- Benefits for COST and for the COST Action MitoEAGLE
- WG1: I think that we could contribute via participation in the evaluation of the protocols, and helping to develop them further. In addition, we have been working on the establishing a database that would allow us to keep protocol details, cell isolation and several other aspects. There is nothing very advanced, but we could contribute to establishing such data collection practice. In addition, we, as opposed to many others, happen to use Strathkelvin respirometer. This alternative hardware would allow us to verify whether the protocols work on them as well.
- WG2: Our main research subject is the heart muscle cells. So, we could contribute in datasets for several animals (rat, trout, mice [WT and KOs]). In collaboration with WG1, it would be possible to report data in standardized format.
MitoEAGLE Short-Term Scientific Mission
- Work Plan summary
- The aims of this STSM are:
- Work Plan summary
-  establishing new collaboration between the laboratories of Prof. Uwe Schlattner and Dr. Marko Vendelin in the field of research tightly coupled to mitochondrial physiology in the context of aging, gender differences, and environment;
-  establishing user expectations on data collection and management in experiments linked to mitochondrial physiology.
- During STSM, we plan
- * to discuss the latest results obtained in the laboratories;
- * write a prototype mathematical model to calculate movement of molecules of interest between mitochondrial periphery and intermembrane space taking into account novel developments in ATP/AMP ratio sensing developed by Prof Uwe Schlattner;
- * follow the workflow established during experiments and the data analysis in Prof. Uwe Schlattner with the perspective of taking it into account in data processing and collection software.
- The discussions are planned to be done formally, through two seminars (one for a group and one for the whole laboratory), and informally through discussion with the group and the laboratory members. In the seminars, I plan to present our latest results on comparison of respiration kinetics performed on male and female mice and an overview of the database software developed in our laboratory. If ready for presentation, some other results will be presented as well.
- STSM is planned to be started on Monday (early flight from Tallinn) with the seminar on Monday afternoon in Grenoble, and finished on Friday.
