摘要
AIM: To screen genes differentially expressed in mouse hepatocarcinoma ascites cell line with high potential of lymphatic metastasis.METHODS: A subtracted cDNA library of mouse hepatocarcinoma cell line with high potential of lymphatic metastatic Hca-F and its synogenetic cell line Hca-P with a low metastatic potential was constructed by suppression subtracted hybridization(SSH) method. The screened clones of the subtracted library were sequenced and GeneBank homology search was performed.RESULTS: Fourteen differentially expressed cDNA fragments of Hca-F were obtained with two novel genes.CONCLUSION: SSH is a useful technique to detect differentially expressioned genes and an effective method to clone novel genes.
