Furthermore, these innovative new technologies may also help to identify the leads for therapeutic intervention, and to predict the new emergence of novel genotype/pathotypes with altered virulence and most importantly aid the development of effective vaccines [11]. Genomic tools, such as high-throughput sequencing, viral and host mRNA and microRNA expression profiling, and microarray-based analysis of pathogen and host single nucleotide polymorphisms will prove to be important methods not only in revealing the patterns of circulation but also the mechanisms of the pathogenesis of HPAI H5N1 viruses among wildlife populations.

Although survival times and other clinical endpoints are available for those treatments the patients were given over the course of their clinical management, these samples have not been subjected to a large-scale drug sensitivity profiling using laboratory assays. In addition to the cancer cell line panels, genomic and molecular profiling has also been performed in patient tumor samples. The number of patients for each tissue type ranges from 36 to 1100 (Table 1). For instance, TCGA provides a comprehensive cohort of omics and clinical information, across 33 different cancer types, consisting of genomic, molecular, proteomic, and clinical features of >11,000 cancer patients, with the aim to enhance understanding of cancer mechanisms for improved diagnosis and treatment options.

This indicates that the viruses might be transmitted to Qinghai Lake from poultry in southern China via a single introduction [18]. From the first H5N1 outbreak among waterfowl populations in 2005 at Qinghai Lake, four isolates were sequenced. This suggested that the viruses might be created from reassortants that originated in birds over-wintering in Southeast Asia [19]. Phylogenetic analysis showed that five of the eight genomic segments (M, PA, PB1, PB2, and NS) were closely related to a Hong Kong isolate (A/peregrine falcon/HK/D0028/04). Another independent study showed that the HA and NA genes of the Qinghai isolates and other H5N1 viruses from poultry in Fujian, Guangdong, Hunan and Yunnan provinces from 2005 were similar to the H5N1 virus A/Chicken/Shantou/4231/2003, while the internal genes were closely related to H5N1 viruses from poultry described in southern China during 2005 (e.g. A/Chicken/Shantou/810/2005).

Current models vary greatly with regard to cost, technical demands, recapitulated BBB aspects, and intended applications. The development of models that more closely resemble the human BBB will be important in gaining new insight into the structure and function of the BBB and its role in development and disease. Here, we have reviewed the components of the NVU and discussed approaches to model the BBB. However, there is a critical need to engineer more representative human BBB models capable of recapitulating BBB function and dysfunction. This will require integration of recent advances in stem cell technology with advances in microvessel microfabrication. In vitro BBB models can provide valuable information by serving as a high-throughput complement to animal models.

It does so through a pairwise comparison between any two decoys. Although this approach takes more computing time than ranking single scores directly, it is more sensitive to capture the differences among models and less prone to systematic errors of single scores on the decoys. Our method tries to capture the correlation between score differences and actual structural quality difference as well as the complementarity among these scores. Consensus GDT method depends on the decoy distribution and relies on geometric information of protein structures only, while single scoring functions produce a wide range of values for different decoys, which makes their scores unstable and noisy. Because of using single score information, PWCom is more correlated to the real GDT score with respect to the native structure than consensus methods. Our new approach combines the advantages of consensus GDT method and single scoring functions through pairwise comparison and a two-stage machine-learning scheme.

Model 2 was tested only on the pairs that were predicted to be significantly different by Model 1. Two neural-network models were used to compare a decoy pair. After the comparison between all pairs of decoys, the final score, named as PWCom, for each decoy was simply the number of winning times during the pair-wise comparisons. 4. Model 2 was used to predict whether one decoy was better than the other. The training and testing were done in a leave-one-out manner at protein (target) level, which meant each target (decoy set) was tested on the models trained on all other targets (decoy sets). We chose the cutoff to be 0.025, which meant that if the GDT difference of two decoys was larger than 0.025, they were treated as being significantly different. Model 1 was trained to determine whether two decoys were significantly different or not in terms of the GDT scores to their native. To train this model, considering the training error, we removed those of pairs wherein the GDT difference was less than 0.01 from training data. Both classifying neural networks had the same configuration, which is one hidden layer of 3 nodes with sigmoid activation functions, and same input feature vectors of five dimensions, each of which is specified by Eqn.

Interactions between these components contribute to the development and maintenance of the healthy BBB [6,7,8], although the relative contributions of each component and the specific mechanisms by which these processes occur is an area of active research, which will be discussed in more detail later. ECs in the CNS are supported structurally and functionally by pericytes, basement membrane, and astrocytes [5]. Paracellular transport is restricted by tight junctions (TJs) that stitch together adjacent ECs, while transcellular transport is regulated by a combination of specialized transporters and efflux pumps. The physical integrity of the barrier is derived from the endothelial cells (ECs) that line the brain microvasculature and tightly control paracellular and transcellular transport [2]. Transporters supply essential nutrients to the brain, while efflux pumps counter the passive entry of small molecules, including many toxins, but also many potential therapeutics.

Future in depth studies of the influenza reservoir, along with large-scale data mining of genomic resources and the integration of epidemiological, genomic, and antigenic data, should enhance our understanding of antigenic drift and improve the detection and control of the emerging novel strains [12]. Recent large-scale genome sequencing of HPAI H5N1 viruses, antigenic typing and database information mining have significantly improved the study of HPAI virus origin, diversity, transmission, reassortment and evolution.

The same applies to some extend also to genome-wide RNA-seq transcriptomics and especially to the MS-based global proteomic profiling, which would benefit from standardized analytical approaches to extract more accurate and complete gene expression and protein activity profiles. With regard to other cancer or drug classes, which especially require multi-marker panels, the microarray-based gene expression and targeted protein abundance profiles appear currently as the most predictive source of signal (Costello et al. This is likely due to the fact that these profiling platforms have been around for some time already, and available tailored processing methods have been developed for these. 2018). Similarly, a recent transcript-level machine learning work demonstrates how the RNA-seq technology offers additional predictive signal, when compared to gene-level expression or mutation information (Safikhani et al. For the more recent NGS-based platforms, such as DNA copy number or point mutations, we are still lacking the knowledge of how to best utilize all the hidden nuggets of information available from the raw sequencing data for drug response prediction; instead, one needs to rely only on the most processed, limited gene-level data available (Table 1). 2014). Therefore, we argue that we will need improvements both in the computational methods and in the experimental assays in order to convincingly show the added value of big data for drug response prediction. 2012; Pemovska et al. 2017). For example, our pilot study showed that the MS-based proteomics can significantly improve the drug response predictions, but only after filtering out most of the protein measurements (Ali et al. Based on the lessons learned from the DREAM Challenges and other related benchmarking studies, the NGS-based big data is not yet among the most predictive genomic or molecular features for drug response prediction globally, except for the few known examples of cancer types that are driven by single somatic aberrations, such as BCR-ABL-positive chronic myeloid leukemia, non-small cell lung cancer or BRAF in melanoma, with clinically actionable small-molecule inhibitors available (Flaherty et al. 2015).
