We report significant increase in expression of two differentially expressed proteins, namely, A-Raf and Fatty Acid 2- Hydroxylase (FA2H), at early stage of HCC initiation, during its progression and at tumor stage.
We provide the first description of kinase fusions in systemic histiocytic neoplasms and activating ARAF and MAP2K1 mutations in non-Langerhans histiocytic neoplasms.
The Raf family kinases (A-Raf, B-Raf and C-Raf) have been intensively studied since being identified in the early 1980s as retroviral oncogenes, especially with respect to the discovery of activating mutations of B-Raf in a large number of tumors which led to intensified efforts to develop drugs targeting Raf kinases.
To further define the role of this pathway in the development of high-grade gliomas, we used the established RCAS/TVA glioma mouse model to test the ability of activated MAPK/extracellular signal-regulated kinase (ERK) kinase (MEK), a RAF effector, to induce tumors in vivo in the context of activated AKT or Ink4a/Arf loss.
