Figure 6. Skeletal muscle in old Mtbp^+/- mice lack global metabolic marker increase. (A-H) Healthy Mtbp^+/+ (+/+; n=5; black) and Mtbp^+/- (+/-; n=8; gray) mice at 29 months were starved for 5 hours, sacrificed, and gastrocnemius muscle frozen with Wallenburg clamp. qRT-PCR for (A) glutaminase (Gls, p=0.5591; +/- n=7 due to RNA loss), (B) hexokinase 2 (Hk2, p=0. 9792), (C) ornithine decarboxylase (Odc, p=0.5115), (D) carbamoyl-phosphate synthetase 2/aspartate transcarbamylase/dihydroorotase, (Cad, *p=0.0202), (E) nucleolin (Ncl, p=0.9116, +/- n=7 due to insufficient RNA), (F) peroxisome proliferation activated receptor gamma coactivator 1-alpha (Pgc1α, p=0.0736), (G) Pgc1-beta (Pgc1β, p=0.0710), and (H) sirtuin-1 (Sirt1, p=0.8417) was performed. Values are relative to β-actin levels. P values calculated using student’s t-tests and error bars are SEM.
