Genetic alterations | RET/PTC1 Re-arrangement | H-Ras (G13R+/-) | N-Ras (Q61R+/-), Akt11 copy gain | PTEN (allele deletion and R130+) | PIK3CA (H1047R+/+) | PIK3CA (E542K+/+) | Akt1 copy gain | - | - | - | - | - |
IC50 of Perifosine (μM) | 3.58 | 4.47 | 4.02 | 1.71 | 2.17 | 10.17 | 4.92 | 35.49 | >1,000 | >1,000 | >1,000 | >1,000 |
IC50 of Temsirolimus (nM) | 0.11 | 0.64 | 3.98 | 0.01 | 7.33 | 0.01 | 110.46 | >1,000 | 44.55 | 18.9 | 0.20 | 458.74 |
Footnotes: Ras, PIK3CA and PTEN were analyzed for mutations, and PIK3CA, PIK3CB, PDK1, Akt-1 and -2 were analyzed for copy number as described in Material and Methods. +/-, heterozygous mutation; +/+, homozygous mutation. The IC50 values were calculated using the Reed-Muench method (21).
