Pleiotropic effects of CXC chemokines in gastric carcinoma: differences in CXCL8 and CXCL1 expression between diffuse and intestinal types of gastric carcinoma

SUMMARY CXC chemokines modulate host immunity, neovascularization, growth and invasive behaviour of tumours. Despite their relevance in tumour biology, chemokine expression in intestinal‐ and diffuse‐type gastric carcinoma, which exhibit a completely different growth pattern, has not been investigat...

description SUMMARY CXC chemokines modulate host immunity, neovascularization, growth and invasive behaviour of tumours. Despite their relevance in tumour biology, chemokine expression in intestinal‐ and diffuse‐type gastric carcinoma, which exhibit a completely different growth pattern, has not been investigated in detail. In this study, expression of the CXC chemokines CXCL8 [interleukin (IL)‐8], CXCL1 [growth‐related oncogene alpha (Groα)], CXCL9 [monokine induced by interferon (IFN)‐γ] and CXCL10 [IFN‐γ‐inducible protein‐10 (IP‐10)] and the corresponding chemokine receptors CXCR1–3 was investigated by immunohistochemistry in intestinal‐ and diffuse‐type gastric carcinoma. Tumour cells of all patients expressed CXCL8. CXCL8 expression was significantly stronger in tumour cells of diffuse‐ rather than intestinal‐type gastric carcinoma (P

Tumour cells of all patients expressed CXCL8. CXCL8 expression was significantly stronger in tumour cells of diffuse‐ rather than intestinal‐type gastric carcinoma (P &lt; 0·01) as determined by a semiquantitative score. CXCL1 was expressed almost exclusively by diffuse‐ but not intestinal‐type carcinoma cells. The corresponding chemokine receptors, CXCR1 and CXCR2, were found on carcinoma cells. Furthermore, CXCL8 expression correlated with number of tumour vessels (P &lt; 0·01), suggesting an angiogenetic function in gastric carcinoma not only in vitro but also in vivo. CXCL10 and CXCL9, attractants for T cells, were expressed by peritumorous macrophages in close proximity to IFN‐γ‐producing CXCR3‐positive T cells in both tumour types. These chemokines may attract gastric carcinoma‐infiltrating T cells via an IFN‐γ‐mediated pathway and enhance host immunity against the tumour. In gastric carcinoma a complex interplay between CXC‐chemokine signals derived from both tumour cells and tumour‐infiltrating immune cells may exhibit pleiotropic effects in tumour biology that go far beyond their originally described functions as leucocyte chemoattractants. Because CXCL8 and CXCL1, which are known to increase growth and invasive behaviour of malignant tumours, are significantly stronger expressed in diffuse‐ than intestinal‐type gastric carcinoma, one may speculate that these chemokines influence the different growth pattern of gastric carcinoma types.</description><identifier>ISSN: 0009-9104</identifier><identifier>EISSN: 1365-2249</identifier><identifier>DOI: 10.1111/j.1365-2249.2003.02305.x</identifier><identifier>PMID: 14632759</identifier><identifier>CODEN: CEXIAL</identifier><language>eng</language><publisher>Oxford, UK: Blackwell Publishing Ltd</publisher><subject>Antigens, CD - analysis ; Antigens, CD34 - analysis ; Antigens, Differentiation, Myelomonocytic - analysis ; Biological and medical sciences ; Carcinoma - blood supply ; Carcinoma - immunology ; Carcinoma - pathology ; CD3 Complex - analysis ; Chemokine CXCL1 ; Chemokine CXCL10 ; Chemokine CXCL9 ; chemokine receptors ; Chemokines, CXC - analysis ; Clinical Studies ; CXC chemokines ; gastric carcinoma ; Gastroenterology.
