Positive staining of the p-p65 and p52 proteins in the BCa group (56.2 and 63.0%, respectively) was higher than that in the corresponding healthy groups (6.7 and 6.7%, respectively), a result similar to the cystitis (83.3 and 93.3% for p-p65 and p52, respectively) and healthy group comparison. This evidence concerns the gene RELA and chronic cystitis.
