OBJECTIVE Genistein is a soy isoflavone that has antitumor activity both in vitro and in vivo. It has been shown that genistein inhibits many type of cancers including prostate cancer (PCa) by regulating several cell signaling pathways and microRNAs (miRNAs). Recent studies suggest that the long non-coding RNAs (lncRNAs) are also involved in many cellular(More)
Our expression signatures of human cancer including bladder cancer (BC) revealed that the expression of microRNA-1 (miR-1) and microRNA-133a (miR-133a) is significantly reduced in cancer cells. In the human genome, miR-1 and miR-133a are located on the same chromosomal region (miR-1-2 and miR-133a-1 on 18q11.2,(More)
Current genome-wide microRNA (miRNA) expression signature analysis using deep sequencing technologies can drive the discovery of novel cancer pathways regulated by oncogenic and/or tumor suppressive miRNAs. We determined the genome-wide miRNA expression signature in bladder cancer (BC) by deep sequencing technology. A total of ten small RNA libraries were(More)
Our recent studies of microRNA (miRNA) expression signatures demonstrated that the epithelial-mesenchymal transition (EMT)-related microRNA-200 family (miR-200s: miR-200a/b/c, miR-141 and miR-429) were significantly downregulated in renal cell carcinoma (RCC) and putative tumor-suppressive miRNAs in RCC. In this study, our aim was to investigate the(More)
MicroRNAs (miRNAs), a class of small noncoding RNAs, regulate protein-coding gene expression by repressing translation or cleaving RNA transcripts in a sequence-specific manner. A growing body of evidence suggests that miRNAs contribute to bladder cancer development, progression and metastasis. Genome-wide miRNA expression signatures have been used to(More)
Our microRNA (miRNA) expression signatures of hypopharyngeal squamous cell carcinoma, maxillary sinus squamous cell carcinoma and esophageal squamous cell carcinoma revealed that miR-375 was significantly reduced in cancer tissues compared with normal epithelium. In this study, we focused on the functional significance of miR-375 in cancer cells and(More)
Our recent study of microRNA (miRNA) expression signature of prostate cancer (PCa) has revealed that the microRNA-143/145 (miR-143/145) cluster is significantly downregulated in cancer tissues, suggesting that these cluster miRNAs are candidate tumor suppressors. The aim of this study was to investigate the functional significance of the miR-143/145 cluster(More)
We have previously found that restoration of tumor suppressive microRNA-1 (miR-1), induced cell apoptosis in bladder cancer (BC) cell lines. However, the apoptosis mechanism induced by miR-1 was not fully elucidated. Alternative splicing of mRNA precursors provides cancer cells with opportunities to translate many oncogenic protein variants, which promote(More)
Based on our microRNA (miRNA) expression signature analysis of maxillary sinus squamous cell carcinoma (MSSCC), we found that miR-1 and miR-133a were significantly reduced in tumor tissues. Quantitative real-time RT-PCR revealed that the expression levels of miR-1 and miR-133a were significantly downregulated in clinical MSSCC tumor tissues compared with(More)
Our recent studies of microRNA (miRNA) expression signatures have indicated that the miR-143/145 cluster is significantly downregulated in several types of cancer and represents a putative tumor-suppressive miRNA in human cancers. The aim of this study was to investigate the functional significance of the miR-143/145 cluster in cancer cells and to identify(More)
