Summary
Epigenetics influences human diseases, but environmental impact on DNA methylation is debated. We found a POMC gene hypermethylation variant in obese children, linked to primate-specific Alu elements.
Area of Science:
- Epigenetics and Human Disease
- Genetics and Environmental Factors
Background:
- Extensive research has explored epigenetics' role in human diseases.
- A debate persists regarding environmental factors influencing DNA methylation patterns.
- DNA methylation defects are linked to imprinting diseases and cancer, but impact on common diseases like obesity is unclear.
Purpose of the Study:
- To investigate the role of DNA methylation in obesity.
- To examine the relationship between POMC gene methylation and obesity in children.
- To explore the influence of transposable elements on DNA methylation and disease development.
Main Methods:
- Observational study of obese children.
- Analysis of POMC gene methylation patterns.
- Phylogenetic analysis to assess the relationship with Alu elements.
Main Results:
- A hypermethylation variant of the POMC gene was observed in obese children.
- The POMC gene plays a crucial role in body weight regulation.
- Phylogenetic analyses indicated a link between POMC DNA methylation and primate-specific Alu elements.
Conclusions:
- Obesity in children may be associated with POMC gene hypermethylation.
- Transposable elements, like Alu elements, may influence DNA methylation patterns.
- Further research is needed to elucidate the impact of epigenetics on common diseases like obesity.

01:24Obesity
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
01:27The Periodic Table and Organismal Elements
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.

01:21Dimensions of Health and Illness
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.
01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
