PRMT1-mediated metabolic reprogramming promotes leukemogenesis.

Copious expression of protein arginine methyltransferase 1 (PRMT1) is associated with poor survival in many types of cancers, including acute myeloid leukemia. We observed that a specific acute megakaryocytic leukemia (AMKL) cell line (6133) derived from RBM15-MKL1 knock-in mice exhibited heterogeneity in Prmt1 expression levels. Interestingly, only a subpopulation of 6133 cells expressing high levels of Prmt1 caused leukemia when transplanted into congenic mice.

Integrated multi-omics unravels bioactive metabolic networks during red chicory heading.

Red chicory (Cichorium intybus L.) is a leafy vegetable rich in bioactive compounds; however, the metabolic mechanisms underlying its nutritional quality during heading remain poorly understood. A comparison of basic nutritional components across ten inbred lines identified LC018 as exhibiting superior nutrient accumulation.

Single-cell transcriptomic and m6A methylation analyses reveal platelet-mediated immune regulatory mechanisms in sepsis.

Objective: Sepsis is a systemic inflammatory response syndrome triggered by infection, characterized by high clinical heterogeneity and complex immunopathological mechanisms. Immune dysregulation plays a central role in its progression. This study aims to investigate the compositional changes of immune cells, characteristics of intercellular communication, and potential regulatory mechanisms of N⁶-methyladenosine (mA) modification in sepsis, with a particular focus on the functional remodeling of platelets.

Enhanced maturation of mouse immature oocytes using a novel three-dimensional culture system.

The effective utilization of immature oocytes holds promise for improving conception rates in women with low ovarian reserve. The oocyte microenvironment, comprising the extracellular matrix and intercellular communication with somatic cells, is crucial for supporting oocyte maturation. This study hypothesizes that a three-dimensional (3D) culture system, constructed with hydrogels modified by laminin-mimetic peptides-a major component of the extracellular matrix-and granulosa cells (GCs) from mature mouse oocytes, can replicate the biomechanical microenvironment required for oocyte maturation, thereby promoting the development of immature mouse oocytes.

Sodium aescinate protects renal ischemia-reperfusion and pyroptosis through AKT/NLRP3 signaling pathway.

Renal ischemia-reperfusion injury (RIRI) is a common cause of acute renal injury. Studies have shown that sodium aescinate (SA) may serve as a potential therapeutic agent, although its exact mechanism remains unclear. This study first evaluated the efficacy of SA using a mouse renal ischemia-reperfusion model.

Modeling ANKRD26 5'-UTR mutation-related thrombocytopenia.

Mutations in the 5'-untranslated region (5'-UTR) of ankyrin repeat domain-containing protein 26 (ANKRD26) are associated with hereditary thrombocytopenia 2 (THC2). However, the causative role of these mutations and the mechanisms underlying THC2 are not fully established. Here, we report, for the first time, that zebrafish carrying a deletion of two nucleotides (Δ2) in the 5'-UTR of ankrd26 recapitulate some of the key laboratory features of THC2.

Arginine Methylation by PRMT1 Affects ADAMTS13 Secretion and Enzymatic Activity.

Background: ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 repeats, 13), primarily synthesized in hepatic stellate and endothelial cells, plays a pivotal role in regulation of hemostasis by proteolytic cleavage of von Willebrand factor. Severe deficiency of plasma ADAMTS13 activity may result in thrombotic thrombocytopenic purpura, a potentially fatal blood disorder. ADAMTS13 undergoes posttranslational modifications including glycosylation, citrullination, oxidation.

Panax Notoginseng Saponins Inhibit Apoptosis and Alleviate Renal Ischemia-Reperfusion Injury Through the ROCK2/NF-κB Pathway.

Non-invasive prediction of human embryonic ploidy using artificial intelligence: a systematic review and meta-analysis.

Background: Embryonic ploidy is critical for the success of embryo transfer. Currently, preimplantation genetic testing for aneuploidy (PGT-A) is the gold standard for detecting ploidy abnormalities. However, PGT-A has several inherent limitations, including invasive biopsy, high economic burden, and ethical constraints.

Potential antitumor effect of polysaccharides extracted from on human prostate cancer PC‑3 cells.

polysaccharides (PSP) are a traditional herbal medicine component with potential therapeutic effects on several diseases. The present study aimed to assess the role of PSP in the treatment of human prostate cancer using a PC-3 cell line by Cell CK-8, transwell and wound healing assays, then elucidate the potential underlying mechanisms by western blot and quantitative Real-time RT-PCR. Different concentrations of PSP were applied to PC-3 cells, and the proliferation, invasion and migration of PC-3 cells were demonstrated to be significantly inhibited with increasing concentrations of PSP.

We isolated a DHR18 endophytic bacterium from a healthy rubber tree to obtain a new efficient antagonistic bacterium for red root rot disease affecting rubber trees and evaluated the mechanism of action involved using a double culture assay, genome annotation analysis, and the ethyl acetate extraction method.

Coherence sidelobe suppression of laser diode by white-noise-current modulation and external cavity feedback.

A coherence sidelobe suppression method for a laser diode (LD) is proposed, based on the white-noise-current modulation and external cavity feedback. The theoretical model of the coherence of the white-noise-current-modulated external cavity laser (WECL) is established, which details the spectrum broadening mechanism and the coherence sidelobe suppression. At the noise current modulation, the coherence sidelobe induced by the internal cavity is lowered by the external cavity feedback, and the position of the coherence sidelobe induced by the external cavity is controlled with the cavity length, which can extend the coherence range without the sidelobes.

Metabolome and transcriptome integration explored the mechanism of browning in Fisch cells.

Introduction: Fisch, a traditional Chinese medicinal herb known for its diverse pharmacological effects including heat-clearing, detoxification, phlegm dissolving, and cough relief, has experienced an exponential increase in demand due to its expanding clinical use and development prospects.

However, the problem of cell browning represents a significant bottleneck in industrial applications of cell culture.

Microstructures and Rheological Properties of Short-Side-Chain Perfluorosulfonic Acid in Water/2-Propanol.

The viscosity and viscoelasticity of polyelectrolyte solutions with a single electrostatic interaction have been carefully studied experimentally and theoretically.

Background: Long noncoding RNAs (LncRNAs) have been demonstrated to have significant roles in the carcinogenesis of hepatocellular carcinoma (HCC). In this work, we sought to determine LncRNA SH3BP5-AS1's function and mechanism in the emergence of HCC.

Results: First, we discovered that the advanced tumor stage was strongly correlated with high levels of LncRNA SH3BP5-AS1 expression in HCC.

Biocompatible aggregation-induced emission active polyphosphate-manganese nanosheets with glutamine synthetase-like activity in excitotoxic nerve cells.

Glutamine synthetase (GS) is vital in maintaining ammonia and glutamate (Glu) homeostasis in living organisms. However, the natural enzyme relies on adenosine triphosphate (ATP) to activate Glu, resulting in impaired GS function during ATP-deficient neurotoxic events. To date, no reports demonstrate using artificial nanostructures to mimic GS function.
