The real world is messier
The loss of BH4 leads to the decoupling of nitric oxide synthase (NOSs) and superoxide formation
Mechanistically, high-glucose conditions induced robust upregulation of BMP4 and increased phosphorylation of its downstream effectors Smad1/5/9, driving tumorigenic signaling
Creatine, which research supports for muscle preservation during caloric restriction, is also missing
In addition, COX-2, which is encoded by prostaglandin-endoperoxide synthase (PTGS2), converts AA to multiple prostaglandins, including prostaglandin E2 (PGE2), which is also involved in inflammation
Many traditional small molecule drugs, such as glimepiride, metformin, and acarbose, help to control blood sugar levels
