Figure Lengend Snippet: ( A ) β-hydroxybutyrate (BHB) tolerance test in untrained 28-week-old male sedentary mice. Graphs displays mean ± SEM, with n ≥ 9. * P < 0.05 ( P = 0.02525 at 45 min, P = 0.021921 at 60 min), ** P < 0.01 ( P = 0.002777 at 90 min) by multiple t test between genotypes at different time-points. ( B ) The indicated age-matched male mice were run for 55 min at 18 m/min, and BHB was measured immediately after running (0 h), and 1–3 h post-run. The pre-run BHB values are from the same mice a day before the experiment. Data are mean ± SD, n = 10, n.s. not significant; P > 0.05, ** P < 0.01 ( P = 0.00121 at 0 h), * P < 0.05 ( P = 0.0485 at 2-h post-exercise), *** P < 0.001 (0.000233088 at 3-h post-exercise) by multi p le t test between genotypes at different time-points.

Figure Lengend Snippet: ( A ) RT-qPCR showing relative expression of indicated transcripts normalized to Hprt transcript levels using total RNA from WT and MEF2Dα2 Eko mice livers. Data are mean ± SEM, n = 5, Student’s t test found no differences in genotypes. ( B ) Representative time-courses of isolated mitochondrial respiration for WT and MEF2Dα2 Eko mice transitioning from state 1 to state 4 respiration under AKG± AcAc. The respiratory rates are expressed as nmol/min/mg mitochondrial protein. The transitions from state 1 to state 4 respiration were monitored by first adding isolated mitochondria (0.05 mg/mL) to the respiration buffer at t = 0 min leading to state 1. At t = 2 min, substrates were added to energize the mitochondria, which led to state 2 respiration. This was followed by sequential additions of incremental ADP concentrations (100 and 200 µM). AKG: Alpha-ketoglutarate and AcAc: acetoacetate. ( C ) MEF2D ChIP data from Gönczi et al viewed on IGV viewer (version 2.19.4) for Igfn1, Bdh1, Oxct1, and Acat1 gene locus. The bi-directional arrowed line shows the region where we designed our primers for our analyses. .
