Translational profiling in childhood acute lymphoblastic leukemia: no evidence for glucocorticoid regulation of mRNA translation.

Background: Glucocorticoids (GCs) are natural stress induced steroid hormones causing cell cycle arrest and cell death in lymphoid tissues. Therefore they are the central component in the treatment of lymphoid malignancies, in particular childhood acute lymphoblastic leukemia (chALL). GCs act mainly via regulating gene transcription, which has been intensively studied by us and others.

Estimates of genetic and environmental contribution to 43 quantitative traits support sharing of a homogeneous environment in an isolated population from South Tyrol, Italy.

As part of the genomic health care program 'GenNova', we measured 43 quantitative traits in 1,136 subjects living in three isolated villages in South Tyrol (Italy), for which extended genealogical information was available. Thirty-seven of the studied traits had been previously investigated in other populations, while six of them are, to the best of our knowledge, studied here for the first time. For all 43 traits we estimated narrow-sense heritability, individual-specific environmental effects, and shared environmental effects.
