What the researchers found
Gelatin hydrolysate (CH) from Pacific cod skin significantly inhibited the UV-induced upregulation and activity of MMP-1, MMP-3, and MMP-9 in mouse skin, preserved collagen content, and suppressed MAPK pathway activation including ERK and p38 phosphorylation, thereby protecting against photoaging.
Why it matters
Understanding how natural peptides inhibit enzymes that degrade collagen can lead to new treatments or skincare products that prevent or reduce skin aging caused by UV exposure. This could improve skin health and appearance.
How the study worked
The study used a mouse skin photoaging model exposed to UV irradiation. Quantitative real-time PCR and ELISA assays measured MMP expression and activity, while molecular analyses assessed MAPK signaling pathway components after treatment with gelatin hydrolysate (CH) derived from Pacific cod skin.
What this study cannot tell us
The study was conducted in a mouse model, so results may not fully translate to humans. The exact dosage and delivery method for optimal effects in humans remain to be established.
