AIM: To isolate, clone and sequence gcys-18 overexpressed in gastric carcinoma.
METHODS: gcys-18 was isolated from differential display gel between GC7901 and GES-1 by mRNA differential display PCR, and was cloned into T vector. As a probe gcys-18 was hybridized to total RNAs of GC7901 and GES-1, and was sequenced. Its sequence was screened against GeneBank. According to the obtained sequence, a pair of primers were designed and used to examine 26 specimens of gastric cancers and corresponding paracancerous tissues by quantitative reverse transcriptase PCR.
RESULTS: gcys-18 was isolated and cloned, and confirmed to be expressed higher in GC7901 than in GES-1 by RNA dot blot; gcys-18 was 416 bp, and partly similar to HEK5, and its accepted number in GeneBank was AF071057; 18 out of 26 specimens of gastric cancers and 2 out of correspon ding paracancerous tissues were examined by RT-PCR.
CONCLUSION: gcys-18 may be an important expressed sequence tag in gastric cancer, and takes part in progression of gastric carcinoma.
