Dexamethasone reduces acrosin activity of ram spermatozoa
Tsantarliotou, M. P.; Taitzoglou, I. A.; Goulas, P.; Kokolis, N. A. (2002)The aim of this study was to investigate the effect of dexamethasone on acrosin activity of spermatozoa in Chios rams during autumn (breeding season for sheep in Greece), in correlation with possible changes in blood ... -
Dietary administration of tannic acid lowers plasminogen activator activity in the liver of C3H hepatoma bearing male mice
Taitzoglou, I. A.; Tsantarliotou, M. P.; Nepka, C. H.; Zervos, I.; Maltezos, E.; Kouretas, D.; Kokolis, N. A. (2000)Background: This study was undertaken to investigate if low-dose dietary administration of tannic acid exerts its chemopreventative activity on hepatocarcinogenesis in male C3H mice through changes of plasminogen activator ... -
Effects of dietary vitamin A intake on acrosin- and plasminogen-activator activity of ram spermatozoa
Zervos, I. A.; Tsantarliotou, M. P.; Vatzias, G.; Goulas, P.; Kokolis, N. A.; Taitzoglou, I. A. (2005)Acrosin and plasminogen activators are proteolytic enzymes of ram spermatozoa that play an essential role in the induction of the acrosome reaction, as well as the binding of spermatozoa to the oocyte and their penetration ... -
Gossypol-induced inhibition of plasminogen activator activity in human and ovine acrosomal extract
Taitzoglou, I. A.; Tsantarliotou, M.; Kouretas, D.; Kokolis, N. A. (1999)The effect of gossypol-a polycyclic compound isolated from cotton seeds-on the plasminogen activator activity of man and ram acrosomal extracts was explored in vitro. The action of gossypol on the plasminogen activator ... -
Inhibition of human and ovine acrosomal enzymes by tannic acid in vitro
Taitzoglou, I. A.; Tsantarliotou, M.; Zervos, I.; Kouretas, D.; Kokolis, N. A. (2001)The effect of tannic acid, a common flavonoid, on the acrosin and plasminogen activator activity and plasmin activity of human and ram spermatozoa was evaluated. Acrosin and plasminogen activator activity were determined ... -
Plasminogen activator activity in the porcine oviduct during the oestrous cycle
Tsantarliotou, M. P.; Zervos, I. A.; Vatzias, G.; Billinis, C.; Taitzogiou, I. A.; Kokolis, N. A. (2005)The mammalian oviduct is a dynamic tissue, which lies under the influence of ovarian steroids and produces proteins that affect various stages of fertilization and post-fertilization events. In this study, expression of ...
