U-18666A increases cholesterol uptake in Jurkat cells as measured by flow cytometry.
Jurkat cells were seeded at a density of 5x105 cells/mL and incubated overnight in serum-free RPMI with U-18666A or vehicle and 20 μg/mL NBD Cholesterol in a cell culture incubator at 37°C. The next day, cells were transferred to a v-bottom plate for washing and reading on a flow cytometer. Cholesterol uptake was evaluated in the live cell gate using FlowJo analysis software. U-18666A at both 2.5 μM (green) and 1.25 μM (blue) showed a significant (p<0.05, t-test) shift in mean fluorescence as compared to the vehicle control (black) and the untreated (red) cells.

Blocking intracellular cholesterol transport with U-18666A increases NBD cholesterol uptake
製品の詳細
Cholesterol Uptake Assay Kit (ab236212) provides a convenient tool for studying cellular cholesterol trafficking. The kit employs NBD Cholesterol, a fluorescently-tagged cholesterol, as a probe for the detection of cholesterol taken up by cultured cells. U-18666A, which increases cholesterol uptake by inhibiting trafficking of synthesized cholesterol, is included as a positive control. The kit provides enough NBD Cholesterol to test 250 samples in a 96-well format.

Biological function summary
Cholesterol uptake plays a significant role in maintaining cellular cholesterol homeostasis. The process involves NPC1L1 working as part of a larger macromolecular complex with other proteins like clathrin and adaptor protein 2 (AP2) which facilitate endocytosis of cholesterol into enterocytes. These interactions occur in the brush border of the intestinal lumen allowing for cholesterol to be transported and re-esterified into chylomicrons which then enter lymphatic circulation.
Pathways
Cholesterol uptake is a critical component of cholesterol metabolism and homeostasis. It is specifically involved in the reverse cholesterol transport pathway which manages the movement of cholesterol from peripheral tissues back to the liver. Within this pathway NPC1L1 interacts with other proteins such as apolipoprotein B48 (ApoB48) to facilitate the formation of chylomicrons that transport cholesterol. Another pathway influenced by cholesterol uptake is the bile acid synthesis pathway where excess cholesterol is converted to bile acids.
