Molecular analysis reveals reduced TSC2 expression in adult sporadic astrocytomas and ependymomas, suggesting a role in adult brain tumor pathogenesis.

Key Points

To determine whether TSC2 RNA and tuberin protein levels are reduced in sporadic astrocytomas and ependymomas from patients without tuberous sclerosis complex.
Analyzed tumor tissue specimens from 49 adult astrocytomas, 10 pediatric astrocytomas, and 13 ependymomas.
Evaluated TSC2 RNA and tuberin protein expression using reverse transcriptase-polymerase chain reaction (RT-PCR) and immunoblotting.
Reduced or absent TSC2 expression was observed in 18 of 40 (45%) adult high-grade astrocytomas and 4 of 8 (50%) adult low-grade astrocytomas, including 1 giant cell astrocytoma.
Zero of 10 (0%) pediatric low-grade astrocytomas demonstrated reduced TSC2 expression.
Reduced or absent tuberin was detected in 2 of 6 (33%) analyzed ependymomas.
