An update on the landscape of collagen bioactive fragments

The FEBS Journal, EarlyView.
The remodeling of the extracellular matrix releases collagen bioactive fragments, which exert molecular functions and regulate numerous biological processes via several signaling pathways. Here, we summarize the latest findings describing the roles of major bioactive fragments from collagens I, IV, VI, and XVIII in various physiological and ...

Intracellular Pool of Low- and Medium-Molecular-Weight Substances as a Nonspecific Integrative Indicator of Immunometabolism

Журнал медико-биологических исследований
Low- and medium-molecular-weight substances (LMMWS) and oligopeptides (OPs) constitute a pool of heterogeneous molecules formed during metabolic processes. These substances have been found to play a significant role in the development of metabolic shifts

Primary Step Towards In Situ Detection of Chemical Biomarkers in the UNIVERSE via Liquid-Based Analytical System: Development of an Automated Online Trapping/Liquid Chromatography System

Molecules, 2019
The search for biomarkers in our solar system is a fundamental challenge for the space research community. It encompasses major difficulties linked to their very low concentration levels, their ambiguous origins (biotic or abiotic), as well as their ...

Host‐Induced Silencing of Rhizoctonia Solani 5‐Enolpyruvylshikimate‐3‐Phosphate Synthase Impairs Its Virulence in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sheath blight disease of rice caused by the fungal pathogen R. solani AG1‐IA remains a big threat to rice production worldwide. A limited genetic variation in rice for tolerance to this pathogen and little success in understanding how it defeats host defence are major reasons behind it.

Isolation and characterization of peptides from blood serum of patients with multiple sclerosis

Біологічні студії, 2015
In order to find novel molecular markers of multiple sclerosis we developed a scheme of oligopeptides’ isolation including their extraction from blood serum with 10 % trichloroacetic acid, followed by precipitation of soluble substances with acetone in ...

Iron homeostasis in the annual and perennial stem zones of Arabis alpina

Plant Biology, EarlyView.
Iron accumulates in secondary growth tissues in the perennial stem zone and is correlated with particular gene expression patterns in the perennial model plant Arabis alpina. Abstract Plants store nutrients, including the micronutrient iron, in bioavailable forms to support growth in subsequent seasons. The perennial lifestyle is preponderant in nature.

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Stepwise LCST‐Type Phase Separation in Mixtures of Short‐Chain Elastin‐Like Peptides With Minimal Structural Differences

Biopolymers, Volume 117, Issue 2, March 2026.
Small differences in chain‐length or topology induce stepwise phase separation in short‐chain ELP mixtures. ABSTRACT Elastin‐like peptides (ELPs) comprise repetitive pentapeptide sequences and exhibit liquid–liquid phase separation through lower critical solution temperature‐type behavior.
