The answer could lie in the central regulation of bone remodelling that is determined by both afferent and efferent signalling through the hypothalamus.
By contrast, wound healing in skin is normal, indicating tissue-specific differences in ECM remodelling that might be clinically exploitable.
As a whole, MMPs play an important role in the extracellular matrix remodelling that occurs under physiological and pathological conditions.
Several reports have indicated that the subchondral bone remodelling that occurs during OA involves both bone resorption and bone formation.
Post-natal myocytes have limited regenerative capacity and their loss leads to cardiac remodelling that involves fibrosis and enlargement of the remaining myocytes.
Functions for the remaining ligands remain to be determined but they are likely to participate in the extensive tissue remodelling that occurs in this highly dynamic tissue as it prepares for blastocyst implantation and pregnancy.
RACK1 becomes translocated to the nucleus in association with the scaffolding protein 14-33zeta in response to cAMP signaling to promote chromatin remodelling that includes H4 histone acetylation resulting in BDNF transcription [ 4, 23].
Initially, upon treatment of MDA-MB-231 breast cancer cells with siRNA directed against TNK2, we observed morphological changes by 48 hours post transfection – indicative of cytoskeletal remodelling – that were characterised by an increasingly elongated stellate appearance with a distinct absence of protrusions at the membrane edges.
Most diseases of bone result from abnormalities in bone remodelling that compromise the architecture, structure and mechanical strength of bone, leading to clinical symptoms such as pain, deformity, fracture and abnormalities of calcium and phosphate homeostasis.
Similarly, in the heart, interstitial fibrosis, along with myocyte hypertrophy and capillary loss, are key components of adverse cardiac remodelling that affect cardiac geometry and function, particularly during diastole [23].
PRAS40 blocks mTORC1 and improves insulin receptor signalling in parallel with blunted hypertrophic and metabolic remodelling that characterizes diabetic cardiomyopathy.
