Abstract

The present study examined the kinetics of glutathione (GSH) concentration during maturation and after fertilization in pig oocytes and its relevance to the ability of pig oocytes to form a male pronucleus after in vitro fertilization. The GSH concentration was significantly higher in pig oocytes matured in Waymouth medium than in pig oocytes matured in either modified (m) TCM-199 or mTLP media. The addition of 0.04-0.57 mM cysteine (CySH) to mTLP significantly increased both the GSH concentrations in oocytes matured in vitro and the rate of male pronucleus formation as compared to those in oocytes cultured in mTLP alone. When pig oocytes were cultured 12, 24, or 36 h in mTLP plus 0.14 mM CySH, their GSH concentrations were significantly higher than in uncultured oocytes. After fertilization, the GSH concentration in pig oocytes declined significantly. GSH concentrations in oocytes matured in vivo did not differ from those in oocytes matured in mTLP plus 0.14 or 0.57 mM CySH. The results indicate that 1) the composition of maturation medium affects the GSH concentration in pig oocytes; 2) the addition of CySH to maturation medium permits GSH synthesis by the pig oocytes; 3) GSH levels in pig oocytes change during maturation and after fertilization; and 4) GSH synthesis during oocyte maturation is an important factor for promoting their ability to form a male pronucleus after fertilization.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
