| T1 |
0-131 |
Sentence |
denotes |
Osteopontin is an adhesive factor for myeloma cells and is found in increased levels in plasma from patients with multiple myeloma. |
| T2 |
132-158 |
Sentence |
denotes |
BACKGROUND AND OBJECTIVES: |
| T3 |
159-307 |
Sentence |
denotes |
Osteopontin (OPN) is a non-collagenous matrix protein produced by various cells including osteoblasts, osteoclasts and several types of tumor cells. |
| T4 |
308-466 |
Sentence |
denotes |
It is involved in a number of physiologic and pathologic events including adhesion, angiogenesis, apoptosis, inflammation, wound healing and tumor metastasis. |
| T5 |
467-538 |
Sentence |
denotes |
We wanted to investigate the potential role of OPN in multiple myeloma. |
| T6 |
539-558 |
Sentence |
denotes |
DESIGN AND METHODS: |
| T7 |
559-658 |
Sentence |
denotes |
Myeloma cells and stromal cells from myeloma patients were investigated as potential OPN-producers. |
| T8 |
659-754 |
Sentence |
denotes |
Furthermore, OPN was tested in proliferation, migration and adhesion assays with myeloma cells. |
| T9 |
755-855 |
Sentence |
denotes |
Serum and plasma OPN in myeloma patients were measured by enzyme-linked immunosorbent assay (ELISA). |
| T10 |
856-940 |
Sentence |
denotes |
OPN levels were correlated to disease variables at diagnosis and to disease outcome. |
| T11 |
941-949 |
Sentence |
denotes |
RESULTS: |
| T12 |
950-1087 |
Sentence |
denotes |
Myeloma cells produce OPN, and stromal cells from myeloma patients express higher levels of OPN than stromal cells from healthy controls. |
| T13 |
1088-1143 |
Sentence |
denotes |
The myeloma cell lines ANBL-6 and INA-6 adhered to OPN. |
| T14 |
1144-1282 |
Sentence |
denotes |
NOD/SCID mice inoculated with OPN-producing ANBL-6 cells had elevated levels of murine OPN in serum, whereas human OPN was not detectable. |
| T15 |
1283-1388 |
Sentence |
denotes |
Plasma and serum levels of OPN were significantly higher in myeloma patients than in healthy individuals. |
| T16 |
1389-1420 |
Sentence |
denotes |
Interpretation and Conclusions. |
| T17 |
1421-1598 |
Sentence |
denotes |
Myeloma cell lines adhere to OPN, indicating that elevated stromal expression of OPN may be one of the factors responsible for the retention of myeloma cells in the bone marrow. |
| T18 |
1599-1763 |
Sentence |
denotes |
The elevated plasma OPN levels in myeloma patients could be due to both production of OPN by the tumor cells and tumor-induced production of OPN by non-tumor cells. |
