Prenatal dexamethasone exposure reduces osteoprogenitor proliferation in mice via histone modifications at the Mkp-1 gene locus.

Commun Biol

November 2024

Division of Orthopaedics and Traumatology, Department of Orthopaedics, Nanfang Hospital, Southern Medical University, No.1838 North of Guangzhou Avenue, Guangzhou, 510515, Guangdong Province, China.

Article Synopsis
  • - Prenatal exposure to dexamethasone leads to long-term negative effects on bone development in offspring, including lower bone mass and fewer bone-building cells (osteoblasts).
  • - The study identifies that dexamethasone increases the expression of MKP-1 and affects histone modifications related to the Mkp-1 gene, which suppresses the growth of osteoprogenitor cells.
  • - Treatments aimed at restoring histone methylation can counteract the negative effects of prenatal dexamethasone exposure, improving osteoprogenitor proliferation and bone development in the offspring.

Phototheranositcs has recently aroused extreme attention due to its exceptional advantages. However, the poor photothernostic efficiency, limited penetration depth, strong oxygen-dependence, and inevitable damage to normal tissue of conventional photothernostic materials severely hindered their total theranostic efficacy. Herein, a series of near-infrared second (NIR-II) photosensitizers (PSs) featuring aggregation-induced emission (AIE), NIR-II fluorescence imaging (FLI), type I photodynamic therapy (PDT) and mild-temperature photothermal therapy (PTT) are constructed through dual-strategy methods combining donor group engineering and fluorination engineering.

YTHDF2 promotes anaplastic thyroid cancer progression by activating the DDIT4/AKT/mTOR signaling pathway.

Biol Direct

November 2024

Department of Thyroid and Hernia Surgery, Guangdong Provincial People's Hospital, Guangdong Academy of Medical Sciences, Southern Medical University, Guangzhou, Guangdong, 510080, China.

Article Synopsis
  • YTHDF2 is a key player in anaplastic thyroid cancer (ATC), with its expression significantly increased in cancerous tissues.
  • Research reveals that when YTHDF2 is knocked down, it inhibits ATC cell growth and metastasis, while overexpression of YTHDF2 has the opposite effect.
  • The mechanism involves YTHDF2 promoting the degradation of DDIT4 mRNA, leading to activation of the AKT/mTOR signaling pathway, which in turn drives tumor progression in ATC.

Emerging role of microglia in the developing dopaminergic system: perturbation by early life stress.

Neural Regen Res

November 2024

Guangzhou Key Laboratory of Formula-Pattern of Traditional Chinese Medicine, School of Traditional Chinese Medicine, Jinan University, Guangzhou, Guangdong Province, China.

Early life stress correlates with a higher prevalence of neurological disorders, including autism, attention-deficit/hyperactivity disorder, schizophrenia, depression, and Parkinson's disease. These conditions, primarily involving abnormal development and damage of the dopaminergic system, pose significant public health challenges. Microglia, as the primary immune cells in the brain, are crucial in regulating neuronal circuit development and survival.

Cardiac differentiation of human pluripotent stem cells is not only a new strategy of regenerative therapy for cardiovascular disease treatment but also provides unique opportunities for the study of in vitro disease models and human heart development. To elucidate the dynamic gene regulatory networks and pivotal regulators involved in the cardiomyocyte differentiation process, we conducted an analysis of single-cell RNA sequencing data obtained from the reprogramming of two human induced pluripotent stem cell (iPSC) lines into cardiomyocytes. The data were collected from 32,365 cells at 4 stages of this process.

Article Synopsis
  • This study explored how sleep disorders affect taste dysfunction in adults over 40, specifically looking at the role of oral microbes.
  • Using data from a national health survey and statistical models, it was found that individuals with sleep disorders had a 36% higher likelihood of experiencing taste issues.
  • Although no significant differences were observed between various demographic groups, the presence of sleep disorders correlated with changes in oral microbiota diversity, although the microbiome did not seem to mediate the relationship between sleep disorders and taste dysfunction.

Introduction: Necrotising enterocolitis (NEC) of the intestine of preterm infants leads to the risk of abdominal surgery, short bowel syndrome, neurodevelopmental disorders and death. Although the risks of NEC and its complications have been recognised in many countries, few countries have established NEC-specific registries to continuously monitor its aetiology and prognosis. In China, the understanding of risk factors and prognosis of NEC is incomplete, characterised by a lack of evidence from prospective and multicentre studies.

Evidence suggests that Lactiplantibacillus plantarum (LP) can positively influence gut microbiota, subsequently affecting brain function via the gut-brain axis. However, the oral administration of LP may subject it to damage from gastric acid. To address this issue, a microencapsulation system was developed to protect LP and enhance its viability in the gastrointestinal tract.

Electronic address:

Background: There is increasing evidence of a link between Epstein-Barr virus (EBV) and gastrointestinal cancers, particularly in immunocompromised patients and those on thiopurines. Traditional endoscopic techniques have limitations in diagnosing EBV, whereas standard methods for diagnosing EBV have practical challenges in regular clinical settings related to their invasiveness and high costs.

Methods: An explainable AI (XAI) model was developed to analyze 1598 endoscopic images from 287 patients with inflammatory bowel disease (IBD), with a focus on detecting EBV infection.

State Key Laboratory of Medical Proteomics and Shenzhen Key Laboratory of Functional Proteomics, Department of Chemistry and Research Center for Chemical Biology and Omics Analysis, School of Science and Guangming Advanced Research Institute, Southern University of Science and Technology, Shenzhen, China.

Despite the advances in antibody-guided cell typing and mass spectrometry-based proteomics, their integration is hindered by challenges for processing rare cells in the heterogeneous tissue context. Here, we introduce Spatial and Cell-type Proteomics (SCPro), which combines multiplexed imaging and flow cytometry with ion exchange-based protein aggregation capture technology to characterize spatial proteome heterogeneity with single-cell resolution. The SCPro is employed to explore the pancreatic tumor microenvironment and reveals the spatial alternations of over 5000 proteins by automatically dissecting up to 100 single cells guided by multi-color imaging of centimeter-scale formalin-fixed, paraffin-embedded tissue slide.

With the progression of global aging, neurological diseases in elderly individuals have aroused widespread interest among researchers. Imbalances in the homeostasis of neuronal microenvironments, including neural progenitor cells and microglia, are the leading cause of worsening neurodegenerative diseases. The aging of various glial cells can further lead to abnormal functions in the central nervous system (CNS).

There is currently a lack of pathological research on the hair loss caused by stress, and there is no effective treatment available. It has been previously reported that stress can cause sympathetic nerve activation and release of norepinephrine, which binds to beta-2 adrenergic receptors and causes a series of chemical reactions. Propranolol, as a beta-2 adrenergic receptors blocker, competitively antagonizes the effects of norepinephrine.
