Abstract:
Background: Heparansulfate Interacting Protein (HIP) is a protein that belongs to a novel class of heparin and heparansulfate binding protein. It plays an important role in extracellular matrix structure and function, cell-cell and cell-extracellular matrix adhesion, growth and differentiation. HIP was shown to be expressed in normal epithelia and epithelial cell lines at both mRNA and protein levels. Especially, HIP was found to be up-regulated in some cancer cell lines and related to different status and metastasis.\r\n', u'Objectives: To determinate HIP transcript level of mRNA in breast cancer tissues in comparison with normal tissues; to compare HIP transcript level at different cancer stages and cancer cell types. \r\n', u'Subjects and method: Total RNA was isolated from 62 tissue samples (47 breast cancer and 15 normal tissues); cDNA synthesis by reverse transcript \u2013polymerase chain reaction (RT \u2013 PCR); determination of HIP transcript using semi-quantitative RT \u2013 PCR. \r\n', u'Results: HIP transcript was particularly up \u2013 regulated in breast cancer tissues compared to normal tissues, especially this up-regulated in cancer tissues at different stages of development and cancer cell types. \r\n', u'Conclusion: These results show that the HIP transcript level was different between breast cancer and normal tissues and its expression was related to different status and metastasis in human cancer cell lines. HIP may be used as a prognostic marker for breast cancer.\r\n', u'
