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 ...

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 ...

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 ...

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 ...

Background: Combined non-viral gene therapy (GT) of ischemia and cardiovascular disease is a promising tool for potential clinical translation. In previous studies our group has developed combined gene therapy by vascular endothelial growth factor 165 (VEGF165) + hepatocyte growth factor (HGF). Our recent works have demonstrated that a bicistronic pDNA that carries both human HGF and VEGF165 coding sequences ...

Melanoma is one of the most aggressive and treatment-resistant tumors that responsible for majority of skin-cancer related deaths. Here we propose a combination of MEK inhibitor binimetinib with metformin as a promising therapy against human melanoma cells in vitro, including BRAF -mutated A375, Mel Z, and Mel IL cells, and NRAS-mutated Mel MTP and Mel ...

Введение. Возникновение резистентности и дальнейшая опухолевая прогрессия остаются актуальной проблемой в лечении меланомы кожи. Процесс аутофагии и эпителиально-мезенхимальный переход (ЭМП) тесно связаны между собой и играют ключевую роль в опухолевой прогрессии. Таргетное коингибирование МЕК и mTOR киназ является потенциальной мишенью для терапии меланомы, нацеленной на блокирование ЭМП.
Цель работы – изучение влияния ко-ингибирования МЕК и mTOR киназ ...

Благодаря появившимся новым фундаментальным данным наши представления о роли ангиогенеза и его молекулярных участниках изменились. Расшифрованы молекулярно-генетические механизмы активации сигнальных путей пролиферации, малигнизации, подавления апоптоза опухолевых клеток, осуществляемые посредством взаимодействия молекулы VEGF с ее рецепторами. Сменилась доктрина ангиогенеза. Ангиогенез стали рассматривать в аспекте механизма повышения анаплазии, ускорения пролиферации, формирования клона стволовых опухолевых клеток, высокорезистентных к ...

В опухолевом ангиогенезе официально признаны два основных механизма. Это образование сосудистых структур объединениями предшественников эндотелиальных клеток (ПЭК) или ангиобластов из циркулирующей периферической крови (1) и сосудистое кооптирование (2) с использованием предсуществующих сосудов. Определить доминирующий фенотип эндотелиальных клеток (ЭК), участвующих в неоангиогенезе увеальной меланомы (УМ), представляется очень важным из-за различной чувствительности разных ЭК к антиангиогенной терапии и их ...

Cell sheet (CS) technology has advantages for application in regenerative medicine as far as it allows effective and feasible delivery cells for therapeutic application.Cell sheets are minimal tissueengineered constructs that consist of viable cells and extracellular matrix proteins forming a solid multilayered structure. Their expressed therapeutic potential relies on better survival after delivery compared to injection of dispersed cells. This approach ...

Therapeutic angiogenesis is a promising strategy for relief of ischemic conditions, and gene
delivery was used to stimulate blood vessels’ formation and growth. We have previously shown
that intramuscular injection of a mixture containing plasmids encoding vascular endothelial growth

ischemic limb, and ecacy of ...
