This month’s image comes from a recent press release from the lab of Ron Evans. The paper published in 细胞代谢 explains how a gene pathway called PPARD is triggered by aerobic exercise, activating genes involved in burning fat for energy but suppressing genes involved in burning sugar (to save glucose for use by the brain). The team found continuing evidence that PPARD can be activated by a drug, and showed that sedentary mice who took the pill were able to run 70% longer than control mice. The new study may lead to “exercise-in-a-pill” for people who cannot exercise aerobically due to health or mobility issues.
