Abstract Rhodostomin (Rho) and Trimucrin (Tmu) are RGD-containing disintegrins that inhibit integrins more effectively than short RGD peptides. They differ in their linker, RGD loop, and C-terminal sequences. We determin...

Background-Although PBL is effective in biology learning, this approach often triggers cognitive overload when the complexity of the material and instructional demands exceed students' working memory capacity, while ther...

Flower morphology, nectary structure, nectar chemical composition, breeding system, floral visitors and pollination were analysed in Croton sarcopetalus, a diclinous-monoecious shrub from Argentina. Male flowers have fiv...

Abstract Populus species are crucial for forestry and industry, yet poplar rust limits their growth. The molecular basis of rust resistance remains poorly understood. This study identified 203 AP2/ERF genes in the Populu...

Macromolecular crystallography provides mechanistic understanding of biological processes and can be applied in drug design. Nowadays, the use of robotic systems for crystal growth and diffraction analysis is widespread ...

Abstract Ornithine lipids (OLs) are phosphorus-free membrane lipids present in many bacteria, but absent from eukaryotes and archaea. Three pathways for OL synthesis have been reported to date. Conditions that induce OL ...

ABSTRACT Biofilms play a crucial role in medical, industrial, and environmental microbiology, yet their structural complexity often makes them challenging to study in undergraduate teaching laboratories. We present a sim...

The complement system is a blood-based immune network that plays a crucial role in fighting infection and maintaining immune homeostasis. The membrane attack complex (MAC) is a pore assembled from complement proteins tha...

Immunophilins are a family of proteins whose signature domain is the peptidylprolylisomerase domain. High molecular weight immunophilins are characterized by the additional presence of tetratricopeptide-repeats (TPR) thr...

In spite of their central role in orchestrating immunity, dendritic cells (DCs) can also limit harmful reactions and promote immune tolerance by inducing T cell anergy or favoring the differentiation of T regulatory (Tre...

Differential scanning fluorimetry (DSF) using the inherent fluorescence of proteins (nDSF) is a popular technique to evaluate thermal protein stability in different conditions (e.g. buffer, pH). In many cases, ligand bin...

The illumination of azobenzene molecules with UV/visible light efficiently converts the molecules between trans and cis isomerization states. Isomerization is accompanied by a large photo-induced molecular motion, which ...

Multiple myeloma (MM) is best understood as a dynamically evolving genomic ecosystem shaped by inherited susceptibility, early oncogenic events, and continuous selective pressures. We propose an evolutionary genomics fra...

Abstract Background Cumulus granulosa cells (CGCs) are essential for oocyte support, metabolic cooperation, and steroidogenesis, yet they deteriorate rapidly in conventional 2D culture, limiting long-term studies of thes...

Immune responses and inflammation are not stand-alone processes linearly regulated by the canonical signaling pathways but complex systems biology events, which are deeply rooted in the metabolic state of cells and dynam...

ABSTRACT Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by disrupted neuronal circuit maturation. Emerging evidence implicates microglial function and mitochondrial regulation as contribut...

Abstract Recent advances in protein structure prediction have opened new avenues for understanding the potential impact of genetic mutations and how they might affect protein structure. In this study, we analyzed the dis...

Abstract Among the epidermal growth factor receptor tyrosine kinases (EGFR) family, HER3 (Human epidermal growth factor receptor3) stands apart due to its minimal inherent intracellular kinase function. Its kinase domain...
