OBJECTIVE This study was undertaken to clone and express a recombinant human zona pellucida protein 3 and to characterize its biologic activities as a sperm ligand and an inducer of the acrosome reaction. STUDY DESIGN Human ovarian teratocarcinoma (PA-1) cells were transfected with an expression vector containing human zona pellucida protein 3(More)
Plasminogen activator inhibitor-1 (PAI-1) is the major and most specific acting urokinase (uPA) and tissue plasminogen activator (tPA) inhibitor. Apart from its function in the fibrinolytic system, PAI-1 was also found to contribute to processes like tissue remodelling, angiogenesis, and tumour progression. However, the role of PAI-1 in those processes(More)
The upstream stimulatory factor 2 (USF2) is a regulator of important cellular processes and is supposed to have also a role during tumor development. However, the knowledge about the mechanisms that control the function of USF2 is limited. The data of the current study show that USF2 function is regulated by phosphorylation and identified GSK3β as an(More)
Arsenite (As(III)) is widely distributed in nature and can be found in water, food, and air. There is significant evidence that exposure to As(III) is associated with human cancers originated from liver, lung, skin, bladder, kidney, and prostate. Hypoxia plays a role in tumor growth and aggressiveness; adaptation to it is, at least to a large extent,(More)
