DNA damage-induced nuclear factor-kappa B activation and its roles in cancer progression

Area of Science:

• Molecular Biology
• Cellular Biology
• Genomics

Background:

• DNA damage poses a significant threat to cellular homeostasis and genomic stability.
• Cellular responses to DNA damage (DDR) are critical for cell survival, and their failure can lead to aging and cancer.
• Nuclear Factor-kappa B (NF-κB) is a key transcription factor involved in cellular stress responses and DDR.

Purpose of the Study:

• To summarize recent advancements in understanding DNA damage response (DDR) and NF-κB signaling pathways.
• To focus on the DNA damage-induced NF-κB signaling cascade and its role in B cell development and cancer therapeutic resistance.
• To discuss strategies for targeting genotoxic NF-κB signaling to overcome cancer treatment resistance.

Main Methods:

• Literature review and synthesis of current research on DNA damage response.
• Analysis of NF-κB signaling pathways in the context of cellular stress and DNA damage.
• Exploration of the physiological and pathological significance of NF-κB in B cell development and cancer.

Main Results:

• NF-κB, alongside p53, regulates numerous genes involved in DNA damage response.
• DNA damage can induce NF-κB signaling, impacting cellular processes.
• The NF-κB pathway is implicated in B cell development and the development of resistance to cancer therapies.

Conclusions:

• Understanding the DNA damage-induced NF-κB signaling cascade is crucial for comprehending cellular homeostasis and disease pathogenesis.
• Targeting genotoxic NF-κB signaling presents a promising strategy to combat acquired resistance and resensitize cancer cells to cytotoxic treatments.
• Further research into selective NF-κB targeting could lead to novel therapeutic approaches for refractory cancers.
