title: [Expression of human anti-apoptotic gene survivin and its splice in normal human gastric tissue and gastric cancer].
abstract: OBJECTIVE
  To analyze the expression of human anti-apoptotic gene survivin (SVV) in normal human gastric tissues and gastric cancer.
  
  
  METHODS
  SVV cDNA clone was obtained from human gastric cancer tissues by virtue of RT-PCR, using Dig-marked cRNA probe in situ hybridization to analyze its expression in normal human gastric tissues and gastric cancer.
  
  
  RESULTS
  Two SVV cDNA clones, SVV-S4A and SVV-S1B were obtained. The sequence of the former is identical to that of the well-known SVV cDNA; however, in the sequence of the latter, the third exon was missed, i.e., there are only two exons in SVV-S1B. In situ hybridization showed that SVV-S4A is mainly expressed in gastric cancer tissues whereas SVV-S1B is mostly expressed in normal gastric tissues.
  
  
  CONCLUSIONS
  There is difference between SVV-S4A and SVV-S1B in respect to their characteristics of expression in gastric cancer and normal gastric tissues.
