Hypothesis
Furin-like proconvertases are central regulators of inhibin α- and β-subunit processing within the ovary.
Conclusion
PCSK5 plays a significant role in the processing of ovarian inhibin subunits during folliculogenesis.
Supporting Evidence
- PCSK5 mRNA was significantly elevated during the transition from two-layer secondary to pre-antral follicles.
- Inhibition of proconvertase activity impeded inhibin subunit maturation in granulosa cells.
- Activin A enhanced PCSK5 expression in cultured follicles.
Takeaway
This study shows that a specific enzyme, PCSK5, helps in the development of important hormones in the ovaries, which are necessary for fertility.
Methodology
Real-time quantitative RT-PCR was used to analyze the expression of proconvertases in developing mouse ovaries.
Participant Demographics
Prepubertal female F1 hybrids (C57BL/6XCBA) mice were used.
