Potassium/sodium cation carriers robustly up-regulate CD20 antigen by targeting MYC, and synergize with anti-CD20 immunotherapies to eliminate malignant B cells.

Our investigation uncovers that nanomolar concentrations of salinomycin, monensin, nigericin, and narasin (a group of potassium/sodium cation carriers) robustly enhance surface expression of CD20 antigen in B-cell-derived tumor cells, including primary malignant cells of chronic lymphocytic leukemia and diffuse large B-cell lymphoma. Experiments in vitro, ex vivo, and animal model reveal a novel approach of combining salinomycin or monensin with therapeutic anti-CD20 monoclonal antibodies or anti-CD20 CAR-T cells, significantly improving non- Hodgkin lymphoma (NHL) therapy. The results of RNA-seq, genetic editing, and chemical inhibition delineate the molecular mechanism of CD20 upregulation, at least partially, to the downregulation of MYC, the transcriptional repressor of the MS4A1 gene encoding CD20.

Combination of flaxseed and clarified tomato juice in bread: Delayed effect on metabolic disorders during long-term unbalanced diet in an in vivo experiment.

Objective: The of study was to evaluate the biological effects occurring in the animal body in conditions of a regular consumption of bread with a combination of flaxseed and clarified tomato juice in its composition.

Methods: The animals (Soviet Chinchilla breed) were randomly distributed between six groups. Group 1 is intact animals.

Change in Activities of Enzymes of Energy and Carbohydrate Metabolism in Pink Salmon Oncorhynchus gorbuscha (Walb.) Smolts with Change in Environmental Salinity.

Activities of key enzymes of energy and carbohydrate metabolism (cytochrome c oxidase (COX), lactate dehydrogenase (LDH), aldolase, glucose 6-phosphate dehydrogenase (G6PDH), and 1-glycerophosphate dehydrogenase (1-GPDH)) were studied in pink salmon Oncorhynchus gorbuscha (Walb.) smolts from the White Sea in a cage experiment simulating the transition from a freshwater to a marine environment. A decrease in COX, G6PDH, and 1-GPDH activities and an increase in LDH and aldolase activities were observed in juveniles with an increase in water salinity.

Exploring the heteroanionic 2D materials RhSeCl and RhTeCl as promising semiconductor materials.

Heteroanionic materials show promising potential as 2D semiconductors due to their tunable band gaps, making them excellent candidates for photocatalytic water splitting applications. We conducted detailed theoretical and experimental analysis of two selected materials by synthesizing crystals through chemical vapor transport and investigating the impact of anion variation on crystal structure and properties. Using powder X-ray diffraction and convergent beam electron diffraction, we elucidated the non-centrosymmetric space groups of these compounds.
