Abstract Colorectal cancers are believed to arise predominantly from adenomas. Although these precancerous lesions have been subjected extensive clinical, pathologic, and molecular analyses, little is currently known about the global gene expression changes accompanying their formation. To characterize processes underlying transformation of normal colonic epithelium, we compared transcriptomes 32 prospectively collected adenomas with those mucosa same individuals. Important differences...

RNA molecules play fundamental roles in cellular processes. Their function and interactions with other biomolecules are dependent on the ability to form complex three-dimensional (3D) structures. However, experimental determination of 3D structures is laborious challenging, therefore, majority known RNAs remain structurally uncharacterized. Here, we present SimRNA: a new method for computational structure prediction, which uses coarse-grained representation, relies Monte Carlo sampling...

Intrinsically unstructured proteins (IUPs) lack a well-defined three-dimensional structure. Some of them may assume locally stable structure under specific conditions, e.g. upon interaction with another molecule, while others function in permanently state. The discovery IUPs challenged the traditional protein paradigm, which stated that defines protein. As December 2011, approximately 60 methods for computational prediction disorder from sequence have been made publicly available. They are...

Abstract SARS-CoV-2 is a betacoronavirus with linear single-stranded, positive-sense RNA genome, whose outbreak caused the ongoing COVID-19 pandemic. The ability of coronaviruses to rapidly evolve, adapt, and cross species barriers makes development effective durable therapeutic strategies challenging urgent need. As for other viruses, genomic structures are expected play crucial roles in several steps coronavirus replication cycle. Despite this, only handful functionally-conserved...

RNA is a large group of functionally important biomacromolecules. In striking analogy to proteins, the function depends on its structure and dynamics, which in turn encoded linear sequence. However, while there are numerous methods for computational prediction protein three-dimensional (3D) from sequence, with comparative modeling being most reliable approach, very few such RNA. Here, we present ModeRNA, software tool 3D structures. As an input, ModeRNA requires template molecule, sequence...
