Accurate and reliable quantification of disease-related biomolecules is essential for clinical diagnosis. In this study, a novel electrochemical approach is developed based on a target triggered DNA nanostructural switch from a hairpin dimer to a double-stranded wheel. During the process, electrochemical species get closer to the electrode interface, and the multiple intramolecular strand displacements are beneficial to low abundant target analysis.

Introduction: In the environment, mycotoxins and fungicides frequently coexist, potentially causing synergistic risks to organisms. Epoxiconazole (EPO) and aflatoxin B1 (AFB1) are a common fungicide and mycotoxins, respectively, which are widely present in the environment and have toxic effects on multiple organs once entering the organism, but it is still unclear whether the co-exposure has a synergistic toxic effect.

Objectives: This study delves into the molecular mechanisms underlying the co-exposure to EPO and AFB1, emphasizing multi-organ toxicity in female zebrafish (F0 generation) and potential transgenerational impacts on the offspring embryos (F1 generation) through multi-omics approaches.

The optimal breast cancer (BC) screening age in China remains uncertain. In this study, we evaluated the benefits, harms, and cost-effectiveness of lowering the screening starting age from 45 to 35 years and extending the stopping age from 64 to 79 years in Chinese women at an average risk of progressing BC. Biennial screening showed a lower incremental cost-effectiveness ratio (ICER) compared to annual screening.

Electronic address:

U2AF1 is a core component of spliceosome and controls cell-fate specific alternative splicing. U2AF1 mutations have been frequently identified in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) patients, and mutations in U2AF1 are associated with poor prognosis in hematopoietic malignant diseases. Here, by forced expression of mutant U2AF1 (U2AF1 S34F) in hematopoietic and leukemic cell lines, we find that U2AF1 S34F causes increased reactive oxygen species (ROS) production.

Methods: In the study, 591 patients with distal or middle-third, clinical primary tumor stage cT3-4 and/or regional lymph node-positive rectal cancer were randomly assigned (1:1) to receive short-term radiotherapy (25 Gy in five fractions) followed by 4 cycles of CAPOX (TNT group, n=297) or standard concurrent chemoradiotherapy (50 Gy in 25 fractions concurrently with oral capecitabine) (CRT group, n=294) before surgery. After a 6-year follow-up, the surviving patients were sent surveys, including the EORTC QLQ-C30, EORTC QLQ-CR29, and Wexner incontinence score questionnaires.

Electronic address:

Bacterial infection reprograms cellular metabolism and epigenetic status, but how the metabolic-epigenetic crosstalk empowers host antibacterial defense remains unclear. Here, we report that heterogeneous nuclear ribonucleoprotein A2B1 (hnRNPA2B1) is a sensor for metabolite adenine to launch an antimicrobial innate response through increasing Il1b transcription. Myeloid cell-specific Hnrnpa2b1-cKO mice are more susceptible to bacterial infection, while interleukin 1 beta (IL-1β) supplementation rescues the phenotype.

PSEN1 E280A carrier for the APOE3 Christchurch variant (R136S) is protected against Alzheimer's disease (AD) symptoms with a distinct anatomical pattern of Tau pathology. However, the molecular mechanism accounting for this protective effect remains incompletely understood. Here, we show that the ApoE3 R136S mutant strongly binds to Tau and reduces its uptake into neurons and microglia compared with ApoE3 wild type (WT), diminishing Tau fragmentation by asparagine endopeptidase (AEP), proinflammatory cytokines by Tau pre-formed fibrils (PFFs) or β-amyloid (Aβ), and neurotoxicity.

The ER protein CANX (calnexin)-mediated autophagy protects against alzheimer disease.

Autophagy

January 2025

Guangdong Key Laboratory of Age-Related Cardiac and Cerebral Diseases, Department of Neurology, Affiliated Hospital of Guangdong Medical University, Zhanjiang, China.

Although the relationship between macroautophagy/autophagy and Alzheimer disease (AD) is widely studied, the underlying mechanisms are poorly understood, especially the regulatory role of the initiation signaling of autophagy on AD. Here, we find that the ER transmembrane protein CANX (calnexin) is a novel interaction partner of the autophagy-inducing kinase ULK1 and is required for ULK1 recruitment to the ER under basal or starved conditions. Loss of CANX results in the inactivity of ULK1 kinase and inhibits autophagy flux.

Macrophage-specific in vivo RNA editing promotes phagocytosis and antitumor immunity in mice.

College of Pharmaceutical Sciences, State Key Laboratory of Advanced Drug Delivery and Release Systems, Zhejiang University, Hangzhou 310058, China.

Macrophages play a central role in antitumor immunity, making them an attractive target for gene therapy strategies. However, macrophages are difficult to transfect because of nucleic acid sensors that can trigger the degradation of foreign plasmid DNA. Here, we developed a macrophage-specific editing (MAGE) system by which compact plasmid DNA encoding a CasRx editor can be delivered to macrophages by a poly(β-amino ester) (PBAE) carrier to bypass the DNA sensor and enable RNA editing in vitro and in vivo.
