Inhalable Carbonyl Sulfide Donor-Hybridized Selective Phosphodiesterase 10A Inhibitor for Treating Idiopathic Pulmonary Fibrosis by Inhibiting Tumor Growth Factor-β Signaling and Activating the cAMP/Protein Kinase A/cAMP Response Element-Binding Protein (CREB)/p53 Axis.

Idiopathic pulmonary fibrosis (IPF) is a debilitating, incurable, and life-threatening disease that lacks effective therapy. The overexpression of phosphodiesterase 10A (PDE10A) plays a vital role in pulmonary fibrosis (PF). However, the impact of selective PDE10A inhibitors on the tumor growth factor-β (TGF-β)/small mother against decapentaplegic (Smad) signaling pathway remains unclear.

Rapid and comprehensive detection of viral antibodies and nucleic acids via an acoustofluidic integrated molecular diagnostics chip: AIMDx.

Precise and rapid disease detection is critical for controlling infectious diseases like COVID-19. Current technologies struggle to simultaneously identify viral RNAs and host immune antibodies due to limited integration of sample preparation and detection. Here, we present acoustofluidic integrated molecular diagnostics (AIMDx) on a chip, a platform enabling high-speed, sensitive detection of viral immunoglobulins [immunoglobulin A (IgA), IgG, and IgM] and nucleic acids.

Modular Engineering of Lysostaphin with Significantly Improved Stability and Bioavailability for Treating MRSA Infections.

Methicillin-resistant (MRSA) is a refractory pneumonia-causing pathogen due to the antibiotic resistance and the characteristics of persisting inside its host cell. Lysostaphin is a typical bacteriolytic enzyme for degrading bacterial cell walls via hydrolysis of pentaglycine cross-links, showing potential to combat multidrug-resistant bacteria. However, there are still grand challenges for native lysostaphin because of its poor shelf stability and limited bioavailability.

Early Evaluation of the Interaction and Gender Differences in Combination of Apatinib and Metoprolol Using Humanized CYP2D6 Model.

Apatinib, a commonly used tyrosine kinase inhibitor in cancer treatment, can cause adverse reactions such as hypertension. Hypertension, in turn, can increase the risk of certain cancers. The coexistence of these diseases makes the use of combination drugs more common in clinical practice, but the potential interactions and regulatory mechanisms in these drug combinations are poorly understood.

In vitro NIH3T3 mouse embryonic fibroblast cell model does not predict AAV2 or AAVdj-mediated cell transformation.

One of the potential risk factors of recombinant adeno-associated virus (rAAV)-based gene therapy is insertional mutagenesis, which has been associated with the development of hepatocellular carcinoma (HCC) in rAAV-treated neonatal mice. The objective of this study was to investigate if well-established in vitro cell transformation assays (CTA) in mouse cell lines can detect AAV2 or AAVdj-mediated cell transformation. Since AAV integration at the Rian locus in neonatal mice has been implicated in AAV-mediated HCC, an rAAV vector specifically targeting the mouse Rian locus and an additional rAAV vector previously shown to cause HCC in neonatal mice were both tested for the induction of cell transformation in NIH3T3 cells.

Genome-wide identification of UDP-glycosyltransferases involved in flavonol glycosylation induced by UV-B irradiation in Eriobotrya japonica.

Flavonol glycosides are secondary metabolites important for plant development and stress defense such as UV-B irradiation. UDP-glycosyltransferase (UGT) catalyzes the last step in the biosynthesis of flavonol glycosides. Eriobotrya japonica is abundant in flavonol glycosides, but UGTs responsible for accumulation of flavonol glycosides remain unknown.
