Abstract<br />

In China, classical KS mainly occurs in Uygur <strong>and</strong> Kazak ethic group in Xinjiang<br />

Autonomous Region. The occurrence <strong>and</strong> development <strong>of</strong> sarcoma is linked with the<br />

abnormality <strong>of</strong> genes. For comprehensive clarifying the pathogenesis <strong>of</strong> KS in Xinjiang,<br />

We screened the differentially expressed genes between KS’ tissues <strong>and</strong> normal skin<br />

tissues from an classical patient <strong>of</strong> Uygur by Suppression subtractive hybridization (SSH).<br />

We cloned <strong>and</strong> sequenced them <strong>and</strong> established differential expression cDNA library on<br />

the base <strong>of</strong> SSH.Then we enlarged the samples <strong>and</strong> selected 4 classic patients to do the<br />

further screening by human genome U133 plus 2.0 microarray (Affymetrix). According to<br />

the bioinformatics analysis,we got the congenerous differentially expressed genes<br />

nearly 80. The function <strong>of</strong> them are focused on signal transduction <strong>and</strong> correlated with<br />

apoptosis or tumor occurrence. These studies identified a large number <strong>of</strong> genes whose<br />

expression was altered in KS. we have verified some <strong>of</strong> these differentially expressed<br />

genes by Real-time PCR <strong>and</strong> Immunohistochemistry, it’s consistent with the SSH <strong>and</strong><br />

gene chip results.We have carried on some functional study on these genes,such as 14-<br />

3-3β, HO-1, Neuritin, EGFR, MMP14, LYN, et al. We detected the expression level <strong>of</strong> KS<br />

associated genes in BC-3 cells <strong>and</strong> Human umbilical vein endothelial cells to analyze if<br />

infection <strong>of</strong> HHV8 have effect on the expression <strong>of</strong> these genes .Most <strong>of</strong> these genes were<br />

related with the infection <strong>of</strong> HHV8 <strong>and</strong> participate in cell proliferation, apoptosis <strong>and</strong> this<br />

might show particular relation in the pathogenesis <strong>of</strong> KS.<br />
