Screening of differentially expressed genes in mouse hepatocarcinoma ascites cell line with high potential of lymphatic metastasis / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To screen genes differentially expressed in mouse hepatocarcinoma ascites cell line with high potential of lymphatic metastasis.</p><p><b>METHODS</b>A subtracted cDNA library of mouse hepatocarcinoma cell line with high potential of lymphatic metastasis Hca-F and its synogenetic cell line Hca-P with low metastatic potential was constructed by suppression subtractive hybridization (SSH) method. The screened clones of the subtracted library were sequenced and GenBank homology search was performed.</p><p><b>RESULTS</b>Ten differentially expressed cDNA fragments of Hca-F with high potential of lymphatic spreading were obtained, two of which were newly identified ones.</p><p><b>CONCLUSION</b>SSH is a useful technique to detect genes of differential expression and an effective method to clone novel genes.</p>
