The Claim

Supplementation with nicotinamide mononucleotide (NMN) partially restores NAD+ levels and rescues endothelial angiogenic functions impaired by CHKA silencing in vitro and in vivo, indicating that CHKA regulates angiogenesis through NAD+ metabolism.

How it works
1 study reviewed
In plain English

Nicotinamide mononucleotide supplementation restores NAD+ levels and reverses impaired blood vessel formation caused by reduced CHKA activity in laboratory cell cultures and animal models.

See the scientific wording

Supplementation with nicotinamide mononucleotide (NMN) partially restores NAD+ levels and rescues endothelial angiogenic functions impaired by CHKA silencing in vitro and in vivo, indicating that CHKA regulates angiogenesis through NAD+ metabolism.

Why this might work

When CHKA is active, it keeps NAD+ levels high in blood vessel cells. High NAD+ turns on SIRT1, which removes a chemical tag from a protein called Notch, preventing it from staying active. When Notch is inactive, blood vessel cells can grow new branches and repair damaged vessels. If CHKA is turned off, NAD+ drops, SIRT1 stops working, Notch stays active, and blood vessels lose their ability to grow. Giving NMN restores NAD+, reactivates SIRT1, turns off Notch, and brings back blood vessel growth.

    When scientists blocked a protein called CHKA, blood vessels couldn't grow properly—but giving a supplement called NMN fixed half of that problem. This shows CHKA helps blood vessels grow by controlling NAD+ levels.
