Integrated network pharmacology, bioinformatics, and experiment analysis to decipher the molecular mechanism of Salidroside on Gastric cancer via targeting NCOA4-mediated ferritinophagy.

Gastric cancer (GC) is a highly aggressive and heterogeneous malignancy. The process of ferroptosis regulates tumor growth and represents a promising therapeutic target for GCs. Despite Salidroside (Sal) being able to regulate ferroptosis in a variety of diseases, there are still limited reports on its therapeutic effects and potential targets in treating GC.

Structural Basis of High-Precision Protein Ligation and Its Application.

Enzyme-catalyzed protein modifications have become invaluable in diverse applications, outperforming chemical methods in terms of precision, conjugation efficiency, and biological compatibility. Despite significant advances in ligases, such as sortase A and OaAEP1, their use in heterogeneous biological environments remains constrained by limited target sequence specificity. In 2021, Lupas' group introduced Connectase, a family of repurposed archaeal proteases for protein ligations, but its low processivity and lack of structural information have impeded further engineering for practical biological and biophysical applications.

Efficacy and safety of Aurantii Fructus Immaturus flavonoid Tablets vs. domperidone for functional dyspepsia: a multicenter, double-blind, double-dummy, randomized controlled phase III trial.

Background: The clinical management of functional dyspepsia (FD) is challenging. This study evaluated the efficacy and safety of Aurantii Fructus Immaturus flavonoid (AFIF) tablets vs. domperidone for FD.

Ultrasound-assisted ionic liquid extraction of polysaccharides from Crataegus songarica K. Koch fruits: Structural characterization and Antioxidant Activity.

The optimal conditions determined were: ultrasonic power of 400 W, temperature of 79 ℃, extraction time of 78 min, Ethylammonium dodecyl sulfate (EADS) concentration of 1.

Supramolecular DNA Nanodevice Assembled via RCA and HCR Cascade Reaction on Tetrahedral DNA Nanostructure for Sensitive Detection and Intracellular Imaging of Dual-miRNAs Associated with Liver Cancer.

Herein, a supramolecular DNA nanodevice was formed via the rolling circle amplification (RCA) and hybridization chain reaction (HCR) cascade reaction on a tetrahedral DNA nanostructure (TDN) to achieve simultaneous sensitive detection and intracellular imaging of dual-miRNAs related to liver cancer. The supramolecular DNA nanodevice effectively addressed the limitations of low probe loading capacity in traditional TDN nanodevices by enriching plenty of signal probes around a single TDN, significantly enhancing the fluorescence signal. Impressively, the supramolecular DNA nanodevice with a TDN fulcrum and dense DNA structure imparted the nanodevice with strong rigidity, ensuring the stability of the signal probes to decrease aggregation quenching for further increasing the fluorescence response.
