Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.1K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

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...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

2.2K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Cells and Secretions of the Pancreas01:16

Cells and Secretions of the Pancreas

2.3K
The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...

Insulin Secretory Vesicles01:05

Insulin Secretory Vesicles

5.0K
Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

1.3K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are...

Summary

Beclin1 (Becn1) is crucial for pancreas development. Its loss causes severe defects in pancreatic growth and function, leading to neonatal death due to pancreatic agenesis.

Area of Science:

  • Developmental Biology
  • Molecular Biology
  • Genetics

Background:

  • Beclin1 (Becn1) is a key regulator of autophagy, membrane trafficking, and tumor suppression.
  • Its precise role in pancreas development has not been fully elucidated.

Purpose of the Study:

  • To investigate the function of Beclin1 in pancreas development and morphogenesis.
  • To determine the consequences of Becn1 loss in pancreatic cells.

Main Methods:

  • Generation of mice with conditional deletion of Becn1 in the pancreas using Ptf1a-Cre driver.
  • Analysis of pancreatic development, function, and survival rates in knockout mice.

Main Results:

  • Conditional deletion of Becn1 in the pancreas led to severe developmental defects.
  • Loss of Becn1 resulted in insufficient exocrine and endocrine pancreatic function.
  • Approximately 50% of mutant mice died postnatally, attributed to pancreatic agenesis.

Conclusions:

  • Beclin1 plays a novel and essential role in pancreas morphogenesis, differentiation, and growth.
  • Becn1 deficiency leads to pancreatic agenesis and neonatal lethality.
