Noncanonical NF-κB in Cancer

Area of Science:

• Molecular Biology
• Immunology
• Oncology

Background:

• The Nuclear Factor kappa B (NF-κB) pathway regulates immune responses.
• Two main pathways exist: canonical and noncanonical NF-κB.
• The noncanonical NF-κB pathway is increasingly recognized for its role in cancer.

Purpose of the Study:

• To review the noncanonical NF-κB pathways.
• To discuss their protumorigenic roles in various cancer types.
• To explore NF-κB-independent functions and pathway crosstalk.

Main Methods:

• Literature review of noncanonical NF-κB signaling.
• Analysis of studies on NF-κB components in cancer.
• Examination of crosstalk between canonical and noncanonical pathways.

Main Results:

• Noncanonical NF-κB signaling components have protumorigenic effects in many cancers.
• Some components exhibit NF-κB-independent functions.
• Significant crosstalk exists between canonical and noncanonical NF-κB pathways.

Conclusions:

• The noncanonical NF-κB pathway is a key driver of oncogenesis.
• Understanding the full NF-κB regulatory network is essential for cancer therapy development.
