Bioinformatics for Dummies.
Bioinformatics– the process of searching biological databases, comparing sequences, examining protein structures, and researching biological questions with a computer– is one of the marvels of modern technology that can save you months of lab work. And the most amazing part is that, if you know how, you can use highly sophisticated programs over the Internet without paying a dime and sometimes, without installing anything new on your own computer. All you need to know is how to use these technological miracles. That's where Bioinformatics For Dummies comes in. If you want to know what bioinformatics is all about and how to use it without wading through pages of computer gibberish or taking a course full of theory, this book has the answers in plain English. You'll find out how to Use Internet resources Understand bioinformatics jargon Research biological databases Locate the sequences you need Perform specific tasks, step by step Written by two experts who helped develop the science, Bioinformatics For Dummies is all about getting things done. If you're just getting your feet wet, start at the beginning with a quick review of those necessary parts of microbiology and an overview of the tools available. If you already know what you want to do, you can go directly to a chapter that shows you how. Get the lowdown on Researching and analyzing DNA and protein sequences Gathering information from all published sources Searching databases for similar sequences and acquiring information about gene functions through sequence comparisons Producing and editing multiple sequence comparisons for presentation Predicting protein structures and RNA structures Doing phylogenetic analysis With an Internet connection and Bioinformatics For Dummies, you'll discover how to peruse databases that contain virtually everything known about human biology. It's like having access to the world's largest lab, right from your desk. This book is your lab assistant–one that never takes a day off, never argues when you ask it for help, and won't demand a benefits package.
2型糖尿病发病是环境因素与遗传因素相互作用的结果，已被鉴定与其相关的基因超过400个，这些基因也与肥胖、脂代谢紊乱和心血管病等密切相关。然而，目前检测出来的许多基因突变是低频率、罕见的变异，它们对总体疾病发生风险的作用尚未完全阐明，也缺乏相对应的靶向药物。 本研究主要是在前期研究基础上，期望能通过对个体基因组、蛋白质组、代谢组和临床表型的信息等进行多组学数据深度挖掘 (OWAS-DM)，利用GWAS关联的孟德尔遗传-蛋白组量化性状基因座 (MR-pQTL)，MR-mQTL (代谢组)，MR-eQTL (表型组) 共定位分析及生物信息学分析等多组学分析策略，发现2型糖尿病发生发展的潜在机制及标志物。并利用cMAP及分子对接等人工智能虚拟筛选技术结合基于实验的亲和质谱、表面等离子共振及高内涵等筛选技术，发展针对2型糖尿病靶标的高通量药物筛选技术，为糖尿病患者的个体化精准诊断和治疗提供新的手段。翻译成英文
精简下面表达：Existing protein function prediction methods integrate PPI networks and multivariate bioinformatics data to improve the performance of function prediction. By combining multivariate information, the interactions between proteins become diverse. Different interactions’ functions in functional prediction are various. Combining multiple interactions simply between two proteins can effectively reduce the effect of false negatives and increase the number of predicted functions, but it can also increase the number of false positive functions, which contribute to nonobvious enhancement for the overall functional prediction performance. In this article, we have presented a framework for protein function prediction algorithms based on PPI network and semantic similarity with the addition of protein hierarchical functions to them. The framework relies on diverse clustering algorithms and the calculation of protein semantic similarity for protein function prediction. Classification and similarity calculations for protein pairs clustered by the functional feature are more accurate and reliable, allowing for the prediction of protein function at different functional levels from different proteomes, and giving biological applications greater flexibility.The method proposed in this paper performs well on protein data from wine yeast cells, but how well it matches other data remains to be verified. Yet until now, most unknown proteins have only been able to predict protein function by calculating similarities to their homologues. The predictions result of those unknown proteins without homologues are unstable because they are relatively isolated in the protein interaction network. It is difficult to find one protein with high similarity. In the framework proposed in this article, the number of features selected after clustering and the number of protein features selected for each functional layer has a significant impact on the accuracy of subsequent functional predictions. Therefore, when making feature selection, it is necessary to select as many functional features as possible that are important for the whole interaction network. When an incorrect feature was selected, the prediction results will be somewhat different from the actual function. Thus as a whole, the method proposed in this article has improved the accuracy of protein function prediction based on the PPI network method to a certain extent and reduces the probability of false positive prediction results.
