While AURKA Phe31Ile (1712T>A) and AURKBThr298Met (893G>A) showed no association, the synonymous AURKB Ser295Ser (885A>G) polymorphism resulted in an increased breast cancer risk for carriers of the homozygous 885G genotype (OR=1.45, 95% CI=1.05-2.0, P=0.02).
Inhibition of Aurora kinase B has been evaluated as a therapy to block solid tumor growth in breast cancer, hepatocellular carcinoma, lung adenocarcinoma, and colorectal cancer models.
We also investigated the relationship between AURKB and survival rate in BRCA as well as reversine to Aurora kinase expression in BCRA cell lines, including TNBC subtype, 4T1, MDA-MB-231, and luminal subtype MCF-7.
This work helps elucidate molecular mechanisms of breast cancer health disparity and identifies putative biomarkers and therapeutic targets such as resistin, and the aurora B and polo-like kinase signaling pathways for treating AA breast cancer patients.
