Objective: To find out whether Casein Kinase 2 (CK2) and Survivin co-express and correlate in prostate as well as in breast cancer.
Study Design: A cross sectional analytical study.
Place and Duration of Study: Study was done at Army Medical College and in collaboration with Armed Forces Institute of Pathology (AFIP). The duration of this research was two years.
Material and Methods: The research was authorized by the Ethical Committee of AFIP. CK2 expression was determined by immunohistochemistry in paraffin embedded tissues from established patients of prostate cancer (n=30) and breast adenocarcinoma (n=30). Correlation of CK2 with Survivin was evaluated. Data were analyzed through SPSS version 20. For studying the correlation between the two proteins, pearson correlation coefficient was calculated. Data was considered at p-value ≤0.05.
Results: An expressively strong and affirmative correlation was found among expression of total CK2 and total Survivin in invasive along with non-invasive cases of both prostate and breast cancers. A significantly strong and positive correlation was found between nuclear CK2 and Survivin expression in non-invasive cases of prostate cancer and invasive as well as non-invasive cases of breast cancer. A significantly strong and positive correlation was found only between cytoplasmic CK2 and Survivin expression in non-invasive cases of prostate cancer.
Conclusion: CK2 and Survivin expressions have strong and positive correlation in both prostate and breast cancer particularly in non-invasive stage of the cancer.
