While Eng’s anti-inflammatory effects have been documented in intervertebral disc degeneration (via NF-κB/MAPK suppression [18]) and Alzheimer’s disease (through Nrf2 activation [17]), our work provides the first evidence of its AMPK/SIRT1/PGC-1α axis activation in IBD. The gene discussed is PPARGC1A; the disease is early-onset autosomal dominant Alzheimer disease.
