背景介紹：Several members of the Ets gene family encode sequence-specific DNA binding proteins that recognize DNA sequences with a centrally located 5'-GGAA-3' element. All of the Ets proteins recognize the same central core sequence but each protein interacts with unique sequences that flank this core. PEA3 binds the motif 5'-AGGAAG-3', while ER81 (also designated ETV1) binds the motif 5'-CGGAA/T-3'. PEA3 is expressed at readily detectable levels in cells of epithelial and fibroblastic origin. Unlike other members of the Ets family, including Ets-1 and Ets-2, PEA3 is not expressed in hematopoietic cells. ER81 is highly expressed in brain, testis, lung and heart. ER81 is also moderay expressed in spleen, pancreas, colon and small intestine. During development, ER81, PEA3 and ERM display unique expression patterns which suggest these transcriptional factors play an important role in organogenesis. ERK-1 activates ER81 transcriptional activity, while MAPKAP kinase 2 inhibits ER81.

1.陽性細胞染色分布有三種類型：細胞漿、細胞核、細胞膜表面。大部分抗原見于細胞漿，可見于整個胞漿或部分胞漿

2.陽性細胞分布可分為灶型和彌漫性

3.由于細胞內含抗原量不同，所以染色強度不一。如果細胞之間染色強度相同，常提示其反應為非特異性

4.陽性細胞染色定位于單個細胞，且與陰性細胞相互交雜分布；而非特異性染色常不限于單個細胞，而是累及一片細胞。

5.切片邊緣、刀痕或褶皺區(qū)域，壞死或擠壓的細胞區(qū)，膠原結締組織等，常表現為相同的陽性染色強度，不能用于判斷陽性。
