This study also showed that POCU1b treatment prevents the expression of ADRP sellekchem and perilipin by both attenuating lipid accumu lation and activating AMPK phosphorylation. Thus, POCU1b is worthwhile to further investigate for its potential pharmacological effect in metabolic disorders, specifically obesity. Background Bone is a mineralized tissue composed of several cell types, which undergoes a continuous renewal and repair process called bone remodeling. Bone remodeling is accomplished by bone forming osteoblasts and bone resorbing osteoclasts Inhibitors,Modulators,Libraries that reside in the bone. The de velopment and differentiation of these 2 cell types are tightly regulated by a number of endogenous substances such as hormones, growth factors, and cytokines.

These factors are secreted through the endocrine, para crineautocrine, and neurocrine systems, and modulate the balance between bone forming and Inhibitors,Modulators,Libraries bone resorbing cells in the marrow microenvironment. Osteoporosis re sults when bone resorption and bone formation are imbalanced and excess bone breakdown exceeds bone building. Bone resorption inhibitors, e. g, bispho sphonates, calcitonin, and estrogen, were designed as therapeutic targets to treat osteoporosis. However, the efficiency of these drugs in improving bone mass is very small, certainly no more than 2% per year. Therefore, teriparatide, an anabolic agent, which stimu lates bone formation and corrects characteristic changes in the trabecular microarchitecture in established osteo Inhibitors,Modulators,Libraries porosis, is a new approach to treat osteoporosis.

Bone remodeling is regulated through a balance of bone forming and bone Inhibitors,Modulators,Libraries resorbing cell activities that to gether maintain bone mass and mineral homeostasis. New bone formation is mainly controlled by osteoblasts. therefore, agents that act to either increase proliferation of cells of the osteoblastic lineage or induce differenti ation of osteoblasts can enhance bone formation. The biological Inhibitors,Modulators,Libraries mechanism of osteoporosis is still un clear. However, it is likely related to decreased availa bility or effects of bone growth factors such as bone morphogenetic proteins. BMPs were first dis covered as a result of their capacity to induce ectopic bone formation in rodents, and the protein structure of BMPs are similar to the transforming growth factor B superfamily. BMPs are secreted proteins, which play crucial roles in bone formation and bone cell differenti ation through stimulation of alkaline phosphatase activity as well as synthesis of proteoglycan, collagen, and osteopontin. A previous study showed linkage of osteoporosis to specific polymorphisms in the BMP 2, ALP and OPN genes, revealing that they are osteoporosis associated genes.
