This study aimed to determine if the (pro)renin receptor (ATP6AP2) changes the cellular profile of choriocarcinomas from cytotrophoblast cells to terminally syncytialised cells and ascertain whether this impacts on the invasive potential of choriocarcinoma cells. Additionally, we aimed to confirm that FURIN and/or site 1 protease (MBTPS1) cleave soluble ATP6AP2 (sATP6AP2) in BeWo choriocarcinoma cells and determine whether sATP6AP2 levels reflect the cellular profile of choriocarcinomas. BeWo choriocarcinoma cells were treated with ATP6AP2 siRNA, FURIN siRNA, DEC-RVKR-CMK (to inhibit FURIN activity) or PF 429242 (to inhibit MBTPS1 activity). Cells were also treated with forskolin, to induce syncytialisation, or vehicle and incubated for 48h before collection of cells and supernatants. Syncytialisation was assessed by measuring hCG secretion (by ELISA) and E-cadherin protein levels (by immunoblot and immunocytochemistry). Cellular invasion was measured using the xCELLigence real-time cell analysis system and secreted sATP6AP2 levels measured by ELISA. Forskolin successfully induced syncytialisation and significantly increased both BeWo choriocarcinoma cell invasion (P<0.0001) and sATP6AP2 levels (P=0.02). Treatment with ATP6AP2 siRNA significantly inhibited syncytialisation (decreased hCG secretion (P=0.005), the percent of nuclei in syncytia (P=0.05)), forskolin-induced invasion (P=0.046) and sATP6AP2 levels (P<0.0001). FURIN siRNA and DEC-RVKR-CMK significantly decreased sATP6AP2 levels (both P<0.0001). In conclusion, ATP6AP2 is important for syncytialisation of choriocarcinoma cells and thereby limits choriocarcinoma cell invasion. We postulate that sATP6AP2 could be used as a biomarker measuring the invasive potential of choriocarcinomas. Additionally, we confirmed that FURIN, not MBTPS1, cleaves sATP6AP2 in BeWo cells, but other proteases (inhibited by DEC-RVKR-CMK) may also be involved.

In order to realizing real-time on-line oil monitoring for high-power gearbox’s wear state during operation, a monitoring system is developed on the basis of the ferrograph sensors in this paper. By means of a multi-level monitoring system, a real-time remote monitoring and analysis system of unattended machine wear condition is achieved which can real-time display the image of the wear particles and the wear information of the gears, thus getting such advantages as timely notice and warning, reducing equipment’s damage and maintenance costs . The initial application of system on the real machine shows good results and effects.

Objective: We summarized the progress of the xCELLigence real-time cell analysis (RTCA) technology application in recent years for the sake of enriching and developing the application of RTCA in the field of Chinese medicine. Background: The RTCA system is an established electronic cellular biosensor. This system uses micro-electronic biosensor technology that is confirmed for real-time, label-free, dynamic and non-offensive monitoring of cell viability, migration, growth, spreading, and proliferation. Methods: We summarized the relevant experiments and literature of RTCA technology from the principles, characteristics, applications, especially from the latest application progress. Results and conclusion: RTCA is attracting more and more attention. Now it plays an important role in drug screening, toxicology, Chinese herbal medicine and so on. It has wide application prospects in the area of modern pharmaceutical evaluation and analysis.

ABSTRACT Objectives: To investigate the potential cytotoxicity of the bracket identification dyes commonly used in orthodontic fixed appliances. Materials and Methods: Six bracket brands representing the market in various aspects were selected. Ten sets of each bracket brand were acquired, and the identification dyes on them were scraped. They were tested for cytotoxicity at three different levels of concentration (2.5 mg/mL, 5 mg/mL, and 10 mg/mL), with the aid of a real-time cell analysis system. The results were compared within and between the groups. One-way analysis of variance and Tukey's post hoc test were used for statistical analysis. Results: None of the six investigated dyes displayed cytotoxicity at the 2.5 mg/mL concentration. Of the investigated brands, three at 5 mg/mL and four at 10 mg/mL displayed cytotoxicity. Conclusions: Some of the identification dyes in this study did display cytotoxicity at the higher concentrations tested. Alternative methods for bracket identification should be considered.
