此次研究中，研究人員通過導(dǎo)入這個基因的拷貝，實現(xiàn)了該受體的過量表達。而實際生活中，并不能將這一做法應(yīng)用到人身上，因而，研究人員將進一步開發(fā)靶向這一基因的藥物。
一項來自美國俄亥俄州立大學(xué)綜合癌癥中心的證據(jù)顯示，經(jīng)基因修飾的免疫細(xì)胞或?qū)Χ喟l(fā)性骨髓瘤的治療有效果，且這些細(xì)胞可在實驗室中培養(yǎng)增殖。該研究成果5月28日刊載在Clinical Cancer Research雜志。
研究人員對人類免疫細(xì)胞(來自患者的細(xì)胞系和骨髓瘤細(xì)胞)——T淋巴細(xì)胞進行修飾，靶向存在于大多數(shù)(占比95%以上)的骨髓瘤細(xì)胞中的CS1分子，以期殺死細(xì)胞。研究人員在實驗室中培養(yǎng)增殖這些修飾細(xì)胞，然后將其注入動物模型中，殺死人骨髓瘤細(xì)胞。
與對照組t細(xì)胞相比，修飾T細(xì)胞可以更好地識別過表達CS1的多發(fā)性骨髓瘤細(xì)胞，并激活。注射修飾T細(xì)胞的所有小鼠在接受治療后存活了44天，而在另外兩個對照組中，這一數(shù)據(jù)只有29%和17%。
這種療法的一個重要的優(yōu)勢是，這些治療T細(xì)胞在體內(nèi)有復(fù)制潛能，所以或許可以抑制腫瘤生長，長時間內(nèi)避免復(fù)發(fā)。
墨爾本的研究人員證明，A型白血病能成功地‘逆轉(zhuǎn)’通過誘騙癌癥細(xì)胞回到正常發(fā)育狀態(tài)。這一發(fā)現(xiàn)使用B-前體急性淋巴細(xì)胞白血病(B-ALL)模型，是一種zui常見的影響兒童的癌癥。研究人員揭示關(guān)閉一個稱為Pax5的基因在B-ALL模型中能夠誘發(fā)癌癥，而恢復(fù)它的功能能夠‘治愈’這種疾病。研究發(fā)表在《Genes & Development》期刊上。
研究者之一的劉女士說團隊利用一種發(fā)展的‘基因開關(guān)’技術(shù)去抑制然后再活化Pax5在白血病模型中。

In this study, researchers introduced an overexpression of this gene by introducing a copy of this gene. And in real life, this practice can not be applied to people, so the researchers will further develop drugs that target this gene.
Evidence from the Ohio State University Comprehensive Cancer Center shows that genetically modified immune cells or treatments for multiple myeloma can be effective and that these cells can be cultured and proliferated in the laboratory. The research was published May 28 in Clinical Cancer Research.
Researchers have modified human immune cells (cell lines from patients and myeloma cells), T-lymphocytes, to target CS1 molecules present in the majority (over 95%) of myeloma cells in order to kill cell. The researchers cultured and cultured these modified cells in a laboratory and injected them into animal models to kill human myeloma cells.
Modification of T cells allows better identification and activation of CS1-overexpressing multiple myeloma cells as compared to control t-cells. All mice injected with modified T cells survived for 44 days after treatment, compared with only 29% and 17% of the other two controls.
An important advantage of this therapies is that these therapeutic T cells have the potential to replicate in the body and so may be able to inhibit tumor growth and avoid relapse for long periods of time.
Researchers in Melbourne have demonstrated that type A leukemia can successfully 'reverse' by inducing cancer cells to return to their normal developmental state. This finding, using the B-ALL acute lymphoblastic leukemia (B-ALL) model, is one of the most common cancers in children. Researchers have revealed that the closure of a gene called Pax5 is capable of inducing cancer in the B-ALL model, and restoring its function to 'cure' the disease. Research published in "Genes & Development" journal.
Ms. Liu, one of the researchers, said the team took advantage of a newly developed 'gene switch' technique to repress and then reactivate Pax5 in leukemia models.
