General description

7-ketocholesterol is a major oxidation product of cholesterol.

Application

<ul>
<li><strong>Cytoprotective effects of linolenic acid on 7-ketocholesterol-induced damage:</strong> This study highlights how specific fatty acids can mitigate the toxic effects of 7-ketocholesterol in neural and vascular cells, emphasizing potential therapeutic applications for neurodegenerative and cardiovascular diseases (Yammine et al., 2024).</li>
</ul>

Biochem/physiol Actions

7-ketocholesterol is a strong inhibitor of cytochrome P450 7A1. It modulates cholesterol homeostasis, cytotoxicity and apoptosis. 7-ketocholesterol stimulates inflammation, growth inhibition and vascular endothelial growth factor. Cellular accumulation of 7-ketocholesterol enhances oxidative stress, endoplasmic reticulum stress and apoptosis in macrophages.
