The Claim

Choline kinase alpha (CHKA) regulates endothelial dysfunction in diabetic retinopathy through the NAD+-SIRT1-Notch signaling axis, where CHKA silencing reduces SIRT1 expression and increases Notch pathway activation, and NAD+ restoration reverses these effects.

How it works
1 study reviewed
In plain English

In diabetic retinopathy, reducing choline kinase alpha (CHKA) decreases SIRT1 and increases Notch pathway activity, leading to endothelial dysfunction; restoring NAD+ reverses these changes.

See the scientific wording

Choline kinase alpha (CHKA) regulates endothelial dysfunction in diabetic retinopathy through the NAD+-SIRT1-Notch signaling axis, as evidenced by reduced SIRT1 and increased Notch pathway activation following CHKA silencing, which is reversed by NAD+ restoration.

Why this might work

In diabetic conditions, a specific type of blood vessel cell in the eye increases production of CHKA, which keeps levels of NAD+ high. NAD+ activates SIRT1, which removes acetyl groups from a protein called NICD, causing it to break down. Without enough CHKA, NAD+ drops, SIRT1 becomes inactive, NICD stays active, and this blocks the formation of new blood vessels, leading to damage in the retina. Giving NAD+ back fixes this chain and restores normal vessel function.

  1. Study: Metabolic Stress‐Induced Choline Kinase α (CHKA) Activation in Endothelial Subpopulation Contributes to Diabetes‐Associated Microvascular Dysfunction

    When scientists blocked CHKA in diabetic mice, their eye blood vessels got worse because a key energy molecule (NAD+) dropped, and a growth signal (Notch) went haywire. But when they gave the mice a substance that boosts NAD+, half the damage got better — proving CHKA controls blood vessel health through this chain.
