Discovery of 1,3,4-oxadiazin-5-one Derivative CJ1-34 as a Partial ATP Synthase Inhibitor for CNS Applications.

ATP synthase dysregulation has been implicated in many diseases, including cancer and neurodegenerative diseases. Whilst ATP synthase-targeting compounds have been reported, most are large or polar compounds and lack appropriate properties for a CNS drug. We designed, synthesised, and evaluated a novel series of ATP synthase targeting compounds, resulting in a 1,3,4-oxadiazin-5-one scaffold with improved physiochemical properties.

Antibody ligation of HLA class II induces YAP nuclear localization and formation of cytoplasmic YAP condensates in human endothelial cells.

Antibody (Ab) crosslinking of HLA class II (HLA II) molecules on the surface of endothelial cells (ECs) triggers proliferative and prosurvival intracellular signaling, which are implicated in promoting chronic Ab-mediated rejection (cAMR). Despite the importance of cAMR in transplant medicine, the mechanisms involved remain incompletely understood. Here, we examined the regulation of yes-associated protein (YAP) nuclear cytoplasmic localization and phosphorylation in human ECs challenged with Abs that bind HLA II, which are strongly associated with cAMR.

The impact of cytokines and tumour-conditioned medium on the properties of murine in vitro generated myeloid-derived suppressor cells.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immature myeloid cells playing a critical role in immune suppression. In vitro-generated MDSCs are a convenient tool to study the properties of tumour-associated MDSCs. Here, we compared six protocols for in vitro generation of functional mouse MDSCs from bone marrow progenitors.

Neural-WDRC: A Deep Learning Wide Dynamic Range Compression Method Combined With Controllable Noise Reduction for Hearing Aids.

Wide dynamic range compression (WDRC) and noise reduction both play important roles in hearing aids. WDRC provides level-dependent amplification so that the level of sound produced by the hearing aid falls between the hearing threshold and the highest comfortable level of the listener, while noise reduction reduces ambient noise with the goal of improving intelligibility and listening comfort and reducing effort. In most current hearing aids, noise reduction and WDRC are implemented sequentially, but this may lead to distortion of the amplitude modulation patterns of both the speech and the noise.

Involvement of metformin and aging in salivary expression of ACE2 and TMPRSS2.

SARS-CoV-2-related proteins, ACE2 and TMPRSS2, are determinants of SARS-CoV-2 infection. Although these proteins are expressed in oral-related tissues, their expression patterns and modulatory mechanisms in the salivary glands remain unknown. We herein showed that full-length ACE2, which has both a fully functional enzyme catalytic site and high-affinity SARS-CoV-2 spike S1-binding sites, was more highly expressed in salivary glands than in oral mucosal epithelial cells and the lungs.

Transcriptomic Profiling Reveals 17β-Estradiol Treatment Represses Ubiquitin-Proteasomal Mediators in Skeletal Muscle of Ovariectomized Mice.

Background: With a decline of 17β-estradiol (E2) at menopause, E2 has been implicated in the accompanied loss of skeletal muscle mass and strength. We aimed at characterizing transcriptomic responses of skeletal muscle to E2 in female mice, testing the hypothesis that genes and pathways related to contraction and maintenance of mass are differentially expressed in ovariectomized mice with and without E2 treatment.

Methods: Soleus and tibialis anterior (TA) muscles from C57BL/6 ovariectomized mice treated with placebo (OVX) or E2 (OVX + E2) for 60 days, or from skeletal muscle-specific ERα knockout (skmERαKO) mice and wild-type littermates (skmERαWT), were used for genome-wide expression profiling, quantitative real-time PCR and immunoblotting.

Gene-Air Pollution Interaction and Diversity of Genetic Sampling: The Southern California Children's Health Study.

Gene-environment interactions have been observed for childhood asthma, however few have been assessed in ethnically diverse populations. Thus, we examined how polygenic risk score (PRS) modifies the association between ambient air pollution exposure (nitrogen dioxide [NO], ozone, particulate matter < 2.5 and < 10 μm) and childhood asthma incidence in a diverse cohort.

FDA-approved drugs featuring macrocycles or medium-sized rings.

Macrocycles or medium-sized rings offer diverse functionality and stereochemical complexity in a well-organized ring structure, allowing them to fulfill various biochemical functions, resulting in high affinity and selectivity for protein targets, while preserving sufficient bioavailability to reach intracellular compartments. These features have made macrocycles attractive candidates in organic synthesis and drug discovery. Since the 20th century, more than three-score macrocyclic drugs, including radiopharmaceuticals, have been approved by the US Food and Drug Administration (FDA) for treating bacterial and viral infections, cancer, obesity, immunosuppression, inflammatory, and neurological disorders, managing cardiovascular diseases, diabetes, and more.

Immunomodulation effects of collagen hydrogel encapsulating extracellular vesicles derived from calcium silicate stimulated-adipose mesenchymal stem cells for diabetic healing.

Diabetic wounds are characterized by chronic inflammation, reduced angiogenesis, and insufficient collagen deposition, leading to impaired healing. Extracellular vesicles (EVs) derived from adipose-derived mesenchymal stem cells (ADSC) offer a promising cell-free therapeutic strategy, yet their efficacy and immunomodulation can be enhanced through bioactivation. In this study, we developed calcium silicate (CS)-stimulated ADSC-derived EVs (CSEV) incorporated into collagen hydrogels to create a sustained-release system for promoting diabetic wound healing.
