    Modern Pathology 24(6):836 (2011) PMID 21441901 PMCID PMC3152794

    Aurora kinase A (AURKA), a serine/threonine kinase, has been shown to regulate the cell cycle checkpoint and maintain genomic integrity. AURKA is overexpressed in various carcinomas. Breast cancer 2, early onset (BRCA2) has an important role in maintaining genomic stability and acts as a tumor s...
  11. The biphasic role of NF-kappaB in progression and chemoresistance of ovarian cancer.

    Clinical Cancer Research 17(8):2181 (2011) PMID 21339307 PMCID PMC3152795

    NF-κB is a transcription factor known to promote tumorigenesis. However, NF-κB is also known to be proapoptotic and may potentially function as a tumor suppressor, although such a functional role has not been extensively investigated in human cancer. A dominant-negative mutant of IκBα with mutat...
