Summary

This summary is machine-generated.

Maternal chromium supplementation reduced offspring obesity by altering gene expression in adipose tissue. This nutritional strategy offers potential for preventing intergenerational metabolic disorders.

Area Of Science

  • Nutritional epigenetics
  • Metabolic disorders
  • Obesity research

Background

  • Maternal nutrition significantly impacts offspring metabolic health.
  • Chromium (Cr) plays a role in glucose and lipid metabolism.
  • Intergenerational obesity is a growing public health concern.

Purpose Of The Study

  • To elucidate the molecular mechanisms by which maternal chromium supplementation mitigates offspring obesity.
  • To identify key regulatory genes involved in chromium's protective effects.
  • To explore potential therapeutic targets for intergenerational obesity prevention.

Main Methods

  • Mice dams were supplemented with chromium (Cr) or control diets during gestation and lactation.
  • Offspring received Cr diets post-weaning until 32 weeks of age.
  • Adipose tissue gene expression was analyzed using GEO2R, functional enrichment, and protein-protein interaction network analysis.

Main Results

  • Chromium supplementation significantly reduced offspring adipose tissue mass.
  • 136 differentially expressed genes (DEGs) were identified in offspring adipose tissue.
  • DEGs were involved in lipid metabolism, steroid hormone biosynthesis, and fatty acid oxidation.
  • 14 hub genes, including ACSL1, DGAT1, and PPARG, were identified as central to adipocyte regulation and lipid accumulation suppression.

Conclusions

  • Maternal chromium supplementation protects against offspring obesity by modulating key genes involved in lipid metabolism.
  • The identified gene network provides a framework for developing nutritional and pharmacological interventions for obesity prevention.
  • Chromium's effects on epigenetic regulation of lipid metabolism are crucial for intergenerational metabolic health.

Genomic Imprinting and Inheritance 02:30

35.3K

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...

Epigenetic Regulation 01:37

3.1K

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.

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...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition 01:27

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Nondisjunction 01:21

4.1K

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers.  Nondisjunction is common during anaphase I or anaphase II of meiosis.  Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

Regulation of Food Intake 01:30

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
