Adv Sci (Weinh)

December 2024

Institute for Safflower Industry Research, Key Laboratory of Xinjiang Phytomedicine Resource and Utilization (Ministry of Education), School of Pharmacy, Shihezi University, Shihezi, 832003, China.

Prostate specific antigen (PSA) is widely used in liquid biopsy of prostate cancer (PCa) but still faces challenges due to the poor specificity. Herein, this study reports a double-SERS satellite immunoassay, made of an Au-Ag dealloyed intra-nanogap nanoflower (Au-Ag DINF) with strong SERS signals and Au magnetic nanoparticles (AuMNPs) with magnetic capture and SERS amplification, for sensing multiple PSA (free PSA (fPSA), complexed PSA (cPSA) and [-2]proPSA (p2PSA)) toward potential PCa screening. Unlike the previous studies focus on the tPSA and fPSA/tPSA ratio (f/t PSA%), this work introduces a multiple PSA-mediated Prostate Health Index (PHI) assay with significantly increased the predictive accuracy and specificity of PCa, especially the patients with a tPSA level in the "diagnostic gray zone".

A Lipiodol Pickering Emulsion Stabilized by Iron-Doped Carbon Nanozymes for Liver Transarterial Chemoembolization.

Adv Sci (Weinh)

December 2024

Department of Interventional Center, Biomedical Innovation Center, The Sixth Affiliated Hospital, Sun Yat-Sen University, Guangzhou, 510655, P. R. China.

Transarterial chemoembolization (TACE) utilizing a water-in-oil lipiodol emulsion is a preferable therapeutic strategy for advanced liver cancer in clinical practice. However, the low stability of the lipiodol emulsion and poor efficacy of chemotherapeutic drug seriously undermine the efficiency of TACE. Herein, a novel lobaplatin-loaded lipiodol emulsion (denoted as ICN-LPE) is developed by constructing a lipiodol Pickering emulsion (LPE) stabilized with iron-doped carbon nanozymes (ICN) to mitigate the issue of lipiodol-water separation.

The Department of Anesthesiology, Affiliated Hospital of Guangdong Medical University, Zhanjiang, Guangdong 524000, China; Guang Dong Medical University, Zhanjiang, Guangdong 524000, China. Electronic address:

Tank-binding kinase 1 (TBK1) is a critical signal transducer in the nuclear factor κB (NF-κB) and interferon regulatory factor (IRF) pathways, essential for innate immunity. However, its negative regulation mechanisms remain unclear. This study demonstrates that TBK1 succinylation, regulated by desuccinylase SIRT5, inhibits lipopolysaccharide (LPS)/Toll-like receptor 4 (TLR4)-mediated NF-κB and IRF signaling activation.

Dongguan Key Laboratory of Public Health Laboratory Science, The First Dongguan Affiliated Hospital, School of Public Health, Guangdong Medical University, Dongguan 523808, China. Electronic address:

Article Synopsis
  • Environmental arsenic contamination often exceeds safety levels in drinking water and is linked to higher rates of H. pylori infections, leading to concerns about the combined effects of both hazards.
  • A study using a mouse model found that exposure to both H. pylori and inorganic arsenic resulted in significant changes in intestinal flora composition and metabolic processes.
  • The research suggests that H. pylori may worsen the imbalance in gut bacteria and disrupt liver metabolism caused by arsenic, which could heighten sensitivity to heavy metal toxicity.

J Endocr Soc

November 2024

Department of Thoracic Surgery, Guangdong Cardiovascular Institute, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical University, Guangzhou, 510080 Guangdong, China.

Background: Cardiovascular disease (CVD) is the leading cause of noncancer-related mortality among differentiated thyroid cancer (DTC) survivors, which accounts for a large portion of subsequent primary malignancies in childhood cancer survivors. This study aims to assess the risk of cardiovascular mortality among DTC as a second primary malignancy (DTC-2) patients compared with DTC as a first primary malignancy (DTC-1) and the general population.

