Study no. 1 and 2 prove my unique translational competence. Starting from a GWAS association signal (identified by us in Nature Genetics 2012, 44:491 and PLoS Genet. 2012, 8:e1002745), I have as senior author in these two translational studies identified a new mechanism for the regulation of cortical bone mass and fracture susceptibility. \\

\\
In this study, we were first to demonstrate that the gut microbiota is a major regulator of bone mass, a finding that opened a completely new research field (518 citations). \\

Body weight homeostat that regulates fat mass independently of leptin in rats and mice. Proc Natl Acad Sci U S A 2018; 115:427-432\\
\\
I identified a homeostatic regulation of body weight (“gravitostat”), depending on body weight sensing in osteocytes within the bone in rodents. In a subsequent human translational randomized clinical trial, we demonstrated that increased weight loading reduces body weight and fat mass in obese subjects (EClinicalMedicine 2020, 22:100338). \\

\\
We identified the WNT modulator RSPO3 to be causally associated with trabecular bone mass and fracture risk in humans using Mendelian Randomization analyses. Subsequent mechanistic studies revealed that RSPO3 increases trabecular bone mass via a cell-autonomous effect in osteoblasts in mice. \\

\\
In this recent article, we demonstrate that the associations for trabecular and cortical bone mineral density with coronary artery calcification, surprisingly, are in opposite directions. This suggests a differential role of trabecular and cortical bone on the risk of coronary artery calcification. We propose that distinct pathophysiological mechanisms exist for the trabecular vs cortical bone in the bone-vascular axis.\\

\\
In these two clinical epidemiology studies (publications no. 9-10), we used our recently established unique population-based Gothenburg cohort with detailed childhood growth data and information on later adult diseases. We demonstrated that pubertal timing, and thereby the onset of adult sex steroid exposure, predicts adult fracture risk, while BMI change specifically during puberty is a major predictor of adult cardiovascular mortality.
