肿瘤靶向治疗基因检测临床应用结果
维生素 D 状态不足可能会增加患多种癌症的风险。流行病学研究表明 25-羟基维生素 D3 (25(OH)D3) 与包括结直肠癌在内的恶性肿瘤之间存在负相关。以前的研究表明,MED28 是一种参与转录调控的介质亚基,与结直肠癌细胞的生长有关。然而,目前尚不清楚其在结直肠癌上皮间质转化(EMT)和细胞迁移等转移进展中的作用。本研究的目的是研究骨化三醇、1,25-二羟基维生素 D3 (1,25(OH)2D3)(一种维生素 D 的生物活性形式)的潜在抑制作用,以及 MED28 在人类 EMT 进展中的作用大肠癌细胞。 MED28 的抑制增加了 E-cadherin 的表达并降低了几种间充质和迁移生物标志物以及 Wnt/β-catenin 信号分子的表达,而 MED28 的过表达增强了 EMT 特征。骨化三醇抑制 MED28 的表达,骨化三醇的作用反映了 MED28 沉默的作用。我们的数据表明,骨化三醇减弱了人类结直肠癌细胞中 MED28 介导的细胞生长和 EMT,强调了 MED28 在结直肠癌进展中的重要性并支持骨化三醇的潜在转化应用。

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.
