Therefore, abrogation of Bmi-1 expression could be a potential therapeutic strategy against human cancers.

研究表明Bmi-1基因有望成为肿瘤治疗的新的靶点，从肿瘤干细胞水平抑制肿瘤的发生和发展。

We further evaluated the synergistic cytotoxicity of TRAIL in combination with actinomycin D, cisplatin and paclitaxel in A549 cell lines in vitro and in vivo.

本实验选择了人肺腺癌A549细胞瘤株作为我们实验研究的对象，通过TRAIL对人肺腺癌A549细胞诱导凋亡研究，在A549的荷瘤裸鼠的动物模型上研究了其体内的抗肿瘤活性，并进一步研究了TRAIL与化疗药物放线菌素D(actinomycin D，Act D)、紫杉醇和顺铂(cisplatin，CDDP)的联合作用对人肺腺癌A549细胞的体外协同抗肿瘤活性，通过化疗药物协同增强TRAIL抗肿瘤活性作用机制的初步研究，为降低临床化疗药的用药量，减轻其对机体的不良反应提供一定的理论基础。

Amitosis and asymmetric division play an important role in PC12 cell pleomorphism. The asymmetric division possesses important significance in tumorigenesis and differentiation.

无丝分裂和不对称分裂是PC12细胞多形性形成的主要原因，肿瘤细胞无丝分裂及其不对称性对肿瘤发生及肿瘤细胞的分化具有重要意义。

The tests show that said antihuman VEGF ScFv is small in molecular weight, possesses strong power for penetrating tumor ittue, its immunogenicity is low, so that it possesses the tumor-resisting function.

最终获得ScFv的高效表达，经测定证实抗人VEGF ScFv分子量小、对肿瘤组织穿透力强，免疫原性低，能阻遏肿瘤血管生成的抗肿瘤作用。

If the antitumour efficacy of these epigenetic drugs is eentually demonstrated, they would not only be added to the current anticancer armamentarium, but they will surely be affordable to the ast majority of cancer patients liing in low and middle income countries, who find the newer anticancer agents prohibitiely expensie.

如果这些表观遗传药物抗肿瘤的作用最终得到证实，他们不仅仅增加了当前抗癌的物质，而且他们可以明确的可以使在发现新的抗肿瘤剂相当昂贵的国家收入在中下等的大量肿瘤患者负担的起。

A neoplastic process, such as inflammatory myofibroblastic tumor or a metastatic malignant tumor, can calcify.

肿瘤，如炎症性成肌纤维细胞肿瘤或者恶性转移性肿瘤，也可由钙化。

Statistical data of TF grading scores showed that its expression was not significantly related to the size and location of glioma, sex, and age of patients, but closely related to the glioma gradings and microvessel quantity of the tumor.VEGF was found in gliomas of all gradings and its expression was significantly enhanced with the increase of glioma gradings.

TF分级计数统计结果显示其表达与肿瘤的大小、部位及患者性别、发病年龄等临床因素无显著相关性，但与肿瘤的分级及肿瘤微血管数量密切相关。2、VEGF在各级胶质细胞瘤组织中均有表达，随着肿瘤组织学分级的增加，VEGF的表达明显增强。

Tumor immunologists are moving away from traditional transplantation tumor systems because they do not adequately model human malignancies.

目前肿瘤免疫学研究的趋势正逐渐远离传统的制备肿瘤模型的凡是，因为传统的肿瘤种植模型并不能充分地模拟人类肿瘤的发生。

Background During the tumor angiogenesis and haematogenous metastasis, there exist complicated interactions between tumor cell and vascular endothelial cell. They interact and make joint efforts to contribute to establish the tumor vascular network and induce tumor invasion and metastasis.

研究背景：在肿瘤的血管系统建立和血行转移中，肿瘤细胞与血管内皮细胞之间存在复杂的相互关系，他们相互作用以促使肿瘤内血管网的出现和肿瘤的侵袭转移。

Nowadays, n stem-like cells have been found, which exist in the tumors of some tissues, such as haematogenesis system, brain, lung, mammary gland and so on. We defined them as tumor stem cells for their similar characteristics to the normal stem cells, but they are a minor population of tumor cells and the origin of them may be tumor cells.

随着对干细胞的研究不断深入，使人们对肿瘤的发生机制重新进行了审视，并在造血系统、脑、肺、乳腺等部位肿瘤中发现极少量的具有与干细胞非常类似生物学特性的细胞，称之为肿瘤干细胞，它们很可能是肿瘤细胞的起源。

Do you know, i need you to come back

你知道吗，我需要你回来
