressure and angiotensinogen production in spontaneously hypertensive rats.

Cite This Study

Morishita et al. (1996) studied Hypertension. Decoy oligodeoxynucleotides (ODN) against AGE 2 vs. Mismatched decoy ODN and AGE 3 decoy ODN was evaluated on Blood pressure and angiotensinogen production. Transfection of decoy ODN against AGE 2, but not AGE 3 or mismatched ODN, resulted in a transient decrease in blood pressure and angiotensinogen levels in spontaneously hypertensive rats.
