HLA-C and cancer: To further explore the potential function of CREB3L1 in regulating the tumor immune microenvironment in human cancers, we examined the associations between CREB3L1 expression and the expression of major histocompatibility complex (MHC) genes (Figure 7A), lymphocyte (Figure 7B), immunoinhibitor genes (Figure 7C), immunostimulator genes (Figure 7D), chemokine (Figure 7E) and chemokine receptors (Figure 7F) by gene co-expression analyses in TISIDB.
