Abstract:
OBJECTIVETo study the expression and associations of three survivin splicing variants in gastric cancer and normal gastric mucosa, and to evaluate the prognostic significance.
METHODSReal time quantitative RT-PCR was used to detect the expression of three survivin splicing variants in tumor and matched normal gastric mucosa specimens from 77 cases with gastric cancer.
RESULTSThe expression of three survivin splicing variants than upregulated significantly in gastric cancer than those in normal mucosas (P< 0.01). In cancer tissues, the expression rates of survivin, survivin-2B, survivin-deltaEx3 were 100%, 79.8% (61/77), 64.9% (50/77) respectively. The survival rate was significantly lower in the patients with high survivin expression than those with low survivin expression (P< 0.01).
CONCLUSIONAmong three survivin splicing variants, the expression level of wild-type survivin mRNA is an important predictor for prognosis.
