Figure 2From: Eotaxin and FGF enhance signaling through an Extracellular signal-related kinase (ERK)-dependent pathway in the pathogenesis of Eosinophilic Esophagitisa There is a positive correlation between the fold expression of bFGF and ERK, suggesting that the upregulation of bFGF may also influence the upregulation of ERK. Figure 2b: There is a positive correlation between the fold expression of ERK and eotaxin-3.Back to article page
