    Abstract Objectives: While programmed cell death 1 (PD-1) inhibitors have improved cancer treatment, the function and mechanisms of programmed cell death ligand 1 (PD-L1), particularly when expressed by cancer cells, remain unclear. This study aims to explore the role of PD-L1 within breast cancer cells and identify key targets for future immunotherapy. Methods: RNA-seq was performed on breast cancer cells with silenced PD-L1 to screen for differentially expressed genes, followed by bioinformatics analysis. Clinical specimens from breast cancer patients undergoing primary surgery without preoperative treatment were collected, along with in vitro analysis to validate the potential mechanism.

    EGR1 inhibits clear cell renal cell carcinoma proliferation and metastasis via the MAPK15 pathway

    NAIXIONG PENG, YUEFENG CAI, DONG CHEN, LING DENG, ZEJIAN ZHANG, WEI LI*

    Oncology Research, Vol.33, No.2, pp. 347-356, 2025, DOI:10.32604/or.2024.056039 - 16 January 2025

    Abstract Background: Clear cell renal carcinoma (ccRCC), the leading histological subtype of RCC, lacks any targeted therapy options. Although some studies have shown that early growth response factor 1 (EGR1) has a significant role in cancer development and progression, its role and underlying mechanisms in ccRCC remain poorly understood. Methods: The Cancer Genome Atlas (TCGA) database was utilized to examine the expression of EGR1 in ccRCC. The expression of EGR1 in 55 ccRCC tissues was evaluated using immunohistochemistry. The link between EGR1 expression and clinicopathological variables was examined through an analysis. Gain-of-function assays were employed to… More >

    Unraveling the RAGE axis in pulmonary disorders: Mechanisms and therapeutical potential

    SHUOCHEN PANG1, TAO JIA1,*, ZIFENG YANG2,*

    BIOCELL, Vol.48, No.12, pp. 1721-1734, 2024, DOI:10.32604/biocell.2024.055753 - 30 December 2024

    Abstract The Receptor for Advanced Glycation End Products (RAGE) is a multiligand receptor of the immunoglobulin superfamily, notably highly expressed in the lungs. Its interaction with a variety of ligands, including advanced glycation end products (AGEs), S100 proteins, and high mobility group box 1 (HMGB1), activates multiple signaling pathways that are pivotal in the pathogenesis of numerous pulmonary diseases and comorbidities. However, comprehensive reviews on the role of ligands-RAGE signaling in specific lung diseases are rare. This review aims to elucidate the mechanisms by which RAGE-mediated signaling pathways either provide protective or pathogenic effects in pulmonary More >

    hsa-miR-181a-5p inhibits glioblastoma development via the MAPK pathway: in-silico and in-vitro study

    MAHDI ABDOLI SHADBAD1, BEHZAD BARADARAN2,*

    Oncology Research, Vol.32, No.12, pp. 1949-1958, 2024, DOI:10.32604/or.2024.051569 - 13 November 2024

    Abstract Background: Glioblastoma remains a highly invasive primary brain malignancy with an undesirable prognosis. Growing evidence has shed light on the importance of microRNAs (miRs), as small non-coding RNAs, in tumor development and progression. The present study leverages the in-silico and in-vitro techniques to investigate the significance of hsa-miR-181a-5p and the underlying hsa-miR-181a-5p-meidated signaling pathway in glioblastoma development. Methods: Bioinformatic studies were performed on GSE158284, GSE108474 (REMBRANDT study), TCGA-GTEx, CCLE, GeneMANIA, Reactome, WikiPathways, KEGG, miRDB, and microT-CDS to identify the significance of hsa-miR-181a-5p and its underlying target. Afterward, the U373 cell line was selected and transfected with… More >

    MPPa-PDT induced apoptosis and autophagy through JNK and p38 MAPK signaling pathways in A549 cells

