FIGURE 5.

Sweet potato extract (SPE) suppressed nuclear factor kappa B (NF-κB) activation during liver steatosis, but inflammation was not caused in the high fat diet (HFD)-fed mice. (A) Representative pictures of the liver from every group of mice in H&E and Oil Red O staining. (B) Relative mRNA expression of NF-κB, IL-6, tumor necrosis factor α (TNF-α), peroxisome proliferator-activated receptor α (PPAR-α), and carnitine palmitoyl transferase 1 (CPT-1) in mouse livers. The black arrows indicate major hepatic macrovesicular steatosis. Values are means ± SEM, n = 5. *p < 0.05.
