Absence of AKT1 in-frame duplications from a series a tumor and cancer cell line genomic DNA samples.
A) Exon-3 amplicons in 10 adult-type GCTs. Control + stands for exon 3 in T14 (carrying the insertion, note the bands at 154 bp and 190 bp), − denotes PCR control (without DNA). Electrophoresis migration was performed in 2% agarose gels of 24 cm to ensure allelic discrimination by size. B) Exon-3 amplicons in colorectal cancer (CRC) samples. C) Exon-3 amplicons in the 60 cell line panel of the National Cancer Institute. Control + stands for the amplicon in T13 (carrying the insertion, note the bands at 144 bp and 192 bp), − denotes PCR control (without DNA). Only one band having the wild-type length was obtained in all the samples tested thus far.