    PINGHUA TU, SHANSHAN WANG, KELAN DENG, XINJUN LI, ZHANLING WU*

    BIOCELL, Vol.48, No.11, pp. 1603-1612, 2024, DOI:10.32604/biocell.2024.054364 - 07 November 2024

    Abstract Objectives: The antitumor effects of pyropheophorbide-α methyl ester-mediated photodynamic therapy (MPPa-PDT) were observed in several cancers. The objective of this investigation was to examine the antineoplastic efficacy of MPPa-PDT acting on lung carcinoma A549 cells and further elaborate mechanisms. Methods: The viability of A549 cells was examined with cell counting kit-8 after MPPa-PDT disposal. Hoechst 33342 staining, monodansylcadaverine (MDC) staining, and transmission electron microscopy were employed to observe apoptotic bodies and autophagic vesicles. Flow cytometry with Annexin V/propidium iodide (PI) labeling objectively assessed cell death. The expression of associated proteins, including Caspase-3, Beclin-1, LC-3II, and More > Graphic Abstract

    Revealing the role of honokiol in human glioma cells by RNA-seq analysis

    YUNBAO GUO1,#, XU LIU1,#, QI XU2, XIAOTONG ZHOU3, JIAWEI LIU3, YANYAN XU2, YAN LU2,*, HAIYAN LIU2,*

    BIOCELL, Vol.48, No.6, pp. 945-958, 2024, DOI:10.32604/biocell.2024.049748 - 10 June 2024

    Abstract Background: Glioma is a kind of tumor that easily deteriorates and originates from glial cells in nerve tissue. Honokiol is a bisphenol compound that is an essential monomeric compound extracted from the roots and bark of Magnoliaceae plants. It also has anti-infection, antitumor, and immunomodulatory effects. In this study, we found that honokiol induces cell apoptosis in the human glioma cell lines U87-MG and U251-MG. However, the mechanism through which honokiol regulates glioma cell apoptosis is still unknown. Methods: We performed RNA-seq analysis of U251-MG cells treated with honokiol and control cells. Protein-protein interaction (PPI)… More > Graphic Abstract

    YI HU1,#, ZHONGYANG REN2,#, ZHENGZHONG ZHAO1, YONGJIA HUANG3, WANTING HUANG3, JIE LIU3,*, LING DING3,*

    BIOCELL, Vol.48, No.5, pp. 745-758, 2024, DOI:10.32604/biocell.2024.049140 - 06 May 2024

    Abstract Background: Acute pancreatitis (AP), known for its rapid onset and significant incidence and mortality rates, presents a clinical challenge due to the limited availability of effective treatments and preventive measures. Anemarsaponin B (ASB) has emerged as a potential therapeutic agent, demonstrating capabilities in reducing immune inflammation, positioning it as a promising candidate for AP treatment. Methods: We investigated the effects of ASB on AP in mice, induced by caerulein and lipopolysaccharide (LPS). Peripheral blood samples were collected 24 h post-induction with caerulein to assess of key biomarkers including lipase, amylase, TNF-α, IL-1β, IL-6, SOD, and… More >

    BIOCELL, Vol.48, No.5, pp. 771-792, 2024, DOI:10.32604/biocell.2024.048878 - 06 May 2024

    Abstract Background: Ferroptosis, a lipid peroxidation-mediated programmed cell death, is closely linked to tumor development, including prostate cancer (PCa). Despite established connections between ferroptosis and PCa, a comprehensive investigation is essential for understanding its impact on patient prognosis. Methods: A risk model incorporating four ferroptosis-related genes was developed and validated. Elevated risk scores correlated with an increased likelihood of biochemical recurrence (BCR), diminished immune infiltration, and adverse clinicopathological characteristics. To corroborate these results, we performed validation analyses utilizing datasets from both the Cancer Genome Atlas Cohort (TCGA) and the Gene Expression Synthesis Cohort (GEO). Moreover, we conducted… More >
