Cell Specific Gene Expression01:58

Cell Specific Gene Expression

13.3K
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...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

271
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Epigenetic Regulation

3.5K
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.

Liver Physiology

3.8K
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Area of Science:

  • Epigenetics and its role in cellular regulation and disease pathology.

Background:

  • Epigenetic processes (DNA methylation, histone modification, chromatin remodeling, noncoding RNAs) regulate gene expression and cell phenotype in response to environmental factors.
  • These mechanisms are crucial for understanding complex chronic diseases and developing novel diagnostic and prognostic tools.

Purpose of the Study:

  • To review the molecular basis of epigenetics.
  • To detail the influence of epigenetic mechanisms on liver physiology and diseases, including cancer, fibrosis, and nonalcoholic steatohepatitis.
  • To discuss current limitations and future possibilities in epigenetic profiling and therapeutics for liver disease.

Main Methods:

  • Review of existing literature on epigenetic regulatory processes.
  • Detailed examination of epigenetic mechanisms in the context of liver physiology and disease.
  • Discussion of limitations and potential of epigenetic profiling and therapeutics.

Main Results:

  • Epigenetic modifications are plastic and responsive to environmental cues, offering potential for therapeutic interventions and lifestyle advice.
  • Specific epigenetic mechanisms influence liver cancer, fibrosis, and nonalcoholic steatohepatitis.
  • Environmental-induced epigenetic changes may be stable and heritable.

Conclusions:

  • Epigenetic insights are vital for the future management and care of liver diseases.
  • Hepatologists should be informed about emerging epigenetic concepts relevant to patient care.
