Insights

The nuclear factor kappa B (NF-κB) pathway is implicated in cancer development and progression. Targeting NF-κB shows promise for cancer prevention and treatment strategies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Immunology

Background:

  • The nuclear factor kappa B (NF-κB) signaling pathway, including RelA and c-Rel, has been linked to tumorigenesis.
  • Oncogenic mutations in NF-κB proteins and persistent activation in solid tumors suggest its role in cancer.
  • The IκB-kinase complex is an upstream activator of the NF-κB pathway.

Purpose of the Study:

  • To review molecular evidence on the functions of NF-κB in various tumor stages.
  • To support the rationale for targeting NF-κB in cancer prevention and therapy.

Main Methods:

  • Utilizing conditional knockout mice for tissue-specific targeting of NF-κB pathway components.
  • Genetically testing cell-autonomous and non-autonomous functions of NF-κB.
  • Reviewing molecular evidence from various studies.

Main Results:

  • NF-κB plays diverse roles throughout different stages of cancer development.
  • Conditional knockout models enable functional studies of NF-κB in cancer.
  • Evidence supports NF-κB's involvement in both inflammation-associated and sporadic cancers.

Conclusions:

  • The NF-κB pathway is a critical regulator in tumorigenesis.
  • Targeting the NF-κB pathway presents a viable strategy for cancer prevention and therapy.

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.

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...
Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
