Why the study?

Does angptl2 knockdown prevent high-fat diet-induced endothelial dysfunction and metabolic stress in mice?

Population

Wild-type (WT) and angiopoietin-like-2 (angptl2) knockdown (KD) mice

Comparison

Angptl2 knockdown and 3-month high-fat diet vs Wild-type (WT) mice on 3-month high-fat diet (HFD)

Design

Preclinical

Follow-up

3 months

Implication

Angptl2 may be a target in diet-induced endothelial dysfunction; leaves open human translation from this animal model.

Structured PICO

Does angptl2 knockdown prevent high-fat diet-induced endothelial dysfunction and metabolic stress in mice?

P
Population
Wild-type (WT) and angiopoietin-like-2 (angptl2) knockdown (KD) mice
I
Intervention
Angptl2 knockdown (genetic model) and 3-month high-fat diet (HFD)
C
Comparator
Wild-type (WT) mice on 3-month high-fat diet (HFD)
O
Outcome
Endothelial function (acetylcholine-mediated vasodilation) and metabolic stress markers (lipid profiles, fat accumulation, inflammatory gene expression)surrogate

Knockdown of angptl2 protects mice against high-fat diet-induced endothelial dysfunction and metabolic stress.
