METTL3-mA-mediated TGF-β signaling promotes Fuchs endothelial corneal dystrophy via regulating corneal endothelial-to-mesenchymal transition.

Fuchs endothelial corneal dystrophy (FECD) is the leading cause of vision-threatening corneal endothelial dystrophy without pharmacologic treatments. Corneal endothelial-mesenchymal transition (cEndMT), a specific cellular phenotypic transition, is implicated in the vicious cycle in FECD pathogenesis. Here, we investigated the reversible epigenetic regulation of N-methyladenosine (mA) during cEndMT process and FECD progression.

Hypoxia inducible factor-1α drives cancer resistance to cuproptosis.

Cuproptosis represents a new type of cell death that intricately associated with copper homeostasis and protein lipoylation. The cuproptosis suppression has been characterized in the hypoxic tumor microenvironment (TME). Here we reveal that hypoxia inducible factor-1α (HIF-1α) is a driver of cuproptosis resistance in solid tumor.

Development and validation of a transcription factor regulatory network-based signature for individualized prognostic risk in lung adenocarcinoma.

Despite significant progress in diagnostic and therapeutic modalities, lung adenocarcinoma (LUAD) still exhibits a high recurrence risk and a low 5-year survival rate. Reliable prognostic signatures are imperative for risk stratification in LUAD patients. This study encompassed 2740 patients from 23 LUAD cohorts, including one single-cell RNA sequencing (scRNA-seq) dataset, five bulk RNA-seq datasets, and 17 microarray datasets.

Each subject underwent a comprehensive ophthalmic evaluation, including fundus examination, intraocular pressure assessment, and IVCM imaging.

Massively parallel variant-to-function mapping determines functional regulatory variants of non-small cell lung cancer.

Genome-wide association studies have identified thousands of genetic variants associated with non-small cell lung cancer (NSCLC), however, it is still challenging to determine the causal variants and to improve disease risk prediction. Here, we applied massively parallel reporter assays to perform NSCLC variant-to-function mapping at scale. A total of 1249 candidate variants were evaluated, and 30 potential causal variants within 12 loci were identified.

Lactylation of HDAC1 Confers Resistance to Ferroptosis in Colorectal Cancer.

Colorectal cancer (CRC) is highly resistant to ferroptosis, which hinders the application of anti-ferroptosis therapy. Through drug screening, it is found that histone deacetylase inhibitor (HDACi) significantly sensitized CRC to ferroptosis. The combination of HDACi and ferroptosis inducers synergically suppresses CRC growth both in vivo and in vitro.

The effects of perceived sport environment on sport gains of Chinese university students: chain mediation between physical activity behavior and sport learning self-efficacy.

Introduction: Sports gains reflect the sports development of college students, which is a direct reflection of the quality of school sports work, while the perception of sports environment, physical activity behavior, and self-efficacy in sports learning are closely related to their sports gains, which directly affects their effectiveness and interest in sports learning.

Objective: To investigate the effects of perceived sports environment on Chinese college students' sport gains, and to verify the mediating roles of physical activity behavior and self-efficacy in sport learning.

Methods: A survey of 2,207 Chinese university students was conducted using the sport environment perception scale, sport gain scale, physical activity behavior scale, and sport learning self-efficacy scale.

Targeting CDK2 Confers Vulnerability to Lenvatinib Via Driving Senescence in Anaplastic Thyroid Cancer.

Anaplastic thyroid cancer (ATC) is the most lethal tumor arising from thyroid follicular epithelium. Lenvatinib is an off-label use option for ATC patients in many countries but an approved prescription in Japan. However, lenvatinib resistance is a substantial clinical challenge.

Analysis of the Changes in Volatile Components During the Processing of Enshi Yulu Tea.

Volatile constituents are critical to the flavor of tea, but the changes in Enshi Yulu tea during the processing have not been clearly understood. Using headspace solid phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME/GC-MS) techniques, we analyze the aroma components of Enshi Yulu tea and changes in them during the processing stages. In total, 242 volatile compounds were identified.

Optimal fidelity estimation for density matrix.

Fidelity estimation is a necessary tool for evaluating noise in quantum measurement and quantum computation. The traditional fidelity estimation is to calculate the distance between two density matrices by employing direct fidelity estimation, which consumes too much copies of state. To reduce the number of copies of the state, we develop optimal fidelity estimation by proposing an optimal model.

Exertional heat stroke with pronounced presentation of microangiopathic hemolytic anemia: A case report.

Support from children to parents significantly improves the well-being of older adults, while support from parents to children has less impact.

Unveiling the Hidden Responses: Metagenomic Insights into Dwarf Bamboo () Rhizosphere under Drought and Nitrogen Challenges.

Dwarf bamboo () is a crucial food source for the giant pandas. With its shallow root system and rapid growth, dwarf bamboo is highly sensitive to drought stress and nitrogen deposition, both major concerns of global climate change affecting plant growth and rhizosphere environments. However, few reports address the response mechanisms of the dwarf bamboo rhizosphere environment to these two factors.

LlbHLH87 interacts with LlSPT to modulate thermotolerance via activation of LlHSFA2 and LlEIN3 in lily.

Basic helix-loop-helix (bHLH) proteins comprise one of the largest families of transcription factors in plants, which play roles in plant development, secondary metabolism, and the response to biotic/abiotic stresses. However, the roles of bHLH proteins in thermotolerance are largely unknown.
