Published Protocol: Simple Analysis of Gel Images With IOCBIO Gel Software

Lucia Jaska, Rikke Birkedal, Martin Laasmaa, Marko Vendelin Bio-protocol, 2024 Aug 20; 14(16):e5053 PMID: 39210956 DOI: 10.21769/BioProtoc.5053 Abstract Gel image analyses are often difficult to reproduce, as the most commonly used software, the ImageJ Gels plugin, does not automatically record any steps in the analysis process. This protocol provides detailed steps for image analysis using IOCBIO Gel software with western blot as an example; however, the protocol is applic...

Simple analysis of gel images with IOCBIO Gel

Jaak Kütt, Georg Margus, Lauri Kask, Triinu Rätsepso, Kärol Soodla, Romain Bernasconi, Rikke Birkedal, Priit Järv, Martin Laasmaa, Marko Vendelin BMC Biology 2023 Oct 20;21(1):225 PMID: PMC10589977 DOI: 10.1186/s12915-023-01734-8 Abstract Background: Current solutions for the analysis of Western Blot images lack either transparency and reproducibility or can be tedious to use if one has to ensure the reproducibility of the analysis. Results: Here, we present an open-sou...

Cardiomyocytes from female compared to male mice have larger ryanodine receptor clusters and higher calcium spark frequency

Martin Laasmaa, Jelena Branovets, Jekaterina Stolova, Xin Shen, Triinu Rätsepso, Mihkel Jaan Balodis, Cärolin Grahv, Eliise Hendrikson, William Edward Louch, Rikke Birkedal, Marko Vendelin The Journal of Physiology, 601(18), 4033–4052 PMID: 37561554 DOI: 10.1113/JP284515 Abstract Sex differences in cardiac physiology are receiving increased attention as it has become clear that men and women have different aetiologies of cardiac disease and require different treatments. The...

Looking for PhD student: mathematical modeling

We have opened competition for a PhD student position: Mathematical modeling of energy transfer and mechanics in theheart In heart muscle cells, energy used by most of the processes in the muscle cells is supplied in the form ofATP by mitochondria. Within this project, you would be designing state-of-the-art mathematical models to unravel mechanisms regulating ATP production in mitochondria, selection of energy transfer pathways between mitochondria and ATP consumers, as well as working o...

Ontogeny of cardiomyocytes: ultrastructure optimization to meet the demand for tight communication in excitation-contraction coupling and energy transfer

Rikke Birkedal, Martin Laasmaa, Jelena Branovets, Marko Vendelin Philos Trans R Soc Lond B Biol Sci. 2022 Nov 21;377(1864):20210321. PMID: 36189816 DOI: 10.1098/rstb.2021.0321 Abstract The ontogeny of the heart describes its development from the fetal to the adult stage. In newborn mammals, blood pressure and thus cardiac performance are relatively low. The cardiomyocytes are thin, and with a central core of mitochondria surrounded by a ring of myofilaments, while the sarco...

Student team project: Software for protein determination

We are looking for a student team working on proteomics gel analysis software. The software is expected to take as an input gel description and photo images containing gel measurements. As an output, software should calculate image intensities in regions that the user can interactively select. The algorithms for that will be provided but need to be implemented by the student team. Example gel image with the marked regions of interest for analysis Software will be released as a cross-platf...

Looking for PhD student

We have opened competition for a PhD student position: Tracking molecular movement to unravel diffusion barriers in cardiac cells This is an interdisciplinary project combining physics and biology to study the intracellular environment in the heart muscle. Through the development of cutting-edge experimental and data analysis approaches, it is expected to reveal intracellular environment properties that govern molecular movements and shape its physiology. So that the heart could produc...

Summer job for students

We are looking for a B.Sc. or M.Sc. student to work full or part-time during the summer and, if there is an interest, for longer. The job is to do Western blots to assess whether the phosphorylation status of some proteins is different in hearts from creatine-deficient mice. Image analysis and insertion into the database is also part of the job. The results can stand alone and form the basis for a thesis. It is an advantage to have experience with laboratory work, but we will be happy to ...
