Survivin expression induced by doxorubicin in cholangiocarcinoma

Table 2 Expression level of survivin mRNA

Group	n	Survivin/β-actin	t	P
A	7	0.4210 ± 0.0551	bt = 45.89, dt = 12.54	bP, dP < 0.001
B	7	0.8481 ± 0.0713	bt = 26.11	bP < 0.001
C	7	1.7034 ± 0.0493

Survivin mRNA expression level was determined by survivin/β-actin protein. Data were expressed as mean ± SD, b vs C (48 h after adding doxorubicin), d vs B (24 h after adding doxorubicin), A: Normal Qbc939.
