ABSTRACT
<p><b>OBJECTIVE</b>To construct the yeast two-hybrid system, and screen the proteins which interact with FasL, and investigate the relationship of FasL and hepatic metastasis of colorectal carcinoma.</p><p><b>METHODS</b>We have cloned the FasL gene into the pGBKT7 vector as the bait, then screened the fetal liver cDNA library, and have got a series of specific proteins that interact with FasL protein. Using the bioinformatics, we analyzed the interacting proteins in the mechanism of hepatic metastasis of colorectal carcinoma.</p><p><b>RESULTS</b>We have screened several proteins that interaction with FasL protein, including metallothionein 1K, 1G, 2A, cathepsin B, fatty acid synthase, interferon alpha-inducible protein 27, phospholipid scramblase, Ser/Thr-like kinase, anchor attachment protein, fibulin-5.</p><p><b>CONCLUSIONS</b>We have successfully constructed the yeast two-hybrid system, and preliminary identified that the interaction between FasL, metallothionein, cathepsin and anchor attachment protein is radically related to the hepatic metastasis of colorectal carcinoma.</p>
