Osteosarcoma is an aggressive malignant bone tumor with an obscure etiology, as well as high prevalence and poor prognosis in children and adolescents. We aimed to investigate the pathogenesis of osteosarcoma through a comprehensive analysis of the tumor immune microenvironment (TIME) using multiple single-cell RNA sequencing datasets. SLC25A5, a gene implicated in cellular aging, significantly influenced osteosarcoma development by altering the TIME and promoting CD8+ T cell exhaustion, which contributed to reduced chemosensitivity.

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.

Anal Methods

January 2025

Microelectronic Research & Development Center, School of Mechatronics Engineering and Automation, Shanghai University, Shanghai 200444, China.

An integrated magnetoimpedance (MI) biosensor microfluidic magnetic platform was proposed for the evaluation of the cardiac marker, cardiac troponin I (cTnI). This bioanalyte evaluation platform mainly comprised three external permanent magnets (PMs), one MI element, two peelable SiO film units and a microfluidic chip (MFC). The MI element was made of micro-electro-mechanical system (MEMS)-based multilayered [Ti (6 nm)/FeNi (100 nm)]/Cu (400 nm)/[Ti (6 nm)/FeNi (100 nm)] thin films and designed as meander structures with closed magnetic flux.

Background: Acute myocardial infarction (AMI), particularly ST-segment elevation myocardial infarction (STEMI), significantly impacts global health, exacerbated by risk factors such as diabetes mellitus (DM). While the Gensini score effectively quantifies coronary artery lesions, its correlation with fasting blood glucose (FBG) levels, particularly in a non-linear fashion, has not been thoroughly explored in STEMI patients.

Methods: This study analyzed data from 464 STEMI patients treated with percutaneous coronary intervention at the First People's Hospital of Taizhou City, Zhejiang Province, China, from January 2010 to October 2014.

Leucine-rich repeat kinase 2 (LRRK2) is a ROCO family member which its mutation is closely related with Parkinson's disease, and LRRK2 is widely involved into the regulation of autophagy, vesicle transport and neuronal proliferation. However, the roles of LRRK2 during mammalian oocyte maturation are still largely unclear. In present study, we disturbed the activity of LRRK2 and showed its essential roles in porcine oocytes.

State Key Laboratory of Organ Failure Research, Department of Cell Biology, School of Basic Medical Sciences, Southern Medical University, Guangzhou, 510515, China.

Intervertebral disc degeneration (IDD), osteoarthritis (OA), and osteoporosis (OP) are common musculoskeletal disorders (MSDs) with similar age-related risk factors, representing the leading causes of disability. However, successful therapeutic development and translation have been hampered by the lack of clinically-relevant animal models. In this study, we investigated the potential suitability of the tree shrew, a small mammal with a close genetic relationship to primates, as a new animal model for MSDs.

Chimeric antigen receptor (CAR) T-cell therapy has exhibited remarkable efficacy in the treatment of haematological malignancies, yet its application in solid tumours is hindered by the immunosuppressive tumour microenvironment (TME). In this study, a novel SS1-TREM1/DAP12-BB CAR-T cell was devised to target ovarian cancer and further engineered to co-express the dominant-negative TGF-β receptor 2 (DNR) to combat CAR-T cell exhaustion in TME. The incorporation of DNR effectively blocked TGF-β signalling, thereby enhancing CAR-T cell survival and antitumor activity in a TGF-β1-rich environment.

Colorectal cancer (CRC) is one of the major cancers threatening human health, with high mortality, tumor drug resistance and metastasis, considered to be one of the most difficult diseases to treat. Due to its advantages of non-invasive, strongly targeted and limit side effects, Photodynamic therapy (PDT) has become a promising primary treatment for CRC. Remarkably, PDT has been shown to activate T cell-adaptive immune response and induce immunogenic cell death (ICD).

Background: Cervical spine pyogenic infection (CSPI) is a rare and challenging form of spinal infection that is typically caused by pyogenic bacteria and primarily affects the cervical vertebral bodies and surrounding tissues. Given its nonspecific symptoms, such as fever and neck pain, early diagnosis is crucial to prevent severe complications, including spinal cord injury. We report a previously unreported case of acute CSPI arising from chronic paronychia, exploring its diagnostic and therapeutic challenges through a review of the current literature.

Exosomal miR-552-5p Regulates the Role of NK Cells in EMT of Gastric Cancer via the PD-1/PD-L1 Axis.

J Cancer

January 2025

Department of Gastroenterology and Respiratory Internal Medicine & Endoscopy Center, Guangxi Medical University Cancer Hospital, Nanning, Guangxi 530021, P.R. China.

While previous studies have established the role of exosomal miR-552-5p in promoting gastric cancer (GC) progression, the exact mechanisms through which it modulates the PD-1/PD-L1 axis to affect NK cell function and subsequently influence GC epithelial-mesenchymal transition (EMT) remain to be elucidated. Western blot, transmission electron microscopy (TEM), and nanoparticle tracking analysis were used to characterize exosomes that were isolated from GC cell supernatants. Subcutaneous AGS cell injections expressing either Lv-miR-552-5p or Lv-NC were administered to nude BALB/C mice.

Relevant studies have demonstrated that plasma metabolites and immune cell characteristics are closely related to colorectal cancer (CRC). However, the causal relationship among these factors remains unclear, particularly regarding whether immune cell traits mediate the causal link between plasma metabolites and CRC. This study employed a two-step, two-sample Mendelian randomization (MR) using summary data from genome-wide association studies (GWAS) to assess causal associations between 1,400 plasma metabolites, 731 immune cell traits, and CRC.

Coronary microembolization (CME) is defined as atherosclerotic plaque erosion, spontaneous rupture, or rupture of the plaque while undergoing interventional therapy resulting in the formation of tiny emboli that obstruct the coronary microcirculatory system. For percutaneous coronary intervention, CME is a major complication, with a periprocedural incidence of up to 25%. Recent studies have demonstrated that regulatory cell death (RCD) exerts a profound influence on CME through its modulation of inflammatory responses, oxidative stress, cell death, and angiogenesis.
