Omentin protects H9c2 cells against docetaxel cardiotoxicity

Background : Association between obesity and cardiovascular diseases is well known, however increased susceptibility of obese patients to develop several cancer types is not so commonly known. Current data suggest that poorer overall survival in cancer patients might be associated to non-cancer-related causes such as higher risk of cardiotoxicity in obese patients treated with chemotherapeutic agents. Omentin, a novel adipokine decreased in obesity, is actually in the spotlight due to its favourable effects on inflammation, glucose homeostasis and cardiovascular diseases. Also, recent data showed that in vitro anthracycline-induced cardiomyocyte apoptosis is counteracted by omentin suggesting its cardioprotective role. Objective: Our aim was to evaluate omentin effects against docetaxel toxicity. Results: Our data indicate that omentin inhibits docetaxel-induced viability loss and that increased viability is associated to decreased caspase-3 expression and cell death. Although omentin reduces NOX4 expression, it failed to reduce docetaxel-induced reactive oxygen species production. Our results indicate that omentin decreases docetaxel-induced endoplasmic reticulum stress, suggesting that cardioprotective role might be associated to ERS inhibition. Conclusion : These data suggest that omentin treatment may contribute to decrease susceptibility to DTX-induced cardiotoxicity.This work was supported by Fundación Mutua Madrileña 2014 (R.L.), Red de Investigación Cardiovascular (RIC) (RD12/0042/0039) an initiative of ISCIII (J.R.G-J), Programa de Consolidación de Unidades de Investigación Competitivas do SUG (GPC 2013-051) of Xunta de Galicia (J.R.G-J) and Centro de Investigación Biomédica en Red de Enfermedades Cardiovasculares (CIBERCV) (CB16/11/00226) of Instituto de Salud Carlos III (J.R.G-J).

Bioelectronics-on-a-chip for cardio myoblast proliferation enhancement using electric field stimulation

Background: Cardio myoblast generation from conventional approaches is laborious and time-consuming. We present a bioelectronics on-a-chip for stimulating cells cardio myoblast proliferation during culture. Method: The bioelectronics chip fabrication methodology involves two different process. In the first step, an aluminum layer of 200 nm is deposited over a soda-lime glass substrate using physical vapor deposition and selectively removed using a Q-switched Nd:YVO4 laser to create the electric tracks. To perform the experiments, we developed a biochip composed of a cell culture chamber fabricated with polydimethylsiloxane (PDMS) with a glass coverslip or a cell culture dish placed over the electric circuit tracks. By using such a glass cover slip or cell culture dish we avoid any toxic reactions caused by electrodes in the culture or may be degraded by electrochemical reactions with the cell medium, which is crucial to determine the effective cell-device coupling. Results: The chip was used to study the effect of electric field stimulation of Rat ventricular cardiomyoblasts cells (H9c2). Results shows a remarkable increase in the number of H9c2 cells for the stimulated samples, where after 72 h the cell density double the cell density of control samples. Conclusions: Cell proliferation of Rat ventricular cardiomyoblasts cells (H9c2) using the bioelectronics-on-a-chip was enhanced upon the electrical stimulation. The dependence on the geometrical characteristics of the electric circuit on the peak value and homogeneity of the electric field generated are analyzed and proper parameters to ensure a homogeneous electric field at the cell culture chamber are obtained. It can also be observed a high dependence of the electric field on the geometry of the electrostimulator circuit tracks and envisage the potential applications on electrophysiology studies, monitoring and modulate cellular behavior through the application of electric fieldsThis work was partially supported by Mineco through the projects FIS 2015–71933-REDT and RTI 2018–097063-B-I00, Consellería de Educación Program for Development of a Strategic Grouping in Materials – AeMAT Grant No. ED431E2018/08, Xunta de Galicia ref.
