    Shuye Lin*†, Bonan Lin*, Xiaoyue Wang*, Yuanming Pan, Qing Xu*, Jin-Shen He*, Wanghua Gong§, Rui Xing, Yuqi He, Lihua Guo*, Youyong Lu, Ji Ming Wang, Jiaqiang Huang*†

    Oncology Research, Vol.25, No.3, pp. 317-329, 2017, DOI:10.3727/096504016X14734735156265

    Abstract The ATPase H+/K+ Transporting Beta Subunit (ATP4B) encodes the b subunit of the gastric H+, K+ -ATPase, which controls gastric acid secretion and is therefore a target for acid reduction. Downregulation of ATP4B was recently observed in human gastric cancer (GC) without known mechanisms. In the present study, we demonstrated that ATP4B expression was decreased in human GC tissues and cell lines associated with DNA hypermethylation and histone hypoacetylation of histone H3 lysine 9 at its intragenic region close to the transcriptional start site. The expression of ATP4B was restored in GC cell lines by treatment with… More >

    Abstract MicroRNA-27b (miR-27b) was recently found to be significantly downregulated in different human cancers. However, evidence of the function of miR-27b in non-small cell lung cancer (NSCLC) remains limited. In this study, we aimed to investigate novel miR-27b-mediated targets or signaling pathways associated with the tumorigenesis and metastasis of NSCLC. Real-time (RT) PCR was performed to examine miR-27b expression in NSCLC specimens. MTT assay, wound-healing assay, and Transwell assay were used to determine cell proliferation, migration, and invasion. Our data indicated that the miR-27b levels were significantly decreased in NSCLC specimens and cell lines (SK-MES-1, H358,… More >

    Li Chen, Guozhang Ma, Xiaohui Cao, Xiaoxia An, Xiguang Liu

    Oncology Research, Vol.26, No.9, pp. 1429-1437, 2018, DOI:10.3727/096504018X15186047251584

    Abstract Melanoma is characterized by aggressive invasion, early metastasis, and resistance to existing chemotherapeutic agents. Accumulated studies have reported that microRNA (miRNA) is a potentially robust molecular tool for developing future therapeutic technologies. Therefore, examining the expression patterns, biological roles, and associated mechanisms of cancer-related miRNAs in melanoma is essential for developing novel therapeutic targets for patients with this disease. In this study, miRNA-331 (miR-331) was underexpressed in melanoma tissues and cell lines. Functional assays revealed that the enforced expression of miR-331 inhibited cell proliferation and invasion. In addition, astrocyte-elevated gene-1 (AEG-1) was identified as a More >

    Abstract Accumulated studies have strongly implicated aberrantly expressed microRNAs (miRNAs) in carcinogenesis and cancer progression of various cancers, including colorectal cancer (CRC). Hence, a comprehensive study of miRNAs and their association with CRC may be a promising therapeutic method for patients with this malignancy. MicroRNA-744 (miR-744) is abnormally expressed in several types of human cancer. Thus far, little is known about the expression, biological roles, and exact mechanisms of miR-744 in CRC. Thus, the present study measured the expression level of miR-744 and investigated its roles and associated molecular mechanisms in CRC. This study demonstrated that… More >

    Abstract Hepatocellular carcinoma (HCC) as one of the most refractory cancers leads to high mortality worldwide. Long noncoding RNAs have been widely acknowledged as important biomarkers and therapeutic targets in HCC. In this study, we investigated the effects of long noncoding RNA FGFR3-AS1 on tumor growth and metastasis in HCC. First, we found that the expression of FGFR3-AS1 was upregulated about threefold in HCC samples and cell lines. We knocked down FGFR3-AS1 in Huh7 and Hep3B cells and found that FGFR3-AS1 knockdown significantly inhibited cell proliferation but induced apoptosis. Moreover, FGFR3-AS1 knockdown led to more HCC More >

    Abstract Saussurea inversa is one of the Tibetan medicine with developed aerenchyma. In this study, we investigated the function of the ShCTR1 gene related to the formation of aerenchyma. The study of the occurrence and formation of aerenchyma in S. inversa has certain theoretical significance in revealing the special mechanism of alpine plants adapting to the environment. The results of yeast two-hybrid experiments showed that S. inversa ShCTR1 interacted with the ShRBOH1, which is a key producer of reactive oxygen species (ROS), and it was hypothesized that ShCTR1 regulation of aerenchyma formation in S. inversa mainly mediated by ROS. Aerenchyma induction and… More >
