Cholesterol depletion enhanced free cholesterol accumulation on LD surface in adipocytes.
A and B, cholesterol depletion by HPCD in FBS medium (A) and HPCD in LPDS medium (B) promoted free cholesterol accumulation on the LD surface in mature adipocytes stably overexpressing ACAT1/2. Bars, 10 μm. Inset, bars, 1 μm. C, quantification of free cholesterol-LD colocalization in A and B. One-way analysis of variance was used (minimum to maximum, line at median; n = 10 cells). **, p < 0.01; ****, p < 0.0001.
