A chemical called PD 098063 can turn down a protein (VCAM-1) that helps inflammation, but it doesn’t do this by blocking the usual inflammation switch (NF-kappa B)—it uses a different, unknown path instead.

Selective inhibition of tumor necrosis factor-induced vascular cell adhesion molecule-1 gene expression by a novel flavonoid. Lack of effect on transcription factor NF-kappa B.

Cross-Sectional Study

In Vitro

1996 Dec

The study found that PD 098063 stops VCAM-1 from being made without touching the NF-kappa B switch, which is exactly what the claim says — so it supports it.

Similar Assertions

A chemical called PD 098063 can stop a harmful inflammation signal (TNF) from making a sticky protein (VCAM-1) that attracts immune cells, but it doesn’t mess with the main alarm system (NF-κB) that usually turns on this protein—so it’s blocking the result without turning off the alarm.
