Fig. 4From: Characterization of the expression and immunological impact of the transcriptional activator CREB in renal cell carcinomaCorrelation of HLA-G, HLA-E and CREB expression with grading of ccRCC. In ccRCC, staining intensity distribution among tumor grade categories varied for cytoplasmic HLA-G (B) and was inversely correlated for CREB (D), while there were no statistically significant differences for membranous HLA-G (A) or HLA-E (C)Back to article page
