RESUMEN
Breast cancer (BC) is the second most fatal disease and is the prime cause of cancer allied female deaths. BC is caused by aberrant tumor suppressor genes and oncogenes regulated by transcription factors (TFs) like NF-κB. NF-κB is a pro-inflammatory TF that crucially alters the expressions of various genes associated with inflammation, cell progression, metastasis, and apoptosis and modulates a network of genes that underlie tumorigenesis. Herein, we focus on NF-κB signaling pathways, its regulators, and the rationale for targeting NF-κB. This review also includes TFs that maintain NF-κB crosstalk and their roles in promoting angiogenesis and metastasis. In addition, we discuss the importance of combination therapies, resistance to treatment, and potential novel therapeutic strategies including nanomedicine that targets NF-κB.

BACKGROUND: Breast cancer (BC) accounts for one of the most prevalent malignancies in the world. Inflammatory molecules modulate tumor microenvironment in BC that promotes tumor growth and metastasis. NF-κB (a transcription factor) that regulates multiple immune functions and acts as a crucial mediator of inflammatory responses. OBJECTIVE: The present study is aimed to quantitatively summarize the relation of NFKB1-94 ATTG (I, insertion/D, deletion) variant and risk of BC. METHODS: Further, the meta-analysis includes three independent case-control investigations that focus on NFKB1-94, ATTG I/D polymorphism, and BC patients. Web of Science, PubMed and Embase databases were used to retrieve relevant data. OR and 95% confidence interval of pooled studies were analyzed by using the MetaGenyo web tool. RESULTS: This study revealed a high heterogeneity. In all three genetic comparison models, the NFKB1-94 ATTG I/D variant is not related to the risk of BC. Further, no publication bias on the connection between NFKB1-94 ATTG I/D variant and risk of BC was observed. CONCLUSION: To summarize, our meta-analysis demonstrates that the NFKB1-94 ATTG I/D polymorphism is not a major risk factor for BC.
