2016年11月10日 訊 /生物谷BIOON/ --近日,在利物浦舉辦的英國國家癌症研究所癌症會議(NCRI)上,來自英國倫敦大學學院的研究人員發表了他們的最新研究成果,研究者們指出,他們在惡性前列腺癌細胞中發現了一種新型的標誌物,該標誌物或可被用來指導前列腺癌療法的開發。
研究者們如今已經對這種名為NAALADL2的分子進行了測定來觀察是否患者的前列腺癌會發生復發,而且這項最新研究還指出,NAALADL2分子或許還能夠幫助指導前列腺癌的治療。相比健康組織的細胞而言,研究者們在前列腺癌細胞上發現了多個NAALADL2分子,而且攜帶高水平該分子的前列腺癌患者術後癌症復發的風險要明顯高出正常患者兩倍。
在這項最新研究中,研究者在實驗室中將藥物皂草素吸附到抗體上來靶向作用NAALADL2分子,從而破壞前列腺癌細胞;研究者Hayley Luxton博士表示,利用包埋毒性負荷物質的抗體,我們就能夠更清楚直觀地發現前列腺癌細胞含有較多NAALADL2分子;下一步我們計劃開發針對患者使用的新型療法。
每年在英國大約有4.65萬人被診斷為前列腺癌,又有大約1.1萬人死於該疾病;本文研究或將幫助研究者對癌症進行有效區分,當提及惡性前列腺癌時,我們都知道其發展非常緩慢,而且容易擴散,目前研究者迫切需要開發出新型療法來治療惡性的前列腺癌。更有意思的是,這項研究中研究者所發現的標誌物能夠幫助指示前列腺癌腫瘤是否是惡性的,對於後期研究者們開發新型靶向性療法或將提供新的思路和希望。(生物谷Bioon.com)

Marker for aggressive prostate cancer doubles up as a drug target
Researchers have discovered that a marker found on aggressive prostate cancer cells could also be used as a way to guide treatments to the cancer, according to new research presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool.
The molecule, called NAALADL2, is already measured to see if prostate cancer is likely to return, but the new study has shown that it can also help direct treatment to the cancer.
The team, based at UCL, had already found that prostate cancer cells have more of the NAALADL2 molecule on their surface compared to cells from healthy tissue. Prostate cancer patients whose tumour cells have high levels of this molecule are more than twice as likely to see their disease return following surgery.
In the new study, the researchers attached the drug saporin to an antibody targeted against NAALADL2 to destroy prostate cancer cells in the lab.
Dr Hayley Luxton, lead researcher from the Molecular Diagnostics and Therapeutics Laboratory at University College London, said: "Using antibodies mounted with a toxic payload, we can exploit the fact that aggressive prostate cancer cells have more NAALADL2.
