Abstract Glutamine is one of the most abundant non-essential amino acids in human plasma and plays a crucial role in many biological processes of the human body. Tumor cells take up a large amount of glutamine to meet their rapid proliferation requirements, which is supported by the upregulation of glutamine transporters. Targeted inhibition of glutamine transporters effectively inhibits cell growth and proliferation in tumors. Among all cancers, digestive system malignant tumors (DSMTs) have the highest incidence and mortality rates, and the current therapeutic strategies for DSMTs are mainly surgical resection and chemotherapy. Due to the relatively More > Graphic Abstract

Abstract Background: Oral cancer, a malignancy that is prevalent worldwide, is often diagnosed at an advanced stage. MicroRNAs (miRNAs) in circulating exosomes have emerged as promising cancer biomarkers. The role of miRNA let-7c-5p in oral cancer remains underexplored, and its potential involvement in tumorigenesis warrants comprehensive investigation. Methods: Serum samples from 30 patients with oral cancer and 20 healthy controls were used to isolate exosomes and quantify their RNA content. Isolation of the exosomes was confirmed through transmission electron microscopy. Quantitative PCR was used to assess the miRNA profiles. The effects of let-7c-5p and TAGLN overexpression… More >

Abstract Objective: To explore the role of polycystic kidney and hepatic disease 1-like 1 (PKHD1L1) in lung adenocarcinoma (LUAD). Methods: Bioinformatics tools were utilized to examine the clinical profile of PKHD1L1 and chromobox protein homolog 7 (CBX7) in LUAD. The Cell Counting Kit-8, colony formation, terminal deoxynucleotidyl transferase dUTP nick end labeling, Transwell, and wound-healing assays were carried out to assess the proliferative, apoptotic, invasive, and migrative capacities of the cells. Furthermore, the interrelation between PKHD1L1 and CBX7 was validated using a co-immunoprecipitation assay. A LUAD mice model was constructed by subcutaneous injection of A549 cells.… More >

Abstract Background: Lung adenocarcinoma is a very pervasive histological form of lung cancers, and inhibiting metastasis is crucial for effective treatment. In this investigation, we explored the functional interaction of miR-30a-5p and the putative transcription factor 2 of the homeodomain (PHTF2) in dictating the aggressiveness and metastasis of lung adenocarcinoma. Method: We collected clinical samples to evaluate the expression patterns of miR-30a-5p and PHTF2 in lung adenocarcinoma along with normal tissues. Cellular experiments including cell count kit (CCK)-8 growth assay, apoptosis analysis, migration and invasion examinations were performed to assess the aggressiveness of lung adenocarcinoma cells.… More > Graphic Abstract

Abstract Introduction: Structural maintenance of chromosome 1A (SMC1A) is a crucial compound of the cohesin complex. It has been reported to regulate the epithelial-mesenchymal transition (EMT) process in multiple cancers. Objectives: The present study aims to further clarify the role of SMC1A in cervical cancer. Methods: We analyzed data from four datasets and confirmed that SMC1A showed high expression in cervical cancer samples and was related to poor prognosis of patients with cervical cancer. Cell proliferation of SiHa and C-33A with knockdown of SMC1A was assessed using CCK-8 and colony formation assay. The migration and invasion were… More > Graphic Abstract

Abstract Around one in eight women will be diagnosed with breast cancer at some time. Improved patient outcomes necessitate both early detection and an accurate diagnosis. Histological images are routinely utilized in the process of diagnosing breast cancer. Methods proposed in recent research only focus on classifying breast cancer on specific magnification levels. No study has focused on using a combined dataset with multiple magnification levels to classify breast cancer. A strategy for detecting breast cancer is provided in the context of this investigation. Histopathology image texture data is used with the wavelet transform in this… More >

Abstract Exosomes derived from mesenchymal stem cells (MSC-Exos) are nano-sized extracellular vesicles enriched with bioactive molecules, such as microRNAs, enzymes, cytokines, chemokines, immunomodulatory, trophic, and growth factors. These molecules regulate the survival, phenotype, and function of malignant and tumor-infiltrated immune cells. Due to their nano-size and bilayer lipid envelope, MSC-Exos can easily bypass biological barriers and may serve as drug carriers to deliver chemotherapeutics directly into the tumor cells. Here, we summarize current knowledge regarding molecular mechanisms responsible for MSC-Exos-dependent modulation of tumor progression and discuss insights regarding the therapeutic potential of MSC-Exos in the treatment More > Graphic Abstract

Abstract Late-stage ovarian cancer (OC) has a poor prognosis and a high metastasis rate, but the underlying molecular mechanism is unclear. RNA binding proteins (RBPs) play important roles in posttranscriptional regulation in the contexts of neoplasia and tumor metastasis. In this study, we explored the molecular functions of a canonical RBP, Transformer 2β homolog (TRA2B), in cancer cells. TRA2B knockdown in HeLa cells and subsequent whole-transcriptome RNA sequencing (RNA-seq) analysis revealed the TRA2B-regulated alternative splicing (AS) profile. We disrupted TRA2B expression in epithelial OC cells and performed a series of experiments to confirm the resulting effects… More >
