26568273 Two significant SNPs within IBSP, rs1054627 and rs17013181, were associated with BMD and postmenopausal osteoporosis by the two-stage strategy, and rs17013181 was also significantly associated with serum IBSP levels.

25973097 the strong correlation between bone sialoprotein and OPN and papillary thyroid carcinoma suggests a role for BSP and OPN in calcification and tumor progression of papillary thyroid carcinoma
25504218 oxidized low-density lipoprotein-induced expression dependent on Runx2 expression
24530278 Bone sialoprotein could be a key mediator of the hypertrophic chondrocytes-induced angiogenesis of osteoarthritis.
24071501 Current evidence demonstrates that BSP and OPN, play significant roles in bone metastasis of osteotropic malignancies derived from breast, prostate, lung, thyroid, and multiple myeloma. [review]
23726130 High expression of bone sialoprotein in breast neoplasms was associated with cytokeratin-positive cells in bone marrow, but not with lymph node metastasis.
23667544 BSP silencing decreased the integrin alphavbeta3 and beta3 levels, in turn inhibiting cell migration and invasion and decreasing the ability of the cells to metastasize to bone.
23485603 results indicate that FGF2 increases BSP transcription by targeting the FRE and AP1 elements in the proximal promoter of the human BSP gene.
23314561 IBSP mRNA is over expressed in carotid atheroma plaque (3.74 fold, p = 1.41E-09) in an intraindividual comparison.
