The fluorescent dye DiI‐labeled LDL has been widely used to measure the efficiency of LDLR‐dependent cholesterol uptake.[43, 44] To investigate the potential regulatory role of the miR‐19a/LDLR axis in tumoral cholesterol absorption, we first assessed the exogenous DiI‐LDL uptake capacity of glioma cells (Figure 6A). This evidence concerns the gene LDLR and glioma.
