Why the study?

The mechanisms of cardiac fibrosis in heart failure remain incompletely understood, prompting investigation into the molecular role of IGF1R in Ang II-induced cardiac fibrosis.

Does IGF1R deficiency alleviate Angiotensin II-induced cardiac fibrosis in mouse models?

Population

C57BL/6J and Igf1r+/- mice, primary mouse cardiac cells, and patients with heart failure

Comparison

IGF1R deficiency or inhibition vs controls under Ang II stimulation

Design

Preclinical in vitro and in vivo laboratory study with human observational blood samples

Follow-up

2 weeks

Key result

IGF1R signaling deficiency alleviated Angiotensin II-induced cardiac fibrosis in mice, partially through inhibiting endothelial-mesenchymal transition via the Akt/ERK/NF-κB pathway.

Overview

Animal findings suggest IGF1R as fibrosis target; leaves open translation to human disease.

Structured PICO

Does IGF1R deficiency alleviate Angiotensin II-induced cardiac fibrosis in mouse models?

P
Population
Primary mouse cardiac microvascular endothelial cells and fibroblasts; C57BL/6J mice and CRISPR/Cas9-mediated IGF1R heterozygous knockout (Igf1r+/-) mice; patients with heart failure and healthy individuals.
I
Intervention
IGF1R deficiency (Igf1r+/-) or inhibition of IGF1R signaling
C
Comparator
Wild type mice or uninhibited cells treated with Angiotensin II
O
Outcome
Cardiac fibrosis and endothelial-mesenchymal transitionsurrogate

IGF1R signaling deficiency alleviates Angiotensin II-induced cardiac fibrosis by inhibiting endothelial-mesenchymal transition via the Akt/ERK/NF-κB pathway, suggesting IGF1R as a potential therapeutic target.

Cite This Study

Zhu et al. (2023) studied Cardiac fibrosis. IGF1R deficiency (Igf1r+/- mice) vs. Wild type mice was evaluated on Cardiac fibrosis and endothelial-mesenchymal transition. IGF1R signaling deficiency alleviated Angiotensin II-induced cardiac fibrosis in mice, partially through inhibiting endothelial-mesenchymal transition via the Akt/ERK/NF-κB pathway.
