This study evaluated the effect of soybean expeller (SBE) dietary supplementation on plasma antioxidant status in beef heifers during a four-month natural breeding season. Thirty-two were assigned into two groups over consecutive years. One group grazed Rhodes grass without SBE season (LSBE; n = 16), while other received at 0.6% body weight (BW) (HSBE; 16). Plasma was analyzed for total phenolic compounds, flavonoids, antiradical activity, and overall capacity. Oxidative stress measured...
Summary Urokinase-type plasminogen activator (uPA) is a serine protease involved in extracellular matrix remodeling through plasmin generation. uPA usually binds to its receptor, uPAR, which anchored the plasma membrane glycosylphosphatidylinositol anchor. uPA/uPAR binding increases proteolytic activity neighborhood of cells containing uPAR and activates intracellular signaling pathways remodeling, cell migration proliferation. The aim this work was study expression uPA, inhibitor-1 (PAI-1)...
Summary The mammalian oviduct plays a pivotal role in the success of early reproductive events. urokinase plasminogen activator system (uPAS) is present bovine and involved extracellular matrix remodelling through plasmin generation. This can be regulated by several members vascular endothelial growth factors (VEGF) their receptors. In this study, VEGF-D effect on regulation uPAS was evaluated. First, RT-polymerase chain reaction (PCR) analyses were used to evidence expression its receptors...
Abstract This study deals with the effect of plasminogen/plasmin on in vitro maturation (IVM) bovine cumulus‐oocyte complexes (COCs). Exogenous plasminogen activator streptokinase (SK) added to IVM medium revealed similar values cumulus expansion and oocyte nuclear compared controls (standard medium). However, a decrease both determinations was observed COCs matured supplementation ɛ‐aminocaproic acid (ɛ‐ACA), specific plasmin inhibitor. After fertilization, no differences were either...
Abstract In the present work, we established and characterized a 3D functional polarized primary bovine oviduct epithelial cells (BOECs) culture on free‐floating type I collagen hydrogels (rafts) at an air‐liquid interface (ALI). Intercellular junctions, ultrastructural cellular morphology expression of OVGP1 closely recapitulated those in vivo epithelium lining. These morphological physiological cell features were maintained under standard DMEM/F12 with 10% foetal serum medium for least 28...
Abstract Study question How does the meiotic spindle tubulin PTMs of MII oocytes matured in vitro compare to that vivo? Summary answer cultured present detyrosinated microtubules, while vivo do not. What is known already A functional required for chromosomal segregation during meiosis, but role post-translational modifications (PTMs) dynamics remains poorly characterized. In contrast with GVs within cumulus oophorous, maturation denuded stage (GV-MII) associated abnormalities, chromosome...
