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 the G1 phase, induced… 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, are both considered… 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 malignant CRC tissues, followed by… 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 of hydrogen peroxide.… 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 susceptibility gene 1),… 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, wound healing, Transwell and… 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. H₂O₂+SeNPs@LNT group was… More >

Abstract IARS2 encodes mitochondrial isoleucine-tRNA synthetase, which mutation may cause multiple diseases. However, the biological function of IARS2 on acute myeloid leukemia (AML) has not yet been identified. In the present study, qRT-PCR was used to determine the expression of IARS2 in K562, THP1, and HL-60 leukemia cells. Additionally the mRNA levels of IARS2 in CD34 cells and AML cells obtained from patients were detected by qRT-PCR. IARS2-shRNA lentiviral vector was established and used to infect acute myeloid leukemia HL-60 cells. qRT-PCR and Western blot analysis were employed to assess the knockdown effect of IARS2. The proliferation rate and cell cycle… More >

Abstract Hepatocellular carcinoma (HCC) is the third leading cause of cancer-associated mortality worldwide. Although the mechanisms of HCC progression are not well understood, recent studies demonstrated the potential contribution of uric acid transporter SLC2A9 to tumor suppression. However, the roles and underlying mechanisms are still unknown. We aimed to study the roles and mechanisms of SLC2A9 in HCC. The present study showed that SLC2A9 expression was decreased in human HCC tissues and cell lines. In addition, overexpression of SLC2A9 inhibited HCC cell proliferation. SCL2A9 induced HCC cell apoptosis by inhibiting the expression of caspase 3. Our study also revealed that upregulation… More >

Abstract Despite therapeutic advances, the effective treatment for relapsed or refractory diffuse large B-cell lymphoma (DLBCL) remains a major clinical challenge. Evasion of apoptosis through upregulating antiapoptotic B-cell lymphoma-2 (BCL-2) family members and p53 inactivation, and abnormal activation of B-cell receptor signaling pathway are two important pathogenic factors for DLBCL. In this study, our aim is to explore a rational combination of BCL-2 inhibitor plus Bruton’s tyrosine kinase (BTK) blockade or p53 activation for treating DLBCL with the above characteristics. We demonstrated that a novel BCL-2 selective inhibitor APG-2575 effectively suppressed DLBCL with BCL-2 high expression via activating the mitochondrial apoptosis… More >
