Fig. 3From: FNDC5/irisin ameliorates bone loss of type 1 diabetes by suppressing endoplasmic reticulum stress‑mediated ferroptosisFNDC5 was decreased in the bone tissues of diabetic mice. (A) Relative mRNA level of FNDC5 in the bone tissues. n = 6 per group. (B, C) Relative protein level of FNDC5 in the bone tissues. n = 6 per group. (D, E) Immunohistochemical staining of FNDC5 in the bone tissues. n = 3 per group. Scale bar: 100 μm. **P < 0.01, ***P < 0.001 versus the CON groupBack to article page
