The data shows that the expression of GSN (https://www.proteinatlas.org/ENSG00000148180-GSN/pathology/stomach+cancer#ihc) is down-regulated in gastric cancer tissues, while TFRC (https://www.proteinatlas.org/ENSG00000072274-TFRC/pathology/stomach+cancer#ihc) and PIGR (https://www.proteinatlas.org/ENSG00000162896-PIGR/pathology/stomach+cancer#ihc) are upregulated in gastric cancer tissues. The gene discussed is TFRC; the disease is cancer.
