Regulation of the bone vascular network is sexually dimorphic (2019)
Journal Article
Goring, A., Sharma, A., Javaheri, B., Smith, R. C., Kanczler, J. M., Boyde, A., Hesse, E., Mahajan, S., Olsen, B. R., Pitsillides, A. A., Schneider, P., Oreffo, R. O., & Clarkin, C. E. (2019). Regulation of the bone vascular network is sexually dimorphic. Journal of Bone and Mineral Research, https://doi.org/10.1002/jbmr.3825

Osteoblast (OB) lineage cells are an important source of vascular endothelial growth factor (VEGF), which is critical for bone growth and repair. During bone development, pubertal differences in males and females exist, but little is known about whet... Read More about Regulation of the bone vascular network is sexually dimorphic.

Sost haploinsufficiency provokes peracute lethal cardiac tamponade without rescuing the osteopenia in a mouse model of excess glucocorticoids (2019)
Journal Article
Javaheri, B., Herbert, E., Hopkinson, M., Al-Jazzar, A., & Pitsillides, A. A. (2019). Sost haploinsufficiency provokes peracute lethal cardiac tamponade without rescuing the osteopenia in a mouse model of excess glucocorticoids. American Journal of Pathology, 189(4), 753-761. https://doi.org/10.1016/j.ajpath.2018.12.007

Glucocorticoid-induced secondary osteoporosis is the most predictable side-effect of this anti-inflammatory. One of the main mechanisms by which glucocorticoids achieve such deleterious outcome in bone is by antagonizing Wnt/β-catenin signalling. Scl...

Regional diversity in the murine cortical vascular network is revealed by synchrotron X-ray tomography and is amplified with age (2018)
Journal Article
Núñez, J. A., Goring, A., Javaheri, B., Razi, H., Gomez-Nicola, D., Pitsillides, A. A., Thurner, P. J., Gomez-Nicola, D., Schneider, P., & Clarkin, C. E. (2018). Regional diversity in the murine cortical vascular network is revealed by synchrotron X-ray tomography and is amplified with age. https://doi.org/10.22203/eCM.v035a20

Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply. Insight into the regulation of the blood...

Transient peak-strain matching partially recovers the age-impaired mechanoadaptive cortical bone response (2018)
Journal Article
Javaheri, B., Carriero, A., Wood, M., De Souza, R., Lee, P. D., Shefelbine, S., & Pitsillides, A. A. (2018). Transient peak-strain matching partially recovers the age-impaired mechanoadaptive cortical bone response. https://doi.org/10.1038/s41598-018-25084-6

Mechanoadaptation maintains bone mass and architecture; its failure underlies age-related decline in bone strength. It is unclear whether this is due to failure of osteocytes to sense strain, osteoblasts to form bone or insufficient mechanical stimul...

Sexually dimorphic tibia shape is linked to natural osteoarthritis in STR/Ort mice (2018)
Journal Article
Javaheri, B., Razi, H., Piles, M., De Souza, R., Chang, Y. M., Maric-Mur, I., Hopkinson, M., Lee, P. D., & Pitsillides, A. A. (2018). Sexually dimorphic tibia shape is linked to natural osteoarthritis in STR/Ort mice. Osteoarthritis and Cartilage, 26(6), 807-817. https://doi.org/10.1016/j.joca.2018.03.008

Human osteoarthritis (OA) is detected only at late stages. Male STR/Ort mice develop knee OA spontaneously with known longitudinal trajectory, offering scope to identify OA predisposing factors. We exploit the lack of overt OA in female STR/Ort and i... Read More about Sexually dimorphic tibia shape is linked to natural osteoarthritis in STR/Ort mice.

Spatial relationship between bone formation and mechanical stimulus within cortical bone: Combining 3D fluorochrome mapping and poroelastic finite element modelling (2018)
Journal Article
Carriero, A., Pereira, A. F., Wilson, A. J., Castagno, S., Javaheri, B., Pitsillides, A. A., Marenzana, M., & Shefelbine, S. J. (2018). Spatial relationship between bone formation and mechanical stimulus within cortical bone: Combining 3D fluorochrome mapping and poroelastic finite element modelling. Bone Reports, 8, 72-80. https://doi.org/10.1016/j.bonr.2018.02.003

Bone is a dynamic tissue and adapts its architecture in response to biological and mechanical factors. Here we investigate how cortical bone formation is spatially controlled by the local mechanical environment in the murine tibia axial loading model...

FGF-2 promotes osteocyte differentiation through increased E11/podoplanin expression (2018)
Journal Article
Ikpegbu, E., Basta, L., Clements, D. N., Fleming, R., Vincent, T. L., Buttle, D. J., Pitsillides, A. A., Staines, K. A., & Farquharson, C. (2018). FGF-2 promotes osteocyte differentiation through increased E11/podoplanin expression. Journal of Cellular Physiology, 233(7), 5334-5347. https://doi.org/10.1002/jcp.26345

E11/podoplanin is critical in the early stages of osteoblast-to-osteocyte transitions (osteocytogenesis), however, the upstream events which regulate E11 expression are unknown. The aim of this study was to examine the effects of FGF-2 on E11-mediate... Read More about FGF-2 promotes osteocyte differentiation through increased E11/podoplanin expression.

Sost deficiency does not alter bone’s lacunar or vascular porosity in mice (2017)
Journal Article
Mosey, H., Núñez, J. A., Goring, A., Clarkin, C. E., Staines, K. A., Lee, P. D., Pitsillides, A. A., & Javaheri, B. (2017). Sost deficiency does not alter bone’s lacunar or vascular porosity in mice. Frontiers in Materials, 4(27), https://doi.org/10.3389/fmats.2017.00027

SCLEROSTIN (Sost) is expressed predominantly in osteocytes acting as a negative regulator of bone formation. In humans, mutations in the SOST gene lead to skeletal overgrowth and increased bone mineral density, suggesting that SCLEROSTIN is a key reg...
