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) and uridylated miR-143-3p|0|−1(+1U) (21 nt) were downregulated across all conditions, and applying padj < 0.05 alone additionally identified miR-143-3p|0|+1 (22 nt) and miR-143-3p|0|0(+1U) (22 nt). Upregulation of direct targets SERPINE1 and HK2 and glycolytic genes LDHA, GAPDH, and PKM was observed in all conditions. TUT4 overexpression combined with DICER1 downregulation indicates systemic dysregulation of microRNA biogenesis. Downregulation of miR-143-3p isoforms represents a universal hypoxic signal in trophoblasts driving glycolytic reprogramming in PE.

Исследование движения сферического фронта клеток в вязком матриксе: роль клеточных делений и взаимодействия клеток с матриксом при развитии опухолей

Logvenkov S. A., Известия РАН. Механика жидкости и газа 2026 № 3 С. 59–75

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 ...

Interpreting antiviral effects: from experimental measurements to mechanistic viral dynamics

Nersisyan A., Frontiers in Molecular Biosciences 2026 Vol. 13 Article 1995001

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 vibrational modes in G-quadruplexes reveal the mechanical properties of nucleic acids

Тукачев Н. В., González-Jiménez M., Ramakrishnan G. et al., Physical Chemistry Chemical Physics 2021 Vol. 23 No. 23 P. 13250–13260

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 ...

Динамика изолированного поселения Spermophilus Suslicus (Rodentia, Sciuridae) в Липецке (Европейская Россия), его перспективы и роль в сохранении вида

Батова О. Н., Савинецкая Л. Е., Проявка С. В. et al., Nature Conservation Research. Заповедная наука 2026 Т. 11 № 4 С. 25–39

Spermophilus suslicus is a threatened species listed in Red Data Books at all levels (from regional Red Data Books to the IUCN Red List of Threatened Species), and it currently requires special conservation activity. Over the past 30–50 years, its range has changed from continuous to mosaic, and its population has declined everywhere. In 2015, in Russia experimental ...

Detailed data on anatomy of the coelomic system and ultrastructure of the lophophore coelom in brachiopod Novocrania anomala with discussion of the phylogenetic significance

Temereva E., Zoologischer Anzeiger 2026 Vol. 325 P. 182–195

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 ...

HLA class I escape drives the evolution of SARS-CoV-2 in human populations

Ekaterina D. Riumina, Klink G. V., Alekseeva E. et al., PNAS, США 2026 Vol. 123 No. 35 P. 1–20

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 ...

A New Recruitable E3 Ligase UHRF1 Supporting Targeted Protein Degradation: A Minimal Azide as a Recruitment Ligand

Lin Z., Duan K., Wan R. et al., Advanced Science 2026 P. 1–13

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 ...

Physiological and molecular mechanisms of tolerance to hypoxia and oxygen deficiency resistance markers

Silina M., Dzhalilova D., Fokichev N. et al., Frontiers in Molecular Biosciences 2025 Vol. 12 Article 1674608

Humans and laboratory animals differ in their resistance to hypoxia, which affects the severity of inflammatory diseases and the rate of tumor progression. Therefore, it is necessary to search for methods for assessing the initial tolerance to oxygen deficiency and the risks of developing acute mountain sickness without direct hypoxia exposure on the organism. The ...

A three-dimensional (3D) matrix consisting of collagen fibers can create culture conditions that are more similar to in vivo tissues than 2D cultures in in vitro culture plates. Macrophages are among the most important innate immune cells. They are extremely plastic, allowing them to respond effectively to pro- and anti-inflammatory signals within their microenvironment. There ...

scRNA-seq of preeclamptic trophoblasts identifies EBI3, COL17A1, miR-27a-5p, and miR-193b-5p as hypoxia markers: validation of neuradapt as a superior mimetic to cobalt chloride

Knyazev E., Timur Kulagin, Antipenko I. et al., Placenta 2026 Vol. 176 P. 1–12

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 ...
