CAPE activates AMPK and Foxo3 signaling to induce growth inhibition and ferroptosis in triple-negative breast cancer.

Purpose: Approximately 20% of all breast cancer cases are classified as triple-negative breast cancer (TNBC), which represents the most challenging subtype due to its poor prognosis and high metastatic rate. Caffeic acid phenethyl ester (CAPE), the main component extracted from propolis, has been reported to exhibit anticancer activity across various tumor cell types. This study aimed to investigate the effects and mechanisms of CAPE on TNBC.

Synthesis of Sulfenamides via Photoredox N-S Coupling of Dialkyl Azodicarboxylates and Thiols.

We herein report a photoredox N-S coupling reaction between dialkyl azodicarboxylates and thiols to access sulfenamide scaffolds. This reaction proceeds under mild, green, and operationally simple conditions, offering a broad scope of sulfenamides with high yields and excellent atom efficiency. Mechanistic investigations revealed this reaction followed a photoinitiated radical pathway in which iodide plays a crucial role as both a radical initiator and a single-electron reductant.

The role of KRT18 in lung adenocarcinoma development: integrative bioinformatics and experimental validation.

Lung adenocarcinoma (LUAD) represents one of the most common subtypes of lung cancer with high rates of incidence and mortality, which contributes to substantial health and economic demand across the globe. Treatment today mainly consists of surgery, radiotherapy, and chemotherapy, but their efficacy in advanced stages is often suboptimal and emphasizes the clear need for new biomarkers and therapeutic targets. Using comprehensive bioinformatics analyses consisting of the Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), Human Protein Atlas (HPA) and Clinical Proteomic Tumor Analysis Consortium (CPTAC), immune infiltration analysis and functional enrichment analysis, and single-cell analysis, we examined the potential of keratin 18 (KRT18) as a candidate biomarker in advanced LUAD.

Enhancing Stability and Catalytic Activity of d-Allulose 3-Epimerase through Multistrategy Computational Design and Cross-Regional Advantageous Mutations.

d-Allulose 3-epimerase (DAEase) derived from has excellent properties in the catalytic production of d-allulose, a rare sugar with unique biological functions. However, the industrial application of DAEase (Cb-DAEase) for d-allulose production is hindered by its low enzyme activity, poor long-term thermostability, and pH tolerance. In this study, we identified potential noncatalytic residues in Cb-DAEase using methods such as proline substitution, surface charge engineering, and surface residue prediction.

A Universal Multi-Epitope Vaccine Design Against Porcine Reproductive and Respiratory Syndrome Virus via Bioinformatics and Immunoinformatics Approaches.

Innovative Progress of LSPR-Based Dark-Field Scattering Spectral Imaging in the Biomedical Assay at the Single-Particle Level.

The growing demand for detection and sensing in the biomedical field is placing higher demands on technology. In clinical testing, it is expected to be able to realize both rapid large-field imaging and analysis of single particles (or single molecules or single cells), and it is expected to be able to grasp both the unique individuality of single particles in time and space during the complex reaction process, as well as the regular correlation between single particles in the same population distribution. Supported and promoted by the theory of localized surface plasmon resonance (LSPR), dark-field microscopy, as a single-particle optical imaging technique with a very high signal-to-noise ratio, provides a powerful new means to address the above clinical detection needs.

Effect of COVID-19 infection on thyroid function status and clinical indexes among hypothyroid outpatients.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread rapidly, leading to an Omicron outbreak in Shanghai in mid-December after adjustments to the Coronavirus Disease 2019 (COVID-19) control strategy. To investigate the impact of COVID-19 infection among hypothyroid patients, we gathered data on the hypothyroid outpatients with COVID-19 infection during this time at the Thyroid Disease Center (TDC) of Shanghai Central Hospital. Patients were divided into two groups based on whether their hypothyroidism was caused by Hashimoto's Thyroiditis (HT): the HT and the non-HT group.
