COL1A2 and esophageal squamous cell carcinoma: Wang Z et al.251demonstrated that expression levels of COL1A2 (encoding α2 chain of collagen I) and related genes (COL1A1, COL3A1, ZNF469, and POSTN) were positively correlated with the infiltration levels of macrophages and dendritic cells, and the expression levels of ZNF469 was also positively correlated with the infiltration levels of CD4+ T cells in both EAC and ESCC.
