CPT1A and breast cancer: To test this idea, we used BODIPY 493/503 staining to monitor changes in intracellular lipid levels of BC cells with miR-328-3p overexpression and found that miR-328-3p overexpression significantly enhanced intracellular lipid droplet levels, but this was reversed by CPT1A overexpression (Fig. 5A, B, Supplementary Data 4A, B).
