The microRNA profile in the blood plasma of menopausal women with insomnia (according to the Pittsburgh Sleep Quality Index questionnaire) was studied in two stages with 15 participants in each and an interval of 12 months. Both stages involved 12 women, and no transition from one group to another was detected in the second stage of the study. More than 4000 microRNAs and their isoforms were detected in the groups. It was found that only miR-412-5p significantly differed between the comparison groups, both in the first and second stages of the study ( p < 0,05). Analysis of metabolic pathways showed that three miR-412-5p target genes - FUT4 , FUT1 , and ST3GAL6 - are included in the Glycosphingolipid biosynthesis - lacto and neolacto series (hsa00601) pathway ( p = 0,87 × 10-16). It can be suggested that miR-412-5p represents a promising target for the development of treatments for insomnia.

The problem of the evolution of cell volume fraction in a spherical aggregate composed of cells,
extracellular matrix, and fluid is considered. The aggregate is surrounded by extracellular matrix. The
problem formulation employs a multiphase model of a biological continuum, previously developed by the
author, consisting of two actively interacting solid phases and a fluid. The propagation of ...

Antiviral activity is commonly summarized using endpoint measures such as EC50 or EC90, yet these quantities emerge from a dynamic biological system and depend on viral replication kinetics, host-cell properties, experimental design, and the assay used to quantify infection. Infectious-virus titers, viral RNA, infected-cell fractions, viability measurements, and immune readouts capture different components of the ...

Low-frequency vibrations play an essential role in biomolecular processes involving DNA such as gene expression, charge transfer, drug intercalation, and DNA–protein recognition. However, understanding the vibrational basis of these mechanisms relies on theoretical models due to the lack of experimental evidence. Here we present the low-frequency vibrational spectra of G-quadruplexes (structures formed by four strands ...

Brachiopoda is a group of animals, that is still insufficiently studied at the ultrastructural level, despite the significance of ultrastructure of tissues and organs for analysing the functional morphology, reconstructing the organisation and biology of numerous extinct brachiopods, and establishing relationships among major taxa. In the present study, we provide a revised reconstruction of the ...

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 ...

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) ...

Background. Preeclampsia (PE) complicates 2–8% of pregnancies and involves placental hypoxia and HIF-pathway activation, especially in early-onset PE (eoPE). Chemical mimetics like cobalt(II) chloride (CoCl2) and oxyquinoline derivatives model trophoblast hypoxia in vitro, yet their fidelity in recapitulating PE gene profiles remains unclear. Integrating patient tissue analyses with experimental models may reveal common markers and ...

It was recently found that the primary transcripts of some microRNA genes (pri-miRNAs) are able to express peptides with 12 to 40 residues in length. These peptides, called miPEPs, participate in the transcriptional regulation of their own pri-miRNAs. In our previous studies, we used bioinformatic approach for comparative analysis of pri-miRNA sequences in plant genomes ...

The role of the TGFβ signaling pathway, an important cascade responsible for the anti-inflammatory polarization of macrophages, in the development of both early- and late-onset preeclampsia (eoPE and loPE), remains poorly understood. In this study, we examined the components of the TGFβ signaling cascade and macrophage markers within placental tissue in normal pregnancy and in ...

Since its original discovery over a decade ago, extracellular RNA (exRNA) has been found in all biological fluids. Furthermore, extracellular microRNA has been shown to be involved in communication between various cell types. Importantly, the exRNA is protected from RNases degradation by certain carriers including membrane vesicles and non-vesicular protein nanoparticles. Each type of carrier ...

The classical view of gene regulation draws from prokaryotic models, where responses to environmental changes involve operons regulated by sequence-specific protein interactions with DNA, although it is now known that operons are also modulated by small RNAs. In eukaryotes, pathways based on microRNAs (miR) regulate the readout of genomic information from transcripts, while alternative nucleic ...

RNA interference in vertebrates acts as an antiviral mechanism only in undifferentiated embryonic stem cells and mediates through microRNAs. In somatic cells, microRNA host cells also bind to the genomes of RNA viruses, regulating their translation and replication. It has been shown that (+)RNA viruses are able to evolve under the influence of host cell ...

A widely used procedure for selecting significant miRNA-mRNA or isomiR-mRNA pairs out of predicted interactions involves calculating the correlation between expression levels of miRNAs/isomiRs and mRNAs in a series of samples. In this manuscript, we aimed to assess the validity of this procedure by comparing isomiR-mRNA correlation profiles in sets of sequence-based predicted target mRNAs ...
