    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 >

    Abstract Background: Platinum chemotherapy (CT) remains the backbone of systemic therapy for patients with small-cell lung cancer (SCLC). The nucleotide excision repair (NER) pathway plays a central role in the repair of the DNA damage exerted by platinum agents. Alteration in this repair mechanism may affect patients’ survival. Materials and Methods: We conducted a retrospective analysis of data from 38 patients with extensive disease (ED)-SCLC who underwent platinum-CT at the Clinical Oncology Unit, Careggi University Hospital, Florence (Italy), from 2015 to 2020. mRNA expression analysis and single nucleotide polymorphism (SNP) characterization of three NER pathway genes—namely ERCC1, ERCC2,… More >

    RNF26 up-regulates PD-L1 to regulate the cancer immune response in ccRCC

    WEIGANG REN1,#, JING LI2,#, RUIJIANG ZENG3,4, LIANG ZHU3,4,*

    BIOCELL, Vol.48, No.9, pp. 1323-1330, 2024, DOI:10.32604/biocell.2024.051747 - 04 September 2024

    Abstract Background: Clear cell renal cell carcinoma (ccRCC) stands as the most prevalent form of kidney cancer, accounting for a significant proportion of malignancies affecting the kidneys. ccRCC is well known as a type of tumour with immunogenicity. Immune checkpoint inhibitors (ICIs) aim to enhance the anticancer immune response in ccRCC by blocking programmed cell death 1 ligand 1/programmed death 1 (PD-L1/PD-1) pathways. In a previous study, we showed that RING finger protein 26 (RNF26) degrades chromobox 7 (CBX7) to activate the tumor necrosis factor (TNF) in ccRCC. Methods: We analyzed The Cancer Genome Atlas (TCGA)… More > Graphic Abstract

    KAIWEN TIAN#, HANZHONG CHEN#, QIANQIAN WANG, FENGLIAN JIANG, CHUNXIANG FENG, TENG LI, XIAOYONG PU, YANLIN TANG*, JIUMIN LIU*

    BIOCELL, Vol.48, No.5, pp. 817-834, 2024, DOI:10.32604/biocell.2024.048737 - 06 May 2024

    Abstract Background: The incidence of clear cell renal cell carcinoma (ccRCC) is globally high; however, despite the introduction of innovative drug therapies, there remains a lack of effective biomarkers for evaluating treatment response. Recently, Caspase recruiting domain-containing protein 11 (CARD11) has garnered attention due to its significant association with tumor development and the immune system. Methods: The expression of CARD11 mRNA and protein in ccRCC were analyzed by public database and immunohistochemistry. The focus of this study is on the epigenomic modifications of CARD11, its expression of ccRCC immunophenotype, and its correlation with response to immunotherapy… More > Graphic Abstract

    Abstract As a common tumor of the urinary system, the morbidity and mortality related to renal carcinoma, are increasing annually. Clear cell renal cell carcinoma (CCRCC) is the most common subtype of renal cell carcinoma, accounting for approximately 75% of the total number of patients with renal cell carcinoma. Currently, the clinical treatment of ccRCC involves targeted therapy, immunotherapy, and a combination of the two. In immunotherapy, PD-1/PD-L1 blocking of activated T cells to kill cancer cells is the most common treatment. However, as treatment progresses, some patients gradually develop resistance to immunotherapy. Meanwhile, other patients More > Graphic Abstract

    Abstract The field of object tracking has recently made significant progress. Particularly, the performance results in both deep learning and correlation filters, based trackers achieved effective tracking performance. Moreover, there are still some difficulties with object tracking for example illumination and deformation (DEF). The precision and accuracy of tracking algorithms suffer from the effects of such occurrences. For this situation, finding a solution is important. This research proposes a new tracking algorithm to handle this problem. The features are extracted by using Modified LeNet-5, and the precision and accuracy are improved by developing the Real-Time Cross-modality… More >

    Abstract Background: Six2, a transcription factor, exerts an oncogenic role in clear cell renal cell carcinoma (ccRCC). Increased Six2 expression could enhance cancer metastasis. However, the regulatory mechanism of Six2 in promoting metastasis remains unclear. The purpose of this study is to analyze the regulatory pattern of Six2 and the potential role of Six2 in the tumor immune microenvironment. Materials and Methods: Firstly, transcriptional data in TCGA-KIRC cohorts was used to analyze the relationship between Six2 expression and clinical information. Secondly, we detect the association between Six2 and the tumor immune microenvironment in ccRCC. Then, we analyzed Six2-related… More >

    Leader-Follower UAV Formation Model Based on R5DOS-Intersection Model

    Jian Li1,3, Weijian Zhang1, Yating Hu1,4, Xiaoguang Li2,*, Zhun Wang1

    CMC-Computers, Materials & Continua, Vol.69, No.2, pp. 2493-2511, 2021, DOI:10.32604/cmc.2021.018743 - 21 July 2021

    Abstract This paper proposes a formation of multiple unmanned aerial vehicles (UAVs) based on the R5DOS (RCC-5 and orientation direction) intersection model. After improving the R5DOS-intersection model, we evenly arranged 16 UAVs in 16 spatial regions. Compared with those of the rectangular formation model and the grid formation model, the communication costs, time costs, and energy costs of the R5DOS model formation were effectively reduced. At the same time, the operation time of UAV formation was significantly enhanced. The leader-follower method can enhance the robustness of the UAV formation and ensure the integrity of communication during… More >

    Xingliang Feng*1, Meng Zhang*†1, Jialin Meng*, Yongqiang Wang, Yi Liu*, Chaozhao Liang*, Song Fan*

    Oncology Research, Vol.28, No.3, pp. 285-297, 2020, DOI:10.3727/096504020X15791676105394

    Abstract We aimed to investigate the potential mechanisms of progression and identify novel prognosis-related biomarkers for papillary renal cell carcinoma (PRCC) patients. The related data were derived from The Cancer Genome Atlas (TCGA) and then analyzed by weighted gene coexpression network analysis (WGCNA). The correlation between each module and the clinical traits were analyzed by Pearson’s correlation analysis. Pathway analysis was conducted to reveal potential mechanisms. Hub genes within each module were screened by intramodule analysis, and visualized by Cytoscape software. Furthermore, important hub genes were validated in an external dataset and clinical samples.

    The AKT/GSK3β-Mediated Slug Expression Contributes to Oxaliplatin Resistance in Colorectal Cancer via Upregulation of ERCC1

    Wei Wei*1, Xiao-Dong Ma†1, Guan-Min Jiang, Bin Shi§, Wen Zhong, Chun-Lei Sun§, Liang Zhao*, Yan-Jiao Hou*, Hao Wang*

    Oncology Research, Vol.28, No.4, pp. 423-438, 2020, DOI:10.3727/096504020X15877284857868

    Abstract Although oxaliplatin serves as one of the first-line drugs prescribed for treating colorectal cancer (CRC), the therapeutic effect is disappointing due to drug resistance. So far, the molecular mechanisms mediating oxaliplatin resistance remain unclear. In this study, we found the chemoresistance in oxaliplatin-resistant HCT116 cells (HCT116/OXA) was mediated by the upregulation of ERCC1 expression. In addition, the acquisition of resistance induced epithelial–mesenchymal transition (EMT) as well as the Slug overexpression. On the contrary, Slug silencing reversed the EMT phenotype, decreased ERCC1 expression, and ameliorated drug resistance. Further mechanistical studies revealed the enhanced Slug expression resulted More >
