For ERBB4 in the proteoglycans in cancer pathway, whose expression increases in the transition from healthy to low serosa, we found a moderate correlation between its expression and myeloid dendritic cell in borderline tissue (r = −0.59, p = 7 × 10−4), neutrophil in borderline tissue (r = −0.56, p = 0.0017), and cancer-associated fibroblast in borderline tissue (r = 0.37, p = 0.0045). This evidence concerns the gene ERBB4 and cancer.
