Roles of Kinases in Osteoblast Function
نویسنده
چکیده
Osteoblasts, as well as osteocytes that are a terminally differentiated form of osteoblasts, are responsible for bone formation by producing bone matrix proteins, which subsequently induce tissue mineralization. Osteoblasts differentiate and mature from their progenitors in response to various regulatory factors including bone morphogenetic proteins (BMPs), Insulin-like growth factor 1 (IGF-1), fibroblast growth factor 2 (FGF-2), parathyroid hormone (PTH), tumor necrosis factor-α (TNF-α), Wnts, and extracellular matrix (ECM) signals. Matrix mineral deposition occurs at the terminal stage of osteoblast differentiation and is associated with maximal expression of osteocalcin (Ocn).

Role of Protein Phosphatase 2A in Osteoblast Differentiation and Function
The reversible phosphorylation of proteins plays hugely important roles in a variety of cellular processes, such as differentiation, proliferation, and apoptosis. These processes are strictly controlled by protein kinases (phosphorylation) and phosphatases (de-phosphorylation). Here we provide a brief history of the study of protein phosphorylation, including a summary of different types of pro...
متن کاملCellular SRC kinases and dsRNA dependent protein kinase (PKR) play key role in intracellular viral (CVB3) replication
SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...

متن کاملP20: The Role of Protein Kinases in Memory
When an experience is encrypted into a long-lasting memory, it is believed that specific sets of neurons in the brain of the animal undergo changes including the strengthening of preexisting synapses and the growth and maintenance of new synaptic connections. These activity-dependent synaptic changes appear to require the coordination of a variety of cellular processes in spatially separated ce...
متن کاملTWEAK/Fn14 interaction regulates RANTES production, BMP-2-induced differentiation, and RANKL expression in mouse osteoblastic MC3T3-E1 cells
Tumour necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK), a member of the TNF family, is a multifunctional cytokine that regulates cell growth, migration, and survival principally through a TWEAK receptor, fibroblast growth factor-inducible 14 (Fn14). However, its physiological roles in bone are largely unknown. We herein report various effects of TWEAK on mouse osteoblastic MC3T3-E1...
