Cell Specific Gene Expression01:58

Cell Specific Gene Expression

13.4K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Overview of Lipid Metabolism

930
Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Liver Regeneration

3.2K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

122
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

33.1K
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...

Area of Science:

  • Hepatology
  • Molecular Biology
  • Genetics

Background:

  • Metabolic dysfunction-associated steatohepatitis (MASH) is a progressive liver disease with potential to cause cirrhosis and liver cancer.
  • The exact pathogenesis of MASH remains unclear, but multifactorial influences including genetics, environment, and lifestyle are implicated.
  • Emerging evidence highlights the critical role of epigenetic modifications in MASH development and progression.

Purpose of the Study:

  • To review current research on the epigenetic mechanisms underlying MASH.
  • To explore the role of epigenetic factors as mediators between pathogenic factors and MASH.
  • To identify potential epigenetic-based therapeutic strategies for MASH.

Main Methods:

  • Literature review of studies investigating epigenetic modifications in MASH.
  • Analysis of the roles of chromatin structure, DNA methylation, histone modification, and non-coding RNAs.
  • Synthesis of research progress in the epigenetics of MASH.

Main Results:

  • Epigenetic changes, such as alterations in chromatin structure and accessibility, are significantly associated with MASH.
  • DNA methylation, histone modifications, and non-coding RNAs are identified as key epigenetic regulators in MASH pathogenesis.
  • These epigenetic factors act as crucial links between environmental/lifestyle factors and the development of MASH.

Conclusions:

  • Epigenetics plays a pivotal role in the initiation and advancement of MASH.
  • Understanding these epigenetic alterations is crucial for developing targeted therapies.
  • Further investigation into epigenetic mechanisms promises novel therapeutic avenues for MASH patients.
