NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

10.1K
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.

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

Transducer Mechanism: Nuclear Receptors

3.2K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Eukaryotic Transcription Inhibitors01:52

Eukaryotic Transcription Inhibitors

11.1K
Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

3.4K
Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Pharmacology

Background:

  • Nuclear factor erythroid 2 (NF-E2)-related factor (Nrf2) is a key regulator of the antioxidant response.
  • Nrf2 activation is a common therapeutic strategy for diseases driven by oxidative stress.
  • The precise role of Nrf2 in disease pathogenesis is complex and context-dependent.

Purpose of the Study:

  • To evaluate the dual role of Nrf2 in oxidative-stress-induced diseases.
  • To determine the conditions under which Nrf2 activation or inhibition is therapeutically beneficial.
  • To guide the development of targeted Nrf2-based therapies.

Main Methods:

  • Literature review of studies investigating Nrf2 in various disease models.
  • Analysis of experimental data on Nrf2 modulation in oxidative stress.
  • Comparative assessment of Nrf2 activation versus inhibition outcomes.

Main Results:

  • Nrf2 activation demonstrates protective effects in certain oxidative stress conditions.
  • Conversely, Nrf2 activation can exacerbate disease progression in other contexts.
  • The net effect of Nrf2 modulation is highly dependent on the specific disease and cellular environment.

Conclusions:

  • Nrf2 is a double-edged sword in oxidative-stress-induced diseases.
  • A nuanced approach is required, necessitating the determination of whether to activate or inhibit Nrf2 prior to therapeutic intervention.
  • Future Nrf2-targeted therapies must be personalized based on disease-specific Nrf2 activity.
