Summary
Biological sex significantly impacts lipid and lipoprotein levels, influencing cardiovascular disease risk. Understanding these sex-based differences is crucial for reducing residual cardiovascular disease risks and advancing personalized medicine.
Area of Science:
- Cardiovascular Disease Research
- Lipid Metabolism
- Genetics and Personalized Medicine
Background:
- Cardiovascular disease (CVD) prevention and treatment heavily rely on managing atherogenic lipid and lipoprotein levels.
- Despite advancements, residual CVD risks persist, necessitating exploration of novel targets and personalized approaches.
- Biological sex is a critical, yet often underappreciated, factor influencing lipid profiles and CVD development.
Purpose of the Study:
- To review recent preclinical and clinical studies on the impact of biological sex on plasma lipid and lipoprotein levels.
- To highlight advances in understanding the mechanisms of hepatic lipoprotein production and clearance influenced by sex.
- To emphasize the importance of incorporating sex as a biological variable in CVD research.
Main Methods:
- Systematic review of recent preclinical and clinical studies.
- Analysis of research focusing on sex differences in lipid and lipoprotein metabolism.
- Examination of genetic and personalized medicine approaches in CVD risk assessment.
Main Results:
- Plasma lipid and lipoprotein profiles exhibit significant variations based on biological sex.
- Hepatic lipoprotein production and clearance pathways are differentially regulated by sex, impacting disease presentation.
- Sex-specific differences contribute to residual cardiovascular disease risk.
Conclusions:
- Incorporating biological sex as a variable is essential for a comprehensive understanding of lipid metabolism and CVD.
- Personalized medicine strategies must account for sex-based variations in lipid profiles to effectively mitigate residual CVD risk.
- Further research into sex-specific mechanisms can lead to more targeted and effective CVD therapies.

201
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

01:29Cholesterol: Significance and Regulation
600
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

01:09Hepatic Drug Clearance: Effect of Protein Binding
249
Hepatic clearance is influenced by protein binding based on the drug's extraction ratio. Drugs with high extraction ratios are considered flow-limited and remain unaffected by protein binding during hepatic clearance. On the other hand, drugs with low extraction ratios may be impacted by plasma protein binding, although the extent of this influence depends on the fraction of the drug bound.
For low-extraction-ratio drugs that are less than 80% protein-bound, minor changes in protein binding...

01:09Hepatic Drug Clearance: Restrictive and Nonrestrictive Clearance
153
Hepatic clearance refers to the volume of blood cleared of a drug by the liver per unit of time. It plays a crucial role in drug metabolism and elimination. While hepatic clearance is commonly estimated by subtracting renal clearance from total body clearance, other pathways, such as pulmonary or biliary clearance, may also contribute. However, these pathways are generally less significant than hepatic and renal clearance.
Most drugs undergo restrictive clearance, which is proportional to the...
