Atorvastatin enhances LDL receptor-mediated LDL-C uptake and modulates PCSK9 protein expression in pancreatic β-cells.

Islets

December 2025

Engineering Research Center of Brain Health Industry of Chinese Medicine, Key Laboratory of Pharmacodynamics and Material Basis of Chinese Medicine of Shaanxi Administration of Traditional Chinese Medicine, Department of Pharmacology, Shaanxi University of Chinese Medicine, Xianyang, China.

Statins are widely used to treat hyperlipidemia and atherosclerotic cardiovascular diseases (ACVD) by significantly lowering low-density lipoprotein cholesterol (LDL-C) levels. However, their use has been associated with an increased risk of type 2 diabetes (T2D), a paradox given their lipid-lowering benefits. This study investigates the role of LDL receptors (LDLR) and proprotein convertase subtilisin/kexin type 9 (PCSK9) in the diabetogenic effects of atorvastatin on pancreatic β-cells.

G protein-coupled receptor, class C, group 5, member D (GPRC5D) has emerged as a novel target for chimeric antigen receptor (CAR) T-cell therapy, demonstrating promising efficacy in multiple myeloma (MM). However, disease relapse is still common, and the mechanism of resistance remains poorly understood. In this study, we conducted whole-genome sequencing (WGS) and whole-genome bisulfite sequencing (WGBS) on MM samples from 10 patients who relapsed after GPRC5D CAR T-cell therapy.

The Csa blood group antigen was identified more than 50 years ago but its genetic basis has yet to be elucidated. All our recent genomic investigation has failed to resolve the genetic basis of this enigmatic antigen. By investigating the association of the HNA-3a/b polymorphism (rs2288904-G/A) in SLC44A2 with clinical features of Sickle Cell Disease (SCD), we incidentally discovered that rare subjects with the homozygous HNA-3b/b genotype also carry the uncommon Cs(a-) phenotype.

Hemophagocytic lymphohistiocytosis (HLH) is a severe hyperinflammatory syndrome, and the overall survival of adult patients is poor. Ruxolitinib, a Janus kinase (JAK) 1/2 inhibitor, has shown promise in treating HLH and exerts synergistic effects when combined with dexamethasone. Our pilot study preliminarily demonstrated that the combination of ruxolitinib and dexamethasone (the Ru-D regimen) had a high response rate and led to favorable short-term survival outcomes in adult HLH patients.

The critical role of leukemic initiating cells as a therapy-resistant population in myeloid leukemia is well established, however, the molecular signatures of such cells in acute lymphoblastic leukemia remain underexplored. Moreover, their role in therapy response and patient prognosis is yet to be systematically investigated across various types of acute leukemia. We employed single-cell multiomics to analyze diagnostic specimens from 96 pediatric patients with acute lymphoblastic, myeloid, and lineage ambiguous leukemias.

Background: Magnetic resonance-guided adaptive radiation therapy (MRgART) systems combine Magnetic resonance imaging (MRI) technology with linear accelerators (LINAC) to enhance the precision and efficacy of cancer treatment. These systems enable real-time adjustments of treatment plans based on the latest patient anatomy, creating an urgent need for accurate and rapid dose calculation algorithms. Traditional CT-based dose calculations and ray-tracing (RT) processes are time-consuming and may not be feasible for the online adaptive workflow required in MRgART.

Global food production faces persistent threats from environmental challenges and pathogenic attacks, leading to significant yield losses. Conventional strategies to combat pathogens, such as fungicides and disease-resistant breeding, are limited by environmental contamination and emergence of pathogen resistance. Herein, we engineered sunlight-sensitive and biodegradable carbon dots (CDs) capable of generating reactive oxygen species (ROS), offering a novel and sustainable approach for plant protection.

Background: Quantitative susceptibility mapping (QSM) is a post-processing magnetic resonance imaging (MRI) technique that extracts the distribution of tissue susceptibilities and holds significant promise in the study of neurological diseases. However, the ill-conditioned nature of dipole inversion often results in noise and artifacts during QSM reconstruction from the tissue field. Deep learning methods have shown great potential in addressing these issues; however, most existing approaches rely on basic U-net structures, leading to limited performances and reconstruction artifacts sometimes.

Background: Accurate segmentation of lesions is beneficial for quantitative analysis and precision medicine in multimodal magnetic resonance imaging (MRI).

Purpose: Currently, multimodal MRI fusion segmentation networks still face two main issues. On one hand, simple feature concatenation fails to fully capture the complex relationships between different modalities, as it overlooks the importance of dynamically changing feature weights across modalities.

Sepsis-associated acute kidney injury (AKI) poses a severe threat to patients' lives and health, making early predictions, intervention, and treatment crucial. This study aims to preliminarily explore the clinical role of miR-577 and miR-494-3p in sepsis-associated AKI. The study included 70 sepsis patients with AKI, 65 sepsis patients without AKI, and a healthy control group (HC, n = 67) to set baseline miRNA levels.

Background: Recently, deep convolutional neural networks (CNNs) have shown great potential in medical image classification tasks. However, the practical usage of the methods is constrained by two challenges: 1) the challenge of using nonindependent and identically distributed (non-IID) datasets from various medical institutions while ensuring privacy, and 2) the data imbalance problem due to the frequency of different diseases.

Purpose: The objective of this paper is to present a novel approach for addressing these challenges through a decentralized learning method using a prototypical contrastive network to achieve precise medical image classification while mitigating the non-IID problem across different clients.

In previous studies, we discovered YZD-7082B, a selective estrogen receptor degrader (SERD) with excellent comprehensive properties. Here, we reported the development of an efficient multigram-scale synthetic process for YZD-7082 in 13 steps. The route featured a chiral resolution of a thiochroman intermediate with a unique cis-1,2-diaryl motif using a chiral amine and a mild reduction of amide using ZnEt/LiCl/(EtO)SiH system.

Neuropathic pain, often featuring allodynia, imposes significant physical and psychological burdens on patients, with limited treatments due to unclear central mechanisms. Addressing this challenge remains a crucial unsolved issue in pain medicine. Our previous study, using protein kinase C gamma (PKCγ)-tdTomato mice, highlights the spinal feedforward inhibitory circuit involving PKCγ neurons in gating neuropathic allodynia.

Purpose: Existing prognostic staging systems depend on expensive manual extraction by pathologists, potentially overlooking latent patterns critical for prognosis, or use black-box deep learning models, limiting clinical acceptance. This study introduces a novel deep learning-assisted paradigm that complements existing approaches by generating interpretable, multi-view risk scores to stratify prognostic risk in hepatocellular carcinoma (HCC) patients.

Methods: 510 HCC patients were enrolled in an internal dataset (SYSUCC) as training and validation cohorts to develop the Hybrid Deep Score (HDS).

Organophosphate pesticides (OPs) are widely used in agricultural fields and can inhibit the activity of human acetylcholinesterase (hAChE) by covalently binding to serine at the enzyme's active site. However, the molecular recognition mechanisms beyond their covalent binding remain unclear. This study employed molecular docking along with molecular dynamics simulations (MD) to investigate four representative OPs, Phosphamidon, Monocrotophos, Dichlorvos, and Trichlorfon, as well as two potential alternatives Magnolol (MAG) and Honokiol (HON), to understand the conformational change of hAChE and its molecular recognition mechanism.
