Aurora B Antibody Immunohistochemistry on an FFPE Lung Adenocarcinoma Tissue
|Intended Use||For In Vitro Diagnostic Use|
|Summary and Explanation|
Aurora B kinase, a 39.3 kDa sized serine-threonine kinase, is a member of the Aurora family of mitotic kinases. The enzymatic activity of Aurora B kinase prevents stable kinetochore-microtubule attachments in early mitosis and promotes stabilization of the attachments in later mitosis due to low activity. The gene for Aurora B kinase (AURKB) is located on chromosome 17p13.1.
Abnormal expression of Aurora B antibody has been found in many cancer types, such as Non-Small Cell Lung Carcinoma, Mesothelioma, Glioblastoma, Oral Cancer and Hepatocellular Carcinoma. In Prostate and Colorectal Cancer, Aurora B expression directly correlates with the progression of cancer. In a study investigating the expression of Aurora B kinase in Thyroid Carcinoma, abundant expression of Aurora B kinase was detected in Anaplastic Carcinomas via IHC. A higher expression of Aurora B kinase in Anaplastic Thyroid Cancer than in differentiated Thyroid Cancer therefore suggests its use as a prognostic marker. In another immunohistochemical analysis, Aurora B antibody showed nuclear overexpression in high Gleason-grade Prostate Cancer, compared to low and intermediate grade cases. Additionally, there are numerous studies that indicate the use of Aurora B kinase as a prognostic marker in Ovarian Cancer. A study found that Aurora-B expression was correlated with the proliferation index (P < 0.001) and p53 expression (P = 0.014) in Breast cancer tissues and its expression was associated with lymph node metastasis (P = 0.002) and histological grade (P = 0.001). In conclusion, elevated Aurora-B expression in Breast Cancer patients contributes to chemoresistance and predicts poor prognosis.
