Abstract:
OBJECTIVETo screen the genes related to the occurrence and development of varicosis of the great saphenous vein in the patients with primary deep vein valve insufficiency.
METHODSUsing mRNA fluorescent differential display reverse transcriptive polymerase chain reaction (FDD-RTPCR), different genes expressed in the varicose great saphenous veins in patients with primary deep vein valve insufficiency and corresponding normal human tissues were compared. Differentially expressed cDNA fragments confirmed by Northern blot were compared and then cloned into the pGEM-Teasy vector. Positive clones were selected and sequenced. All the sequences were put into GenBank and analyzed by BLASTN software to search for their genetic origins.
RESULTSAltogether 37 different cDNA fragments were obtained and 30 of which were confirmed by Northern blot. Analysis of the sequences by BLASTN software showed that C(610) fragment (NO. 18 cDNA clone) shared 96% homology with the mRNA sequence of the human Mckusick-Kaufman syndrome gene (MKKS gene).
CONCLUSIONC(610) fragment is highly homologous with the mRNA sequence of the human MKKS gene and is closely related to the development of varicosis of the great saphenous vein in patients with primary deep vein valve insufficiency.
