Fig. 4. Effect of garlic extracts on cAMP content of 3T3-L1 preadipocytes. The highest concentration (100 μg/mL) of garlic extracts that did not cause cytotoxicity to 3T3-L1 preadipocytes were evaluated. VG: vinegar pickled garlic, PG: pickled garlic, RG: raw garlic, cAMP: cyclic adenosine monophosphate, MDI: 0.5 mM 3-isobutyl-1-methylxanthine, 1 μM dexamethasone, 10 μg/mL insulin. All values are means measured in three independent experiments. Values are mean±standard deviation. Means with the same letter superscripts in the bars do not differ significantly at the 5% level.
