Insights

Nuclear factor-erythroid 2 p45-related factor 2 (NRF2) regulates cellular defense against stress. Its dual role in disease and cancer highlights the therapeutic potential of nuclear receptor-mediated NRF2 inhibition.

Area of Science:

  • Molecular Biology
  • Cellular Biology
  • Oncology

Background:

  • Nuclear factor-erythroid 2 p45-related factor 2 (NRF2) is a transcription factor crucial for cellular defense against oxidative and electrophilic stress.
  • NRF2 activation is explored for treating oxidative stress-related diseases and cancer prevention, but its constitutive activation in tumors promotes cancer cell survival and therapy resistance.

Purpose of the Study:

  • This review provides an overview of the NRF2 signaling pathway and its involvement in carcinogenesis.
  • It introduces the concept of NRF2 inhibition by nuclear receptors and discusses its biological significance in health and disease.
  • The review further explores the potential impact of nuclear receptor-mediated NRF2 inhibition on cancer therapy.

Main Methods:

  • Literature review of NRF2 signaling pathway.
  • Analysis of NRF2's role in carcinogenesis.
  • Examination of nuclear receptor-mediated inhibition of NRF2.
  • Discussion of biological significance and therapeutic implications.

Main Results:

  • NRF2 is a key regulator of antioxidant response genes.
  • Constitutive NRF2 activation contributes to cancer progression and treatment resistance.
  • Nuclear receptors can inhibit NRF2 activity.
  • Regulation of NRF2 by nuclear receptors has implications for both health and disease.

Conclusions:

  • NRF2 plays a complex role in cancer, acting as both a protective factor and a driver of tumor growth.

Transducer Mechanism: Nuclear Receptors

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:

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.

Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

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...
