The histone lactylation of AIM2 influences the suppression of ferroptosis by ACSL4 through STAT5B and promotes the progression of lung cancer.

FASEB J

January 2025

Ultrasound in Cardiac Electrophysiology and Biomechanics Key Laboratory of Sichuan Province, Sichuan Provincial People's Hospital, University of Electronic Science and Technology of China, Chengdu, China.

Lung cancer progression is characterized by intricate epigenetic changes that impact critical metabolic processes and cell death pathways. In this study, we investigate the role of histone lactylation at the AIM2 locus and its downstream effects on ferroptosis regulation and lung cancer progression. We utilized a combination of biochemical assays, including chromatin immunoprecipitation (ChIP), quantitative real-time PCR (qRT-PCR), and western blotting to assess histone lactylation levels and gene expression.

Simultaneous Blockade of CD209 and CD209L by Monoclonal Antibody Does Not Provide Sufficient Protection Against Multiple Viral Infections In Vivo.

Immunology

January 2025

The Key Laboratory for Human Disease Gene Study of Sichuan Province, Department of Laboratory Medicine, Sichuan Provincial People's Hospital, University of Electronic Science and Technology of China, Chengdu, China.

Many virus species, including Ebola virus, Marburg virus, SARS-CoV-2, dengue virus (DENV) and Zika virus (ZIKV), exploit CD209 and CD209L as alternative or attachment receptors for viral cis- or trans-infection. Thus, CD209 and CD209L may be critical targets for the development of therapeutic monoclonal blocking antibody drugs to disrupt the infection process caused by multiple viruses. Here, we produced a human chimeric monoclonal blocking antibody that simultaneously blocks CD209 and CD209L, namely 7-H7-B1.

The gut-brain axis underlying hepatic encephalopathy in liver cirrhosis.

Nat Med

January 2025

Microbiome Medicine Center, Department of Laboratory Medicine, Zhujiang Hospital, Southern Medical University, Guangzhou, China.

Up to 50-70% of patients with liver cirrhosis develop hepatic encephalopathy (HE), which is closely related to gut microbiota dysbiosis, with an unclear mechanism. Here, by constructing gut-brain modules to assess bacterial neurotoxins from metagenomic datasets, we found that phenylalanine decarboxylase (PDC) genes, mainly from Ruminococcus gnavus, increased approximately tenfold in patients with cirrhosis and higher in patients with HE. Cirrhotic, not healthy, mice colonized with R.

Ras S89D mutation induced allosteric changes that promoted its nucleotide exchange and signaling activation.

Int J Biol Macromol

January 2025

Department of Pulmonary and Critical Care Medicine, Sichuan Provincial People's Hospital, School of Medicine, University of Electronic Science and Technology of China, Chengdu, China. Electronic address:

The small GTPase Ras is among the most frequently mutated genes and its mutations often drive oncogenesis across various cancers. While the role of NRas phosphorylation at S89 in the context of a Q61R mutation in melanoma genesis remains controversial, the impact of S89 phosphorylation on NRas function has not been fully elucidated. In this study, we employed the S89D phosphorylation-mimetic mutation and demonstrated that the S89D mutation alone activated all Ras isoforms by increasing the GTP-bound population, thereby promoting ERK phosphorylation and cell proliferation.

Translational Chinese Medicine Key Laboratory of Sichuan Province, Sichuan Academy of Chinese Medicine Sciences, Sichuan Institute for Translational Chinese Medicine,Chengdu, Sichuan 610041, PR China. Electronic address:

Background: Hepatic fibrosis is a wound healing response that leads to excessive deposition of extracellular matrix (ECM) due to sustained liver injury. Hepatic stellate cells (HSCs) are key players in ECM synthesis, with the TGF-β/Smad signaling pathway being central to their activation. Despite advances in understanding the pathogenesis of hepatic fibrosis, effective anti-fibrotic therapies are still lacking.

Department of Laboratory Medicine and Department of Ultrasound, Sichuan Academy of Medical Sciences, Sichuan Provincial People's Hospital, School of Medicine, University of Electronic Science and Technology of China, No. 32, West Second Section, First Ring Road, Chengdu, 610072, Sichuan, China. Electronic address:

Incomplete radiofrequency ablation (iRFA) not only leaves residual tumor, but also render the residual tumor highly self-adaptable and immunosuppressive, consequently expediting residual tumor progression including relapse. To address it, radiofrequency dynamic therapy (RFDT) with identical trigger (namely radiofrequency) has been established and enabled by polyethylene glycol (PEG)-modified Fe-based single atom nanozyme (P@Fe SAZ). P@Fe SAZ can respond to radiofrequency field to produce reactive oxygen species (ROS), attaining the nanomedicine-unlocked low-temperature RFDT.

Indication of frailty transitions on 2-year adverse health outcomes among older Chinese inpatients: Insight from a multicenter prospective cohort study.

PLoS One

January 2025

Department of Epidemiology and Statistics, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences & School of Basic Medicine, Peking Union Medical College, Dongcheng District, Beijing, China.

Introduction: Frailty is thought to be associated with an increased risk of adverse health outcomes such as death and falls, but comparatively little is known about the impact of frailty transitions on the adverse health outcomes. Moreover, owing to insufficient sample size or a single-center study design, previous studies have not been sufficiently representative of elderly inpatients in China. This study aimed to provide estimates at the population level of the association between frailty transitions and adverse outcomes among elderly inpatients following discharge.

Jiangsu Key Laboratory of Infection and Immunity, Institutes of Biology and Medical Sciences, Soochow University, Suzhou 215123, Jiangsu, China.

Chronic hepatitis B (CHB) caused by HBV infection has brought suffering to numerous people. Due to the stable existence of HBV cccDNA, the original template for HBV replication, chronic hepatitis B (CHB) is difficult to cure completely. Despite current antiviral strategies being able to effectively limit the progression of CHB, complete CHB cure requires directly targeting HBV cccDNA.

IFN alpha signaling drives hematopoietic stem cells malfunction under acute inflammation.

Int Immunopharmacol

January 2025

Department of Hematology, Guangzhou First People's Hospital, South China University of Technology, Guangzhou, Guangdong, China. Electronic address:

Article Synopsis
  • Inflammation triggers the activation of hematopoietic stem cells (HSCs) via direct sensing of lipopolysaccharide (LPS) through toll-like receptor 4 (TLR4) and cytokine release.
  • The study found that LPS stimulation leads to the activation of the interferon alpha (IFNα) signaling pathway, resulting in both the activation and eventual exhaustion of HSCs.
  • Creatine, an inhibitor of IFNα, can prevent HSC activation and exhaustion caused by LPS, while a deficiency in the IFNα receptor (IFNAR) offers protection to HSCs during inflammation, indicating that LPS injuries HSCs through both direct and indirect pathways.
