摘要：

CK2 is a highly conserved protein serine/threonine kinase that is ubiquitously distributed in eukaryotes, constitutively active and has been implicated in multiple cellular functions, as well as in tumorigenesis and transformation. Elevated CK2 activity has been associated with the malignant transfort-nation of several tissues and is associated with aggressive tumor behaviour. While the precise roles of CK2 in tumorigenesis remain incompletely understood, mounting evidence suggests a role for CK2 in the protection of cells from apoptosis via the regulation of tumor suppressor and oncogene activity. Consequently, CK2 has emerged as a potential therapeutic target, and strategies to inhibit CK2 have been ongoing in pre-clinical trials. This review will focus on published evidence highlighting the molecular mechanisms by which CK2 functions in the promotion of tumorigenesis, as well as review current strategies being used to inhibit CK2.
