Cell Specific Gene Expression01:58

Cell Specific Gene Expression

13.6K
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...

Protein Import into the Peroxisomes01:27

Protein Import into the Peroxisomes

3.4K
Cells contain membrane-bound organelles called peroxisomes that oxidize organic molecules by transferring hydrogen atoms to oxygen, producing hydrogen peroxide. Peroxisomes enzymatically convert the released hydrogen peroxide into water and oxygen.
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

153
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...

Cystic Fibrosis: Pathogenesis

202
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

86
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:

  • Molecular Biology
  • Hepatology
  • Genetics

Background:

  • Advances in molecular biology have identified genes and mutations causing cholestasis.
  • Mechanisms of bile formation and circulation are now better understood.

Purpose of the Study:

  • To classify the genetic causes of cholestasis based on biliary secretion biology.
  • To provide pediatricians with a diagnostic framework for childhood cholestasis.

Main Methods:

  • Physiopathological classification of cholestasis based on molecular and cellular mechanisms.
  • Categorization includes membrane transport, vesicle transit, permeability, nuclear receptors, cholangiopathies, and hepatocellular diseases.

Main Results:

  • A comprehensive classification of genetic cholestasis causes has been established.
  • The classification addresses transport abnormalities, intracellular processes, and genetic mutations.

Conclusions:

  • This physiopathological classification aids in the early diagnosis and management of chronic cholestasis in children.
  • Timely referrals and treatment are crucial for managing cholestasis complications.
