WTAP-mediated mA methylation of PHF19 facilitates cell cycle progression by remodeling the accessible chromatin landscape in t(8;21) AML.

Wilms' tumor 1-associated protein (WTAP) is a key N6-methyladenosine (mA) methyltransferase that is upregulated in t(8;21) acute myeloid leukemia (AML) under hypoxia inducible factor 1α-mediated transcriptional activation, promoting leukemogenesis through transcriptome-wide mA modifications. However, the specific substrates and intrinsic regulatory mechanisms of WTAP are not well understood. Here, we provide evidence that PHD finger protein 19 (PHF19) overexpression is regulated by WTAP-mediated mA modification and promotes cell cycle progression by altering chromatin accessibility.

The role of third component in coumarin-based all-small-molecule ternary organic solar cells with non-fullerene acceptor based on molecular stacking.

The power conversion efficiency (PCE) of ternary all-small-molecule organic solar cells (T-ASM-OSCs) differs significantly from that of the polymer systems (2 %), and the role of third component remains unclear. The electron donor of coumarin derivatives with simple structure and strong and broad light absorption has high PCE for T-ASM-OSCs composed of non-fullerene acceptors (Y6 and DBTBT-IC). Here, we calculated the electronic structure and interfacial properties of the binary C1-CN:Y6 and ternary C1-CN:Y6:DBTBT-IC systems using molecular dynamic (MD) simulations and density functional theory (DFT) to explore the role of the third component (DBTBT-IC).

Background: Congenital tracheal stenosis (CTS) is a rare but life-threatening malformation of the trachea. Surgical reconstruction is the treatment of choice in symptomatic cases which is highly risky and is rarely performed in extremely premature infants. With this, reporting a case of CTS managed by tracheal reconstructive surgery under ECMO in a baby weighing 1.

Fusion Modes and Number of Fused Rings: Their Impact on Acceptor-Donor-Acceptor Nonfullerene Acceptors in Organic Solar Cells.

The power conversion efficiency (PCE) of organic solar cells (OSCs) devices has surpassed 19% owing to the blooming of fused-ring nonfullerene acceptors (NFAs), especially for acceptor-donor-acceptor (A-D-A) type NFAs. However, the structural effect of the angular/linear fusion mode and number of fused rings for A-D-A type NFAs on the photovoltaic performance in OSCs devices remains unclear. Herein, the A-D-A type NFAs (, , and ) have been selected to obtain the intrinsic role of structural design strategies including the angular/linear fusion mode and the number of fused rings.

[Mechanism of electroacupuncture at "Zusanli" (ST36) in improving cardiac function in mice with chronic heart failure].

Objectives: To observe the effect of electroacupuncture (EA) at "Zusanli" (ST36) on improving cardiac function in mice with chronic heart failure (CHF), so as to explore the mechanism of its regulation on the autonomic nervous system.

Methods: Eighteen C57BL/6J mice were randomly divided into sham-surgery, model, and EA groups, with 6 mice in each group. The model of myocardial ischemia followed by CHF was induced by ligation of the anterior descending branch of the left coronary artery.

The impact of endogenous N/OFQ on DPN: Insights into lower limb blood flow regulation in rats.

Diabetic peripheral neuropathy (DPN) is a common complication of diabetes, often accompanied by impaired vascular endothelial function in the lower limbs. This dysfunction is characterized by a reduced vasodilatory response, leading to decreased blood flow in the lower limbs and ultimately contributing to the development of diabetic peripheral neuropathy. To delve deeper into this pathological process, the study employed bioinformatics to identify and analyze genes highly active in DPN.

Fluorometric detection and analog discrimination of melatonin by amide naphthotube-based indicator displacement assays.

Melatonin, a hormone synthesized by the pineal gland, is renowned for its pivotal role in governing circadian rhythms and its promising therapeutic attributes encompassing anti-inflammatory, anti-aging, and cancer-preventative properties. Nevertheless, the improper utilization of melatonin may lead to health hazards, highlighting the critical necessity for accurate detection of melatonin in pharmaceutical or biological samples. Furthermore, melatonin metabolites exhibit analogous chemical structures yet divergent pathophysiological functions, emphasizing the significance of distinguishing between these analogs.

Acid-sensing ion channel 1a promotes alcohol-associated liver disease in mice via regulating endoplasmic reticulum autophagy.

Alcohol-associated liver disease (ALD) is a hepatocyte dysfunction disease caused by chronic or excessive alcohol consumption, which can lead to extensive hepatocyte necrosis and even liver failure. Currently, the pathogenesis of ALD and the anti-ALD mechanisms have not been fully elucidated yet. In this study, we investigated the effects of endoplasmic reticulum autophagy (ER-phagy) in ALD and the role of acid-sensing ion channel 1a (ASIC1a) in ER stress-mediated ER-phagy.

Ratiometric fluorescence sensing and discrimination of tetracycline analogs by using coumarin-embedded Eu-MOF nanosensor.

As widely used antibiotics, tetracycline residues exist in food and environmental media, which pose certain hidden dangers and negative effects on public health. Therefore, the sensing and discrimination of tetracycline analogs (TCs) have great significance for improving food safety and preventing environmental pollution. Herein, a 7-hydroxycoumarin-3-carboxylic acid-embedded Eu-MOF (HC@Eu-MOF) material was constructed and then developed for the detection of TCs.

Amide naphthotube as a novel supramolecular sequestration agent for tetracaine and decamethonium.

Rationale: Anesthetics are widely used for optimizing surgical conditions, postoperative pain management, and treating various chronic pain conditions. Tetracaine and decamethonium are representative drugs of local anesthetics and neuromuscular blocking agents, respectively. However, overdose and toxicity of the drugs always lead to serious adverse events.

Acid/base responsive pseudo[3]rotaxanes from amine naphthotubes and bis-pyridinium/isoquinolinium guests.

A novel cooperative pseudo[3]rotaxane system was successfully constructed by the inclusion complexation of two identical amine naphthotubes with a bis-pyridinium/isoquinolinium guest. Single crystal structure analysis revealed that weak C-H⋯O hydrogen bonds between the two hosts are responsible for the positive cooperativity during the formation of pseudo[3]rotaxanes. Moreover, intermolecular charge-transfer interactions between the electron-rich host and the electron-poor guests were observed.

The superiority of isomeric, fluorination and curtailed π-conjunction on A-D-A type acceptors for organic photovoltaics.

The performance of organic solar cell (OSC) devices has been significantly enhanced by the dramatic evolution of A-D-A type non-fullerene acceptors (NFAs). Nevertheless, the structure-property-performance relationship of NFAs in the OSC device is unclear.
