    药物发现旨在寻找具有特定化学性质的用于治疗疾病的新化合物。在过去的几年里,在这个搜索中使用的方法提出了一个重要的组成部分,在计算机科学与机器学习技术的飞涨,由于其民主化。随着精准医学计划设定的目标和产生的新挑战,有必要建立健壮的,实现既定目标的标准和可重复的计算方法。目前,基于机器学习的预测模型在临床前研究之前的步骤中已经变得非常重要。这一阶段设法大大减少了发现新药的成本和研究时间。这篇综述文章的重点是如何在近年来的研究中使用这些新方法。分析该领域的最新技术将使我们了解在短期内化学信息学的发展方向,它所呈现的局限性和所取得的积极成果。这篇综述将主要关注用于对分子数据进行建模的方法,以及近年来解决的生物学问题和用于药物发现的机器学习算法。
    Drug discovery aims at finding new compounds with specific chemical properties for the treatment of diseases. In the last years, the approach used in this search presents an important component in computer science with the skyrocketing of machine learning techniques due to its democratization. With the objectives set by the Precision Medicine initiative and the new challenges generated, it is necessary to establish robust, standard and reproducible computational methodologies to achieve the objectives set. Currently, predictive models based on Machine Learning have gained great importance in the step prior to preclinical studies. This stage manages to drastically reduce costs and research times in the discovery of new drugs. This review article focuses on how these new methodologies are being used in recent years of research. Analyzing the state of the art in this field will give us an idea of where cheminformatics will be developed in the short term, the limitations it presents and the positive results it has achieved. This review will focus mainly on the methods used to model the molecular data, as well as the biological problems addressed and the Machine Learning algorithms used for drug discovery in recent years.

    非编码RNA通过影响基因表达和翻译来控制细胞功能,它们的失调与改变的细胞稳态和疾病有关。包括癌症.具有抗癌治疗潜力的营养食品已被证明可以调节非编码RNA的表达,这可能会影响与恶性表型有关的基因的表达。
    这里,我们报告了microRNAs(miRNAs)和长链非编码RNAs(lncRNAs)的微阵列分析,以及在暴露于白藜芦醇(RV)24小时的OVCAR-3卵巢癌细胞中潜在调节的相关生化途径和功能过程,一种在各种人类和动物模型中被证明可以抑制癌症发生和癌症进展的营养食品,在体外和体内。采用Diana工具和基因本体论(GO)途径分析以及Pubmed文献检索来鉴定可能受失调的miRNA和lncRNA影响的细胞过程。
    目前的数据一致支持以下观点:RV可以通过非编码RNA表观遗传调节控制细胞稳态的途径发挥抗肿瘤活性,细胞增殖,细胞死亡和细胞运动。
    UNASSIGNED: Non-coding RNAs control cell functioning through affecting gene expression and translation and their dysregulation is associated with altered cell homeostasis and diseases, including cancer. Nutraceuticals with anti-cancer therapeutic potential have been shown to modulate non-coding RNAs expression that could impact on the expression of genes involved in the malignant phenotype.
    UNASSIGNED: Here, we report on the microarray profiling of microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) and on the associated biochemical pathways and functional processes potentially modulated in OVCAR-3 ovarian cancer cells exposed for 24 h to Resveratrol (RV), a nutraceutical that has been shown to inhibit carcinogenesis and cancer progression in a variety of human and animal models, both in vitro and in vivo. Diana tools and Gene Ontology (GO) pathway analyses along with Pubmed literature search were employed to identify the cellular processes possibly affected by the dysregulated miRNAs and lncRNAs.
    UNASSIGNED: The present data consistently support the contention that RV could exert anti-neoplastic activity via non-coding RNAs epigenetic modulation of the pathways governing cell homeostasis, cell proliferation, cell death and cell motility.
