FIG. 1.
The expression profiles and intracellular localization of DOC2b in 3T3-L1 adipocytes. A: The expressions of DOC2a and DOC2b in 3T3-L1 fibroblasts, 3T3-L1 adipocytes (days 3 and 9 of differentiation), rat epididymal fat, and mouse brain were analyzed by mRNA blot. B: Differentiated 3T3-L1 adipocytes were serum-starved for 3–4 h and then stimulated with 100 nmol/l of insulin for 20 min, fixed, and immunostained. The endogenous DOC2b and GLUT4 were visualized using anti-DOC2b and anti-GLUT4 antibodies and observed by confocal microscopy.
