Summary
Early-life environmental factors, not just diet and exercise, can program offspring for obesity across generations. Understanding these developmental programming mechanisms is key to combating the obesity pandemic.
Area of Science:
- Developmental biology
- Metabolic disorders
- Epigenetics
Background:
- The global obesity pandemic is linked to diet and lifestyle changes.
- Early-life environmental factors and developmental plasticity are underappreciated contributors to obesity.
- Altered maternal nutrition can lead to transgenerational transmission of metabolic disorders.
Purpose of the Study:
- To explore the role of developmental plasticity in obesity.
- To investigate the transgenerational transmission of metabolic disorders.
- To understand the mechanisms of developmental programming.
Main Methods:
- Review of human and animal studies on early-life environment and obesity.
- Analysis of evidence for transgenerational effects of developmental programming.
- Examination of potential epigenetic and non-genomic inheritance mechanisms.
Main Results:
- Early-life environmental perturbations can program offspring for lifelong obesity and metabolic disorders.
- Developmental programming effects can be transmitted across generations, even without continued stressors.
- Both maternal and paternal lineages may be involved in transgenerational phenotype transmission.
Conclusions:
- Developmental programming is a significant factor in the obesity crisis.
- Epigenetic inheritance and other mechanisms contribute to transgenerational effects.
- Further research into transmission mechanisms is crucial for public health interventions.

Genomic Imprinting and Inheritance
30.1K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Obesity
1.5K
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...

Human 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.
The complex relationship between genetics and psychology is observable through common biological components such...

Methods of Nuclear Reprogramming
1.4K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Epigenetic Regulation
3.4K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
