Abstract

Metabolic bone diseases, such as rheumatoid arthritis (RA) and osteoporosis, are characterized as imbalance between bone formation and bone resorption, leading to bone microarchitecture damage and bone mineral density loss. Bone loss is huge threat for older people's health, which imposes a heavy financial burden on patients and their families. However, the effectiveness of bone loss treatment in clinical practice is limited. With the understanding of the molecular and cellular regulators and mediators of bone remodelling, we know that some signaling pathways and inflammatory cytokines play important roles in the development of RA and osteoporosis. The increasing evidence showed that tumor necrosis factor (TNF)-like weak inducer of apoptosis (Tweak)/fibroblast growth factor-inducible 14 (Fn14) signalling controls a variety of cellular activities in biological processes, such as proliferation, differentiation, and apoptosis and has diverse biological functions in pathological mechanisms like inflammation that are associated with the process of bone metabolism. Recent studies suggest that the interactions between Tweak/Fn14 play critical roles in osteoblast and osteoclast differentiation and apoptosis, especially in those rheumat...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Calcium & Bioenergetics

Bioenergetic processes, including cellular respiration and photosynthesis, concern the transformation of energy by cells. Here is the latest research on the role of calcium in bioenergetics.
