Insights

The transcription factor NRF2 plays a vital role in cancer prevention. Activating NRF2 in cells may help delay or prevent certain cancers, potentially extending lifespan.

Area of Science:

  • Molecular biology
  • Oncology
  • Biochemistry

Background:

  • The transcription factor NRF2 (NF-E2-related factor 2) is a master regulator of cytoprotective genes.
  • NRF2 activity is crucial for maintaining cellular homeostasis in metabolically active organs.
  • Dysregulation of NRF2 is implicated in various pathological conditions, including cancer.

Purpose of the Study:

  • To review current research on NRF2's role in cancer development.
  • To highlight findings from in vivo studies using NRF2 knockout mice.
  • To explore the interplay between NRF2, calorie restriction, and chemoprevention.

Main Methods:

  • Literature review of in vivo studies focusing on NRF2 function.
  • Analysis of NRF2 knockout mouse models in the context of cancer.
  • Examination of the impact of calorie restriction on cancer development and NRF2 activity.

Main Results:

  • NRF2 is essential for chemoprevention, as evidenced by reduced cancer protection in NRF2 knockout mice.
  • Calorie restriction's cancer-protective effects appear to be largely mediated by NRF2.
  • NRF2 knockout mice show diminished protection against carcinogenesis, particularly under calorie restriction.

Conclusions:

  • NRF2 is a critical factor in the body's defense against cancer.
  • Targeting NRF2 activation in somatic cells presents a promising strategy for cancer prevention.
  • NRF2-mediated pathways could lead to delayed cancer onset and extended healthspan.

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.

Transducer Mechanism: Nuclear Receptors01:31

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:
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
