We performed lectin histochemistry with phytohemag glutinin-L (L-PHA) and Sambucus nigra lectin (SNA); and immunohistochemistry for Gal-1, Gal-3, carbonic anhydrase IX, hypoxia-inducible factor, estrogen receptor (ER), progesterone receptor and human epidermal growth factor receptor type-2 for 86 IDC samples.
EGFRR497K (Arg497Lys) and (CA)n polymorphisms were genotyped, and the difference of their allele and genotype frequencies distribution between DCM patients and controls were analyzed.
