A Correction on
Sex differences in cardiac mitochondria in the New Zealand obese mouse

By John C, Grune J, Ott C, Nowotny K, Deubel S, Kühne A, Schubert C, Kintscher U, Regitz-Zagrosek V and Grune T (2018). Front. Endocrinol. 9:732. doi: 10.3389/fendo.2018.00732

There was a mistake in Figure 2D as published. Accidentally, the immunoblot band of Figure 2B (male, NZO) was inserted in Figure 2D (female, NZO). The corrected Figure appears below.

Figure 2
Western blot image comparing protein levels in male and female B6 and NZO samples. The proteins analyzed are Myh7 at 243 kDa and α-tubulin at 50 kDa.

Figure 2. Protein and mRNA expression differences of cardiac myosine heavy chain isoforms 6 and 7. Myh6 mRNA expression level (A), Myh6 protein expression (B), Myh7 mRNA expression (C) and Myh7 protein expression (D). mRNA was normalized to Rpl13a and as protein expression reference α-tubulin was used. Mean ± SD. Two-way ANOVA with Tukey's posthoc test, *p < 0.05, **p < 0.01; B6 male: n = 5–10, NZO male: n = 7–10, B6 female: n = 5–10, NZO female: n = 7–10.
