Hypothesis
The alternate pathway contributes to androgen bioactivity in Hsd17b3 knockout mice.
Conclusion
Mice lacking key androgen production enzymes maintain testosterone and DHT production through compensatory mechanisms.
Supporting Evidence
- Mice with disrupted androgen production pathways showed increased LH and maintained fertility.
- Testicular expression of SRD5A2 increased in the absence of HSD17B3, suggesting compensatory mechanisms.
- Circulating levels of alternate pathway steroids were elevated in Hsd17b3 knockout mice.
Takeaway
Mice can still make important hormones even if they are missing some of the usual tools to do so, like special enzymes.
Methodology
The study involved creating knockout mice lacking HSD17B3 and SRD5A1 and analyzing their hormone levels and reproductive health.
Limitations
The study primarily focused on male mice, and the findings may not directly translate to humans.
Participant Demographics
Adult male mice were used in the study.
