There were also statistically significant positive correlations between the tumor diameter and the normalized expression levels of KRT7, GATA3 and FOXM1; between the tumor grade and the normalized expression levels of KRT7, VTCN1, CD44, GATA3, RORC, NECTIN2, LRG1, CD276 and FOXM1; and between the PR and the normalized expression levels of ALOX15B and NECTIN2. The gene discussed is KRT7; the disease is neoplasm.
