Mutations in the NF-kappaB signaling pathway: implications for human disease

Area of Science:

• Molecular Biology
• Genetics
• Immunology

Background:

• The nuclear factor-kappa B (NF-kappaB) signaling pathway is crucial for regulating genes involved in cell proliferation, survival, stress response, immunity, and inflammation.
• Dysregulation of the NF-kappaB pathway is implicated in numerous human and animal diseases, particularly those linked to chronic inflammation, immunodeficiency, and cancer.

Purpose of the Study:

• To review human diseases associated with mutations in core NF-kappaB signaling pathway components.
• To discuss the molecular mechanisms by which these NF-kappaB alterations contribute to disease pathology.

Main Methods:

• Review of human diseases linked to mutations in NF-kappaB pathway components.
• Analysis of molecular mechanisms underlying NF-kappaB signaling alterations in disease.
• Description of genetic diseases involving mutations in NF-kappaB modifiers, transducers, or regulatory elements.

Main Results:

• Mutations in NF-kappaB pathway components, including germline and somatic alterations (amplifications, point mutations, deletions, translocations), are implicated in various human diseases.
• Specific genes affected include REL, NFKB2, IKBA, CYLD, NEMO, and BCL-3.
• Diseases can also arise from mutations affecting protein modifiers, signal transducers, or NF-kappaB binding sites.

Conclusions:

• Genetic alterations in the NF-kappaB signaling pathway are significant contributors to human disease pathology.
• Understanding these mutations is key to elucidating mechanisms of diseases involving inflammation, immunity, and cancer.
• Further research into NF-kappaB pathway genetics can inform therapeutic strategies for related disorders.
