Liver Regeneration01:24

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...

Liver Physiology01:30

Liver Physiology

388
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

355
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...

Liver Histology01:27

Liver Histology

443
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

56
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Area of Science:

  • Biochemistry
  • Genetics
  • Hepatology

Background:

  • Pyruvate kinase (PK) is a key enzyme in hepatic glucose metabolism.
  • The gene pyruvate kinase liver/red blood cells (PKLR) encodes PK.
  • PKLR is implicated in liver diseases like metabolic dysfunction-associated steatotic liver disease (MASLD) and hepatocellular carcinoma (HCC).

Purpose of the Study:

  • To review the critical role of PKLR in MASLD and HCC progression.
  • To examine the effects of PKLR modulation in vitro and in vivo.
  • To discuss therapeutic strategies targeting PKLR for liver diseases.

Main Methods:

  • Systems biology approaches: metabolic and gene co-expression network analyses.
  • Genome-wide association studies (GWAS).
  • In vitro and in vivo experimental models to assess PKLR modulation.

Main Results:

  • PKLR identified as a pivotal gene influencing liver metabolism in MASLD and HCC.
  • PKLR modulation affects liver disease progression.
