7-Ketocholesterol is a lipid of Sterol Lipids (ST) class. 7-ketocholesterol is associated with abnormalities such as Atherosclerosis, Age related macular degeneration, Drusen, Cardiovascular Diseases and Hypercholesterolemia. The involved functions are known as mRNA Expression, Choroidal Neovascularization, Biochemical Pathway, Inflammation and Regulation. 7-ketocholesterol often locates in Basal lamina of choroid, Mitochondria, Epithelium, Frozen Sections and Membrane. The associated genes with 7-Ketocholesterol are ABCA1 gene, SLC33A1 gene, GAPDH gene, P4HTM gene and TSPO gene. The related lipids are Ketocholesterols, cholesterol oxide, Sterols, oxidized lipid and 7-ketocholesterol. The related experimental models are Knock-out and Mouse Model.
To understand associated biological information of 7-Ketocholesterol, we collected biological information of abnormalities, associated pathways, cellular/molecular locations, biological functions, related genes/proteins, lipids and common seen animal/experimental models with organized paragraphs from literatures.
7-Ketocholesterol is suspected in Atherosclerosis, Keratoconjunctivitis Sicca, endothelial dysfunction, Senile Plaques, Hypercholesterolemia, Hypercholesterolemia, Familial and other diseases in descending order of the highest number of associated sentences.
