Sekundär-intraokulare (metastatische)Tumoren der Uvea
… rabbits with secondary intraocular (metastatic) uveal tumours will be subject to a histological revision. These 31 specimens have been taken out of an overall pool of 3342 histological eye specimens, which were sent in to GSF Institute of Pathology between 1974 - 2003.

Pharmacological Characterization of Prejunctional Serotonin Receptors in Mammalian Anterior Uvea
Serotonin (5-hydroxytiyptamine, 5-HT) and its receptors have been demonstrated in ocular tissues including the cornea, iris-ciliary body and retina of various species. The overall objective of the present study was two-fold: (a) to examine the effect of exogenous 5-HT on the release of radiolabeled …

Effect of Hydrogen Sulfide Donors on Sympathetic Neurotransmission and Intraocular Pressure of the Eye
… sympathetic neurotransmission in the anterior uvea in the eye and reducing IOP. There is evidence that decrease in levels of norepinephrine (NE), the major sympathetic neurotransmitter causes relaxation of pre-contracted iris muscles that increases space between the trabecular meshwork. This …

Establishment of MITF and TAZ as major determinants of uveal melanoma
Uveal melanoma (UM) is a cancer that arises from transformed melanocytes that exist in the uvea of the eye. Although UM is relatively rare, it is extremely deadly, due to the lack of treatment options for the metastatic disease. In contrast, cutaneous melanoma (CM), which is derived from …

Oncogenic mutation of GNAQ/11 disrupts melanocyte biology in a Zebrafish model of uveal melanoma
Uveal melanoma (UM) is the most common primary intraocular cancer in humans. These tumors arise from nonclassical melanocytes found in the choroid, iris, and ciliary body (collectively called the uvea). Over 80% of UM tumors contain activating mutations in one of two genes encoding the homologous …
