生物谷報(bào)道:剛剛出版的Cell上,美國(guó)冷泉港實(shí)驗(yàn)室Stephen J. Elledge及其同事剛剛采用基于RNAi方法的遺傳學(xué)篩選平臺(tái)鑒定出一個(gè)新的腫瘤抑制基因REST/NRSF,。本文的核心在于首次采用RNAi遺傳學(xué)平臺(tái)鑒定出重要的新基因,。他們采用這個(gè)平臺(tái)不僅確認(rèn)了以往認(rèn)為的兩個(gè)腫瘤抑制基因TGFBR2 和PTEN,同時(shí)鑒定出REST/NRSF,,這項(xiàng)實(shí)驗(yàn)的重要意義不僅在于發(fā)現(xiàn)了一個(gè)新的腫瘤抑制基因,,而且證實(shí)了基于RNAi平臺(tái)進(jìn)行遺傳基因的篩選是可行的,有效的,。
同期Cell上還刊登了新西蘭科學(xué)家一篇相似的文章,,也是通過RNAi平臺(tái)篩選出另一個(gè)腫瘤抑制基因,PITX1 ,,它是通過抑制RAS通路起作用的,。為此Cell專門發(fā)文進(jìn)行評(píng)論,稱贊RNAi平臺(tái)篩選基因是一個(gè)理想的工具,。
這是兩篇文章不同的思路比較:
Models for the mechanism of the tumor suppressive function of REST (A) and PITX1 (B). See text for details.
