Abstract Colorectal cancer (CRC) stands among the top prevalent cancers worldwide and holds a prominent position as a major contributor to cancer-related mortality globally. Absent in melanoma 2 (AIM2), a constituent of the interferon-inducible hematopoietic interferon-inducible nuclear antigens with 200 amino acid repeats protein family, contributes to both cancer progression and inflammasome activation. Despite this understanding, the precise biological functions and molecular mechanisms governed by AIM2 in CRC remain elusive. Consequently, this study endeavors to assess AIM2’s expression levels, explore its potential antitumor effects, elucidate associated cancer-related processes, and decipher the underlying signaling pathways in CRC. Our findings showed a reduced… More > Graphic Abstract

Abstract Genetic information is transcribed from genomic DNA to mRNA, which is then translated into three-dimensional proteins. mRNAs can undergo various post-transcriptional modifications, including RNA editing that alters mRNA sequences, ultimately affecting protein function. In this study, RNA editing was identified at the 499th base (c.499) of human vaccinia-related kinase 2 (VRK2). This RNA editing changes the amino acid in the catalytic domain of VRK2 from isoleucine (with adenine base) to valine (with guanine base). Isoleucine-containing VRK2 has higher kinase activity than the valine-containing VRK2, which leads to an increase in tumor cell proliferation. Earlier we reported that VRK2 directly interacts… More > Graphic Abstract

Abstract Background: This study aimed to explore the expression, function, and molecular mechanism of ANXA8, the gene for annexin 8, in cervical cancer. Methods: The gene expression of the ANX family members in cervical cancer tissues was classified via The Cancer Genome Atlas (TCGA) database. The expression of ANXA8 in paracancerous tissues, cervical cancer tissues, and cell lines was identified by fluorescence quantitative polymerase chain reaction (PCR) and immunohistochemistry. The effects of ANXA8 knockdown on the cellular growth and cell invasion of cervical cancer were examined by MTT, clone-formation assay, scratch test, and Transwell assay. The effect of ANXA8 knockdown on… More >

Abstract Objective: This investigation aimed to unveil new prospective diagnosis-related biomarkers together with treatment targets against glioblastoma. Methods: The expression levels of long non-coding RNA (lncRNA) DPP10-AS1 were assessed using real-time quantitative polymerase chain reaction (RT-qPCR) within both the patient tissue specimens and glioblastoma cell lines. The relationship between lncRNA DPP10-AS1 expression in glioblastoma and patient prognosis was investigated. Cell Counting Kit-8 (CCK-8), transwell, and clonogenic experiments were utilized to assess tumor cells’ proliferation, invasiveness, and migratory potentials after lncRNA DPP10-AS1 expression was up or down-regulated. Using an online bioinformatics prediction tool, the intracellular localization of lncRNA DPP10-AS1 and its target… More >

Abstract Background: Glioma is the most common primary brain tumor. Exploration of new tumorigenesis mechanism of glioma is critical to determine more effective treatment targets as well as to develop effective prognosis methods that can enhance the treatment efficacy. We previously demonstrated that the deubiquitinase biquitin carboxyl-terminal hydrolase L5 (UCHL5) was downregulated in human glioma. However, the effect and mechanism of UCHL5 on the proliferation of glioma cells remains unknown. Methods: Transfection of siRNA was used to knockdown the expression of UCHL5 in U251 cells. The 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay, Edu assay, and colony formation assay were employed to… More > Graphic Abstract

Abstract Background: Nasopharyngeal carcinoma (NPC) is one of the most prevalent cancers in Southeast Asia. Sirtuin 2 (SIRT2) is a member of the NAD+-dependent deacetylase family and has been shown to play important roles in numerous biological processes. However, Its function in NPC remains uncertain. The primary aim of this study is to clarify the role of SIRT2 in NPC. Methods: In this research, we examined the effect of SIRT2 silencing on NPC cell proliferation and colony formation using vitro NPC cell lines. Co-immunoprecipitation and mass spectrometry was applied to identify SIRT2-interacting proteins in NPC cells. Results: In comparison to nasopharyngeal… 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 estimated by wound healing… More > Graphic Abstract

Abstract Hepatocellular carcinoma (HCC), a common malignancy worldwide, still lacks effective clinical treatment. The study aimed to investigate the oncogenes that affect the progression of HCC and their possible mechanisms. In our study, we initially confirmed a higher level of PRDX2 in the bile of HCC patients compared to those with choledocholithiasis by 2-DE, LC-MS, and ELISA. Subsequently, we demonstrated the high expression of peroxiredoxin 2 (PRDX2) in HCC based on the TCGA database and clinical sample analysis. Furthermore, PRDX2 overexpression enhanced the viability of HCC cells. And PRDX2 silencing induced senescence of HCC cells. In vivo, knockdown of PRDX2 significantly… More >

Abstract Hepatocellular carcinoma (HCC) is the leading cause of cancer death worldwide; nevertheless, current therapeutic options are limited or ineffective for many patients. Therefore, elucidation of molecular mechanisms in HCC biology could yield important insights for the intervention of novel therapies. Recently, various studies have reported dysregulation of long non-coding RNAs (lncRNAs) in the initiation and progression of HCC, including H19; however, the biological function of H19 in HCC remains unclear. Here, we show that knockdown of H19 disrupted HCC cell growth, impaired the G1-to-S phase transition, and promoted apoptosis, while overexpression of H19 yielded the opposite results. Screening for expression… More > Graphic Abstract

Abstract Hepatocellular carcinoma (HCC) is a common malignancy that is driven by multiple genes and pathways. The aim of this study was to investigate the role and specific mechanism of the actin-interacting protein zyxin (ZYX) in HCC. We found that the expression of ZYX was significantly higher in HCC tissues compared to that in normal liver tissues. In addition, overexpression of ZYX in hepatoma cell lines (PLC/PRF/5, HCCLM3) enhanced their proliferation, migration and invasion, whereas ZYX knockdown had the opposite effects (SK HEP-1, Huh-7). Furthermore, the change in the expression levels of ZYX also altered that of proteins related to cell… More >
