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.

Despite the growing interest in Phosphoenolpyruvate carboxykinase 2 (PCK2) as a potential biomarker in cancer research, studies on its clinical relevance and biological processes in glioblastoma are still unexplored. Three main glioma cohorts (TCGA, CGGA, Rembrandt) were extracted to exploit the association between PCK2 expression and clinical relevance through Kaplan-Meier survival analysis, univariate and multivariate cox regression analysis. Immunohistochemistry was used to detect PCK2 expression in glioma samples.

NCAPG promotes the progression of endometrial cancer (EC) through PI3K-AKT pathway and has potential as a novel tumor marker. However, the precise regulatory mechanism of NCAPG remains inadequately understood. In this study, we applied Assay for Transposase Accessible Chromatin with high-throughput sequencing (ATAC-Seq) analysis combined with chromatin immunoprecipitation-qPCR (CHIP) and Co-Immunoprecipitation (CoIP) analysis to analysis for the first time that NCAPG promotes EC cell proliferation, migration and invasion by affecting the binding of LEF1 to chromatin, thereby affecting the transcription of downstream SEMA7A.

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.

January 2025

Department of Thyroid and Hernia Surgery, Shengli Clinical Medical College of Fujian Medical University, Fujian Provincial Hospital, Fuzhou University Affiliated Provincial Hospital, Fuzhou City, Fujian Province 350001, China.

Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, and patients with the BRAF mutation often exhibit aggressive tumor behavior. Here, we identified Arylsulfatase I (ARSI) as a gene whose expression was significantly upregulated in BRAF PTC and was associated with poor prognosis. High ARSI expression correlated with advanced disease stage, BRAF mutation, and worse overall survival in PTC patients.

Post-translational modifications (PTMs) alter protein conformation by covalently attaching functional groups to substrates, influencing their biological activity, mechanisms of action, and functional performance. PTMs and their interactions are essential to many critical signal transduction processes, including tumor transformation, cancer progression, and metastasis in pancreatic cancer. Additionally, advancements in tumor immunotherapy indicate that PTMs are essential in immune cell activation, transport, and energy metabolism.

Accurate diagnosis and assessment of breast cancer treatment responses are critical challenges in clinical practice, influencing patient treatment strategies and ultimately long-term prognosis. Currently, diagnosing breast cancer and evaluating the efficacy of neoadjuvant immunotherapy (NAIT) primarily rely on pathological identification of tumor cell morphology, count, and arrangement. However, when tumors are small, the tumors and tumor beds are difficult to detect; relying solely on tumor cell identification may lead to false negatives.

The role of RGC degeneration in the pathogenesis of glaucoma.

Int J Biol Sci

January 2025

Department of Ophthalmology, The Second Hospital of Jilin University, Jilin University, Changchun 130000, Jilin, China.

Glaucoma is a neurodegenerative disorder marked by the loss of retinal ganglion cells (RGCs) and axonal degeneration, resulting in irreversible vision impairment. While intraocular pressure (IOP) is presently acknowledged as the sole modifiable risk factor, the sensitivity of RGCs to IOP varies among individuals. Consequently, progressive vision loss may ensue even when IOP is effectively managed.
