    MicroRNA-1284 Inhibits Cell Viability and Induces Apoptosis of Ovarian Cancer Cell Line OVCAR3

    Changqing Pan, Dan Wang, Yao Zhang, Wenliang Yu

    Oncology Research, Vol.24, No.6, pp. 429-435, 2016, DOI:10.3727/096504016X14685034103518

    Abstract Ovarian cancer is a malignancy with high mortality among women. Multiple reports show that microRNAs (miRs) act as regulators in ovarian cancer inhibition, while the role of miR-1284 in ovarian cancer is still unknown. This study aimed to investigate the effects of miR-1284 on ovarian cancer cells. Human ovarian cancer cell line OVCAR3 was cultured and transfected with miR-1284 mimics, inhibitors, or control. Viability and apoptosis of transfected cells were then determined by MTT assay, BrdU assay, and flow cytometry. Expression changes of p27, p21, and PI3K/Akt pathway-related proteins were measured by Western blot. Results More >

    Gang Yuan, Jingzi Quan, Dongfang Dong, Qunying Wang

    Oncology Research, Vol.26, No.7, pp. 1037-1046, 2018, DOI:10.3727/096504017X15144748428127

    Abstract Gastric carcinoma (GC) remains the second leading cause of cancer-related deaths worldwide. Good biomarkers are of paramount importance for GC therapy. This study aimed to assess the role of long noncoding RNA (lncRNA) CAT104 in GC. We found that CAT104 was highly expressed in human GC NCI-N87, SGC7901, BGC823, BGC803, and AGS cells. Suppression of CAT104 decreased NCI-N87 cell viability, migration, and invasion, but promoted apoptosis. CAT104 knockdown enhanced the expression of microRNA- 381 (miR-381) expression in NCI-N87 cells. miR-381 participated in the regulatory effects of CAT104 on NCI-N87 cell viability, migration, invasion, and apoptosis.

    Oncology Research, Vol.26, No.4, pp. 655-664, 2018, DOI:10.3727/096504017X15119525209765

    Abstract Although cisplatin has been shown to be an integral part of chemotherapy regimen in osteosarcoma (OS) treatment, toxicity issues and chemoresistance have hindered therapeutic development for OS. Exploring novel combination therapy methods is needed to circumvent the limitations of cisplatin alone. The proteasome inhibitor MG132 has shown antitumor effects in many solid tumors. However, little is known about its effects in combination with cisplatin in OS cells. In this study, we examined the effects of MG132 in combination with cisplatin in human OS cells (MG-63 and HOS). MG132 and cisplatin were applied to OS cells,… More >

    Hui Li*1, Huicheng Chen†1, Haibin Wang, Yilong Dong, Min Yin, Liang Zhang§, Jia Wei*

    Oncology Research, Vol.26, No.4, pp. 557-563, 2018, DOI:10.3727/096504017X15000784459799

    Abstract Hepatocellular carcinoma (HCC) is a disease with poor prognosis rates and ineffective therapeutic options. Previous studies have reported the involvement of mitogen-inducible gene 6 (MIG-6) as a negative regulator in tumor formation. MicroRNAs (miRNAs) play crucial roles in the development of different types of cancer. However, the underlying mechanisms of miRNAs in HCC are poorly understood. This study was aimed to investigate the role of miR-374a in HCC and its role in the regulation of expression of MIG-6. The results showed that MIG-6 overexpression significantly inhibited cell viability of HepG2 cells after 4 days posttransfection. More >

    Oncology Research, Vol.26, No.2, pp. 307-313, 2018, DOI:10.3727/096504017X15088061795756

    Abstract Recently, long noncoding RNAs (lncRNAs) have emerged as new gene regulators and prognostic markers in several cancers, including glioma. Here we focused on lncRNA LUCAT1 on the progression of glioma. qRT-PCR was used to determine the expression of LUCAT1 and miR-375 in glioma tissues and cells. MTT and Transwell invasion assays were performed to determine the function of LUCAT1 in glioma progression. The bioinformatics tool DIANA was used to predict the targets of LUCAT1. Pearson’s correlation analysis was performed to explore the correlation between LUCAT1 and miR-375. In the present study, we showed that LUCAT1… More >

    Calcitriol induces post-thawed bovine sperm capacitation


    BIOCELL, Vol.47, No.5, pp. 1135-1143, 2023, DOI:10.32604/biocell.2023.027628

    Abstract Background: Capacitation is a set of physiological changes sperms undergo to acquire fertilizing capacity. In vivo, this process is directly associated with high calcium levels in sperm cytoplasm. Calcitriol, the vitamin D hypercalcemic metabolite, is related to human sperm motility, capacitation, and acrosome reaction. This work aimed to study the effect of calcitriol on bull sperm quality parameters and capacitation. Methods: One million freeze-thawed spermatozoa were obtained from different bulls and treated with 20 nM of calcitriol for 30 min. Untreated cells (negative control) and treated ones with calcitriol or heparin (100 µg/mL, positive capacitation control) were… More >

    Oncology Research, Vol.28, No.5, pp. 497-507, 2020, DOI:10.3727/096504020X15929939001042

    Abstract Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and accounts for 85% of all lung carcinomas. The hepatocyte growth factor receptor (c-Met) has been considered as a potential therapeutic target for NSCLC. Proteasome inhibition induces cell apoptosis and has been used as a novel therapeutic approach for treating diseases including NSCLC; however, the effects of different proteasome inhibitors on NSCLC have not been fully investigated. The aim of this study is to determine a precise strategy for treating NSCLC by targeting c-Met using different proteasome inhibitors. Three proteasome inhibitors, bortezomib,… More >
