The ins and outs of osteopontin [PDF]

open access: yesOncoImmunology, 2015
The continuous remodeling of progressing tumors demands non-physiologic production of extracellular matrix (ECM) proteins. Among them, osteopontin (OPN) has been largely involved in tumor progression and metastasis. We have recently discovered a new mechanism for OPN in the metastatic spread of mammary carcinoma providing local immunosuppression at the

Osteopontin-c isoform levels are associated with SR and hnRNP differential expression in ovarian cancer cell lines

open access: yesTumor Biology, 2017
Osteopontin-c splicing isoform activates ovarian cancer progression features. Imbalanced expression of splicing factors from serine/arginine -rich and heterogeneous ribonucleoproteins families has been correlated with the generation of oncogenic splicing

TRACP as an Osteopontin Phosphatase [PDF]

open access: yesJournal of Bone and Mineral Research, 2003
Abstract TRACP is synthesized as a latent proenzyme requiring proteolytic processing to attain maximal phosphatase activity. Excision of an exposed loop domain abolishes the interaction between the loop residue Asp146 and a ligand to the redox-sensitive iron of the active site, most likely Asn91, providing a mechanism for the enzyme ...

The role of extracellular matrix phosphorylation on energy dissipation in bone

open access: yeseLife, 2020
Protein phosphorylation, critical for cellular regulatory mechanisms, is implicated in various diseases. However, it remains unknown whether heterogeneity in phosphorylation of key structural proteins alters tissue integrity and organ function.

Normal inflammation and regeneration of muscle following injury require osteopontin from both muscle and non-muscle cells

open access: yesSkeletal Muscle, 2019
Background Osteopontin is secreted by skeletal muscle myoblasts and macrophages, and its expression is upregulated in muscle following injury. Osteopontin is present in many different structural forms, which vary in their expression patterns and effects ...

Osteopontin [PDF]

open access: yesCirculation Research, 1999
Vascular calcification is widely regarded as merely a rare, end-stage, passive, degenerative, and inevitable process of aging. Decades ago, atherosclerosis had been similarly dismissed, but extensive research finally demonstrated its active regulation. Current research is now revising outdated views of vascular calcification.

An antibody-free sample pretreatment method for osteopontin combined with MALDI-TOF MS/MS analysis.

open access: yesPLoS ONE, 2019
Osteopontin is an osteoblast-secreted protein with an aspartic acid-rich, highly phosphorylated, and glycosylated structure. Osteopontin can easily bind to integrins, tumor cells, extracellular matrix and calcium, and is related to bone diseases, various

Osteopontin in Cancer: Mechanisms and Therapeutic Targets

open access: yesInternational Journal of Translational Medicine, 2022
Despite significant advances in the understanding of cancer biology, cancer is still a leading cause of death worldwide. Expression of the tumor microenvironment component, osteopontin, in tumor tissues, plasma, and serum, has been shown to be associated

Neuroprotection by Osteopontin in Stroke [PDF]

open access: yesJournal of Cerebral Blood Flow & Metabolism, 2005
Osteopontin (OPN) is a secreted extracellular phosphoprotein involved in diverse biologic functions, including inflammation, cell migration, and antiapoptotic processes. Here we investigate the neuroprotective potential of OPN to reduce cell death using both in vitro and in vivo models of ischemia.
