Astemizole inhibits cell proliferation in human prostate tumorigenic cells expressing ether à-go-go-1 potassium channels.

Astemizole inhibits cell proliferation in human prostate tumorigenic cells expressing ether à-go-go-1 potassium channels. Cell Mol Biol (Noisy-le-grand). 2017 Dec 17;63(12):11-13 Authors: Bernal-Ramos G, Hernández-Gallegos E, Vera E, Chávez-López MG, Zúñiga-García V, Sánchez-Pérez Y, Garrido E, Camacho J Abstract Prostate cancer (PC) is the main cause of cancer mortality in men worldwide. Therefore, novel treatments for PC are needed. Ether à-go-go-1 (Eag1) potassium channels display oncogenic properties, and have been suggested as early tumor markers and therapeutic targets for different cancers. These channels are overexpressed in many human tumors including PC. Astemizole targets several molecules involved in cancer including Eag1 channels, histamine receptors and ABC transporters. Here we studied Eag1 mRNA expression and protein levels in the non-tumorigenic and non-invasive human prostate RWPE-1 cell line, and in the tumorigenic and highly invasive human prostate WPE1-NB26 cell lines. The effect of astemizole on cell proliferation and apoptosis was also studied. The human prostate cell lines RWPE-1 and WPE1-NB26 were cultured following the provider´s instructions. Eag1 mRNA expression and protein levels were studied by real time RT-PCR and immunocytochemistry, respectively. Cell proliferation and apoptosis were studied by a fluorescence AlamarBlue®  assay and flow cy...

Objective: a magnetic resonance imaging (MRI)-conditional needle guidance robot is developed to enhance MRI-guided focal laser ablation (FLA) therapy in patients with focal prostate cancer. Methods: inspired by the workflow of the manual FLA therapy, we developed an MRI-conditional robot with two degrees of freedom to provide the guidance for laser ablation catheter. This robot is powered by pneumatic turbine motors and encoded with the custom-designed optical encoder. The needle could be inserted manually through the designed robotic system, which keeps the patients inside MRI bore throughout the procedure. The robot hard...

Jarwan, Aref Zayed, Ahmed Alhusban, Maha Syouf A chemical and biological approach was used for quality assessment of 16 different eating grape varieties collected in Jordan. A validated LC-ESI-MS/MS method was used for quantitative analysis of resveratrol in grape skin and grape seed extracts. Grape skin extracts showed higher resveratrol content than that of seeds. The antioxidant activity and total phenolic content of seed, skin, and whole berry extracts of the grape varieties were evaluated using the DPPH radica...

Receptor tyrosine kinases (RTKs) are important drivers of cancers. In addition to genomic alterations, aberrant activation of WT RTKs plays an important role in driving cancer progression. However, the mechanisms underlying how RTKs drive prostate cancer remain incompletely characterized. Here we show that non-proteolytic ubiquitination of RTK regulates its kinase activity and contributes to RTK-mediated prostate cancer metastasis. TRAF4, an E3 ubiquitin ligase, is highly expressed in metastatic prostate cancer. We demonstrated here that it is a key player in regulating RTK-mediated prostate cancer metastasis. We further i...

CONCLUSION: Our study showed that after a 3 months delay, the risk of BCR was significantly higher for localized prostate cancer. It seemed possible to extend this period for low-risk patients, whereas it seemed necessary to keep it for intermediate-risks and to reduce it to 2 months for high-risks. LEVEL OF EVIDENCE: 4.

PROSTATE cancer symptoms are triggered by a cancerous growth in this part of the male reproductive system. Early warning signs tend to include problems urinating, as the prostate tumour presses on the tubes for carrying urine. Watch out for these symptoms.
