Abstract:
OBJEVTIVETo 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.
METHODSThe 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.
RESULTSThe 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.
CONCLUSIONLentiviral 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.
