此次研究中,研究人員通過(guò)導(dǎo)入這個(gè)基因的拷貝,實(shí)現(xiàn)了該受體的過(guò)量表達(dá)。而實(shí)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(jìn)一步開(kāi)發(fā)靶向這一基因的藥物。
一項(xiàng)來(lái)自美國(guó)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(shí)驗(yàn)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(duì)人類(lèi)免疫細(xì)胞(來(lái)自患者的細(xì)胞系和骨髓瘤細(xì)胞)——T淋巴細(xì)胞進(jìn)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(shí)驗(yàn)室中培養(yǎng)增殖這些修飾細(xì)胞,然后將其注入動(dòng)物模型中,殺死人骨髓瘤細(xì)胞。
與對(duì)照組t細(xì)胞相比,修飾T細(xì)胞可以更好地識(shí)別過(guò)表達(dá)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(gè)對(duì)照組中,這一數(shù)據(jù)只有29%和17%。
這種療法的一個(gè)重要的優(yōu)勢(shì)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(zhǎng),長(zhǎng)時(shí)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(guò)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(jiàn)的影響兒童的癌癥。研究人員揭示關(guān)閉一個(gè)稱(chēng)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(shuō)團(tuán)隊(duì)利用一種發(fā)展的‘基因開(kāi)關(guān)’技術(shù)去抑制然后再活化Pax5在白血病模型中。
“隨著其它基因變化一起,失活的Pax5驅(qū)動(dòng)正常血細(xì)胞變成白血病細(xì)胞,之前已經(jīng)報(bào)道過(guò),”劉女士說(shuō)。“然而我們*揭示重新復(fù)活Pax5能夠使細(xì)胞重新開(kāi)始其正常發(fā)育并丟失那些類(lèi)似癌癥的特性,有效地治療白血病。吸引我們的是只是回復(fù)Pax5就足夠使這些癌細(xì)胞恢復(fù)常態(tài)化,盡管其它基因是改變的。”
白血病中,未成熟白血細(xì)胞復(fù)制異常并在骨髓中累積,干擾正常血細(xì)胞的產(chǎn)生。
劉女士說(shuō)在兒童B-ALL中Pax5常常是一個(gè)‘消失’的基因。“Pax5對(duì)于一種白血細(xì)胞——b細(xì)胞正常發(fā)育*的,”她說(shuō)。“當(dāng)Pax5功能缺乏抵抗力時(shí),發(fā)育中的B細(xì)胞陷入一種不成熟狀態(tài)并且變成癌性的。我們證明恢復(fù)Pax5功能,即使是在已經(jīng)發(fā)生癌病的細(xì)胞中,移除這個(gè)‘阻塞’,使得細(xì)胞發(fā)育成正常白血細(xì)胞。”
Dickins博士說(shuō)這項(xiàng)研究揭示了Pax5的功能,是約100種已知‘抑制’人類(lèi)腫瘤的基因之一。“當(dāng)這些腫瘤抑制基因通過(guò)改變DNA而被失活時(shí),腫瘤開(kāi)始發(fā)育,”Dickins博士說(shuō)。

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.
"As other genetic changes, inactivated Pax5 drives normal blood cells to become leukemic cells, as previously reported," Ms. Liu said. "However, for the first time, we have shown that resuscitation of Pax5 allows cells to restart their normal development and lose those cancers-like properties that effectively treat leukemias, and it is enough to appeal to Pax5 that these cells are restored to normalization, although other genes are changed."
In leukemia, immature white blood cells replicate abnormally and accumulate in the bone marrow, interfering with the production of normal blood cells.
Ms. Liu said Pax5 is often a 'vanishing' gene in children with B-ALL. "Pax5 is essential for the normal development of a white blood cell-b cell," she said. "When Pax5 function lacks resistance, developing B cells plunge into an immature state and become cancerous.We show that restoring Pax5 function, even in cells where cancer has already occurred, removes this 'obstruction' , Making the cells develop into normal white blood cells. "
Dr. Dickins said the study revealed the function of Pax5 and is one of about 100 genes known to 'suppress' human tumors. "Tumors begin to develop when these tumor suppressor genes are inactivated by changing DNA," says Dr. Dickins.
