The Claim

Apigenin and kaempferol reduce the expression of IL-6, IL-8, IL-1β, and MMP-3 in bleomycin-induced senescent human BJ fibroblasts through suppression of NF-κB p65 activity and IκBζ expression.

How it works
1 study reviewed
In plain English

Apigenin and kaempferol decrease the production of inflammatory proteins IL-6, IL-8, IL-1β, and MMP-3 in aged human skin cells by inhibiting NF-κB p65 and IκBζ.

See the scientific wording

Apigenin and kaempferol, two naturally occurring flavonoids, significantly reduce the expression of multiple senescence-associated secretory phenotype (SASP) markers—including IL-6, IL-8, IL-1β, and MMP-3—in bleomycin-induced senescent human BJ fibroblasts, likely through suppression of NF-κB p65 activity and IκBζ expression, suggesting a potential molecular pathway for mitigating chronic inflammation linked to cellular aging.

Why this might work

Plant compounds called apigenin and kaempferol block a signaling chain that triggers inflammation in old cells. They stop a protein called IRAK1 from activating, which prevents another protein, IκBα, from breaking down. This keeps IκBα bound to NF-κB p65, trapping it outside the cell nucleus. Without NF-κB p65 in the nucleus, a second protein called IκBζ is not made. Since IκBζ is needed to turn on inflammatory genes, the production of IL-6, IL-8, IL-1β, and MMP-3 drops sharply.

  1. Study: Effects of flavonoids on senescence-associated secretory phenotype formation from bleomycin-induced senescence in BJ fibroblasts.

    This study found that two plant chemicals, apigenin and kaempferol, can calm down the inflammatory signals released by old human cells in a lab, by blocking a key molecular switch (NF-κB) and a related protein (IκBζ). The same effect was seen in aging rats, suggesting these compounds might help reduce age-related inflammation.
