Prediction algorithms for protein or gene structures, including transcription factor binding from sequence information, have been transformative in understanding regulation. Here we ask whether human transcriptomic profiles can be predicted solely the expression of factors (TFs). We find that 1600 TFs explain >95% variance 25,000 genes. Using light-up technique to inspect trained NN, an over-representation known TF-gene regulations. Furthermore, learned prediction network has a hierarchical organization. A smaller set around 125 core could close 80% variance. Interestingly, reducing number below 500 induces rapid decline performance. Next, evaluated model using transcriptional data 22 diseases. The were sufficient predict dysregulation target genes (rho = 0.61, P < 10-216). By inspecting model, key causative extracted subsequent validation disease-associated genetic variants. demonstrate methodology constructing interpretable neural predictor, where analyses predictors identified inducing changes during disease.

Abstract Human coronaviruses (HCoVs), including severe acute respiratory syndrome coronavirus (SARS-CoV) and 2019 novel (2019-nCoV, also known as SARS-CoV-2), lead global epidemics with high morbidity mortality. However, there are currently no effective drugs targeting 2019-nCoV/SARS-CoV-2. Drug repurposing, representing an drug discovery strategy from existing drugs, could shorten the time reduce cost compared to de novo discovery. In this study, we present integrative, antiviral repurposing methodology implementing a systems pharmacology-based network medicine platform, quantifying interplay between HCoV–host interactome targets in human protein–protein interaction network. Phylogenetic analyses of 15 HCoV whole genomes reveal that 2019-nCoV/SARS-CoV-2 shares highest nucleotide sequence identity SARS-CoV (79.7%). Specifically, envelope nucleocapsid proteins two evolutionarily conserved regions, having identities 96% 89.6%, respectively, SARS-CoV. Using proximity interactions interactome, prioritize 16 potential anti-HCoV repurposable (e.g., melatonin, mercaptopurine, sirolimus) further validated by enrichment drug-gene signatures HCoV-induced transcriptomics data cell lines.

The global coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome 2 (SARS-CoV-2), has led to unprecedented social and economic consequences. risk of morbidity mortality due COVID-19 increases dramatically in the presence coexisting medical conditions, while underlying mechanisms remain unclear. Furthermore, there are no approved therapies for COVID-19. This study aims identify SARS-CoV-2 pathogenesis, manifestations, using network medicine methodologies along with clinical multi-omics observations. We incorporate virus–host protein–protein interactions, transcriptomics, proteomics into human interactome.

Ethnopharmacology, through the description of beneficial effects plants, has provided an early framework for therapeutic use natural compounds. Natural products, either in their native form or after crude extraction active ingredients, have long been used by different populations and explored as invaluable sources drug design. The transition from traditional ethnopharmacology to discovery followed a straightforward path, assisted evolution isolation characterization methods, increase computational power, development specific chemoinformatic methods. deriving extensive exploitation product chemical space led novel compounds with pharmaceutical properties, although this was not analogous drugs. In work, we discuss ideas silico discovery, applied products. We point out that, past, starting plant itself, identified sustained ethnopharmacological research, compound analysis testing. contrast, recent years, substance pinpointed methods (in docking molecular dynamics, network pharmacology), identification plant(s) containing ingredient, existing putative information. further stress potential pitfalls absolute need vitro vivo validation requirement.
