維生素 D 狀態(tài)不足可能會(huì)增加患多種癌癥的風(fēng)險(xiǎn)。流行病學(xué)研究表明 25-羥基維生素 D3 (25(OH)D3) 與包括結(jié)直腸癌在內(nèi)的惡性腫瘤之間存在負(fù)相關(guān)。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(jié)直腸癌細(xì)胞的生長(zhǎng)有關(guān)。然而，目前尚不清楚其在結(jié)直腸癌上皮間質(zhì)轉(zhuǎn)化（EMT）和細(xì)胞遷移等轉(zhuǎn)移進(jìn)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(jìn)展中的作用大腸癌細(xì)胞。 MED28 的抑制增加了 E-cadherin 的表達(dá)并降低了幾種間充質(zhì)和遷移生物標(biāo)志物以及 Wnt/β-catenin 信號(hào)分子的表達(dá)，而 MED28 的過(guò)表達(dá)增強(qiáng)了 EMT 特征。骨化三醇抑制 MED28 的表達(dá)，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(jié)直腸癌細(xì)胞中 MED28 介導(dǎo)的細(xì)胞生長(zhǎng)和 EMT，強(qiáng)調(diào)了 MED28 在結(jié)直腸癌進(jìn)展中的重要性并支持骨化三醇的潛在轉(zhuǎn)化應(yīng)用。

腫瘤發(fā)生與反復(fù)轉(zhuǎn)移國(guó)際數(shù)據(jù)庫(kù)描述：

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.
