    Abstract Introduction: Chemokine-like factor 1 (CKLF1) is a chemokine that is overexpressed in several diseases. Our previous findings revealed a significant increase in CKLF1 expression in the ischemic brain, suggesting its potential as a therapeutic target for ischemic stroke. Methods: In this study, we examined the expression dynamics of CKLF1 in both in vivo and in vitro models of ischemic cardiac injury. Myocardial infarction (MI) was induced in vivo by ligation of the left anterior descending artery (LAD) of the rat heart. The levels of CKLF1, Creatine Kinase MB Isoenzyme (CK-MB), and Lactate dehydrogenase (LDH) in the serum were… More > Graphic Abstract

    OPA3 overexpression modulates lipid droplet production and sensitizes colorectal cancer cells to bevacizumab treatment

    HONGBIAO WU*, DONGFANG LIU

    BIOCELL, Vol.48, No.6, pp. 971-980, 2024, DOI:10.32604/biocell.2024.049466

    Abstract Background: Colorectal cancer (CRC) represents a substantial risk to public health. Bevacizumab, the first US FDA-approved antiangiogenic drug (AAD) for human CRC treatment, faces resistance in patients. The role of lipid metabolism, particularly through OPA3-regulated lipid droplet production, in overcoming this resistance is under investigation. Methods: The protein expression pattern of OPA3 in CRC primary/normal tissues was evaluated by bioinformatics analysis. OPA3-overexpressed SW-480 and HCT-116 cell lines were established, and bevacizumab resistance and OPA3 effects on cell malignancy were examined. OPA3 protein/mRNA expression and lipid droplet-related genes were measured with Western blot and qRT-PCR. OPA3… More > Graphic Abstract

    Su-Hoon Lee, Suh-Kyung Hyun, Hak-Bong Kim, Chi-Dug Kang, Sun-Hee Kim

    Oncology Research, Vol.24, No.6, pp. 495-509, 2016, DOI:10.3727/096504016X14685034103950

    Abstract Hepatocellular carcinoma (HCC) is one of the most common malignancies, with a poor prognosis and high recurrence rate. In the present study, we identified CD133, one of the markers of cancer stem cells, as a novel molecular target of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). In four human HCC cell lines established from primary HCC tumors, we found that CD133-high human liver cancer stem-like cells (CD133hi) derived from the SNU-475 cell line were highly susceptible to TRAIL compared to other HCC cell lines with a small population of CD133. CD133hi SNU-475 cells showed upregulation of TRAIL… More >

    Oncology Research, Vol.24, No.5, pp. 305-313, 2016, DOI:10.3727/096504016X14666990347437

    Abstract Tumor necrosis factor-a (TNF-a)-induced protein 8-like 2 (TNFAIP8L2, TIPE2) is involved in the invasion and metastasis of human tumors. However, the functional role of TIPE2 in prostate cancer remains unclear. In the present study, we explored the role of TIPE2 in prostate cancer and cancer progression including the molecular mechanism that drives TIPE2-mediated oncogenesis. Our results showed that TIPE2 was lowly expressed in human prostate cancer tissues and cell lines. In addition, restored TIPE2 obviously inhibits proliferation in prostate cancer cells. TIPE2 overexpression also suppresses the epithelial–mesenchymal transition (EMT) process and migration/invasion in prostate cancer More >

    Oncology Research, Vol.24, No.4, pp. 233-238, 2016, DOI:10.3727/096504016X14648701447977

    Abstract Triple-negative breast cancer (TNBC) is associated with high recurrence rates of metastasis and death. miR-509 has been reported to be a tumor suppressor in many cancers, but its effect in TNBC has not yet been identified. In this article, we explored the effects of miR-509 on the malignant phenotype of TNBC cells, including proliferation, apoptosis, migration, and invasion. We transiently transfected TNBC cells, Hs578T, with miR-509 mimic. Upon transfection, the expression of miR-509 was upregulated about 50-fold compared with cells transfected with scramble mimic. Overexpression of miR-509 inhibited cell proliferation, induced cell apoptosis, and suppressed More >

    Wenliang Tan*†1, Sicong Zhu*†1, Jun Cao*†, Lei Zhang*†, Wenda Li*†, Kairui Liu*†, Jinyi Zhong, Changzhen Shang*†, Yajin Chen*†

    Oncology Research, Vol.25, No.9, pp. 1543-1553, 2017, DOI:10.3727/096504017X14886444100783

    Abstract Sorafenib has been globally approved as the standard treatment for patients with advanced hepatocellular carcinoma (HCC). However, the response rate of HCC patients to sorafenib is limited because of tumor recurrence and metastasis. Therefore, seeking combined therapeutic strategies with sorafenib is necessary to improve the antitumor efficiency. Here we demonstrated that expression of MMP-2 is positively correlated with the migration ability of HCC cells. Cells with a higher MMP-2 expression (SK-HEP-1 cells) were less sensitive to sorafenib than those with lower MMP-2 expression (HepG2 cells). Cotreatment of cells with SB-3CT and sorafenib more strongly inhibited… More >

    Oncology Research, Vol.25, No.8, pp. 1317-1327, 2017, DOI:10.3727/096504017X14874323871217

    Abstract Increasing studies have suggested that microRNAs (miRNAs) are involved in the development of gliomas. MicroRNA-216a has been reported to be a tumor-associated miRNA in many types of cancer, either as an oncogene or as a tumor suppressor. However, little is known about the function of miR-216a in gliomas. The present study was designed to explore the potential role of miR-216a in gliomas. We found that miR-216a was significantly decreased in glioma tissues and cell lines. Overexpression of miR-216a significantly suppressed the proliferation, migration, and invasion of glioma cells.
