WS Moiré Superlattices Supporting Au Nanoclusters and Isolated Ru to Boost Hydrogen Production.

Maximizing the catalytic activity of single-atom and nanocluster catalysts through the modulation of the interaction between these components and the corresponding supports is crucial but challenging. Herein, guided by theoretical calculations, a nanoporous bilayer WS Moiré superlattices (MSLs) supported Au nanoclusters (NCs) adjacent to Ru single atoms (SAs) (Ru/Au-2LWS) is developed for alkaline hydrogen evolution reaction (HER) for the first time. Theoretical analysis suggests that the induced robust electronic metal-support interaction effect in Ru/Au-2LWS is prone to promote the charge redistribution among Ru SAs, Au NCs, and WS MSLs support, which is beneficial to reduce the energy barrier for water adsorption and thus promoting the subsequent H formation.

Design, synthesis, and biological evaluation of adenosine derivatives targeting DOT1L and HAT as anti-leukemia agents.

Disruptor of telomeric silencing 1-like (DOT1L) is a key hub in histone lysine methyltransferase and an attractive therapeutic target for treating hematological malignancies including acute myeloid leukemia (AML). In this study, we report the design and synthesis of a new series of adenosine derivatives as DOT1L inhibitors by accommodating a basic linker piperidine-4-ylmethyl motif to respective aryl-urea/benzimidazole scaffolds. The anti-DOT1L enzyme activity analysis demonstrated that compounds 8, 12, and 13 strongly suppressed DOT1L activity with IC values ranging from 0.

ctDNA-based molecular residual disease and survival in resectable colorectal cancer.

The interim analysis of the CIRCULATE-Japan GALAXY observational study demonstrated the association of circulating tumor DNA (ctDNA)-based molecular residual disease (MRD) detection with recurrence risk and benefit from adjuvant chemotherapy (ACT) in resectable colorectal cancer (CRC). This updated analysis with a 23-month median follow-up, including 2,240 patients with stage II-III colon cancer or stage IV CRC, reinforces the prognostic value of ctDNA positivity during the MRD window with significantly inferior disease-free survival (DFS; hazard ratio (HR): 11.99, P < 0.

SPHK1 promotes bladder cancer metastasis via PD-L2/c-Src/FAK signaling cascade.

SPHK1 (sphingosine kinase type 1) is characterized as a rate-limiting enzyme in sphingolipid metabolism to phosphorylate sphingosine into sphingosine-1-phosphate (S1P) that can bind to S1P receptors (S1PRs) to initiate several signal transductions leading to cell proliferation and survival of normal cell. Many studies have indicated that SPHK1 is involved in several types of cancer development, however, a little is known in bladder cancer. The TCGA database analysis was utilized for analyzing the clinical relevance of SPHK1 in bladder cancer.

Duckweed-based optical biosensor for herbicide toxicity assessment.

In response to the pervasive issue of herbicide pollution in environmental water bodies, particularly from herbicides used extensively in agriculture, traditional chemical-based water quality analysis methods have proven costly and time-consuming, often failing to meet regulatory standards. To overcome these limitations, global environmental agencies have turned to rapidly-growing species like duckweed as bioindicators for herbicide and pesticide contamination. However, conventional biological assessment methods, such as the 168-h duckweed growth inhibition test, are slow and lack real-time monitoring capabilities.
