Low levels of PGC-1α exacerbate inflammatory responses and oxidative stress by downregulating mitochondrial antioxidant genes and promoting NF-κB activation, creating a vicious cycle of metabolic dysfunction.
To reduce chronic inflammation and oxidative stress, prioritize activities that boost PGC-1α expression, such as regular exercise, cold exposure, and fasting. These natural stimuli upregulate PGC-1α, which in turn enhances mitochondrial antioxidant defenses and suppresses inflammatory pathways like NF-κB.
During inflammation, low levels of PGC-1α downregulate mitochondrial antioxidant gene expression, induce oxidative stress, and promote nuclear factor kappa B activation.
Why this rating
The paper is a comprehensive review citing numerous studies across multiple tissue types (liver, muscle, heart, brain) and disease models (obesity, diabetes, sepsis).

More from this paper
- PGC-1α acts as a direct repressor of NF-κB transcriptional activity, specifically blocking the expression of proinflammatory cytokines like IL-6 and TNF-α.Good
- Upregulation of PGC-1α enhances mitochondrial antioxidant defense by increasing the expression of genes such as MnSOD, catalase, and peroxiredoxin, thereby protecting cells from oxidative damage.Good
