CD79A and gallbladder neoplasm: Given the glandular gallbladder tumor as the most common GC in the clinic, we compared the glandular epithelial between normal and tumor tissues and found that extracellular matrix (ECM)–receptor interaction and focal adhesion processes were enriched from the upregulated genes in tumors, whereas antigen processing and presentation, intestinal immune network for IgA production, and complement and coagulation cascades were enriched from the downregulated genes in tumors (Figure S2I), suggesting the low immunogenicity and responses in GC.
