Liver Regeneration

3.4K
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...

Liver Physiology

1.5K
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...

Diseases of the Liver and Gallbladder

1.1K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

  • Somatic genome editing presents a novel therapeutic strategy for genetic cardiovascular conditions.

Purpose of the Study:

  • To review recent advancements in somatic genome editing for cardiovascular disease.
  • To highlight novel gene editing technologies and delivery systems.
  • To explore potential liver-targeted therapeutic strategies.

Main Methods:

  • Review of recent literature on somatic genome editing techniques.
  • Analysis of gene editing approaches including disruption, homology-directed repair, and base editing.
  • Evaluation of viral and non-viral delivery systems for liver-directed gene editing.

Main Results:

  • Successful gene modification in hepatocytes demonstrated in model organisms.
  • Significant reductions in plasma cholesterol and triglyceride levels observed.
  • Precise gene editing achieved, addressing key cardiovascular targets.
  • Improved delivery systems mitigate safety concerns and enhance efficacy.
