Regulation of Lipid Droplet Size in Mammary Epithelial Cells by Remodeling of Membrane Lipid Composition—A Potential Mechanism
Fig 1
Specific free fatty acids (FFAs) influence amounts and ratio between polar and neutral lipids in mammary epithelial cells.
Mammary epithelial cells were treated with 100 μM FFA (capric, palmitic or oleic acid) or with FFA-free medium (control) for 24 h; lipids were then extracted and analyzed by HPLC-ELSD. (A) Total lipid amount. (B) Triglyceride amount. (C) Total phospholipid amount. (D) Triglyceride-to-phospholipid ratio. All data are presented as mean ± SEM. Different letters indicate significant differences between treatment groups (P < 0.05).
