Modelling hypercholesterolaemia in rats using high cholesterol diet

Area of Science:

• Biochemistry
• Cardiovascular Research
• Animal Models

Background:

• Hypercholesterolaemia is a complex condition with multifactorial causes, including genetic and lifestyle influences.
• It is a significant risk factor for cardiovascular diseases (CVDs), contributing to millions of deaths annually.
• Understanding hypercholesterolaemia's pathobiology is crucial for developing novel therapeutics.

Purpose of the Study:

• To review the current understanding of human hypercholesterolaemia's metabolic profile.
• To comment on the lack of consensus regarding optimal hypercholesterolaemia induction protocols in animal models.
• To review experimental studies inducing hypercholesterolaemia in Wistar rats.

Main Methods:

• Literature review of experimental studies.
• Focus on studies utilizing Wistar rats for hypercholesterolaemia induction.
• Analysis of metabolic profiles and induction protocols.

Main Results:

• Wistar rats fed a hypercholesterolaemic diet serve as a viable animal model for human condition.
• Various induction protocols exist, with no single consensus method.
• All reviewed models successfully increased serum cholesterol levels.

Conclusions:

• Animal models, particularly Wistar rats, are valuable tools for elucidating hypercholesterolaemia pathobiology.
• Further research is needed to standardize induction protocols for consistent results.
• Understanding these models aids in the development of new therapeutic strategies for hypercholesterolaemia and associated CVDs.
