Oviductal fluid protein patterns in the rhesus monkey (Macaca mulatta) during the menstrual cycle.
Oviducts were obtained from monkeys on Days 8, 14, 19 and 25 of the menstrual cycle and changes in the pattern of luminal fluid proteins were examined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Densitometric analysis after periodic acid Schiff's reagent (PAS) and coomassie blue staining of the gels revealed 85 and 95 kDa proteins only up to Day 14 whereas a 130 kDa glycoprotein persisted up to Day 19 and reached a nadir at mid-menstrual cycle (Day 14). The absence of the 130 kDa glycoprotein in the serum and its presence in cytosolic preparations up to Day 19 suggest that it is of oviductal origin. The 130 kDa glycoprotein is of particular interest since it was present in the oviductal fluid during mid cycle, a period when the oviduct participates in gamete transport, fertilization and embryo development. The conclusion drawn from this study is that the protein profile of monkey oviductal fluid changes during the menstrual cycle.
