NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

7.6K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

1.8K
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.

Esophageal Strictures-I: Introduction

1.3K
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Barrett Esophagus-II: Clinical Manifestations and Management

1.8K
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

2.6K
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Area of Science:

  • Gastroenterology
  • Molecular Biology
  • Cell Biology

Background:

  • The esophageal stratified squamous epithelium provides a critical protective barrier.
  • Defects in this barrier function are implicated in gastroesophageal reflux disease (GERD).
  • GERD involves damage to the esophageal epithelium from gastrointestinal refluxate exposure.

Purpose of the Study:

  • To review the involvement of NFkB and Nrf2 in maintaining esophageal epithelial barrier function.
  • To elucidate the molecular mechanisms underlying GERD pathogenesis.
  • To identify potential therapeutic targets for improving GERD clinical outcomes.

Main Methods:

  • Literature review of studies investigating NFkB and Nrf2 pathways in esophageal epithelium.
  • Analysis of molecular signaling cascades related to epithelial barrier integrity.
  • Synthesis of current knowledge on the role of these pathways in GERD.

Main Results:

  • NFkB and Nrf2 play significant roles in regulating esophageal epithelial barrier function.
  • Dysregulation of these pathways contributes to the epithelial damage observed in GERD.
  • Specific molecular interactions of NFkB and Nrf2 influence barrier integrity.

Conclusions:

  • Understanding NFkB and Nrf2 pathways is crucial for comprehending GERD.
  • Targeting these molecular pathways may offer novel therapeutic strategies for GERD.
  • Further research into these pathways can lead to improved patient outcomes in GERD.
