Background: In a study of Mexican Americans, we performed analyses of GEI and pleiotropy in the axis in relation to MS. GH/IGF-1 axis components were studied. Model parameters and likelihoods were estimated by maximum likelihood.
Results: Pleiotropy was observed for IGFBP3 (p
Conclusions: IGF-I and IGFBP3 are genetically correlated with MS whereas MS influences the additive genetic variance in IGFBP1 variables mainly but also in IGF-I somewhat by virtue of the VH exhibited by IGF-I/IGFBP1.

Many processes are regulated by the Phosphatidylinositol 3 kinase (PI3K) pathway in the cell including cell survival, metabolism, and apoptosis. Increased activation of the PI3K pathway is a hallmark of many cancers which can be oftentimes attributed to the mutation of PTEN, which encodes an enzyme that performs the reverse reaction of PI3K. When PTEN is null-mutated, this creates a constitutively active PI3K pathway and constitutively active AKT. Since AKT phosphorylates conserved residues on FOXO transcription factors to mark them for nuclear export, this renders FOXO inactive. However, new research has provided evidence that FOXO is still present in …
