Followed up time :

Subgroup 1 name : Positive in EC

Subgroup 1 number: 18

Subgroup 2 name: negative in EC

Subgroup 2 number: 11

Conclusion: By Cox multivariate analysis, osteopontin positivity was an independent prognostic factor for disease-free survival (hazard ratio = 3.18, P= 0.035).

Sample type : plasma

Sample method: ELISA,SYBR Green real-time polymerase chain reaction

Expression pattern : positive >218 ng/mL

Expression elevation: cut-off values that represent the 95th percentile of values in healthy controls

Statictics: Mean (SD)

Subgroup 1 age: 51.3 ± 11.1 years

Subgroup 2 age: 52.3 ± 9.1

Funtion Uniprot: Major non-collagenous bone protein that binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction. Acts as a cytokine involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10 and is essential in the pathway that leads to type I immunity.
