School of Pharmacy, Key Laboratory of Molecular Pharmacology and Drug Evaluation (Yantai University), Ministry of Education, Collaborative Innovation Center of Advanced Drug Delivery System and Biotech Drugs in Universities of Shandong, Yantai University, Yantai, Shandong, 264005, China.

Despite significant advances in targeted therapies and immunotherapies, non-small cell lung cancer (NSCLC) continues to present a global health challenge, with a modest five-year survival rate of 28 %, largely due to the emergence of treatment-resistant and metastatic tumors. In response, we synthesized a novel bioactive compound, ethyl 6-chlorocoumarin-3-carboxylyl L-theanine (TClC), which significantly inhibited NSCLC growth, epithelial mesenchymal transition (EMT), migration, and invasion and tumor growth and metastasis without inducing toxicity. TClC disrupts autocrine loops that promote tumor progression, particularly in stem-like CD133-positive NSCLC (CD133+ LC) cells, which are pivotal in tumor metastasis.

Lancet Reg Health West Pac

January 2025

State Key Laboratory of Pathogen and Biosecurity, Academy of Military Medical Science, Beijing, PR China.

Background: Co-existence of efficient transportation networks and geographic imbalance of medical resources greatly facilitated inter-city migration of patients of infectious diseases in China.

Methods: To characterize the migration patterns of major notifiable infectious diseases (NIDs) during 2016-2020 in China, we collected migratory cases, who had illness onset in one city but were diagnosed and reported in another, from the National Notifiable Infectious Disease Reporting System, and conducted a nationwide network analysis of migratory cases of major NIDs at the city (prefecture) level.

Findings: In total, 2,674,892 migratory cases of NIDs were reported in China during 2016-2020.

Background: Pulmonary embolism (PE) as a preventable and potentially fatal noncommunicable disease was believed to have a lower incidence in Asian populations compared to Western populations. However, the incidence and mortality rates of PE in China and the impact of venous thromboembolism (VTE) prevention system constructions on PE still lack nationwide evidence.

Methods: For this nationwide hospital-based observational study, we used data from the National Hospital Quality Monitoring System (HQMS) and public database in China.

Background: Acute variceal bleeding (AVB), a life-threatening complication of liver cirrhosis, can be effectively treated by endoscopy, but there is a risk of early rebleeding after endoscopic variceal treatment (EVT). Thrombocytopenia is the most common hemostatic abnormality in liver cirrhosis. However, it is still unclear about whether thrombocytopenia increases the failure of EVT in cirrhotic patients with AVB.

IGF2-IGF1R signaling inhibition delays the growth of IGF2-high colorectal cancer by modulating MDSCs.

Biochem Biophys Res Commun

February 2025

Institute of Cancer, Xinqiao Hospital, Third Military Medical University, Chongqing, 400037, China; Department of Oncology, PLA Rocket Force Characteristic Medical Center, Beijing, 100088, China. Electronic address:

Approximately 22 % of human colorectal cancers (CRC) are characterized by IGF2 overexpression, and the tumor-promoting role of IGF2 has been widely reported. Despite promising preclinical results, IGF2 signaling inhibition therapy has exhibited limited efficacy in treating unselected patients with CRC. Recent evidence suggests that IGF2-high CRC are more sensitive to IGF2 signaling blockade therapy in immune-deficient mice, suggesting that IGF2-high CRC can benefit from IGF2 signaling blockade therapy.

CYP3A5 promotes glioblastoma stemness and chemoresistance through fine-tuning NAD/NADH ratio.

J Exp Clin Cancer Res

January 2025

School of Medicine, Chinese PLA General Hospital, Nankai University, Beijing, China.

Background: Glioblastoma multiforme (GBM) exhibits a cellular hierarchy with a subpopulation of stem-like cells known as glioblastoma stem cells (GSCs) that drive tumor growth and contribute to treatment resistance. NAD(H) emerges as a crucial factor influencing GSC maintenance through its involvement in diverse biological processes, including mitochondrial fitness and DNA damage repair. However, how GSCs leverage metabolic adaptation to obtain survival advantage remains elusive.

The nanoengager strategy, which enhances receptor signaling responsiveness through a multivalent ligand binding mode, offers a promising approach for improving immune cell redirecting therapy. Increasing nanomaterial platforms have been developed for constructing more flexible and multifunctional nanoengagers, but the different mediating mechanisms from their multivalent nanostructures, compared to original monomolecule engagers, have rarely been discussed. Here, we constructed dual-specificity T cell nanoengagers (TNEs) targeting CD3 and PDL1 receptors based on a polyethylene glycol--polylactic acid (PEG--PLA)-assembled nanoparticle and specifically studied the impact of surface antibody valences on their functional mechanisms, thereby enhancing the structural advantages of TNEs against solid tumors.

Background: The global burden of metabolic diseases is increasing, but estimates of their impact on primary liver cancer are uncertain. We aimed to assess the global burden of primary liver cancer attributable to metabolic risk factors, including high body mass index (BMI) and high fasting plasma glucose (FPG) levels, between 1990 and 2021.

Methods: The total number and age-standardized rates of deaths and disability-adjusted life years (DALYs) from primary liver cancer attributable to each metabolic risk factor were extracted from the Global Burden of Disease Study 1990-2021.

Loss of Mist1 alters the characteristics of Paneth cells and impacts the function of intestinal stem cells in physiological conditions and after radiation injury.

J Pathol

February 2025

Radiation Oncology Key Laboratory of Sichuan Province, Department of Experimental Research, Sichuan Cancer Hospital & Institute, Sichuan Clinical Research Center for Cancer, Sichuan Cancer Center, Affiliated Cancer Hospital of University of Electronic Science and Technology of China, Chengdu, PR China.

Intestinal stem cells (ISCs) and Paneth cells (PCs) reside at the bottom of the crypts of Lieberkühn in the small intestine. Recent studies have shown that the transcription factor Mist1, also named BHLHA15, plays an important role in the maturation of PCs. Since there is an intimate interaction between PCs and ISCs, we speculated that the loss of Mist1 could impact these two neighboring cell types.

  • Ripk3 is key in acute lung injury (ALI) by driving endothelial cell damage and inflammation, although the exact mechanisms are not fully understood.
  • Studies using Ripk3-deficient mice revealed that removing Ripk3 improved lung tissue health, decreased inflammation, oxidative stress, and endothelial dysfunction after exposure to lipopolysaccharide (LPS).
  • Ripk3 was found to inhibit the AMPK pathway and promote necroptosis in endothelial cells by affecting mitochondrial function, suggesting it could be a target for new treatments for ALI.

This study investigates the role of Fundc1 in cardiac protection under high-altitude hypoxic conditions and elucidates its underlying molecular mechanisms. Using cardiomyocyte-specific knockout ( ) mice, we demonstrated that deficiency exacerbates cardiac dysfunction under simulated high-altitude hypoxia, manifesting as impaired systolic and diastolic function. Mechanistically, we identified that Fundc1 regulates cardiac function through the mitochondrial unfolded protein response (mito-UPR) pathway.

Article Synopsis
  • The study aimed to prepare antioxidant-capable mesenchymal stem cells (AO-MSC) from human umbilical cords and assess their biological properties.
  • The AO-MSC were isolated using a method that involved allowing tissue debris to adhere to the culture surface, while control cells were obtained through traditional collagenase digestion.
  • Results demonstrated that AO-MSC displayed higher levels of antioxidant substances and good self-renewal ability, but had a weaker capacity for adipogenic and osteogenic differentiation compared to conventional MSC.
