Overview
Cognitive Dissonance01:38

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

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.

The Central Dogma

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Summary
This summary is machine-generated.

Selective COX-2 inhibitors offer improved gastrointestinal safety compared to NSAIDs. However, the scientific basis of the "COX dogmas" supporting their marketing success is now being challenged by new research.

Area of Science:

  • Pharmacology
  • Gastroenterology
  • Drug Development

Background:

  • Selective cyclooxygenase 2 (COX-2) inhibitors achieved significant market success.
  • Their success was attributed to comparable efficacy to NSAIDs and improved gastrointestinal safety.

Purpose of the Study:

  • To examine the scientific basis of the widely accepted
  • COX-1 dogma
  • and
  • COX-2 dogma
  • .

Main Methods:

  • The study critically reviews existing experimental data.
  • It challenges the established understanding of COX-1 and COX-2 roles.

Main Results:

  • The marketing success of COX-2 inhibitors was heavily reliant on simplified messaging regarding COX-1 and COX-2 functions.
  • Recent experimental findings cast doubt on the scientific foundation of these
  • dogmas
  • .

Conclusions:

  • While COX-2 inhibitors have benefited patients, their underlying scientific rationale is increasingly questioned.
  • Further research is needed to fully understand the roles of COX enzymes and the implications for drug development.
