In contrast to the conventional notion regarding tumour development as a cell autonomous process in which the major participants were the cancer cells, increasing evidence attributes important role in the stromal components, namely fibroblasts, and view the tumour as a heterogenous mixture of different cell types. These different types of cells, being cancer cells, fibroblasts, endothelial cells, and others, interact reciprocally and play an almost equally important role in the manifestation of certain aspects of the malignant phenotype. The elucidation of the mechanistic base of such interactions, besides the contribution to understand fundamental aspects of tumour cell biology, promises important applications in diagnosis, prognosis and therapy of the disease.

Growth hormone-releasing hormone (GHRH) stimulates the production and release of growth hormone in the pituitary and induces cell proliferation in a variety of peripheral tissues and tumors. These extrapituitary effects of GHRH are in many cases mediated by a splice variant of GHRH receptor designated SV1 that differs from the pituitary GHRH receptor in a small portion of its amino-terminal region. While SV1 has been detected in several primary tumors and many cancer cell lines its expression in normal tissues remains unclear. In this study we report the results of an immunohistochemical analysis for SV1 and GHRH expression in normal mouse tissues. For the detection of SV1 immunoreactivity we used a polyclonal antiserum against segments 1-25 of the SV1 receptor protein. Mouse heart, colon, lungs, small intestine, stomach and kidneys exhibited increased SV1 immunoreactivity. These tissues were also positive for GHRH expression, however, tissues such as the endometrium were positive only for GHRH and not for SV1 expression. On the contrary, testis were positive for SV1 and not for GHRH expression. These results indicate that SV1 may play a role in normal physiology. 相似文献
