Description
Summary:The PI3 K/AKT pathway is frequently activated in human cancer. Recently, a G to A point mutation (E17 K) was found in the pleckstrin homology domain of AKT1. We aimed to explore this mutation in cases of urothelial carcinoma. Using chip-based matrix-assisted laser desorption-time-of-flight (MALDI-TOF) mass spectrometer, AKT1 E17 K mutation was searched in 26 total RNA samples obtained from 26 patients known to have urothelial carcinoma. Mutation was found in one out of 26 (3.8%) patients - a 46 year old female with a low grade transitional cell carcinoma located to the lamina propria (Ta disease). Our finding is in line with previous studies showing AKT1 E17 K mutation to be rare. Yet, further studies are required to determine whether this mutation is indeed related to less aggressive disease and carries better prognosis.
