<p><b>OBJEVTIVE</b>To investigate the inhibitory effect of lentiviral vector-mediated short hairpin RNA targeting survivin (LV-survivin shRNA) on the growth of human endometrium xenograft in the abdominal cavity of nude mice.</p><p><b>METHODS</b>The endometrium xenografts from 8 women with endometriosis were injected into the peritoneal cavities of 45 nude mice. The mice were then randomly assigned to receive intraperitoneal injection of LV-survivin shRNA, pGCL-NC-GFP (negative control) or PBS (blank control). Two weeks later, the number and morphometry of endometriotic lesions were quantified and the expression of survivin protein were detected by immunohistochemistry.</p><p><b>RESULTS</b>The formation of endometriotic lesions was significantly suppressed in mice receiving LV-survivin shRNA injection as compared with those in the two control groups (P/0.001). The mice in LV-survivin-shRNA group showed significantly down-regulated expression levels of survivin protein compared with those in the negative and blank control groups, presenting also necrosis in the endometriosis-like lesions in microscopic observation.</p><p><b>CONCLUSION</b>Lentiviral vector-mediated shRNA can effectively inhibit the expression of survivin in human endometrium xengrafts and suppress the formation and growth of endometriotic lesions in the abdominal cavities of nude mice.</p>
