NF-kappaB: a stress-regulated switch for cell survival

Area of Science:

• Molecular Biology
• Immunology
• Oncology

Background:

• Nuclear factor-kappaB (NF-kappaB) is a transcription factor crucial for inflammatory and innate immune responses.
• NF-kappaB activation regulates genes involved in inflammation, cell adhesion, and immune signaling.
• NF-kappaB is implicated in oncogenesis, controlling cell proliferation, migration, cell cycle, and apoptosis.

Purpose of the Study:

• To review the role of NF-kappaB in cancer development and treatment resistance.
• To explore the therapeutic potential of NF-kappaB inhibitors in malignancies.
• To highlight NF-kappaB as a target for enhancing conventional cancer therapies.

Main Methods:

• Review of existing scientific literature on NF-kappaB signaling in cancer.
• Analysis of studies investigating NF-kappaB activation in chemoresistant and radioresistant cancer cells.
• Examination of research on selective IkappaB kinase inhibitors.

Main Results:

• Constitutive NF-kappaB activation is observed in various cancers, including hematological and epithelial malignancies.
• NF-kappaB activation in cancer cells can confer resistance to apoptosis induced by chemotherapy and radiation.
• Selective NF-kappaB inhibitors demonstrate potent induction of apoptosis in chemoresistant lymphoid malignancies.

Conclusions:

• Targeting NF-kappaB signaling presents a promising strategy to overcome cancer treatment resistance.
• Development of selective NF-kappaB inhibitors could sensitize tumor cells to apoptosis.
• NF-kappaB inhibitors may enhance the efficacy of conventional anticancer drugs across a broad range of malignancies.
