Liver Regeneration

Liver Regeneration

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 large...

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

Cirrhosis II: Pathophysiology

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...

Mechanism of Angiogenesis

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Diseases of the Liver and Gallbladder

Diseases of the Liver and Gallbladder

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 related to...

Cirrhosis I: Introduction

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Hepatology
Vascular Biology
Oncology

Background:

Angiogenesis and disrupted liver vasculature are implicated in chronic liver disease progression, leading to cirrhosis and hepatocellular carcinoma (HCC).
These vascular changes increase hepatic resistance and portal hypertension while reducing liver cell perfusion.
Angiogenesis also influences collateral formation and splanchnic blood flow, contributing to cirrhosis complications.

Purpose of the Study:

To review the molecular mechanisms of liver angiogenesis.
To summarize the consequences of angiogenesis in chronic liver disease.
To present strategies for counteracting excessive angiogenesis in experimental models for preventing cirrhosis, portal hypertension, and treating HCC.

Main Methods:

Literature review of molecular mechanisms of liver angiogenesis.
Analysis of the role of angiogenesis in chronic liver disease progression.
Summary of experimental strategies targeting angiogenesis.

Main Results:

Angiogenesis is crucial for liver vascular architecture disruption, cirrhosis development, and HCC growth.
It plays a role in portal-systemic collateral formation and splanchnic hyperemia, exacerbating cirrhosis complications.
Interfering with angiogenesis may prevent HCC development and progression.

Conclusions:

Understanding liver angiogenesis mechanisms is key to managing chronic liver diseases.
Targeting angiogenesis offers potential therapeutic strategies for preventing cirrhosis, portal hypertension, and treating HCC.
