Epigenetic silencing of serine protease HTRA1 drives polyploidy.

Background: Increased numbers and improperly positioned centrosomes, aneuploidy or polyploidy, and chromosomal instability are frequently observed characteristics of cancer cells. While some aspects of these events and the checkpoint mechanisms are well studied, not all players have yet been identified. As the role of proteases other than the proteasome in tumorigenesis is an insufficiently addressed question, we investigated the epigenetic control of the widely conserved protease HTRA1 and the phenotypes of deregulation.

Comparing the Prognostic Value of BAP1 Mutation Pattern, Chromosome 3 Status, and BAP1 Immunohistochemistry in Uveal Melanoma.

Uveal melanoma (UM), a tumor of the eye, can be divided into 2 major classes correlating with patients' prognosis. Gene expression profiles and chromosome 3 status are correlated with tumor classification and prognosis. Somatic BAP1 mutations are another feature largely restricted to metastatic UM.

BAP1 germline mutation in two first grade family members with uveal melanoma.

Background: Uveal melanoma (UM) is the most common primary cancer of the eye in adults. About half of the patients are at risk of developing metastatic disease resulting in a poor clinical prognosis. Metastatic progression is strongly associated with loss of one chromosome 3 in the tumour (monosomy 3).
