Mechanisms involved in pituitary tumorigenesis, especially of non-functional pituitary adenomas remain unclear. Various cell cycle inhibitors have been found to be underexpressed in pituitary tumors. However alterations of the G2/M checkpoint have not been revealed as a major player in the pathogenic process. Wee1 kinase, a nuclear protein that delays G2/M transition has been recently recognized as a tumor suppressor and has been found as a potential pathogenic factor in pituitary adenomagenesis. In this chapter after a brief summary of the cell cycle regulation, the biogenesis and function of miRs in pituitary adenomas, we review the role and function of Wee1 kinase focusing on its potential role in pituitary tumorigenesis. MicroRNAs posttranscriptionally regulating expression of Wee1 kinase and their expression and role in pituitary adenoma development are also discussed.