Methods: Using the Surveillance, Epidemiology, and End Results database, we conducted a population-based cohort study including 159 395 DTC-1 and 20 010 DTC-2 patients diagnosed older than 30 between 1975 and 2020 and the corresponding US population (71 214 642 person-years; 41 420 893 cardiovascular deaths).

Restoration of disc height and biomechanical function is essential for intervertebral disc degeneration (IDD) treatment. Removing abnormal nucleus pulposus (NP) tissue is an important step to facilitate bony fusion during the healing process. We analyzed publicly available single-cell transcriptome data for human normal and degenerative NP to identify genes associated with NP degeneration.

Department of Human Cell Biology and Genetics, Joint Laboratory of Guangdong-Hong Kong Universities for Vascular Homeostasis and Diseases, School of Medicine, Southern University of Science and Technology, Shenzhen, Guangdong 518055, China.

PFKP Phosphofructokinase, Platelet Type isoform), as an essential metabolic enzyme, contributes to the high glycolysis rates seen in cancers while its role in oncogenic pathways, especially from a non-metabolic aspect, is not fully understood. We found that PFKP was highly expressed in NSCLC and was related to poor patient survival. Knockdown of PFKP significantly inhibited cell proliferation, colony formation, invasion, and migration of NSCLC cells.

Background: Metabolic-associated fatty liver disease (MAFLD) is a public health concern. Transforming growth factor-β1(TGF-β1) plays an important regulatory role in multiple MAFLD stages, as it can promote the expression of matrix metalloproteinase-9 (MMP9) and promote liver fibrosis. Sorting nexin protein-10 (SNX-10) may be involved in the occurrence and development of fatty liver disease.

Promoting wound nerve regeneration and synchronously initiating angiogenesis are critical factors in the healing process of diabetic wounds. However, existing research on diabetic wounds mainly focuses on angiogenesis, bacterial infection and reactive oxygen species, often failing to coordinate neurogenesis and angiogenesis. To coordinate the symbiosis of nerves and blood vessels in the diabetic wounds, we successfully designed a multifunctional chitosan (CS)-based sponges by regulating the structure of CS specifically for diabetic wound healing.

Article Synopsis
  • The study explored how a specific circular RNA, circFNDC3B, influences the development of abdominal aortic aneurysm (AAA) by analyzing its expression levels in affected vs. normal tissues.
  • Researchers used various assays to understand circFNDC3B's biological functions and molecular mechanisms, confirming that it is significantly more expressed in AAA tissues and has effects on vascular smooth muscle cell behavior.
  • The findings indicate that circFNDC3B contributes to AAA progression by acting as a sponge for miR-1270, increasing levels of PDCD10, which is essential for understanding potential therapeutic targets for AAA treatment.

Institute of Laboratory Medicine, Guangdong Provincial Key Laboratory of Medical Molecular Diagnostics, School of Medical Technology, The First Dongguan Affiliated Hospital, Dongguan Key Laboratory of Environmental Medicine, Guangdong Medical University, Dongguan, 523000, China. Electronic address:

Progranulin (PGRN) is overexpressed and implicated in hepatocellular carcinoma (HCC) development; however, its post-translational modifications and regulatory mechanisms in HCC remain largely unexplored. Here, the expression levels of PGRN, OGT, and O-GlcNAcylation were found to be elevated in both HCC samples and cell lines. LC-MS/MS analysis and immunoprecipitation revealed that PGRN underwent O-linked N-acetylglucosamine (O-GlcNAc) modification at threonine 272 (Thr272).

Numerous studies have substantiated the pivotal role of long non-coding RNAs (lncRNAs) in the progression of non-small cell lung cancer (NSCLC) and the prognosis of afflicted patients. Notably, individuals with NSCLC may exhibit heightened vulnerability to the novel coronavirus disease (COVID-19), resulting in a more unfavorable prognosis subsequent to infection. Nevertheless, the impact of COVID-19-related lncRNAs on NSCLC remains unexplored.
