Abstract: Objective To investigate the expression and significance of adaptor protein containing PH domain,PTB domain,and leucine zipper motif 1 (APPL1) in gastric cancers.Methods Expressions of APPL1 protein and mRNA were detected with immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR) in 47 surgical specimens of gastric carcinomas (GC) and 27 normal gastric tissue specimens,respectively.Results The expression rate of APPL1 protein was 59.6％ (28/47) in GCs,and 26.1％ (6/23) in normal gastric tissues,with a statistically significant difference between two groups (P ＜0.05).The relative expression of mRNA was 0.821 ±0.141 in GCs,and 0.731 ±0.112 in normal gastric tissues,with a statistically significant difference between two groups (P ＜ 0.05).Conclusions The expressions of APPL1 protein and mRNA are increased in GCs,with a close relationship between GC and APPL1.
