MMP-13 is one of the critical mediators of the effect of HDAC4 deletion on the skeleton

Histone deacetylase 4 (Hdac4) regulates chondrocyte hypertrophy. Hdac4− / − mice are runted in size and do not survive to weaning. This phenotype is primarily due to the acceleration of onset of chondrocyte hypertrophy and, as a consequence, inappropriate endochondral mineralization.

Hydroxyapatite coating on PEEK implants: Biomechanical and histological study in a rabbit model

A bioactive two-layer coating consisting of hydroxyapatite (HA) and yttria-stabilized zirconia (YSZ) was investigated on cylindrical polyetheretherketone (PEEK) implants using ion beam assisted deposition (IBAD). Post-deposition heat treatments via variable frequency microwave annealing with and without subsequent autoclaving were used to crystallize the as-deposited amorphous HA layer.

Overexpression of Gα11 in Osteoblast Lineage Cells Suppresses the Osteoanabolic Response to Intermittent PTH and Exercise

Intermittent parathyroid hormone (iPTH) treatment and mechanical loading are osteoanabolic stimuli that are partially mediated through actions on G protein-coupled receptors (GPCRs). GPCR signaling can be altered by heterotrimeric G protein Gα subunits levels, which can therefore lead to altered responses to such stimuli.

A novel human PTH analog [Cys25]hPTH(1–34) restores bone mass in ovariectomized mice

Recently, an arginine-to-cysteine homozygous mutation at position 25 in mature parathyroid hormone was reported in a Korean patient with hypoparathyroidism. To clarify whether the high bone mass phenotype observed in this patient was related to the hypoparathyroidism itself or to chronic elevation of mutant PTH.

Adenosine A2B receptors play an important role in bone homeostasis

Bone homeostasis is a finely regulated mechanism involving different molecular pathways including adenosine signaling. The aim of this study is to determine the bone phenotype of adenosine A2B receptor knockout (A2BRKO) mice and to measure their ability to form new bone. Moreover, we analyzed the functionality of osteoclasts and osteoblasts from A2BRKO mice.
