Summary
Remnant cholesterol, a risk factor for atherosclerotic cardiovascular disease (ASCVD), is influenced by genetic factors. Understanding these genetic determinants, particularly those affecting lipoprotein lipase (LPL), can reveal new therapeutic targets.
Area of Science:
- Cardiovascular Genetics
- Lipid Metabolism
- Pharmacogenomics
Background:
- Remnant cholesterol is an emerging target for reducing residual atherosclerotic cardiovascular disease (ASCVD) risk in statin-treated patients.
- Novel therapies like antisense oligonucleotides and monoclonal antibodies enable targeted intervention in pathological pathways.
- Identifying genetic links to remnant cholesterol can guide the evaluation of drug targets.
Purpose of the Study:
- To explore genetic determinants of remnant cholesterol.
- To investigate the relationship between these genetic factors and ASCVD risk.
- To identify and evaluate potential drug targets for managing remnant cholesterol.
Main Methods:
- Human genetic epidemiology studies.
- Analysis of genetic variants influencing lipoprotein metabolism.
- Investigation of genes affecting lipoprotein lipase (LPL) activity.
Main Results:
- Several genetic variants impacting remnant cholesterol levels have been identified.
- Genes such as APOC3, ANGPTL3, and ANGPTL4, which regulate LPL activity, are key determinants.
- Lipoprotein lipase (LPL) plays a central role in remnant lipoprotein metabolism.
Conclusions:
- Remnant cholesterol is considered a likely causal factor in ASCVD development.
- Genetic studies have pinpointed several genes, many related to LPL function, that influence remnant cholesterol.
- Some identified genes are already therapeutic targets, while others are under investigation for their lipid-lowering effects.

458
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.

03:17Inheritance of Chromatin Structures
6.1K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

02:32Exon Recombination
3.5K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.

01:28Overview of Fatty Acid Metabolism

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

01:24Lipid Absorption
305
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

02:32X and Y Chromosomes
19.6K
Among mammals, the gender of an organism is determined by the sex chromosomes. Humans have two sex chromosomes, X and Y. Every human diploid cell has 22 pairs of autosomes and one pair of sex chromosomes. A human female has two X chromosomes, while a male has one X chromosome and one Y chromosome.
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...
