Subtype-specific HER3 enrichment in basal-like breast cancer is regulated via the GATA2/GATA3-FOXA1 axis.

Basal-like breast cancer (BLBC) is a major subtype of triple-negative breast cancer (TNBC), characterized by aggressive behavior, limited treatment options, and poor prognosis. While HER3 overexpression is frequently observed in TNBC and associated with poor outcomes, its subtype-specific expression and therapeutic potential remain unclear. Here, we demonstrated that HER3 signaling is selectively hyperactivated in BLBC compared to claudin-low breast cancer (CLBC) using transcriptomic profiling.

Phylogenetically and metabolically diverse active carbon-fixing microbes reside in mangrove sediments.

Background: Mangroves are hotspots of carbon sequestration in transitional zones between marine and terrestrial ecosystems. Microbially driven dark carbon fixation (DCF) is prominent in sediments, yet our understanding of the DCF process across this continuum remains limited. In this study, we explored DCF activities and associated chemoautotrophs along the sediment depth of different mangrove sites in Fujian Province, China, using radiocarbon labeling and molecular techniques.

The relationship between prenatal perfluorine and polyfluoroalkyl substances (PFAS) exposure and infant neurodevelopment: Modifying effects of DHA revised.

Background: It has been found that prenatal perfluorine and polyfluoroalkyl substances (PFAS) exposure can affect infant neurodevelopment. On the other hand, docosahexaenoic acid (DHA) supplementation can improve neurodevelopment, but studies on whether it can improve neurodevelopmental delay caused by prenatal PFAS exposure are limited.

Objective: This study aimed to investigate the relationship between prenatal PFAS exposure and infant neurodevelopmental delay and evaluate the effects of postnatal DHA supplementation on infant neurodevelopment.

Strong heterogeneity in laterally exchanged particulate organic matter across tidal marshes in a large river delta.

Understanding the lateral exchange of particulate organic matter (POM) between wetlands and estuaries is essential for understanding coastal carbon budgets and dynamics. We studied tidal and seasonal changes in the concentration of POM ([POC]) and its optical properties in three marsh creek systems along a salinity gradient in one of the world's largest river deltas - the Yangtze River Delta. Results reveal strong variability, with tides and among sites, in both [POC] and compositions of POM.

Enhancing the synthesis efficiency of galacto-oligosaccharides of a β-galactosidase from Paenibacillus barengoltzii by engineering the active and distal sites.

Previously, a glycoside hydrolase (GH) family 2 β-galactosidase (PbBGal2A) from Paenibacillus barengoltzii is characterized for its high transglycosylation capability. Here, the cryo-electron microscopy (cryo-EM) structure of PbBGal2A was determined, revealing an enlarged acidic catalytic pocket that facilitate the binding of carbohydrate substrates. Three structure-based strategies as well as machine learning MECE platform (method for enhancing the catalytic efficiency) were employed to identify active and distal mutations with enhanced galacto-oligosaccharides (GOS) synthesis and their synergistic effects were evaluated.

[Rapid and simultaneous determination of 11 ergot alkaloids in cereals and their products by ultra performance liquid chromatography-tandem mass spectrometry combined with Captiva EMR-Lipid column purification].

Ergot alkaloids (EAs) are mycotoxins produced by and are present in cereals and their products; their residues pose significant threats to human health through food consumption, resulting in ergotism and sickness. Herein, a sensitive and rapid method for the determination of 11 EAs in cereals and their products using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) were developed. Eleven EAs were extracted with 20 mL acetonitrile-200 mg/L ammonium acetate solution (80∶20, v/v) for 15 min using the vortex shock method followed by 15 min of ultrasonication.

HemaCisDB: An Interactive Database for Analyzing Cis-regulatory Elements Across Hematopoietic Malignancies.

Non-coding cis-regulatory elements (CREs), such as transcriptional enhancers, are key regulators of gene expression programs. Accessible chromatin and H3K27ac are well-recognized markers for CREs associated with their biological function. Deregulation of CREs is commonly found in hematopoietic malignancies, yet the extent to which CRE dysfunction contributes to pathophysiology remains incompletely understood.

Construction of a Novel Vanillin-Induced Autoregulating Bidirectional Transport System in a Vanillin-Producing Cell Factory.

Vanillin is one of the world's most extensively used flavoring agents with high application value. However, the yield of vanillin biosynthesis remains limited due to the low efficiency of substrate uptake and the inhibitory effect on cell growth caused by vanillin. Here, we screened high-efficiency ferulic acid importer TodX and vanillin exporters PP_0178 and PP_0179 by overexpressing genes encoding candidate transporters in a vanillin-producing engineered strain VA and further constructed an autoregulatory bidirectional transport system by coexpressing TodX and PP_0178/PP_0179 with a vanillin self-inducible promoter .

Fish oil-loaded multicore submillimeter-sized capsules prepared with monoaxial electrospraying, chitosan-tripolyphosphate ionotropic gelation, and Tween blending.

In order to load fish oil for potential encapsulation of fat-soluble functional active substances, fish oil-loaded multicore submillimeter-sized capsules were prepared with a combination method of three strategies (monoaxial electrospraying, chitosan-tripolyphosphate ionotropic gelation, and Tween blending). The chitosan-tripolyphosphate/Tween (20, 40, 60, and 80) capsules had smaller and evener fish oil cores than the chitosan-tripolyphosphate capsules, which resulted from that Tween addition induced smaller and evener fish oil droplets in the emulsions. Tween addition decreased the water contents from 56.

Using gas chromatography-tandem mass spectrometry and electrospun nanofibrous membrane, we developed and validated a simple, rapid, and sensitive methodology for quantifying eugenol residues in fish tissue and water samples. Fish tissue extract and water samples (315 samples) collected from three southeastern China provinces (Shanghai, Zhejiang, and Fujian), originating from eight provinces of Zhejiang, Jiangsu, Shandong, Guangdong, Fujian, Anhui, Shanghai, and Jiangxi, from April 2021 to April 2023 were filtered with an electrospun nanofiber membrane, extracted with trichloromethane/-hexane, and directly concentrated to dry after simple purification. An internal standard of -terphenyl in -hexane and 5-µL injection volumes of the solutions was used to analyze eugenol via internal calibration with a minimum concentration of 0.

Active dark carbon fixation evidenced by C isotope assimilation and metagenomic data across the estuarine-coastal continuum.

This study explored DCF activities and associated chemoautotrophs along the estuarine and coastal environmental gradients, using radiocarbon labelling and molecular techniques. Significantly higher DCF rates were observed at middle- and high-salinity regions (0.

Coastal wetlands are hotspots for methane (CH) production, reducing their potential for global warming mitigation. Nitrite/nitrate-dependent anaerobic methane oxidation (n-DAMO) plays a crucial role in bridging carbon and nitrogen cycles, contributing significantly to CH consumption. However, the role of n-DAMO in reducing CH emissions in coastal wetlands is poorly understood.
