Organoids can self-organize from tissue stem cells, primary cells, or pluripotent stem cells in a three-dimensional environment and partially reconstruct the cellular composition, spatial architecture, and functional characteristics of organs. They provide models that more closely resemble in ...
The fibrinolytic system selectively degrades cross-linked fibrin within thrombi by converting plasminogen into plasmin. Streptokinase, urokinase, and tissue-type plasminogen activator initiate this process through different mechanisms and exhibit clear differences in fibrin selectivity, duration ...
Induced pluripotent stem cells (iPSCs) have self-renewal and multilineage differentiation capacities and can be used in disease modeling, drug screening, organoid construction, and cell therapy research. Directed differentiation of iPSCs depends on stage-specific signal regulation. Activin A, ...
The superoxide anion radical (O₂•⁻) participates in redox signaling and also serves as an important precursor of hydrogen peroxide, peroxynitrite, and other reactive species. Because it is short-lived and highly reactive, detection results depend strongly on probe specificity, the reaction ...
Microorganisms can rapidly release excess carbon and generate ATP through acetate-producing pathways, while also activating extracellular acetate into acetyl-CoA. Phosphotransacetylase, acetate kinase, and acetyl-CoA synthetase jointly regulate acetate production, reutilization, and the ...
Cellulose degradation depends on the sequential cooperation of endoglucanases, cellobiohydrolases, and β-glucosidases. These enzymes are responsible for internal cleavage of cellulose chains, degradation from chain ends, and hydrolysis of cellobiose, respectively, and together determine the ...
Creatinine-related enzymes can convert creatinine into measurable products such as ammonia and hydrogen peroxide through direct deamination or multienzyme cascades, providing the reaction basis for biochemical renal function testing and enzyme sensor construction.
Nitrogen assimilation converts nitrate, nitrite, or ammonium into glutamine and glutamate, thereby supplying nitrogen for the synthesis of amino acids, nucleotides, and other nitrogen-containing compounds. Different key enzymes have clearly defined roles in substrate affinity, energy ...
Ribonucleases cleave RNA by recognizing specific bases, nucleic acid hybrid structures, or double-stranded RNA conformations, and have distinct application positions in nucleic acid purification, structural analysis, gene regulation, and disease mechanism research.
