NF-κB pathways in hematological malignancies.

Area of Science:

• Molecular Biology
• Immunology
• Oncology

Background:

• Nuclear factor kappa B (NF-κB) is a transcription factor family vital for cellular functions including immunity, inflammation, and survival.
• Constitutive activation of NF-κB is a hallmark of many cancers, significantly contributing to tumorigenesis.

Purpose of the Study:

• To review the canonical and non-canonical NF-κB pathways.
• To elucidate the role of NF-κB subunits in immune cell development and function.
• To examine the relevance of NF-κB in various hematological malignancies and its interaction with apoptotic pathways.

Main Methods:

• Literature review of NF-κB pathways and their involvement in cellular processes.
• Analysis of NF-κB subunit roles in B cells, T cells, macrophages, and dendritic cells.
• Discussion of NF-κB interactions with TRAIL and p53-mediated apoptosis.

Main Results:

• NF-κB has two main pathways: canonical (RelA/p50) and non-canonical (RelB/p50 or RelB/p52).
• NF-κB plays a significant role in the pathogenesis of hematological malignancies like leukemias, lymphomas, and multiple myeloma.
• NF-κB interacts with apoptotic pathways, influencing cancer cell survival and death.

Conclusions:

• Understanding NF-κB pathways is critical for comprehending hematological malignancies.
• Therapeutic strategies targeting NF-κB offer potential for anti-tumoral mono- or combination therapies.
• Blocking NF-κB activity and inducing apoptosis are key goals for novel cancer treatments.
