Netrin-1 (NTN1) is a laminin-related secreted protein involved in axon guidance and cell migration. Previous research has established a significant connection between NTN1 and nervous system development. In recent years, mounting evidence indicates that NTN1 also plays a crucial role in tumorigenesis and tumor progression.

Functional nanoplatform for modulating cellular forces to enhance antitumor immunity via mechanotransduction.

J Control Release

January 2025

Medical 3D Printing Center, The First Affiliated Hospital of Zhengzhou University, Zhengzhou University, Zhengzhou 450000, China. Electronic address:

Immune cells are sensitive to the perception of mechanical stimuli in the tumor microenvironment. Changes in biophysical cues within tumor tissue can alter the force-sensing mechanisms experienced by cells. Mechanical stimuli within the extracellular matrix are transformed into biochemical signals through mechanotransduction.

Melanocortin 5 receptor signaling protects against podocyte injury in proteinuric glomerulopathies.

Kidney Int

January 2025

Division of Nephrology, Department of Medicine, University of Toledo College of Medicine, Toledo, Ohio, USA; Division of Kidney Disease and Hypertension, Rhode Island Hospital, the Warren Alpert Medical School of Brown University, Providence, Rhode Island, USA. Electronic address:

Melanocortin therapeutics, exemplified by adrenocorticotropic hormone, have a proven steroidogenic-independent anti-proteinuric and glomerular protective effect. The biological functions of melanocortins are mediated by melanocortin receptors (MCR), including MC1R, which recent studies have shown to protect against glomerular disease. However, the role of other MCRs like MC5R is unknown.

3,4-Methylenedioxymethamphetamine (MDMA) is a widely recognized entactogen frequently used recreationally. It is known for its interaction with the serotonin and oxytocin systems, which underlie its entactogenic effects in humans. Recently, we demonstrated that the gut-brain axis, mediated by the subdiaphragmatic vagus nerve, contributes to MDMA-induced resilience enhancement in rodents.

Intrauterine adhesion (IUA) is an endometrial damage repair disorder that leads to menstrual loss, amenorrhea, and infertility in women; therefore, addressing this dilemma is a critical challenge. In this study, a multifunctional hydrogel, comprising oxidized sodium alginate (OSA), strontium carbonate (SrCO), and betamethasone 21-phosphate sodium (BSP), was formulated to facilitate angiogenesis, reduce fibrosis, and support tissue repair in the treatment of IUA. The composite hydrogels showed significant bioactivity on human endometrial stromal cells (HESCs) and human umbilical vein endothelial cells (HUVECs), promoting the injured HESCs repair, reversing the degree of fibrosis to a certain extent, and enhancing the proliferation and migration of HUVECs.

Liver ischemia-reperfusion (IR) injury is a common complication following liver surgery, significantly impacting the prognosis of liver transplantation and other liver surgeries. Betaine-homocysteine methyltransferase (BHMT), a crucial enzyme in the methionine cycle, has been previously confirmed the pivotal role in hepatocellular carcinoma, and it has also been demonstrated that BHMT inhibits inflammation, apoptosis, but its role in liver IR injury remains unknow. Following I/R injury, we found that BHMT expression was significantly upregulated in human liver transplant specimens, mice and hepatocytes.

Traditional pulp-capping materials like mineral trioxide aggregate (MTA) offer excellent biocompatibility and sealing, but limitations such as prolonged setting time, low bioactivity, and high costs persist. Metformin, with its potential in craniofacial regeneration, could enhance dentin synthesis by targeting pulp cells. This study aimed to: (1) develop a calcium phosphate cement with chitosan (CPCC) with improved physio-mechanical properties; (2) incorporate metformin (CPCC-Met) to assess release; and (3) evaluate human dental pulp stem cells (hDPSCs) response.

Objective: To investigate the predictive value of machine learning-based PET/CT radiomics and clinical risk factors in predicting interim efficacy in patients with follicular lymphoma (FL).

Methods: This study retrospectively analyzed data from 97 patients with FL diagnosed via histopathological examination between July 2012 and November 2023. Lesion segmentation was performed using LIFEx software, and radiomics features were extracted through the uAI Research Portal (uRP) platform, including first-order features, shape features, and texture features.

This study investigates the association between prenatal exposure to dioxin-like polychlorinated biphenyls (DL-PCBs) and glucocorticoid and androgenic hormone levels in cord blood. We analyzed cord blood samples from 500 mother-infant pairs from China (2022-2023), focusing on hormones including cortisol, cortisone, dehydroepiandrosterone (DHEA), and androstenedione. The main analysis revealed significant reductions in cortisol levels with increased exposure to PCB-77 (β = -3.

We reported the pseudoprogression in an elderly patient with advanced gastric cancer after chimeric antigen receptor (CAR)-T cell therapy. The hepatic metastases enlarged 1 month after CAR-T cell infusion and then shrunk the next month as seen through computed tomography scanning. Based on a comprehensive evaluation that includes imaging, pathology, serum tumor markers, and clinical symptoms, we arrived at a diagnosis of pseudoprogression after CAR-T cell therapy, which has not been reported in previous studies.

Introduction: In patients with acute respiratory distress syndrome, mechanical ventilation often leads to ventilation-induced lung injury (VILI), which is attributed to unphysiological lung strain (UPLS) in respiratory dynamics. Platelet endothelial cell adhesion molecule-1 (PECAM-1), a transmembrane receptor, senses mechanical signals. The Src/STAT3 pathway plays a crucial role in the mechanotransduction network, concurrently triggering pyroptosis related inflammatory responses.

This article aims to develop and validate a pathological prognostic model for predicting prognosis in patients with isocitrate dehydrogenase (IDH)-mutant gliomas and reveal the biological underpinning of the prognostic pathological features. The pathomic model was constructed based on whole slide images (WSIs) from a training set ( = 486) and evaluated on internal validation set ( = 209), HPPH validation set ( = 54), and TCGA validation set ( = 352). Biological implications of PathScore and individual pathomic features were identified by pathogenomics set ( = 100).

Background: Isocitrate dehydrogenase (IDH)-mutant gliomas generally have a better prognosis than IDH-wild-type glioblastomas, and the extent of resection significantly impacts prognosis. However, there is a lack of integrated tools for predicting outcomes based on molecular subtypes and treatment modalities. This study aimed to identify factors influencing gross total resection (GTR) rates and to develop a clinical prognostic tool for IDH-mutant gliomas.

Background: An increase in the prevalence of lung cancer that is not smoking-related has been noticed in recent years. Unfortunately, these patients are not included in low dose computer tomography (LDCT) screening programs and are not actually considered in early diagnosis. Therefore, improved early diagnosis methods are urgently needed for non-smokers.
