From: Histone demethylase LSD1 regulates bone mass by controlling WNT7B and BMP2 signaling in osteoblasts

WNT7B related mTOR signaling and BMP2 related BMP signaling contribute to the increased bone mass in Lsd1prx1 mice. a Lsd1 fl/fl calvarial cells derived from P3 mice were infected with Egfp or Cre virus followed by culture in osteoblast differentiation medium for 7 days. WNT7B and pS6K1 levels were measured by western blot. Results are representative of two independent experiments. b–f Femurs from 6 weeks female mice (n = 4–6) were analyzed by μCT. b 3D reconstructions of the trabecular bone and midshaft cortical bone. Quantitative parameters of trabecular bone (c–e) and cortical bone (f) were analyzed. ANOVA followed by Tukey’s post hoc test was performed. **P < 0.01. Scale bar, 0.5 mm. g Lsd1 fl/fl calvarial cells derived from P3 mice were infected with Egfp or Cre virus followed by culture in osteoblast differentiation medium for 7 days. LSD1, p-SMAD1/5/8, and BMP2 levels were measured by western blot. Results are representative of two independent experiments. h–l Femurs from 9 weeks Lsd1prx1 and Lsd1fl/fl male mice (n = 4–6) after BMP inhibitor LDN-193185 injection for 4 weeks were analyzed by μCT. h 3D reconstructions of the trabecular bone and midshaft cortical bone. Quantitative parameters of trabecular bone (I–k) and cortical bone (l) were analyzed. ANOVA followed by Tukey’s post hoc test was performed. *P < 0.05. Scale bar in h: 0.5 mm.
