en Biological and Clinicopathological Significance of Cripto-1 Expression in the Progression of Human ESCC زیست شناسی سلولی Cell Biology مقالات اصلی Original Article <p style="text-align: justify;"><strong><em>Background:</em></strong> Human Cripto-1, a member of the EGF-CFC family, is involved in embryonic development, embryonic stem cell maintenance, and tumor progression. It also participates in multiple cell signaling pathways including Wnt, Notch, and TGF-&beta;. Remarkably, it is expressed in cancer stem cell (CSC) compartments, boosting tumor cell migration, invasion, and angiogenesis. Although Cripto-1 is overexpressed in a variety of human malignant tumors, its expression in esophageal squamous cell carcinoma (ESCC) remains unclear. Our aim in this study was to evaluate the possible oncogenic role of Cripto-1 in ESCC progression and elucidate its association with clinicopathological parameters in patients.</p> <p style="text-align: justify;"><strong><em>Methods: </em></strong>In this study, Cripto-1 expression in 50 ESCC tissue samples was analyzed and compared to corresponding margin-normal esophageal tissues using quantitative real-time PCR.</p> <p style="text-align: justify;"><strong><em>Results:</em></strong> Cripto-1 was overexpressed in nearly 40% of ESCC samples compared with normal tissue samples. Significant correlations were observed between Cripto-1 expression and tumor differentiation grade, progression stage, and location (<em>p</em> < 0.05).</p> <p style="text-align: justify;"><strong><em>Conclusions:</em></strong> Our results indicate that overexpression of Cripto-1 is involved in the development of ESCC. Further assessment will be necessary to determine the role of Cripto-1 cross talk in ESCC tumorigenesis.&nbsp;&nbsp;</p> <p style="text-align: justify;"></p> Cancer stem cell, Cripto-1, ESCC, Expressional analysis, Real-time PCR 83 90 http://rbmb.net/browse.php?a_code=A-10-1-70&slc_lang=en&sid=1 Reihaneh Alsadat Mahmoudian 10031947532846006205 10031947532846006205 No Division of Human Genetics, Immunology Research Center, Avicenna Research Institute, Mashhad University of Medical Sciences, Mashhad, Iran.
