癌細(xì)胞利用腹部干細(xì)胞來(lái)推動(dòng)增長(zhǎng)和轉(zhuǎn)移。研究表明,一種新的方式即通過(guò)破壞使他們能夠茁壯成長(zhǎng)的代謝過(guò)程,來(lái)靶向治療惡性卵巢癌。在新的研究中,合著者Bahar Salimian進(jìn)行了一系列實(shí)驗(yàn)來(lái)研究O-ASCs和卵巢癌細(xì)胞之間復(fù)雜的相互作用。O-ASCs是一類在網(wǎng)膜中發(fā)現(xiàn)的成體干細(xì)胞,網(wǎng)膜是小腹中的組織,其是卵巢癌zui常見的轉(zhuǎn)移部位之一。
當(dāng)我們?cè)趯?shí)驗(yàn)室共同培養(yǎng)兩種細(xì)胞類型(癌細(xì)胞和O-ASCs),我們發(fā)現(xiàn),癌細(xì)胞會(huì)利用干細(xì)胞分泌的精氨酸,并且癌細(xì)胞通過(guò)燃燒精氨酸,來(lái)釋放瓜氨酸,這又造成了干細(xì)胞產(chǎn)生更多精氨酸。
我們的研究結(jié)果表明,O-ASCs通過(guò)增加一氧化氮水平,上調(diào)糖酵解和降低腫瘤細(xì)胞的氧化應(yīng),Nagrath說(shuō):值得注意的是,我們還發(fā)現(xiàn)在癌細(xì)胞中O-ASC介導(dǎo)的耐藥可以通過(guò)改變癌癥所依賴的一氧化氮平衡來(lái)逆轉(zhuǎn)。Nagrath說(shuō)一種破壞干細(xì)胞和腫瘤細(xì)胞之間信號(hào)的雞尾酒療法,可能破壞卵巢癌依靠的以推動(dòng)其轉(zhuǎn)移性增長(zhǎng)的代謝平衡。
Cancer cells use abdomen stem cells to promote growth and metastasis. Recent research shows that a new way to target malignant ovarian cancer is by disrupting the metabolic processes that allow them to thrive. In a new study, co-author Bahar Salimian conducted a series of experiments to investigate the complex interactions between O-ASCs and ovarian cancer cells. O-ASCs are a group of adult stem cells found in the omentum, the tissue in the lower abdomen that is one of the most common metastatic sites of ovarian cancer.
When we co-cultured two cell types (cancer cells and O-ASCs) in the laboratory, we found that cancer cells utilize arginine secreted by stem cells and that cancer cells release citrulline by burning arginine, which In turn, stem cells produce more arginine.
Our results show that O-ASCs up-regulate glycolysis and reduce the oxidation of tumor cells by increasing nitric oxide levels, Nagrath said: "It is noteworthy that we have also found that O-ASC-mediated resistance in cancer cells Drugs can be reversed by altering the balance of nitric oxide on which the cancer depends. Nagrath said a cocktail of drugs that disrupt the signal between stem cells and tumor cells could destroy the metabolic balance that ovarian cancer depends on to promote its metastatic growth.
