Because Epstein-Barr virus (EBV)-associated gastric cancer (EBVaGC) is a unique subtype of GC and has features as the monoclonal proliferation of EBV-infected epithelial cells [28,29], we also detected EBV-encoded small RNA (EBER) via QDs-based fluorescence in situ hybridization (QDs-FISH) to investigate the influence of EBV infection on fibroblastic Cav-1 and LC3B expression. The gene discussed is MAP1LC3B; the disease is gastric cancer.
