Abstract Objectives: Proteasomes, multi-subunit proteases, are key actors of cellular protein catabolism and a number of regulatory processes. The detection of subtle proteasome functioning in tumors may contribute to our understanding of the mechanisms of cancer development. The current study aimed to identify the role of low molecular mass protein 2 (LMP2), a proteasome immune subunit, in the development of mouse colon 26 (C26) adenocarcinoma. Methods: The functions of the LMP2 subunit in tumor development in Balb/c mice were studied using its irreversible inhibitor KZR-504. LMP2 activity was detected by the hydrolysis of the fluorogenic substrate… More >

Abstract Background: The growth of the B-cell lymphoma subtype, Hodgkin lymphoma (HL), is associated with increased autophagy. A mycobacterial antigen, Ag85, has been reported to inhibit cell autophagy under a variety of conditions. Whether Ag85 could inhibit autophagy in HL is unknown. Methods: Lymph node samples from patients with HL and healthy controls were collected to assess proliferation and autophagy. The human HL cell line, L-428, was cultured and subjected to Ag85B treatment. Autophagy in L-428 cells was evaluated through western blotting analysis, immunohistochemistry, and transmission electron microscopy. Apoptosis in these cells was measured using flow… More >

Abstract Z-DNA binding protein 1 (ZBP1) has emerged as a critical player in cancer biology, functioning as a cytosolic nucleic acid sensor that triggers PANoptosis, a form of programmed cell death that integrates pyroptosis, apoptosis, and necroptosis. Although ZBP1 was initially recognized for its role in antiviral defense, recent research has highlighted its importance in the tumor microenvironment (TME), where it is essential for suppressing tumor growth and proliferation. This review explores the multifaceted role of ZBP1 in various cancer types, emphasizing its ability to detect Z-nucleic acids and double-stranded RNAs, leading to the initiation of… 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 Multiple myeloma (MM) is a plasma cell malignancy and remains incurable as it lacks effective curative approaches; thus, novel therapeutic strategies are desperately needed. The study aimed to explore the therapeutic role of dihydromyricetin (DHM) in MM and explore its mechanisms. Human MM and normal plasma samples, human MM cell lines, and normal plasma cells were used for in vitro experiments. Cell counting kit-8 (CCK-8), flow cytometry, and trans-well assays were performed for the assessment of cell viability, apoptosis, migration, and invasion, respectively. Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to assess the mRNA expression… More > Graphic Abstract

Abstract It has been shown that the high expression of human epididymis protein 4 (HE4) in most lung cancers is related to the poor prognosis of patients, but the mechanism of pathological transformation of HE4 in lung cancer is still unclear. The current study is expected to clarify the function and mechanism of HE4 in the occurrence and metastasis of lung adenocarcinoma (LUAD). Immunoblotting evaluated HE4 expression in lung cancer cell lines and biopsies, and through analysis of The Cancer Genome Atlas (TCGA) dataset. Frequent HE4 overexpression was demonstrated in LUAD, but not in lung squamous… More >

Abstract The high mortality rate associated with gastric cancer (GC) has resulted in an urgent need to identify novel therapeutic targets for GC. This study aimed to investigate whether GAIP interacting protein, C terminus 1 (GIPC1) represents a therapeutic target and its regulating mechanism in GC. GIPC1 expression was elevated in GC tissues, liver metastasis tissues, and lymph node metastases. GIPC1 knockdown or GIPC1 blocking peptide blocked the platelet-derived growth factor receptor (PDGFR)/PI3K/AKT signaling pathway, and inhibited the proliferation and migration of GC cells. Conversely, GIPC1 overexpression markedly activated the PDGFR/PI3K/AKT signaling pathway, and promoted GC More > Graphic Abstract

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… More > Graphic Abstract

Abstract Tet methylcytosine dioxygenase 2 (TET2) acts as an antioncogene that is investigated in different cancers. But the effects of TET2 in renal cell cancer (RCC) is still known little. Here, quantitative real-time PCR (qRT-PCR), Western blot, and immunofluorescence were performed to exam gene and protein expression. Cell proliferation was measured using Cell Counting Kit-8 (CCK-8). Transwell assay was performed to detect cell metastasis viability. Flow cytometry was performed to analyze the cell cycle and cell apoptosis. The effects of TET2 on RCC growth in vivo was analyzed using a mouse xenograft model.We found that TET2 More >

Abstract Anaplastic thyroid carcinoma (ATC) is resistant to standard therapies and has no effective treatment. Eukaryotic translation initiation factor 5A2 (EIF5A2) has shown to be upregulated in many malignant tumors and proposed to be a critical gene involved in tumor metastasis. In this study, we aimed to investigate the expression status of EIF5A2 in human ATC tissues and to study the role and mechanisms of EIF5A2 in ATC tumorigenesis in vitro and in vivo. Expression of EIF5A2 protein was analyzed in paraffin-embedded human ATC tissues and adjacent nontumorous tissues (ANCT) (n = 24) by immunochemistry. Expressions… More >
