Homology modelling has matured into an important technique in structural biology, significantly contributing to narrowing the gap between known protein sequences and experimentally determined structures. Fully automated workflows servers simplify streamline homology process, also allowing users without a specific computational expertise generate reliable models have easy access results, their visualization interpretation. Here, we present update SWISS-MODEL server, which pioneered field of...
A major bottleneck in our understanding of the molecular underpinnings life is assignment function to proteins. While experiments provide most reliable annotation proteins, their relatively low throughput and restricted purview have led an increasing role for computational prediction. However, assessing methods protein prediction tracking progress field remain challenging.We conducted second critical assessment functional (CAFA), a timed challenge assess that automatically assign function....
Abstract Motivation Understanding the molecular mechanisms of thermal stability is a challenge in protein biology. Indeed, knowing temperature at which proteins are stable has important theoretical implications, intimately linked with properties native fold, and wide range potential applications from drug design to optimization enzyme activity. Results Here, we present novel graph-theoretical framework assess based on structure without any priori information. In this approach describe as...
The emerging SARS-CoV-2 variants of concern (VOCs) may display enhanced transmissibility, more severity and/or immune evasion; however, the pathogenesis these new VOCs in experimental models or potential infection other animal species is not completely understood. Here we infected K18-hACE2 transgenic mice with B.1, B.1.351/Beta, B.1.617.2/Delta and BA.1.1/Omicron isolates demonstrated heterogeneous infectivity pathogenesis. B.1.351/Beta variant was most pathogenic, while led to lower viral...
Abstract Haematopoietic stem cell (HSC) transplantation (HSCT) is the only curative treatment for a broad range of haematological malignancies, but standard care relies on untargeted chemotherapies and limited possibilities to treat malignant cells after HSCT without affecting transplanted healthy 1 . Antigen-specific cell-depleting therapies hold promise much more targeted elimination diseased cells, as witnessed in past decade by revolution clinical practice B malignancies 2 However,...
There is a wide interest in designing peptides able to bind specific region of protein with the aim interfering known interaction or as starting point for design inhibitors. Here we describe PepComposer, new pipeline computational binding given surface. PepComposer only requires target structure and an approximate definition site input. We first retrieve set peptide backbone scaffolds from monomeric proteins that harbor same arrangement interest. Next, optimal sequences identified scaffolds....
Targeted eradication of transformed or otherwise dysregulated cells using monoclonal antibodies (mAb), antibody–drug conjugates (ADC), T cell engagers (TCE), chimeric antigen receptor (CAR) is very effective for hematologic diseases. Unlike the breakthrough progress achieved B malignancies, there a pressing need to find suitable antigens myeloid malignancies. CD123, interleukin-3 (IL-3) alpha-chain, highly expressed in various hematological including acute leukemia (AML). However, shared...
Abstract Background The co-administration of drugs known to interact greatly impacts morbidity, mortality, and health economics.

Background. Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous condition. We hypothesized that the unbiased integration of different COPD lung omics using novel multi-layer approach may unravel mechanisms associated with clinical characteristics. Methods. profiled mRNA, miRNA and methylome in tissue samples from 135 former smokers COPD. For each omic (layer) we built patient network based on molecular similarity. The three networks were used to build network, optimization...

Abstract Background Neoantigens are patient- and tumor-specific peptides that arise from somatic mutations. They stand as promising targets for personalized therapeutic cancer vaccines. The identification process neoantigens has evolved with the use of next-generation sequencing technologies bioinformatic tools in tumor genomics. However, in-silico strategies selecting immunogenic still have very low accuracy rates, since they mainly focus on predicting peptide binding to Major...

Abstract Motivation: Predicting the structure of protein loops is very challenging, mainly because they are not necessarily subject to strong evolutionary pressure. This implies that, unlike rest protein, standard homology modeling techniques effective in their structure. However, often involved function, hence inferring important for predicting as well function. Results: We describe a method, LoopIng, based on Random Forest automated learning technique, which, given target loop, selects...
Abstract Hypocotyl elongation is influenced by light and hormones, but the molecular mechanisms underlying this process are not yet fully elucidated. We had previously suggested that Arabidopsis DOF transcription factor DAG1 may be a negative component of mechanism light-mediated inhibition hypocotyl elongation, as light-grown dag1 knock-out mutant seedlings show significant shorter hypocotyls than wild type. By using high-throughput RNA-seq, we compared transcriptome profile type seedlings....
