Abstract Objective: The objective of this study was to determine the level of methotrexate (MTX) toxicity in the intestines of mice and to evaluate the protective effect of probiotics composed of Streptococcus, Bifidobacterium, and Lactobacillus species on intestinal cells during MTX treatment. Methods: Mice were divided into three groups: control, MTX group (received MTX injections), and MTX + probiotics group (received MTX injections along with a diet containing probiotics). Morphological and histological changes, the level of mitochondrial DNA (mtDNA) damage, the level of lipid peroxidation products, and gene expression in the mice’s small intestine were assessed. Results: We… More > Graphic Abstract

Abstract Background: Circular RNAs play an important role in regulating lung adenocarcinoma (LUAD). Bioinformatics analysis identified circ_0015278 as differentially expressed in LUAD. However, the biological mechanism of circ_0015278 in LUAD has not been fully clarified, especially in ferroptosis. Materials and Methods: Bioinformatics analysis was employed to explore the downstream mechanisms of Circ_0015278, subsequently confirmed by luciferase reporter assays. The impact of Circ_0015278 on cell proliferation, migration, invasion, and ferroptosis was investigated through a loss-of-function experiment. A xenotransplantation mouse model elucidated the effect of Circ_0015278 on tumour growth. Results: Circ_0015278 exhibited downregulation in LUAD. It inhibited cell proliferation, More >

Abstract Objective: Transformation from normal cells to malignant cells is the basis for tumorigenesis. While this cell transformation is known to result from aberrant activation or inactivation of associated genes, these genes have not yet been fully identified. In addition, DNAJs, proteins with a J domain, are known to be molecular co-chaperones, but their cellular functions remain largely unexplored. In this context, we here identified DNAJA4, DNAJB11, and DNAJC10 as pro-transforming genes and elucidated their action mechanisms. Methods: Senescence-associated (SA)-β-galactosidase staining and western blotting were used to analyze cellular senescence and protein expression. Soft agar assay was used… More >

Abstract Non-small cell lung cancer (NSCLC) is a malignant tumor with high incidence worldwide. Triptolide (TP), extracted from Tripterygium wilfordii Hook F, exhibits potent broad-spectrum antitumor activity. Although some mechanisms through which TP inhibits NSCLC are well understood, those that involve ribosomal proteins remain yet to be understood. In this study, the transcriptome and proteome were integrated and analyzed. Our data indicated ribosomal protein L4 (RPL4) to be a core hub protein in the protein-protein interaction network. RPL4 is overexpressed in NSCLC tissues and cells. Transfection with siRPL4 or TP treatment alone arrested the cell cycle in More > Graphic Abstract

Abstract The term “undruggable” is to describe molecules that are not targetable or at least hard to target pharmacologically. Unfortunately, some targets with potent oncogenic activity fall into this category, and currently little is known about how to solve this problem, which largely hampered drug research on human cancers. Ras, as one of the most common oncogenes, was previously considered “undruggable”, but in recent years, a few small molecules like Sotorasib (AMG-510) have emerged and proved their targeted anti-cancer effects. Further, myc, as one of the most studied oncogenes, and tp53, being the most common tumor suppressor genes,… More >

Abstract Zinc-finger proteins play different roles in cancer; however, the function of zinc-finger protein ZNF575 in cancer remains unclear. In the present study, we aimed to determine the function and expression of ZNF575 in colorectal cancer. Proliferation assay, colony formation assay, and tumor model in mice were used to investigate the function of ZNF575 after ectopic expression of ZNF575 in colorectal cancer (CRC) cells. RNA sequencing, ChIP, and luciferase assays were used to investigate the mechanism behind ZNF575 regulation of CRC cell growth. The expression of ZNF575 was determined by IHC staining in 150 pairs of… More > Graphic Abstract

Abstract Background: Nano-selenium has been widely used in antiviral and anticancer therapy, and has the advantages of good targeting and low toxicity. For the first time, we combined male reproduction with nano-selenium to investigate its antioxidant effect. This study investigated the protective effect of lentinan functionalized selenium nanoparticles on oxidative stress injury of the hydrogen peroxide (H₂O₂)-induced Leydig cell line, TM3. Methods: The suitable concentration of nano-selenium treatment to promote cell proliferation was also discussed. The concentration of 4 μM could significantly promote the growth of TM3 cells. Oxidative stress damage was caused using an 800 μM concentration… More >

Abstract Background: Kinesin family member 15 (KIF15) is a protein that regulates cell mitosis and plays an important role in the development and progression of several types of human cancers. However, the role of KIF15 in the development of nasopharyngeal cancer (NPC) is still unclear. Methods: The differential expression of KIF15 in NPC and para-carcinoma tissues was evaluated based on data collected from Gene Expression Omnibus (GEO) database and immunohistochemical analysis of clinical specimens collected from a patient cohort. Cell lines 5-8F and CNE-2Z were selected for the construction of KIF15‑knockdown cell models. CCK8 assay, flow cytometry,… More >

Abstract A H₂O₂-induced oxidative stress injury cell model was established to investigate the antioxidant effect of nano-selenium on mouse spermatocyte lines and the regulation mechanism of the expression level and activity of selenium-containing antioxidant enzymes induced by oxidative stress. A safe and effective nano-drug system of functionalized selenium-containing nanoparticles (SeNPs) was developed with lentinan (LNT) (SeNPs@LNT). Mice spermatocyte line GC2-spg cells were treated with SeNPs@LNT (1, 2, 4, 8, 16, 32 μM) for 24–72 h to evaluate the cytotoxicity of selenium. GC2-spg cells were randomly divided into the following groups: control, hydrogen peroxide (H₂O₂), SeNPs@LNT, and H₂O₂+SeNPs@LNT groups.… More >

Abstract Background: MicroRNAs (miRs) are small (19–25 nucleotides), non-protein coding RNAs that regulate gene expression, and thus play essential roles in cell cycle progression. The evidence has demonstrated that the expression of several miRs is dysregulated in human cancer. Methods: The study includes 179 female patients and 58 healthy women Patients were identified as luminal A, B, Her-2/neu, and basal-like, as well as classified into I, II, and III stages. Analysis of the expression fold change of miR-21 and miR-34a with molecular markers, including the oncogene Bcl-2 (B-cell lymphoma 2) and the tumor suppressor genes BRCA1 (breast cancer More >
