Esculetin attenuates NF-κB pathway in LLC cells. Western blot analysis shows decrease in protein levels of transcription factor NK-κB and unaltered levels of its inhibitor I-κB in LLC cells. Proteins expression in LLC cells with or without Esculetin treatment (24h) was measured by Western blot (A). The relative protein level was normalized with β-actin and the quantitative data were represented as bar graph (B). Data were expressed as mean±S.E.M. *P<.05.
