Flexoelectricity in Bones

Bones generate electricity under pressure, and this electromechanical behavior is thought to be essential for bone’s self-repair and remodeling properties. The origin of this response is attributed to the piezoelectricity of collagen, which is the main str ...

Glucocorticoid deficiency causes transcriptional and post-transcriptional reprogramming of glutamine metabolism

Benjamin Dieter Weger, Meltem Weger

Background: Deficient glucocorticoid biosynthesis leading to adrenal insufficiency is life-threatening and is associated with significant co-morbidities. The affected pathways underlying the pathophysiology of co-morbidities due to glucocorticoid deficienc ...

The Notch Ligand Jagged1 Regulates the Osteoblastic Lineage by Maintaining the Osteoprogenitor Pool

Freddy Radtke

Notch signaling is critical for osteoblastic differentiation; however, the specific contribution of individual Notch ligands is unknown. Parathyroid hormone (PTH) regulates the Notch ligand Jagged1 in osteoblastic cells. To determine if osteolineage Jagged ...

Importance of trabecular anisotropy in finite element predictions of patellar strain after Total Knee Arthroplasty

Dominique Pioletti, Alexandre Terrier, Adeliya Latypova

Patellar fracture and anterior knee pain remain major complications after Total Knee Arthroplasty (TKA). Patient-specific finite element (FE) models should help improve understanding of these complications through estimation of joint and bone mechanics. Ho ...

Osteogenesis imperfecta: from diagnosis and multidisciplinary treatment to future perspectives

Dominique Pioletti, Lee Ann Laurent-Applegate

Osteogenesis imperfecta is an inherited connective tissue disorder with wide phenotypic and molecular heterogen- eity. A common issue associated with the molecular ab- normality is a disturbance in bone matrix synthesis and homeostasis inducing bone fragil ...

Joint mouse-human phenome-wide association to test gene function and disease risk

Johan Auwerx, Zhi Li, Evan Graehl Williams, Xu Wang, Virginija Jovaisaite

Phenome-wide association is a novel reverse genetic strategy to analyze genome-to-phenome relations in human clinical cohorts. Here we test this approach using a large murine population segregating for similar to 5 million sequence variants, and we compare ...
