Expression of survivin in adenoid cystic carcinoma of the lacrimal gland and the effect of intervention with arsenic trioxide in vitro.

Expression of survivin in adenoid cystic carcinoma of the lacrimal gland and the effect of intervention with arsenic trioxide in vitro. Exp Ther Med. 2015 Jul;10(1):330-334 Authors: Pan Y, Xing Y, Wang H Abstract The aim of the present study was to investigate the role of survivin in adenoid cystic carcinoma of the lacrimal gland (LGACC) and the effect of arsenic trioxide (As2O3) intervention in vitro. In total, 13 patients with LGACC were recruited from Renmin Hospital of Wuhan University between 2007 and 2012. The patients were divided into different groups, namely tumor-node-metastasis (TNM)1-2 and TNM3-4, according to the TNM classification. A total of eight samples were included in the TNM1-2 group, while five samples were included in the TNM3-4 group. In addition, six patients that suffered from other diseases (no tumor), but underwent eye surgery, were selected as the controls. The mRNA and protein expression levels of survivin were analyzed. In addition, primary adenoid cystic carcinoma (ACC) cells were cultured and the expression of survivin was silenced using short interfering RNA (siRNA), after which the cell proliferation was determined. Furthermore, the primary cultured ACC cells were treated with different doses of As2O3 to observe the effect on the apoptosis rate. The mRNA and protein expression levels of survivin in the LGACC groups were higher when compared with the controls (P<0.01). In addition, the expression l...
