Abstract

Gastric cancer is a type of cancer with increasing incidence and high mortality rates, but molecular biomarkers of diagnostic and therapeutic value are currently lacking. The aim of the present study was to examine the expression pattern of the interleukin 1 receptor‑like 1 (ST2) protein and assess its clinicopathological significance in gastric cancer. Western blot analysis of 12 gastric cancer specimens and paired adjacent tissues demonstrated that the protein levels of 2 isoforms of ST2, soluble secreted ST2 and the ST2 variant without the third immunoglobulin motif and splicing in the C‑terminal, were markedly decreased in cancer tissues compared with non‑cancerous tissues. Immunohistochemical analysis demonstrated that ST2 protein expression was markedly decreased in primary gastric cancer tissues (39.1%, 90/230) compared with adjacent non‑cancerous tissues (60.7%, 54/89) (P<0.05). Statistical analysis demonstrated that decreased ST2 expression was significantly associated with advanced tumor node metastasis stage (P<0.001) and tumor differentiation (P<0.001). These data suggest that ST2 protein may be a valuable biomarker of gastric cancer progression and pathogenesis.
