Some restriction–modification systems contain two DNA methyltransferases. In the present work, we have
classified such systems according to the families of catalytic domains present in the restriction endonucleases and both DNA methyltransferases. Evolution of the restriction–modification systems containing an endonuclease with a NOV_C family domain and two DNA methyltransferases, both with DNA_methylase family domains, was investigated in detail. Phylogenetic tree of DNA methyltransferases from the systems of this class consists of two clades of the same size. Two DNA methyltransferases of each restriction–modification system of this class belong to the different clades. This indicates independent evolution of the two methyltransferases. We detected multiple cross-species horizontal transfers of the systems as a whole, as well as the cases of gene transfer between the systems.

The role of escape from the cytotoxic T cell (CTL) response in SARS-CoV-2 evolution remains controversial. Here, we study the origin and spread of SARS-CoV-2 variants whose mutations reduce presentation by the HLA class I alleles common in human populations. We find that 35% of mutations that are characteristic of the variants of concern, and ...

Introduction. The active integration of rapidly developing omics and computer technologies in the 21st century has led to a breakthrough in understanding the principles of the functioning of living systems. One of the dynamically developing integrative areas in biology is biological modeling. The fundamental paradigm has been the methodology that allows for the prediction of ...

Targeted protein degradation represents a promising therapeutic strategy, yet its broader application is often limited by the scarcity of usable E3 ligases. Glutathione peroxidase 4 (GPX4) is a key target for inducing ferroptosis, but achieving sustained and potent inhibition remains challenging with conventional enzymatic inhibitors. Herein, we report the first small‐molecule GPX4 degraders that incorporate ...

Accurate classification of a patient with pulmonary hypertension (PH) into one of five groups is fundamental for appropriate disease management strategies. The time from disease onset to correct diagnosis is unacceptably long in many cases. Chronic thromboembolic pulmonary hypertension (CTEPH) develops as a consequence of venous thromboemboli, resulting in a more pronounced hereditary predisposition to ...

Центромеры обеспечивают расхождение хромосом, однако организацию их хроматина в пределах повторяющейся альфа-сателлитной ДНК долгое время было трудно изучать. Для решения этой задачи мы создали гаплотип-разрешённые аннотации сателлитной ДНК для полной диплоидной сборки генома человека T2T-HG002. Затем с помощью метода направленного метилирования с секвенированием длинных прочтений (DiMeLo-seq) мы картировали центромерный белок A (CENP-A), модификацию H3K9me3 и ...

The common marmoset is a New World monkey widely used to study primate evolution and human disease. We present a telomere-to-telomere (T2T) reference assembly for the species, plus three near-T2T haplotypes. These resolve previously inaccessible regions, including the centromeres, sex chromosomes, subterminal satellites, acrocentric chromosomes, and the major histocompatibility complex (MHC). We find marmoset centromeres ...

Background Therapeutic peptides exert pivotal effects in diverse biological processes, and have attracted significant interest in the field of biomedicine in recent years. However, most existing methods often fail to adequately capture the intricate interactions among amino acid residues and the contextual dependencies within peptide sequences, which hampers the extraction of deep semantic representations and ...

Receptive speech is the ability to understand speech addressed to a person. It is a crucial process for a child’s cognitive development. We examine the relationship between receptive speech and neural tracking of natural speech in 52 children aged 3–8 years to infer the neurophysiological mechanisms underlying speech development. We registered a 32-channel electroencephalogram (EEG) ...

Preeclampsia (PE) is a severe obstetric complication caused by chronic placental ischaemia. Genome-wide profiling of microRNA isoforms in two trophoblast hypoxia models (CoCl2 and the oxyquinoline derivative neuradapt, BeWo b30 cells) and clinical PE samples (placental tissue, syncytiotrophoblast vesicles) revealed concordant downregulation of hsa-miR-143-3p isoforms. Under a strict fold-change threshold, the canonical isoform (21 nt) ...

Clarity of knowledge and reasoning is necessary in many cases. Yet vagueness in scientific thinking related to surprise, curiosity, "ability to engage with not-knowing" (de Freitas) and abductive reasoning is also a crucially important source of scientific creativity which supplements combinatorial logic when dealing with the already known. Starting from studies by C. S. Peirce ...

Deciphering the evolutionary history of genes is foundational for biomedical research, enabling the identification of compensatory mutations in disease-associated genes and the selection of evolutionarily relevant model organisms. However, challenges of multi-isoform handling, the presence of incomplete genomes/proteomes initial datasets, and problems of evolutionary history representation are still present. To address these issues, we introduce ...

Bacteria have evolved a sophisticated array of signal transduction systems that allow them to adapt their physiology and metabolism to changing environmental conditions. Typically, these systems recognize signals through dedicated ligand binding domains (LBDs) to ultimately trigger a diversity of physiological responses. Nonetheless, an increasing number of reports reveal that signal transduction receptors also bind ...

Many proteins need recognition of specific DNA sequences for functioning. The number of recognition sites and their distribution along the DNA might be of biological importance. For example, the number of restriction sites is often reduced in prokaryotic and phage genomes to decrease the probability of DNA cleavage by restriction endonucleases. We call a sequence ...
