Cancers, Vol. 12, Pages 1023: Knockdown of UTX/KDM6A Enriches Precursor Cell Populations in Urothelial Cell Cultures and Cell Lines
olfgang A. Schulz The histone demethylase UTX (gene: KDM6A) directs cell and tissue differentiation during development. Deleterious mutations in KDM6A occur in many human cancers, most frequently in urothelial carcinoma. The consequences of these mutations are poorly understood; plausibly, they may disturb urothelial differentiation. We therefore investigated the effects of UTX siRNA-mediated knockdown in two in vitro models of urothelial differentiation; namely, primary cultures of urothelial epithelial cells treated with troglitazone and PD153035 and the immortalized urothelial cell line HBLAK treated with high calci...

Downregulation of feline sarcoma-related protein inhibits cell migration, invasion and epithelial-mesenchymal transition via the ERK/AP-1 pathway in bladder urothelial cell carcinoma.
Authors: Hu X, Zhang Z, Liang Z, Xie D, Zhang T, Yu D, Zhong C Abstract Feline sarcoma-related protein (Fer) is a nuclear and cytoplasmic non-receptor protein tyrosine kinase and Fer overexpression is associated with various biological processes. However, the clinicopathological characteristics and molecular mechanisms of Fer expression in bladder urothelial cell carcinoma (UCC) have yet to be elucidated. The present study demonstrated that Fer was significantly upregulated in bladder UCC tissues and cell lines. A clinicopathological analysis suggested that Fer expression was significantly associated with tumor sta...

MicroRNA-497 inhibits the proliferation, migration and invasion of human bladder transitional cell carcinoma cells by targeting E2F3.
Authors: Zhang Y, Zhang Z, Li Z, Gong D, Zhan B, Man X, Kong C Abstract Accumulating evidence indicates that microRNAs (miRNAs) play critical roles in regulating cellular processes, such as cell growth and apoptosis, as well as cancer progression and metastasis. Low expression of miR-497 has been observed in breast, colorectal and cervical cancers. Human bladder transitional cell carcinoma (BTCC) progression typically follows a complex cascade from primary malignancy to distant metastasis, but whether the aberrant expression of miR-497 in BTCC is associated with malignancy, metastasis or prognosis remains unknown. ...

MiR-429 reverses epithelial-mesenchymal transition by restoring E-cadherin expression in bladder cancer.
Authors: Wu CL, Ho JY, Chou SC, Yu DS Abstract Epithelial-mesenchymal transition (EMT) accompanying loss of E-cadherin is important for invasiveness and metastasis of bladder cancer. MicroRNAs (miRs) had been associated with cancer progression and differentiation in several cancers. Our goal is to find out the specific miR which modulates EMT in bladder cancer. Real-time quantitative polymerase chain reaction was used to measure the miRs expression in urothelial cell carcinoma (UCC) cell lines. MiR or siRNA mimics was used to regulate miR and mRNA level respectively. Migration and scratch assays were used to determ...

Abstract 1724: Integrated functional RNAi screening and structural genomics identify inverse co-modulators of TP53 family and NF-{kappa}B transitional activation as potential therapeutic targets in head and neck squamous cell carcinoma
Head and neck squamous cell carcinoma (HNSCC) is the 6th most common cancer worldwide with a 50-60% mortality rate. Deregulation of p53 family members in HNSCC occurs in over 90% of cases, preventing transcription of growth arrest and apoptosis genes. Conversely, members of the NF-κB/REL family are aberrantly activated in about ∼70% of cases, and drive expression of pro-proliferation, inflammation, angiogenesis, and therapeutic resistance genes. The function of different TP53 and NF-κB family members are inversely modulated within two major subsets of HNSCC, suggesting that common molecules and pathways coordinate this...

High expression of KPNA2 defines poor prognosis in patients with upper tract urothelial carcinoma treated with radical nephroureterectomy
Conclusions: KPNA2 is a novel independent prognostic marker for bladder recurrence, DFS and OS of UTUC patients who have undergone RNU. Moreover, these data suggest that KPNA2 may be a promising therapeutic target for UTUC.

Abstract 5239: MiR-148a promotes apoptosis in urothelial cell carcinoma of the bladder cells in part by targeting DNMT1
Conclusions: Our work demonstrates for the first time that miR-148a plays a tumor suppressive role in bladder cancer and suggests it could be used as a novel therapeutic agent either alone or in conjunction with chemotherapeutics.
