腫瘤靶向治療基因檢測臨床應用結果

維生素 D 狀態(tài)不足可能會增加患多種癌癥的風險。流行病學研究表明 25-羥基維生素 D3 (25(OH)D3) 與包括結直腸癌在內(nèi)的惡性腫瘤之間存在負相關。以前的研究表明，MED28 是一種參與轉(zhuǎn)錄調(diào)控的介質(zhì)亞基，與結直腸癌細胞的生長有關。然而，目前尚不清楚其在結直腸癌上皮間質(zhì)轉(zhuǎn)化（EMT）和細胞遷移等轉(zhuǎn)移進展中的作用。本研究的目的是研究骨化三醇、1,25-二羥基維生素 D3 (1,25(OH)2D3)（一種維生素 D 的生物活性形式）的潛在抑制作用，以及 MED28 在人類 EMT 進展中的作用大腸癌細胞。 MED28 的抑制增加了 E-cadherin 的表達并降低了幾種間充質(zhì)和遷移生物標志物以及 Wnt/β-catenin 信號分子的表達，而 MED28 的過表達增強了 EMT 特征。骨化三醇抑制 MED28 的表達，骨化三醇的作用反映了 MED28 沉默的作用。我們的數(shù)據(jù)表明，骨化三醇減弱了人類結直腸癌細胞中 MED28 介導的細胞生長和 EMT，強調(diào)了 MED28 在結直腸癌進展中的重要性并支持骨化三醇的潛在轉(zhuǎn)化應用。

Inadequate vitamin D status may increase the risk of developing multiple types of cancer. Epidemiological studies suggest an inverse association between 25-hydroxyvitamin D3?(25(OH)D3) and malignancy, including colorectal cancer. Previous studies have suggested that MED28, a Mediator subunit involved in transcriptional regulation, is associated with the growth of colorectal cancer cells; however, its role in the progression of metastasis such as epithelial-mesenchymal transition (EMT) and cell migration of colorectal cancer is unclear at present. The aim of this study was to investigate a potentially suppressive effect of calcitriol, 1,25-dihydroxyvitamin D3?(1,25(OH)2D3), a bioactive form of vitamin D, and the role of MED28 in the progression of EMT in human colorectal cancer cells. Suppression of MED28 increased the expression of E-cadherin and reduced the expression of several mesenchymal and migration biomarkers and Wnt/β-catenin signaling molecules, whereas overexpression of MED28 enhanced the EMT features. Calcitriol suppressed the expression of MED28, and the effect of calcitriol mirrored that of MED28 silencing. Our data indicate that calcitriol attenuated MED28-mediated cell growth and EMT in human colorectal cancer cells, underlining the significance of MED28 in the progression of colorectal cancer and supporting the potential translational application of calcitriol.
