ABSTRACT
<p><b>OBJECTIVE</b>To observe the expression of DNA damage checkpoint mediator 1 (MDC1) and p53-binding protein 1 (53BP1) at both mRNA and protein levels and their significance in different human esophageal cancer cell lines.</p><p><b>METHODS</b>In 3 human esophageal carcinoma cell lines, TE-1, TE-13 and Eca109 cells, the expressions of MDC1 and 53BP1 mRNA were detected with RT-PCR, and MDC1 and 53BP1 protein expressions were measured with immunohistochemistry, indirect immunofluorescence and Western blotting, respectively.</p><p><b>RESULTS AND CONCLUSIONS</b>MDC1 and 53BP1 expressions were observed for the first time in human esophageal carcinoma cell lines TE-1,TE-13 and Eca109 cells, at both the mRNA and protein levels. The expressions of MDC1 and 53BP1 proteins may be implicated in the radiosensitivity of human esophageal carcinoma.</p>
