此前研究人員已經(jīng)發(fā)現(xiàn)了 5-LO 在炎性疾病比如哮喘癥發(fā)病中的角色，研究者 Jessica Roos 教授表示，這項(xiàng)研究中我們發(fā)現(xiàn)，急性髓性白血病亞群中的白血病干細(xì)胞或許可以被5-LO抑制劑有效地選擇性攻擊，而且這種現(xiàn)象均可以在細(xì)胞培養(yǎng)基模型和白血病小鼠模型中觀察到。
研究者表示，這項(xiàng)研究為開(kāi)發(fā)新型的5-脂氧合酶抑制劑來(lái)抑制白血病的存貨，從而為抑制并治療急性髓性白血病提供了新的研究依據(jù)和線索。后期研究中研究人員還將通過(guò)深入研究來(lái)揭示5-脂氧合酶抑制劑在抑制白血病干細(xì)胞功能中的作用和機(jī)制。
科學(xué)家們?cè)缇椭溃?dāng)細(xì)胞反復(fù)分裂時(shí)，就會(huì)發(fā)生染色體缺陷。隨著時(shí)間的推移，這些缺陷就會(huì)導(dǎo)致癌癥的發(fā)作。
現(xiàn)在，來(lái)自英國(guó)卡迪夫大學(xué)的鄧肯·貝爾德教授和他的研究團(tuán)隊(duì)與來(lái)自明尼蘇達(dá)大學(xué)的埃里克A·亨德里克森合作已經(jīng)確定了，人類細(xì)胞為了生存所需的這些類型的缺陷的一個(gè)特定基因。
“我們發(fā)現(xiàn)，似乎是在進(jìn)化過(guò)程中，可以驅(qū)動(dòng)癌癥的關(guān)鍵基因，” 卡迪夫大學(xué)的癌癥與基因研究所的貝爾德教授說(shuō)。“這是該基因的新作用，使其成為潛在的治療靶點(diǎn)。”
隨著細(xì)胞的分裂，它們的端粒——保護(hù)染色體末端免受損壞的DNA“帽”——縮短，使殘余的染色體容易彼此粘在一起。
在正常細(xì)胞中，這種染色體的粘性是一個(gè)死亡的信號(hào)，該信號(hào)能夠觸發(fā)缺陷的細(xì)胞在清理過(guò)程中移動(dòng)，并幫助清理它們的過(guò)程。
然而，惡性細(xì)胞，在某種程度上能夠躲避這個(gè)清理過(guò)程。
發(fā)表于近期的《Cell Reports》雜志上的一項(xiàng)研究，確定一個(gè)允許衰老的細(xì)胞逃避死亡的重要組成部分。
使用*基因靶向技術(shù)使人類細(xì)胞中的特定基因失去活性，然后研究端粒融合的影響，研究人員發(fā)現(xiàn)，只有當(dāng)連接酶3基因被激活時(shí)而不是它的作用，細(xì)胞才能逃過(guò)一死，這似乎更喜歡推動(dòng)染色體內(nèi)而不是不同的染色體之間的融合。
“在許多人類癌癥中，已經(jīng)確定端粒發(fā)生功能障礙，正如我們先前的研究顯示，短端粒可以預(yù)測(cè)慢性淋巴細(xì)胞白血病患者的預(yù)后，可能也可用于很多其他類型的腫瘤，” 貝爾德教授說(shuō)。“因此，這一過(guò)程需要連接酶3的發(fā)現(xiàn)是極其重要的。”
有趣的是，這項(xiàng)研究成為可能，是因?yàn)椋谝淮螘?huì)議上卡迪夫大學(xué)的的貝爾德教授和明尼蘇達(dá)大學(xué)的埃里克·亨德里克森教授的邂逅。
兩人很快就發(fā)現(xiàn)，他們都期待連接酶3在癌癥中的作用，于是，他們決定合作。
“此次合作得到了回報(bào)，因?yàn)槲覀儼l(fā)現(xiàn)了別人沒(méi)有發(fā)現(xiàn)的東西，” 亨德里克森教授說(shuō)。
重要的是，進(jìn)一步的研究已經(jīng)在進(jìn)行中。特別是，細(xì)胞逃避死亡依賴于連接酶3，反過(guò)來(lái)，依賴另一個(gè)關(guān)鍵的DNA修復(fù)基因，p53基因的活性則可修復(fù)細(xì)胞。
“既然p53是人類腫瘤中zui常見(jiàn)的突變基因，現(xiàn)在我們理應(yīng)認(rèn)識(shí)到這兩個(gè)基因的相互作用，看看我們是否能夠利用這些信息來(lái)制定協(xié)同治療方式，” 亨德里克森教授補(bǔ)充說(shuō)。

Researchers have previously discovered the role of 5-LO in the pathogenesis of inflammatory diseases such as asthma. Researchers Professor Jessica Roos said that in this study, we found that leukemic stem cells in the acute myelogenous leukemia subgroup may be blocked by 5- LO inhibitors effectively selectively attack, and this phenomenon can be observed in both cell culture and leukemia mouse models.
The researchers said the study provides new research evidence and clues for the suppression and treatment of acute myeloid leukemia in order to develop new 5-lipoxygenase inhibitors to inhibit the stock of leukemia. In the latter part of the study, researchers will further study to reveal the role and mechanism of 5-lipoxygenase inhibitors in inhibiting leukemia stem cell function.
Scientists have long known that chromosomal defects occur when cells repeatedly divide. Over time, these shortcomings can lead to the onset of cancer.
Now that Professor Duncan Baird from Cardiff University in the UK and his research team have worked with Eric A. Hendrickson from the University of Minnesota, one of these types of defects that human cells need in order to survive Specific gene.
"We found it to be a key gene that can drive cancer in the evolutionary process," said Professor Baird, a professor of cancer and genetics at Cardiff University. "This is a new role for the gene, making it a potential therapeutic target."
As the cells divide, their omeres - protecting the chromosome ends from damaged DNA "caps" - shorten the residual chromosomes to stick together easily.
In normal cells, the stickiness of this chromosome is a signal of death that triggers defective cells to move during the cleaning process and help cleanse them.
However, malignant cells, to some extent, are able to evade this cleanup process.
A study published in the recent Cell Reports identified an important component that allows aging cells to escape death.
Using advanced gene targeting techniques to inactivate specific genes in human cells and then to study the effects of omere fusion, the researchers found that the cell can escape death only if it is activated rather than its effect Seems to prefer to promote the fusion between chromosomes rather than different chromosomes.
"In many human cancers, dysfunction of omeres has been identified and, as our previous study showed, short omeres predict the prognosis of patients with chronic lymphocytic leukemia and may also be used in many other types of tumors," said Professor Baird . "Therefore, the discovery that ligase 3 is required for this process is extremely important."
Interestingly, the study was made possible by encounters with Professor Baird at Cardiff University and Professor Eric Hendrickson at the University of Minnesota at an international conference.
They quickly discovered that they both looked for the role of ligase 3 in cancer, so they decided to work together.
"This cooperation paid off because we found something that others did not find," said Hendrickson.
Importantly, further research is already under way. In particular, cell death depends on Ligase 3, which, in turn, relies on another key DNA repair gene whose activity can repair cells.
"Since p53 is the most common mutation in human tumors, we should now recognize the interaction of these two genes and see if we can use that information to formulate a co-treatment approach," Professor Hendrickson added.
