The gene expression level of mucin 4, a mucosal extracellular matrix protein reported to be upregulated by IL-6 in gastric cancer cell lines [20], was significantly upregulated by HM (1.40-fold, p = 0.025) and LPS (1.52-fold, p = 0.031), compared with the basal mucin 4 gene expression level monitored in the untreated cells, the Control (Fig. 4B). This evidence concerns the gene MUC4 and gastric cancer.
