Was applied so that you can perform statistical evaluation of experimental benefits. All values are offered as mean ?S.E.M. Every single experiment was conducted independently at the very least 3 occasions. Evaluation of normalised data of only two groups was completed using the one-sample t-test. Comparison involving two groups was accomplished employing the unpaired t-test. P-values 0.05 were thought of as statistically substantial.Conflict of Interest The authors declare no conflict of interest.Acknowledgements. We’re grateful to Prof Dr Wolfgang Jelkmann for his ongoing support. Unique thanks to Susann Schindler, Bettina Rudzewski, Tanja Svensson, Ann-Katrin Hellberg-Schnieder and Patricia Rouina for exceptional technical help. MKL was supported by the ‘Promotionsstipendium 17a-Hydroxypregnenolone MedChemExpress Exzellenzmedizin’ granted by the University of Luebeck.Author contributions MM and RD made the experiments. MKL provided scientific input. MM performed the experiments, analysed the data and wrote the manuscript. RD and MKL critically reviewed the manuscript.1. Bertout JA, Patel SA, Simon MC.
