The total expression of proteins from both de novo ceramide synthesis and salvage pathways, e.g., (A) ceramide synthase 2 (CerS2), (B) ceramide synthase 4 (CerS4), (C) ceramide synthase 5 (CerS5), and (D) ceramide synthase 6 (CerS6), in the subcutaneous (SAT) and visceral (VAT) adipose tissues of rats fed a standard diet (control) or high-fat diet (HFD) after CBD treatment. The total expression of the above proteins was standardized to the total protein expression, and the control group was set to 100%. The data are expressed as mean values ± SD, n = 6 in each group. a
p < 0.05: significant difference: control group vs. experimental group; b
p < 0.05: significant difference: HFD vs. HFD+CBD.
