MicroRNAs in NF-kappaB signaling

Area of Science:

• Molecular Biology
• Genetics
• Immunology

Background:

• Nuclear factor κB (NF-κB) controls genes vital for immunity, inflammation, and cancer.
• MicroRNAs (miRNAs) are small RNAs that regulate gene expression by targeting messenger RNAs.
• Dysregulation of both NF-κB and miRNAs is observed in various human diseases, especially cancer.

Purpose of the Study:

• To review the convergence of miRNA and NF-κB signaling pathways.
• To discuss the role of miRNA and NF-κB dysregulation in human diseases, with a focus on cancer.
• To highlight specific miRNAs (miR-146, miR-155, miR-181b, miR-21, miR-301a) involved in NF-κB activation and tumorigenesis.

Main Methods:

• Literature review of scientific publications.
• Analysis of the functional roles of specific miRNAs in NF-κB signaling.
• Discussion of the pathological contributions of miRNA-NF-κB interactions in cancer.

Main Results:

• miRNAs significantly impact NF-κB activation and signaling.
• Specific miRNAs (e.g., miR-146, miR-155) play crucial roles in modulating NF-κB activity.
• Aberrant miRNA and NF-κB interactions are linked to the development and progression of various cancers.

Conclusions:

• Understanding the complex interplay between miRNAs and NF-κB is essential for comprehending immune system regulation.
• Deciphering the pathological roles of miRNAs in NF-κB dysregulation offers therapeutic potential for cancer treatment.
• Targeting miRNA-NF-κB pathways may lead to novel strategies for managing immune-related disorders and malignancies.
