HILPDA is abundant in adipose tissue and localizes to lipid droplets. (a)
HILPDA mRNA levels across various human (n = 1) and mouse
tissues (n = 4). From top to bottom: liver, heart, skeletal muscle, WAT, BAT,
kidney, small intestine, and colon. Expression levels in WAT were set at 100%.
(b) Immunoblot for HILPDA in various mouse tissues (n = 1). (c)
Hilpda mRNA in adipose tissue of C57BL/6 mice fed a low-fat
diet (LFD) or high-fat diet (HFD) for 20 weeks. (d) The 3T3-L1 preadipocytes
were transfected with HILPDA-mCherry plasmid, loaded with 400 μM oleic
acid and, 48 hours posttransfection, stained with BODIPY and analyzed by
confocal microscopy. (e) The 3T3-L1 preadipocytes were transfected with
HILPDA-Turquoise2 plasmid (HILPDA-mTurq2) and CIDEB-mCherry plasmid, loaded
with 400 μM oleic acid, and analyzed by confocal microscopy 48 hours
after transfection. Asterisks indicate significant differences according to
Student t test relative to (c) LFD;
**P < 0.01. gWAT, gonadal white
adipose tissue.
