WTAP-Mediated m6A Modification of TRAIL-DR4 Suppresses MH7A Cell Apoptosis.

Background: N6-methyladenosine (m6A) is one of the most conserved internal RNA modifications, which has been implicated in many biological processes, such as apoptosis and proliferation. Wilms tumor 1-associating protein (WTAP), as a key component of m6A methylation, is a nuclear protein that has been associated with the regulation of proliferation and apoptosis. Rheumatoid arthritis (RA), a systemic, infiltrating autoimmune disease, is characterized by synovial hyperplasia.

MOF-Derived Nitrogen-Rich Hollow Nanocages as a Sulfur Carrier for High-Voltage Aluminum Sulfur Batteries.

Aluminum-sulfur batteries (ASBs) are emerging as promising energy storage systems due to their safety, low cost, and high theoretical capacity. However, it remains a challenge to overcome voltage hysteresis and short cycle life in the sulfur/AlS conversion reaction, which hinders the development of ASBs. Here, we studied a high-voltage ASB system based on sulfur oxidation in an AlCl/urea electrolyte.

Chiral coordination polymer nanowires boost radiation-induced in situ tumor vaccination.

Radiation-induced in situ tumor vaccination alone is very weak and insufficient to elicit robust antitumor immune responses. In this work, we address this issue by developing chiral vidarabine monophosphate-gadolinium nanowires (aAGd-NWs) through coordination-driven self-assembly. We elucidate the mechanism of aAGd-NW assembly and characterize their distinct features, which include a negative surface charge, ultrafine topography, and right-handed chirality.

Ultrafast micro/nano-manufacturing of metastable materials for energy.

In this review, we provide an overview of various metastable micro- and nanomaterials synthesized via HTS, including single metallic and bimetallic nanostructures, high entropy alloys, metal compounds (e.

Cascade Dual Sites Modulate Local CO Coverage and Hydrogen-Binding Strength to Boost CO Electroreduction to Ethylene.

Rationally modulating the binding strength of reaction intermediates on surface sites of copper-based catalysts could facilitate C-C coupling to generate multicarbon products in an electrochemical CO reduction reaction. Herein, theoretical calculations reveal that cascade Ag-Cu dual sites could synergistically increase local CO coverage and lower the kinetic barrier for CO protonation, leading to enhanced asymmetric C-C coupling to generate CH. As a proof of concept, the CuN-Ag nanocubes (NCs) with Ag located in partial Cu sites and a CuN unit center are successfully synthesized.

Therefore, the timely detection of this condition is of utmost importance. Blood culture is considered the gold standard for diagnosing BSIs.

Resveratrol attenuates efavirenz-induced hepatic steatosis and hypercholesterolemia in mice by inhibiting pregnane X receptor activation and decreasing inflammation.

Efavirenz (EFV), a widely prescribed antiviral medication, has been implicated in dyslipidemia and can activate the pregnane X receptor (PXR), leading to hepatic steatosis and hypercholesterolemia in mice. Resveratrol (RES) can ameliorate hepatic steatosis and functions as a partial PXR agonist, capable of mitigating PXR expression induced by other PXR agonists. Therefore, we hypothesized that RES could attenuate EFV-induced hepatic steatosis and hypercholesterolemia by downregulating PXR expression and suppressing inflammatory cytokine production.

With the development of cryo-electron microscopy (cryo-EM), high-resolution structures of macromolecules can be reconstructed by the single particle method efficiently. However, challenges may still persist during the specimen preparation stage. Specifically, proteins tend to adsorb at the air-water interface and exhibit a preferred orientation in vitreous ice.

Network pharmacology approach and molecular docking to explore the potential mechanism of Wu-Wei-Wen-Tong Chubi capsules in rheumatoid arthritis.

Network pharmacology, a holistic approach based on the theory of biological network technology, integrates information from biological systems, drugs, and diseases. Here, this theory was used to predict the targets of Wu-Wei-Wen-Tong Chubi capsule (WWWT) to explore the mechanism in the treatment of rheumatoid arthritis (RA). The ingredients of each herbal medicine in WWWT were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and the active ingredients were screened through bioavailability (OB) ≥30% and drug-likeness (DL) ≥ 0.

Disseminated talaromycosis complicated by recurrent gastrointestinal bleeding and hemorrhagic shock: a case report.

The abnormal distribution of NK cell subsets before HAART treatment may be related to the level of immune reconstitution in HIV patient.

Background: HIV infection leads to the damage of NK cells, which is closely associated with the disease's progression, but whether it affects immune reconstitution after Highly Active Antiretroviral Therapy (HAART) is not clear.

Methods: From March 9 to October 31, 2017, a total of 75 confirmed cases with HIV in Wenzhou were collected and analyzed. NK cell subsets were measured and compared among three groups: the control group, the group whose CD4 T cell counts <200/μL (named as low-CD4 group) and the group whose CD4 T cell counts ≥200/μL (named as high-CD4 group).

Astragaloside regulates lncRNA LOC100912373 and the miR‑17‑5p/PDK1 axis to inhibit the proliferation of fibroblast‑like synoviocytes in rats with rheumatoid arthritis.

Previous studies have confirmed that astragaloside (AST) exerts a positive effect on alleviating synovial and joint injury in rheumatoid arthritis (RA). However, the precise mechanisms through which AST acts in the treatment of RA remain unclear. Long non‑coding RNA (lncRNA) LOC100912373 was identified as a key gene related to RA and has been proven to interact with miR‑17‑5p, in order to regulate the pyruvate dehydrogenase kinase 1 and protein kinase B axis (PDK1/AKT axis).

Evoking ordered vacancies in metallic nanostructures toward a vacated Barlow packing for high-performance hydrogen evolution.

Metallic nanostructures are commonly densely packed into a few packing variants with slightly different atomic packing factors. The structural aspects and physicochemical properties related with the vacancies in such nanostructures are rarely explored because of lack of an effective way to control the introduction of vacancy sites. Highly voided metallic nanostructures with ordered vacancies are however energetically high lying and very difficult to synthesize.

Transcriptome-Wide High-Throughput m6A Sequencing of Differential m6A Methylation Patterns in the Human Rheumatoid Arthritis Fibroblast-Like Synoviocytes Cell Line MH7A.

Introduction: N6-methyladenosine (m6A) is the most frequent internal modification in eukaryotic mRNAs and is closely related to the occurrence and development of many diseases, especially tumors. However, the relationship between m6A methylation and rheumatoid arthritis (RA) is still a mystery.

Methods: Two high-throughput sequencing methods, namely, m6A modified RNA immunoprecipitation sequence (m6A-seq) and RNA sequence (RNA-seq) were performed to identify the differentially expressed m6A methylation in human rheumatoid arthritis fibroblast-like synoviocytes cell line MH7A after stimulation with TNF-α.

LncRNA LOC100912373 modulates PDK1 expression by sponging miR-17-5p to promote the proliferation of fibroblast-like synoviocytes in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a common autoimmune disease and characterized by chronic inflammation, abnormal synovial cell proliferation, and joint swelling and tenderness, and it causes patients substantial pain. To date, the pathogenesis of RA remains unclear, and specific treatment is still lacking in the clinic. Evidence from previous research indicated that the long noncoding RNA (lncRNA) LOC100912373 is a key lncRNA and involved in RA.
