IDH1 mutation inhibits differentiation of astrocytes and glioma cells with low oxoglutarate dehydrogenase expression by disturbing α-ketoglutarate-related metabolism and epigenetic modification.

Life Metab

April 2024

State Key Laboratory of Holistic Integrative Management of Gastrointestinal Cancers, Department of Pathology, Xijing Hospital and School of Basic Medicine, Fourth Military Medical University, Xi'an, Shaanxi 710032, China.

Isocitrate dehydrogenase (IDH) mutations frequently occur in lower-grade gliomas and secondary glioblastomas. Mutant IDHs exhibit a gain-of-function activity, leading to the production of D-2-hydroxyglutarate (D-2HG) by reducing α-ketoglutarate (α-KG), a central player in metabolism and epigenetic modifications. However, the role of α-KG homeostasis in IDH-mutated gliomagenesis remains elusive.

BMC Public Health

January 2025

Department of Psychiatry, Renmin Hospital of Wuhan University, No. 6 of Gaoxin Road, East Lake High-tech Development Zone, Wuhan, Wuhan City, 430060, Hubei Province, China.

Background: Although Internet has become the main way of access to health and medical information for most young people today, it might not be the case with older people. The elderly that have difficulty using the Internet rely largely on their family members to obtain and evaluate online health and medical information.

Objective: The purpose of this study is to investigate medical students' proxy health information seeking behavior for their family members, and to look into how they search, evaluate, and even apply health information from the Internet.

Background: Given the close relationship between excessive cortisol secretion and obesity, as well as their intimate associations with cardiometabolic sequelae, this study aimed to evaluate whether elevated cortisol levels and obesity are independently and potentially interactively related to hypertension-mediated organ damage (HMOD) in patients with untreated hypertension.

Methods: A total of 936 untreated hypertensive patients were recruited. Body mass index (BMI), 24-hour urinary free cortisol (24 h UFC), and HMOD indicators, including left ventricular hypertrophy (LVH), carotid intima-media thickness (CIMT), and albuminuria, were assessed.

Human breast milk-derived exosomes and their positive role on neonatal intestinal health.

Pediatr Res

January 2025

Department of Pediatrics, Guangzhou Eighth People's Hospital, Guangzhou Medical University, Guangzhou, 510623, China.

Although the role of breast milk in promoting neonatal growth and maintaining intestinal homeostasis is well established, underlying mechanisms by which it protects the intestine from damage remain to be elucidated. Human breast milk-derived exosomes (HMDEs) are newly discovered active signaling vesicles with a diameter of 30-150 nm, which are key carriers of biological information exchange between mother and child. In addition, due to their ability to cross the gastrointestinal barrier, low immunogenicity, good biocompatibility and stability, HMDEs play an important role in regulating intestinal barrier integrity in newborns.

Center for High Pressure Science, State Key Laboratory of Metastable Materials Science and Technology, Yanshan University, Qinhuangdao, 066004, China.

Hydrous aluminosilicates are important deep water-carriers in sediments subducting into the deep mantle. To date, it remains enigmatic how hydrous aluminosilicates withstand extremely high temperatures in the mantle transition zone. Here we systematically investigate the crystal structures and chemical compositions of typical hydrous aluminosilicates using single-crystal X-ray diffraction, electron probe microanalyzer, and nanoscale secondary ion mass spectrometry.

Department of Surgery of Spine and Spinal Cord, Henan Provincial People's Hospital, People's Hospital of Zhengzhou University, People's Hospital of Henan University, No.7 Weiwu Road, Zhengzhou, Henan, 450003, China.

Osteoarthritis (OA) is an age-related degenerative joint disease, prominently influenced by the pro-inflammatory cytokine interleukin-6 (IL-6). Although elevated IL-6 levels in joint fluid are well-documented, the uneven cartilage degeneration observed in knee OA patients suggests additional underlying mechanisms. This study investigates the role of interleukin-6 receptor (IL-6R) in mediating IL-6 signaling and its contribution to OA progression.

Thiol-Enhanced Interfacial and Internal Deposition of Metal-Polyphenol Networks for Permanent Hair Dyeing.

ACS Biomater Sci Eng

February 2025

Key Laboratory of Synthetic and Biological Colloids, Ministry of Education, School of Chemical & Material Engineering, Jiangnan University, Wuxi, Jiangsu 214122, China.

Metal polyphenolic networks (MPNs) are becoming more and more attractive for nontoxic hair dyeing, but their coloring effect is not satisfactory because of the limited interfacial deposition and the absence of internal deposition. Moreover, there is a lack of understanding of the driving factors of the interfacial deposition of MPNs on hair. Herein, we develop a simple yet efficient strategy that transforms disulfide bonds of the hair into thiol groups by thioglycolic acid (TGA) to highly enhance the coloring effect of MPNs at a low temperature.

The LIM-domain-only protein LMO2 and its binding partner LDB1 are differentially required for class switch recombination.

Proc Natl Acad Sci U S A

January 2025

Department of Immunology and Microbiology, Key Laboratory of Tropical Disease Control of Ministry of Education, Zhongshan School of Medicine, Sun Yat-sen University, Guangzhou, Guangdong 510000, China.

The LIM-domain-only protein LMO2 interacts with LDB1 in context-dependent multiprotein complexes and plays key roles in erythropoiesis and T cell leukemogenesis, but whether they have any roles in B cells is unclear. Through a CRISPR/Cas9-based loss-of-function screening, we identified LMO2 and LDB1 as factors for class switch recombination (CSR) in murine B cells. LMO2 contributes to CSR at least in part by promoting end joining of DNA double-strand breaks (DSBs) and inhibiting end resection.
