Chemical Constituents of the Deep-Sea-Derived Penicillium citrinum W22 and Their Ferroptosis Inhibitory Activity.

Chem Biodivers

January 2025

Hainan Pharmaceutical Research and Development Science Park, Hainan Academy of Medical Sciences, Hainan Medical University, Haikou, China.

One new monomeric citrinin analog (1) and 42 known compounds (2-43) were isolated from Penicillium citrinum W22. The structure of 1 was determined by detailed analysis of the 1D and 2D nuclear magnetic resonance (NMR), HRESIMS, and time-dependent density functional theory (TD-DFT)-based electronic circular dichroism (ECD) calculation. Penicitrinol A (2) and methyl 2-(2-acetyl-3,5-dihydroxy-4,6-dimethylphenyl) acetate (11) significantly inhibited renin-angiotensin system-selective lethal 3 (RSL3)-induced ferroptosis with half maximal effective concentration (EC) values of 1.

Department of Cell and Molecular Biology, SciLifeLab, Karolinska Institutet, 171 77 Stockholm, Sweden. Electronic address:

Drugs that target specific proteins often have off-target effects. We present a protocol using artificial neural networks to model cellular transcriptional responses to drugs, aiming to understand their mechanisms of action. We detail steps for predicting transcriptional activities, inferring drug-target interactions, and explaining the off-target mechanism of action.

Institute of Reproductive Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei 430030, P.R. China; NHC Key Laboratory of Birth Defect Prevention, Zhengzhou, Henan 451163, P.R. China. Electronic address:

Quantification of transcription activities in mammalian preimplantation embryos is challenging due to a huge amount of maternally stored transcripts and paucity of research materials. Here, we investigate genome-wide transcription activities of mouse and human preimplantation embryos by quantifying elongating RNA polymerase II. Two transcriptional waves are identified in early mouse embryos, with summits at the 2-cell and 8-cell stages.

Background: Type 2 diabetes (T2D) causes increased health care resource utilization (HCRU) and costs in the United States. People with T2D are more likely to have atherosclerotic cardiovascular disease (ASCVD), which is associated with significant morbidity and mortality. Medical associations recommend cardioprotective antidiabetic medications, including sodium-glucose cotransporter-2 inhibitors (SGLT2is) and glucagon-like peptide 1 receptor agonists (GLP-1 RAs), to reduce the risk of cardiovascular events in patients with T2D with established, or a high risk of, ASCVD, but not all eligible patients receive these medications.

Catalyst design plays a critical role in ensuring sustainable and effective energy conversion. Electrocatalytic materials need to be able to control active sites and introduce defects in both acidic and alkaline electrolytes. Furthermore, producing efficient catalysts with a distinct surface structure advances our comprehension of the mechanism.

Pathogenic variants in HMGCR were recently linked to a limb-girdle muscular dystrophy (LGMD) phenotype. The protein product HMG CoA reductase (HMGCR) catalyzes a key component of the cholesterol synthesis pathway. The two other muscle diseases associated with HMGCR, statin-associated myopathy (SAM) and autoimmune anti-HMGCR myopathy, are not inherited in a Mendelian pattern.

Metal hexacyanoferrates (HCFs), also known as Prussian blue analogues, are ideal cathodes for potassium-ion batteries (PIBs) due to their nontoxicity and cost-effectiveness. Nevertheless, obtaining metal HCF cathode materials with both long-term cycling stability and high rate performance remains a daunting challenge. In this study, we present mesoporous single-crystalline iron hexacyanoferrate (MSC-FeHCF) microspheres, featuring a single-crystalline structure that contains interconnected pores spanning the entire crystal lattice.

Dental resin-based restorative (RBR) materials represent the most ubiquitous biomaterials utilized globally. Methacrylate (MA)-ester based monomers - present in RBRs since the 1960s - experience significantly elevated rates of failure compared to previously used silver/amalgam fillings attributed to their hydrolysis reported in both simulated and in vivo environments. There is currently no alternative RBR chemistry that matches the functional and clinical workflow considerations of MA-RBRs while addressing their limited-service lives.

Understanding the impact of surface copper valence states on the distribution of electrochemical carbon dioxide products is critical. Herein, CuO@Cu2O with a Cu2+/Cu+ interface was fabricated using wet chemical etching approach. The hollow shape offered a large region for gas adsorption, while the interfacial mixed chemical state of Cu2+/Cu+ with tunable control ratio raised the local density of CHO* and accelerated the carbon-carbon coupling reaction.

Background And Objective: Pectus excavatum is a common congenital chest wall abnormality characterized by a concave appearance of the chest, and minimally invasive repair of pectus excavatum (MIRPE) is the surgical treatment of choice. A rapidly growing field of research is pain management in children undergoing MIRPE, with many shifts in practice occurring over the last decade. The primary objectives of this narrative review are to describe current methods of perioperative pain management and the development of enhanced recovery after surgery (ERAS) to improve the experience of patients undergoing MIRPE.

Purpose Of Review: To summarize the current treatment landscape of rheumatoid arthritis-associated interstitial lung disease (RA-ILD) in the context of the recent 2023 American College of Rheumatology/American College of Chest Physicians guideline for ILD treatment in systemic autoimmune rheumatic diseases.

Recent Findings: The guideline conditionally recommends mycophenolate, azathioprine, and rituximab for first-line RA-ILD therapy, with cyclophosphamide and short-term glucocorticoids as additional options. For RA-ILD progression after first line, mycophenolate, rituximab, nintedanib, tocilizumab, cyclophosphamide, and pirfenidone are conditionally recommended, while long-term glucocorticoids are conditionally recommended against.

ABCA1-Super Enhancer RNA Promotes Cholesterol Efflux, Reduces Macrophage-Mediated Inflammation and Atherosclerosis.

JACC Basic Transl Sci

December 2024

Division of Cardiology, Departments of Internal Medicine Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, People's Republic of China.

We describe a previously uncharacterized ATP-binding cassette A1 super enhancer RNA (ABCA1-seRNA)-mediated cholesterol efflux. In addition, it promoted macrophage inflammatory cytokine release, and was causally correlated with coronary artery disease severity. Mechanistically, ABCA1-seRNA upregulated cholesterol efflux by interacting with mediator complex subunit 23 and recruiting retinoid X receptor-alpha and liver X receptor-alpha to promote ABCA1 transcription in a manner.

Neurophotonics

January 2025

Weill Cornell Medicine, Department of Neurological Surgery, New York, United States.

Significance: Despite the availability of various anti-seizure medications, nearly 1/3 of epilepsy patients experience drug-resistant seizures. These patients are left with invasive surgical options that do not guarantee seizure remission. The development of novel treatment options depends on elucidating the complex biology of seizures and brain networks.
