SOAT1 Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Acely-CoA:cholestorl acyltransferase (ACAT) is an integral membrane enzyme that belongs to type-B carboxylesterase/lipase family. ACAT catalyzes the formation of cholesteryl esters from cholesterol and long-chain fatty-acyl-coenzyme A (1). ACAT also function as a regulator of intracellular cholesterol homeostasis at single cell level. Two isoform of ACAT exists, ACAT1 and ACAT2, are expressed in liver and intestine. However, ACAT1 is only found in macrophages and SMCs (2). The accumulation of cholesteryl esters produced by ACAT in macrophages can lead to foam cell formation, an indication of early stage atherosclerosis. ACAT activity has been linked to Alzehimer's Diease, condition caused by excess amount of amyloid beta-peptide (Abeta). Atherogenic lipoproteins activate ACAT activity, where active ACAT can modulate the level of Abeta (3).
