Gene expression of hepatic stearoyl-CoA desaturase1 (SCD1), sterol regulatory element-binding protein1c (SREBP1c), endocannabinoid receptors (CB1 and CB2), fatty acid amide hydrolase (FAAH), and protein content of liver SCD1 relative to β-actin in sedentary (Sed) and trained (TR) rats submitted to a fast/refeeding protocol. Animals were fed a standard (SD) diet during 7 wks and thereafter were starved for 24 h and fed with the SD diet for 24 h and starved for another 24 h and then fed with the SD or the high-fructose (HFr) diet 24 h prior to sacrifice at the end of the 8th week. Values are means ± SE with  rats/group except for SCD1 protein level ( = 4–6 rats/group). &: significantly different from corresponding values under the SD diet, , &&: .
