Historically, gene expression has been shown to be the most informative data for drug response prediction. Recent evidence suggests that integrating additional omics can improve prediction accuracy which raises question of how integrate omics. Regardless integration strategy, clinical utility and translatability are crucial. Thus, we reasoned a multi-omics approach combined with datasets would relevance.

Background Machine learning and artificial intelligence have shown promising results in many areas are driven by the increasing amount of available data. However, these data often distributed across different institutions cannot be easily shared owing to strict privacy regulations. Federated (FL) allows training machine models without sharing sensitive In addition, implementation is time-consuming requires advanced programming skills complex technical infrastructures. Objective Various tools...

Hypertension and bronchial asthma are a major issue for people's health. As of 2014, approximately one billion adults, or ~ 22% the world population, have had hypertension. 2011, 235–330 million people globally been affected by 250,000–345,000 died each year from disease. The development effective treatment therapies against these diseases is complicated their comorbidity features. This often problem in diagnosis treatment. Hence, this study bioinformatical methodology analysis two...

Abstract Motivation The goal of pharmacogenomics is to predict drug response in patients using their single- or multi-omics data. A major challenge that clinical data (i.e. patients) with outcome very limited, creating a need for transfer learning bridge the gap between large pre-clinical datasets (e.g. cancer cell lines), as source domain, and target domain. Two discrepancies exist datasets: (i) input space, gene expression due difference basic biology, (ii) output different measures...

Abstract Asthma and hypertension are complex diseases coinciding more frequently than expected by chance. Unraveling the mechanisms of comorbidity asthma is necessary for choosing most appropriate treatment plan patients with this comorbidity. Since both have a strong genetic component in article we aimed to find study genes simultaneously associated hypertension. We identified 330 shared found that they form six modules on interaction network. A overlap between was level eQTL regulated...

Abstract Cancer is a heterogeneous disease characterized by unregulated cell growth and promoted mutations in cancer driver genes some of which encode suitable drug targets. Since the distinct set can vary between within types, evidence-based selection drugs crucial for targeted therapy following precision medicine paradigm. However, many putative not be directly, suggesting an indirect approach that considers alternative functionally related targets gene interaction network. Once potential...

Despite the significant progress in accuracy and reliability mass spectrometry technology, as well development of strategies based on isotopic labeling or internal standards recent decades, systematic biases originating from non-biological factors remain a challenge data analysis. In addition, wide range available normalization methods renders choice suitable method challenging. We systematically evaluated 17 two batch effect correction methods, originally developed for pre-processing DNA...

Clinical time-to-event studies are dependent on large sample sizes, often not available at a single institution. However, this is countered by the fact that, particularly in medical field, individual institutions legally unable to share their data, as data subject strong privacy protection due its particular sensitivity. But collection, and especially aggregation into centralized datasets, also fraught with substantial legal risks outright unlawful. Existing solutions using federated...

Abstract Motivation Identification of differentially expressed genes is necessary for unraveling disease pathogenesis. This task complicated by the fact that many diseases are heterogeneous at molecular level and samples representing distinct subtypes may demonstrate different patterns dysregulation. Biclustering methods capable identifying follow a similar expression pattern only in subset hence can consider heterogeneity. However, biologically significant reproducible sets remain...
