Accumulating evidence has indicated that long non-coding RNAs (lncRNAs) are critically involved in tumor progression. In current study, we reported a novel lncRNA signature correlated with bladder cancer development. Particularly, the lncRNA long stress-induced noncoding transcript 5 (LSINCT5) is significantly upregulated in human bladder cancer cell lines and tumor specimens. Meanwhile, high LSINCT5 expression correlates with poor prognosis, enhances tumor sphere formation and invasion in vitro. In vivo xenograft tumor growth is also elevated by LSINCT5 overexpression...

Epithelial to mesenchymal transition (EMT) serves important roles in tumor invasion, metastasis, formation of cancer initiating cells (CICs) and drug resistance. HLA‑F adjacent transcript 10 (FAT10) has been proposed as an oncogene in bladder cancer. However, the functional contribution of FAT10 to EMT and the formation of CICs remains unclear in bladder cancer. The present study reports that FAT10 protein expression is upregulated in bladder cancer cell lines, and the overexpression of FAT10 promotes EMT and the formation of CICs in bladder cancer UMUC‑3 cells...

We previously showed that microRNA-429 (miR-429) played an important role in epithelial-mesenchymal transition (EMT) of urothelial cell carcinoma of the bladder. We herein evaluated the expression of miR-429 in bladder cancer and its potential relevance to clinicopathological characteristics and patient survival. Relative expression levels of miR-429 in surgical bladder cancer tissue specimens obtained from 76 patients with bladder cancer were measured by chromogenic in situ hybridization. miR-429 expression was significantly higher in specimens from alive patients than expired patients in both of 5-year overall survival (OS) (0...

The therapeutic approaches developed around immune system modulation find the therapeutic contribution of intravesical Bacillus Calmette Guerin (BCG) for transitional cell bladder cancer an unquestionable example as a proof of concept of antitumor immunotherapy since more than 30 years ago. Intravesical immunotherapy for urothelial carcinomas is considered with periodic intravesical instillations schedules, and the one with longer historic development and wider diffusion is BCG in the form of suspension. BCG is a unique strain obtained from Mycobacterium bovis at the end of the first third of the XX century and represents the historically most successful immunotherapeutic modality of all tumors with a high level body of evidence...

Aberrant activation of hepatocyte growth factor/scatter factor (HGF/SF) and its receptor, Met, is involved in the development and progression of many human cancers. In the screening assay of extracts from the root tuber of Tetrastigma hemsleyanum Diels et Gilg, isoquercitrin inhibited HGF/SF-Met signaling as indicated by its inhibitory activity on HGF/SF-induced cell scattering. Further analysis revealed that isoquercitrin specifically inhibited HGF/SF-induced tyrosine phosphorylation of Met. We also found that isoquercitrin decreased HGF-induced migration and invasion by parental or HGF/SF-transfected bladder carcinoma cell line NBT-II cells...

Alpha-Klotho (KLα) and beta-Klotho (KLβ) have recently been reported to correlate with cancer prognosis in some malignancies and we previously reported the association between KLα, KLβ, and urothelial carcinoma of the bladder (UCB), indicating that KLβ acts as a tumor promoter. However, the association between gamma-Klotho (KLγ) and cancer prognosis remains unclear. In the present study, we evaluated the association between KLγ and UCB. To evaluate the effect of KLγ on human bladder cancer cell lines in vitro assays were performed...

Bladder cancer (BC) is a severe health burden: it is the fifth most common malignancy in the world and has high recurrence and progression rates. Standard treatment starts with TURB followed by intravesical chemotherapy with Mitomycin C or immunotherapy with BCG. However, successful management still remains a challenge, because approximately 30% of patients have recurrence or progression within 5 years, and treatment has considerable side effects. Anticipating on the upcoming BCG shortage emphasizes, moreover, the necessity to develop and study novel treatments...

Anti-epidermal growth factor receptor (EGFR) antibody therapy is used in EGFR expressing cancers including lung, colon, head and neck, and bladder cancers, however results have been modest. Near infrared photoimmunotherapy (NIR-PIT) is a highly selective tumor treatment that employs an antibody-photo-absorber conjugate which is activated by NIR light. NIR-PIT is in clinical trials in patients with recurrent head and neck cancers using cetuximab-IR700 as the conjugate. However, its use has otherwise been restricted to mouse models...

The Notch pathway has been implicated in both oncogenic and tumour-suppressive roles in cancer depending on the tissue type and cellular context. However, until recently, little was known about the pathway in bladder cancer. Studies have revealed that NOTCH1 copy number and expression are decreased in bladder cancer and NOTCH1 activation in bladder cancer cell lines reduces proliferation, suggesting that NOTCH1 acts as a tumour suppressor. Furthermore, in transgenic models, bladder cancer is promoted by bladder-specific inactivation of a component of the γ-secretase complex, which liberates the intracellular domain of neurogenic locus Notch homologue protein (NOTCH) and starts the signalling cascade...

Long noncoding RNAs (lncRNAs) have been identified to have more and more important roles in tumorigenesis and may be novel biomarker for cancer therapy. LncRNA TP73-AS1 is a novel identified lncRNA that has been demonstrated to be increased in several cancers, however, its function in bladder cancer remains unknown. The aim of this work was to examine the expression and role of lncRNA TP73-AS1 in bladder cancer. The expression levels of lncRNA TP73-AS1 in bladder cancer tissues and cell lines were determined by quantitative real-time PCR (qRT-PCR), and its clinical significance was assessed by statistical analysis...
