Fig 2 shows staining of SSTR1 in myocardial samples. While there was no evident positive staining of SSTR1 in control tissue, ICM tissues showed clear positive staining of SSTR1, with variability among samples (see images in last two columns). Although the signal of SSTR1 was present in all ICM specimens tested, the intensity of SSTR1 staining was comparable with the positive control neuroendocrine tumor in some specimens and stronger than the positive control in others. This is consistent with the tendency for SSTR1 gene expression. This evidence concerns the gene SSTR1 and neuroendocrine neoplasm.
