PURPOSE Brachytherapy is a well-established, effective treatment for uveal melanoma with a failure rate of 15%. The fatal consequence of unsuccessful treatments offers reason for improvement of the method. The authors propose using an apoptosis inducing agent locally, concomitantly with the well-established therapy, to sensitize the tumor cells. The authors(More)
In this short communication, it is shown that 4-thio-uridylate (s(4)UMP, designated as UD29) inhibits glyceraldehyde 3-phosphate dehydrogenase (GAPDH), suggesting that the enol-form of the thiolated nucleotide may interfere with the function of the essential -SH group in the active center of the enzyme. Since HIV entry requires thiol/disulfide exchange(More)
We have previously reported the in vitro anti-proliferative effect of 4-thio-uridylate (s(4)UMP) on OCM-1 uveal melanoma cells. Here, we assessed the efficacy of s(4)UMP on JY cells. Treatment of JY cells with s(4)UMP suppressed their colony forming activity and induced apoptosis; healthy human bone marrow granulocyte-macrophage progenitor cells were(More)
PURPOSE The identification of cells with properties of retinal progenitor cells (RPCs) in the adult human ciliary margin (CM) prompted a number of studies of their proliferative and differentiation potential. One of the remaining challenges is to find a feasible method of isolating RPCs from the patient's eye. In the human CM, only the iris pigment(More)
PURPOSE Failure of retinal pigment epithelial (RPE) cells and macrophages to engulf different dying cells in the retina may result in accumulation of debris and development of age-related macular degeneration (AMD). The dynamics and influence of different treatments on this clearance process can be studied in vitro using human ARPE-19 cells and macrophages(More)
Despite the growing evidence implicating intratumoural fibrin formation in the progression of malignant tumours, the origin of coagulation factors that participate in extravascular clotting has not been elucidated. Using immunohistochemical methods we attempted to detect and localize clotting factors of extrinsic pathway in different human malignant(More)
