Biomarker: ANXA2

Histology type: endometrial carcinoma

Country: China

Region: Shengjing

Followed up time :

Subgroup 1 name : positive expression

Subgroup 1 number: 80

Subgroup 2 name: High

Subgroup 2 number: 55

Conclusion: Expression levels of ANXA2 and HE4 were closely related to the malignant biological behavior of endometrial carcinoma, and ANXA2 was an independent risk factor for poor prognosis. The expression of ANXA2 and HE4 can affect each other.

Sample type : tissue

Sample method: immunohistochemistry

Expression pattern : co-expression of ANXA2 and HE4

Expression elevation: Consider a positive result if there are buffy granules in the cell membrane and cytoplasm. According to the chromatosis intensity, no pigmentation, light yellow, buffy, and brown are scored 0, 1, 2, and 3, respectively. We choose 5 high-power fields in series from each slice, then score them and take the mean percentage of the chromatosis cells: chromatosis cells that account less than 5 % are 0, 5 % to 25 %: 1, 26 % to 50 %: 2, 51 % to 75 %: 3, and greater than 75 %: 4. Multiply these 2 numbers: 0 to 2 is considered (−); 3 to 4, (+); 5 to 8, (++); and 9 to 12, (+++).

Funtion Uniprot: Calcium-regulated membrane-binding protein whose affinity for calcium is greatly enhanced by anionic phospholipids. It binds two calcium ions with high affinity. May be involved in heat-stress response. Inhibits PCSK9-enhanced LDLR degradation, probably reduces PCSK9 protein levels via a translational mechanism but also competes with LDLR for binding with PCSK9 (PubMed:18799458, PubMed:24808179, PubMed:22848640).
