Interaction of Liposomes Containing the Carrageenan/Echinochrome Complex with Human HaCaT Keratinocytes In Vitro.

Liposomal drug delivery systems are successfully used in various fields of medicine for external and systemic applications. Marine organisms contain biologically active substances that have a unique structure and exhibit a wide range of biological activities. Polysaccharide of red seaweed (carrageenan (CRG)), and water-insoluble sea urchin pigment (echinochrome (Ech)) interact with each other and form a stable complex.

Agropine-type rolA modulates ROS homeostasis in an auxin-dependent manner in rolA-expressing cell cultures of Rubia cordifolia L.

Long-term cultured calli may experience a biosynthetic shift due to the IAA-dependent expression of the rolA gene, which also affects ROS metabolism. The "hairy root" syndrome is caused by the root-inducing Ri-plasmid of Rhizobium rhizogenes, also known as Agrobacterium rhizogenes. The Ri-plasmid contains genes known as rol genes or root oncogenic loci, which promote root development.

Exosome-like Nanoparticles, High in Trans-δ-Viniferin Derivatives, Produced from Grape Cell Cultures: Preparation, Characterization, and Anticancer Properties.

: Recent interest in plant-derived exosome-like nanoparticles (ENs) has surged due to their therapeutic potential, which includes antioxidant, anti-inflammatory, and anticancer activities. These properties are attributed to their cargo of bioactive metabolites and other endogenous molecules. However, the properties of ENs isolated from plant cell cultures remain less explored.

Lectins CGL and MTL, representatives of mytilectin family, exhibit different antiproliferative activity in Burkitt's lymphoma cells.

Lectins are carbohydrate-binding proteins, whose biological effects are exerted via binding to glycoconjugates expressed on the surface of cells. Exposure to lectins can lead not only to a change in the structure and properties of cells but also to their death. Here, we studied the biological activity of lectins from the mussels Crenomytilus graynus (CGL) and Mytilus trossulus (MTL) and showed that these proteins can affect the proliferation of human lymphoma cells.

Description of Two New Species of Ehrenberg (Naviculales, Bacillariophyceae) from the Russian Far East Using an Integrative Approach.

(Naviculales, Bacillariaceae) are widespread, mostly in fresh-water habitats, and account for 343 species. They are described mainly on the basis of morphology and morphometric traits. These characteristics vary during life cycles and may overlap between species, making their identification difficult.
