中文摘要:

PDCD5 是新奇 apoptosis 相关的基因。PDCD5 的 Overexpression 在各种各样的肿瘤房间便于 apoptosis。这里,我们在 hematologic 恶意的 chemosensitivities 调查了 recombinant 人 PDCD5 (rhPDCD5 ) 蛋白质的角色。rhPDCD5 增加了在里面 daunorubicin (DNR ) 的 vitro cytotoxicity, adriamycin (ADM ) 并且作为 2 在三个 hematologic 肿瘤房间的 O 3 排队。在研究显示出的 vivo,显著地与 rhPDCD5 相结合的那 DNR 独自与 DNR 相比压制了 U937 异种皮移植裸体人老鼠的肿瘤生长。在结论,与化学疗法的药相结合的 rhPDCD5 独自比化疗有更大的功效,并且 rhPDCD5 是很有希望的 chemosensitizer。

英文摘要:

PDCD5 is a novel apoptosis-related gene. Overexpression of PDCD5 facilitates apoptosis in various tumor cells. Here, we investigated the roles of recombinant human PDCD5 (rhPDCD5) protein in chemosensitivities of hematologic malignancies. The rhPDCD5 increased the in vitro cytotoxicity of daunorubicin (DNR), adriamycin (ADM) and As203 in three hematologic tumor cell lines. In vivo studies showed that DNR combined with rhPDCD5 significantly suppressed tumor growth of U937 xenograft nude mice compared with DNR alone. In conclusion, rhPDCD5 combined with the chemotherapeutic drug has greater efficacy than chemotherapy alone, and rhPDCD5 is a very promising chemosensitizer.
