Reciprocal gene expression of osteoclastogenesis inhibitory factor and osteoclast differentiation factor regulates osteoclast formation.

Nagai, Masazumi, Sato, Nobuko·1999·Biochemical and Biophysical Research Communications

Abstract

Osteoblasts/stromal cells support the formation of osteoclast-like cells (OCL) from osteoclast progenitor cells via expressing a membrane-associated protein, osteoclast differentiation factor (ODF), in the presence of osteotropic factors, whereas the cells secrete a substantial amount of osteoclastogenesis inhibitory factor (OCIF) in the unstimulated state. There are both OCL formation-supporting and the nonsupporting cell lines in osteoblasts/stromal cell lineages. The mechanism that divides osteoblasts/stromal cell lines into the two types is not known. The present study reports that OCL formation-supporting cell line ST2 showed a greatly increased level of ODF mRNA, whereas their OCIF mRNA was drastically diminished in the presence of 1alpha, 25(OH)2-dihydroxyvitamin D3 or prostaglandin E2. In contrast, MC3T3-E1 cells lacking OCL formation-supporting ability did not show a decrease in OCIF mRNA in response to the factors, despite a similar increase in ODF mRNA as ST2 cells. However, inactivated MC3T3-E1 cells secreting nothing supported OCL formation in coculture with human promyelocytic cells, HL60. On the contrary, ST2 cells did not support OCL formation from HL60 cells when cocultured in medium conditioned by 1alpha, 25(OH)2 vitamin D3-treated MC3T3-E1. These findings indicate that reciprocal gene expression of ODF and OCIF in osteoblasts/stromal cells is essential for supporting OCL formation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
