Single-cell RNA sequencing identifies Fgf23-expressing osteocytes in response to 1,25-dihydroxyvitamin D3 treatment

Frontiers in Physiology, 2023
Fibroblast growth factor 23 (FGF23), a hormone, mainly produced by osteocytes, regulates phosphate and vitamin D metabolism. By contrast, 1,25-dihydroxyvitamin D3, the active form of vitamin D, has been shown to enhance FGF23 production.

Differential Expression of Dickkopf 1 and Periostin in Mouse Strains with High and Low Bone Mass

Biology, 2022
By expressing different genes and proteins that regulate osteoclast as well as osteoblast formation, osteocytes orchestrate bone metabolism. The aim of this project was the evaluation of the differences in the osteocytes’ secretory activity in the low ...

Effect of High Static Magnetic Fields on Biological Activities and Iron Metabolism in MLO-Y4 Osteocyte-like Cells

Cells, 2021
There are numerous studies that investigate the effects of static magnetic fields (SMFs) on osteoblasts and osteoclasts. However, although osteocytes are the most abundant cell type in bone tissue, there are few studies on the biological effects of ...

Extracellular Fe2+ and Fe3+ modulate osteocytic viability, expression of SOST, RANKL and FGF23, and fluid flow-induced YAP1 nuclear translocation

Scientific Reports, 2023
Iron overload negatively affects bone mass and strength. However, the impact of iron excess on osteocytes—important bone cells for mechanotransduction and remodeling—is poorly understood.

Overexpression of Lrp5 enhanced the anti-breast cancer effects of osteocytes in bone

Bone Research, 2021
Osteocytes are the most abundant cells in bone, which is a frequent site of breast cancer metastasis. Here, we focused on Wnt signaling and evaluated tumor-osteocyte interactions.

Osteocytes Serve as a Reservoir for Intracellular Persisting Staphylococcus aureus Due to the Lack of Defense Mechanisms

Frontiers in Microbiology, 2022
Chronic staphylococcal osteomyelitis can persist for long time periods causing bone destruction. The ability of Staphylococcus aureus to develop chronic infections is linked to its capacity to invade and replicate within osteoblasts and osteocytes and to

Single cell cortical bone transcriptomics define novel osteolineage gene sets altered in chronic kidney disease

Frontiers in Endocrinology, 2023
IntroductionDue to a lack of spatial-temporal resolution at the single cell level, the etiologies of the bone dysfunction caused by diseases such as normal aging, osteoporosis, and the metabolic bone disease associated with chronic kidney disease (CKD ...

The Mechanosensory Role of Osteocytes and Implications for Bone Health and Disease States

Frontiers in Cell and Developmental Biology, 2022
Bone homeostasis is a dynamic equilibrium between bone-forming osteoblasts and bone-resorbing osteoclasts. This process is primarily controlled by the most abundant and mechanosensitive bone cells, osteocytes, that reside individually, within chambers of

Osteocyte: a Cellular Basis for Mechanotransduction in Bone

Journal of Biomechanical Science and Engineering, 2007
Osteocyte is the most abundant cell type in bone, and the only cell type located inside the mineralized matrix. The striking structural design of bone predicts an important role for osteocytes in determining bone structure and function.

CSF‐1 in Osteocytes Inhibits Nox4‐mediated Oxidative Stress and Promotes Normal Bone Homeostasis

JBMR Plus, 2020
CSF‐1 is a key factor in regulating bone remodeling; osteocytes express CSF‐1 and its receptor. Viable osteocytes are essential for bone remodeling through cell–cell contact and secretion of factors that regulate osteoblasts and osteoclasts.
