Progesterone receptor gene expression in preimplantation pig embryos.
OBJECTIVE It is not known whether progesterone, which plays a key role in establishing and maintaining pregnancy, acts directly on embryos or indirectly through the mother's reproductive tract. Since the physiological effects of progesterone are mediated by progesterone receptors (PR), the expression of PR during the preimplantation stages of pig embryos was determined. DESIGN AND METHODS Pre...
متن کاملGlucose metabolism during bovine preimplantation development: analysis of gene expression in single oocytes and embryos.
Glucose metabolism of the bovine embryo is low during the first cleavages and increases sharply after the major resumption of the genome (8-16 cells). The mRNA level for genes involved in glucose metabolism was tested by RT-PCR on individual oocytes and embryos at different stages of development. These genes were: glucose transport GLUT-1, hexokinase (HK), glucose-6-phosphatase-dehydrogenase (G...
متن کاملMetabolism of [C]glucose by postimplantation mouse embryos in vitro
Carbon dioxide and lactate production from [C]glucose were measured for postimplantation mouse embryos aged 6 to 9| days post coitum in static cultures with a defined medium. The rate of metabolism increased rapidly and paralleled the increase in protein content indicating a fairly uniform rate of metabolism throughout the period. At all stages studied more than 90 % of the glucose utilized was...
متن کاملThe metabolism of exogenous fatty acids by preimplantation mouse embryos developing in vitro By
The utilization of fatty acids from the culture medium has been examined in preimplantation mouse embryos developing in vitro. Incorporation of exogenous fatty acid into embryo lipids was examined by culturing 8-cell mouse embryos for 2 h in a medium containing 01 mM [9, 10-H]palmitic acid (900 mCi/ mmol). Lipids were extracted from the embryos, and the total lipid extract was fractionated into...
متن کاملMetabolism of [14C]glucose by postimplantation mouse embryos in vitro.
Carbon dioxide and lactate production from [14C]glucose were measured for post-implantation mouse embryos aged 6 to 9 1/2 days post coitum in static cultures with a defined medium. The rate of metabolism increased rapidly and paralleled the increase in protein content indicating a fairly uniform rate of metabolism throughout the period. At all stages studied more than 90% of the glucose utilize...
