Abstract
過去的研究顯示IL-8在許多癌症中都有異常的表現量。但是,IL-8在由Bcr-Abl所引起的慢性骨髓性白血病 (CML) 的作用至目前爲止仍屬未知。此外,我們過去的研究顯示於Bcr-Abl訊號下,IL-8是CD69和CD24的下游調控分子。本篇研究顯示,於CD34+人類臍帶血幹細胞和CML細胞株K562中,Bcr-Abl可以正調控IL-8的表現量。同時,在K562細胞中,CD69和CD24也被發現可以增加IL-8的promoter activity。另外,從IL-8 promoter analysis和染色體免疫沉澱(ChIP assay)中,我們也發現Bcr-Abl透過NF-κB和c-Jun,這兩個轉錄因子結合至IL-8 promoter上並誘導其表現。我們也再次證明在Bcr-Abl-transfecting CD34+人類臍帶血幹細胞中,CD69和CD24 knock-down可以增加由Bcr-Abl抑制劑,imatinib,所誘導的生長抑制和凋亡。但是,IL-8,這個CD69和CD24的下游分子,卻對K562 細胞的生長沒有作用。最後,我們也發現在K562細胞中,IL-8會抑制紅血球分化基因的mRNA表現,例如hemoglobin-α, hemoglobin-ζ 和CD71。本篇研究的價值在於,我們是第一個發現IL-8的表現量可以被Bcr-Abl/CD69/CD24 signaling pathway所調控。此外,IL-8可能扮演紅血球分化抑制的角色於Bcr-Abl positive細胞中。
