a) Representative Western blot analysis of FSP27 in WT 3T3-L1 adipocytes and FSP27 over-expressing adipocytes treated with 500ng/mL bGH for two hours.
b) Lipolysis as measured by glycerol release from WT 3T3-L1 adipocytes and FSP27 over-expressing adipocytes treated with 250ng/mL bGH for two hours. Data are shown as mean ± SEM of 3 independent experiments. Asterisks indicate a significant differences * p<0.05, ** p<0.01, *** p<0.001
c) Immunofluorescence of Nile Red Stained WT and FSP27 over-expressing 3T3-L1 adipocytes treated with vehicle or 500ng/mL bGH for 24 hours.
d) Representative Western blot analysis of pAKT S473 and total AKT in WT 3T3-L1 adipocytes and FSP27 over-expressing adipocytes treated with 250ng/mL bGH for two hours and 10nM insulin for 15 minutes.
d) Proposed mechanism of GH-induced lipolysis.
