Olfactory receptor as therapeutic target in bladder cancer

(Ruhr-University Bochum) Researchers from Bochum have detected an olfactory receptor in the human bladder that might prove useful for bladder cancer therapy and diagnosis. Using cell culture studies, the team headed by Professor Dr. Hanns Hatt and Dr. Lea Weber demonstrated that the receptor occurs more frequently in bladder cancer tissue than in healthy bladder tissue. Accordingly, significant higher amounts of the receptor could be found in the urine samples of patients.

alho Carla Cruz M. Graça P. M. S. Neves The stabilization of G-Quadruplex DNA structures by ligands is a promising strategy for telomerase inhibition in cancer therapy since this enzyme is responsible for the unlimited proliferation of cancer cells. To assess the potential of a compound as a telomerase inhibitor, selectivity for quadruplex over duplex DNA is a fundamental attribute, as the drug must be able to recognize quadruplex DNA in the presence of a large amount of duplex DNA, in the cellular nucleus. By using different spectroscopic techniques, such as ultraviolet-visible, fluorescence and circular di...

This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships...

Abstract Urinary bladder cancer (UBC) is characterized by frequent recurrence and metastasis despite the standard chemotherapy with gemcitabine and cisplatin combination. Histone modifiers are often dysregulated in cancer development, thus they can serve as an excellent drug targets for cancer therapy. Here, we investigated whether G9a, one of the histone H3 methyltransferases, was associated with UBC development. We first analyzed clinical data from public databases and found that G9a was significantly overexpressed in UBC patients. The TCGA Provisional dataset showed that the average expression level of G9a in p...

In this study, we aimed to investigate the expression, biological function, and regulatory mechanism of miR-532-5p in bladder cancer. Herein, we found that miR-532-5p expression was frequently downregulated in bladder cancer tissues and cell lines compared with normal controls. Functional experiments showed that overexpression of miR-532-5p inhibited the proliferation and invasion of bladder cancer cells, whereas inhibition of miR-532-5p showed opposite effects. Interestingly, bioinformatics analysis predicted high-mobility group protein B3 (HMGB3) as a potential target gene of miR-532-5p. Further experiments showed that m...

Not all that long ago, chemotherapy was the only option to treat most advanced (metastatic) cancers. Because these drugs work by destroying rapidly dividing cells, they harm some healthy cells — such as hair follicles — as well as cancer cells. In the past two decades, cancer treatment has been transformed by targeted drugs and the emergence of chemotherapy. Targeted drugs are designed to home in on specific genes or proteins that are altered or overexpressed on cancer cells. Immunotherapy has been very successful for certain types of advanced cancers, such as lung, bladder, and skin cancers. One form of immuno...

Conclusions: NK cells are frequent among intratumoral lymphocytes in BC. Bladder intratumoral CD56bright NK cells are functional and prognostically relevant whereas CD56dim NK cells are dysfunctional and prevalent in higher stage tumors. Thus, CD56bright NK cells are promising targets in BC. PMID: 30559932 [PubMed]

High-glucose promotes proliferation of human bladder cancer T24 cells by activating Wnt/β-catenin signaling pathway. Eur Rev Med Pharmacol Sci. 2018 Dec;22(23):8151-8160 Authors: Gao L, Xu FM, Shi WJ, Zhang S, Lu YL, Zhao DK, Long YF, Teng RB, Ge B Abstract OBJECTIVE: Bladder cancer is the most prevalent genitourinary malignant disorder worldwide. We aimed to observe effects of high-glucose on bladder cancer proliferation and explore the associated mechanisms. MATERIALS AND METHODS: Human bladder cancer cell line, T24, was divided into Blank, Control (Ctrl), 10 mmol/l, 20 mmol/l and 30 mmol/l ...
