    Oncologie, Vol.23, No.1, pp. 47-59, 2021, DOI: 10.32604/Oncologie.2021.15525
    Abstract Immunotherapy for digestive cancers is booming and for the first time an immune checkpoint inhibitor has been granted marketing authorization for the treatment of digestive cancer. In order to better understand the mecanism of action of these treatments, their adverse events and the escape mecansim, it is necessary to know the fundamentals of cancer immunology. The innate and adaptive immune system allows the elimination of cancer cells by direct non-specific cytotoxicity (Natural Killer cells), by the development of an adaptive cell-mediated response (dendritic cells becoming antigen presenting cells, allowing the differentiation of lymphocytes naive in CD4 and CD8 T lymphocytes)… More >


    TUG1 Indicate Unfavorable Prognosis of Gastric Cancer for Promoting Proliferation, Migration and Multidrug Resistance

    Yuan Liu1,2,#, Yun Jia3, Bing Zhang2, Anwen Liu1,*
    Oncologie, Vol.23, No.1, pp. 61-72, 2021, DOI:10.32604/Oncologie.2021.015906
    Abstract Gastric cancer (GC) is the most common digestive system malignant tumor and second most common cause of cancer-related death. Even for the early gastric cancer, after radical operation, perioperative and postoperative chemotherapy the recurrence and metastasis are also high. 5-year overall survival of all GC patients is only 10–15%. Chemo-resistance still poses a major obstacle to successful treatment of GC. The aberrant expression of TUG1 (Taurine Upregulated Gene 1) was closely related to chemo-resistance and metastasis in many cancers. Here we over-expressed TUG1 in GC cell line SGC-7901 and MGC-803. We compared the migration ability and sensitivity of cisplatin (CDDP),… More >

    Oncologie, Vol.23, No.1, pp. 73-88, 2021, DOI:10.32604/Oncologie.2021.015154
    Abstract Cervical cancer is a cell disease in the cervix that develops out of control in the female body. The cervix links the vagina (birth canal) with the upper section of the uterus, which can only be found in the female body. This is the second leading cause of death among women around the world. However, cervical cancer is currently one of the most preventable cancers if early detection is identified. The effect of unidentified cancer may increase the risk of death when the cell disease spreads to other parts of the female anatomy (metastasize). The Papanicolaou test is a cervical… More >

    Comparison of Amino Acid Metabolisms in Normal Prostate (PNT-1A) and Cancer Cells (PC-3)

    Erkan Arslan1,*, Ismail Koyuncu2
    Oncologie, Vol.23, No.1, pp. 105-117, 2021, DOI:10.32604/Oncologie.2021.014764
    Abstract Prostate cancer is the second most common cancer in men. Prostate-specific antigen (PSA) levels, commonly used in the diagnosis of prostate cancer, are increased in both malign and benign conditions, such as prostate hyperplasia (BPH) and prostatitis. Thus, more specific markers are urgently needed to discriminate between prostate cancer and benign diseases of the prostate. The purpose of this study is to examine both the intracellular and extracellular free amino acid profiles of metastatic prostate cancer cells (PC-3), normal prostate cells (PNT-1A), and metabolic changes (e.g., pH). In this study, cancer and normal cells were incubated in the appropriate medium.… More >

    Oncologie, Vol.23, No.1, pp. 159-171, 2021, DOI:10.32604/Oncologie.2021.012489
    Abstract Breast cancer is one of malignant severe diseases that cause cancer death in women. Although research about the pathogenesis and studies about treatment mechanisms in breast cancer have become clear focuses, we have no clear conclusion yet. Therefore, this research is based on a modular approach to explore key factors and molecular mechanisms that affect breast cancer metastasis. First of all, it is necessary to download breast cancer-related data on the GEO database, and we analyzed the difference between primary tumors and metastatic lesions to obtain differential gene expression profiles. On this basis, a series of bioinformatics analyses were performed… More >
