Gene function assembly analysis to screen key genes associated with deep vein thrombosis after trauma / 中华创伤骨科杂志

ABSTRACT

Objective To screen key genes related to deep vein thrombosis (TDVT) after trauma using gene function assembly analysis. Methods Thirty Sprague Dawley rats were randomized into control, thrombosis and non-thrombosis groups. Traumatic limb DVT models were established in rats through quantitative beating on the bilateral posterior limbs. The Genechip Rat genome 430 2. 0 genechips were applied to detect changes in genes expressions on difference phases of DVT. On the basis of the differential gene expressions in the thrombosis and non-thrombosis groups, the gene function assembly analysis was conducted to define the most significant and concentrated gene functions leading to the biological characters of DVT.Results B factor (bf), complement 4 binding protein α (C4bpα), plasminogen activator inhibitor 1 (serpinel), urokinase-type plasminogen activator receptor (plaur) were screened to be the key genes related to DVT, because they were found to be involved in the functions like complement activation, development,growth, morphogenesis, primary metabolism, cell motility, protein metabolism, localization of cell, locomotion and localization. The abundance values of the genes expressed were 1.6, -0. 2, 2. 1, 5. 1 in the thrombosis group, and -0. 5, - 1.4, 2. 7, 3. 3 in the non-thrombosis group. Conclusion Bf, C4bpα,serpinel, plaur may be the key genes that play a role in the process of DVT.
