Effect of various substances on C/EBPβ, PPARγ, and C/EBPα protein expressions in 3T3-L1 preadipocyte differentiation. (a) Target protein expressions were visualized using immunoblotting in the treatment of DOW-RMD ethanol extracts (DOW-RE), UPW-RMD ethanol extracts (UPW-RE), SW-RMD ethanol extracts (SW-RE), monascin (MS), and ankaflavin (AK); (b) Target protein expressions were visualized using immunoblotting in the treatment of UPW, DOW, and SW. (c) Quantification of protein expressions in the treatment of DOW-RE, UPW-RE, SW-RE, MS, and AK. (d) Quantification of protein expressions in the treatment of UPW, DOW, and SW. Mean values with different superscripts are significant difference (p < 0.05).
