NF-kappaB: Two Sides of the Same Coin

Area of Science:

• Molecular Biology
• Immunology
• Oncology

Background:

• Nuclear Factor-kappa B (NF-κB) is a crucial transcription factor family regulating genes involved in survival, inflammation, and immune responses.
• Constitutive NF-κB expression is linked to various cancers, with microorganisms contributing to its activation in tumors.
• The NF-κB signaling pathway is increasingly recognized for its role in cancer development and progression.

Purpose of the Study:

• To review the multifaceted roles of NF-κB in both promoting and inhibiting tumor processes.
• To explore the impact of NF-κB on immune cells within the tumor microenvironment.
• To discuss the potential of NF-κB as a therapeutic target, particularly in the context of cancer immunotherapy.

Main Methods:

• Literature review of recent reports on NF-κB signaling in cancer.
• Analysis of NF-κB's dual role in cancer cells and immune cells.
• Examination of NF-κB's relevance to current cancer immunotherapy strategies.

Main Results:

• NF-κB exhibits contrasting functions, acting as both a pro-tumor and anti-tumor regulator.
• NF-κB influences immune cells, affecting their capacity to promote or suppress tumor development.
• The pathway's activity is implicated in the efficacy of cancer immunotherapies.

Conclusions:

• NF-κB is a significant factor in cancer biology with complex roles.
• Understanding NF-κB's interplay with the immune system is vital for cancer treatment.
• Targeting NF-κB presents a promising therapeutic avenue for cancer patients.
