Context-dependent signal integration by the GLI code: the oncogenic load, pathways, modifiers and implications for cancer therapy.
Bottom Line: Here, the acquisition of GLI(A) levels above a given threshold is predicted to lead to advanced malignant stages.In this review we highlight the concepts of the GLI code, the oncogenic load, the context-dependency of GLI action, and different modes of signaling integration such as that of HH and EGF.Targeting the GLI code directly or indirectly promises therapeutic benefits beyond the direct blockade of individual pathways.

Mentions: Post-translational modifications of GLI proteins result in drastic modifications of activity. For instance, phosphorylation and acetylation of GLI1/2 at specific amino acid residues have a major impact on the ability of GLI proteins to regulate target genes by modifying their binding to target promoters (see Fig. 6) [156–158].
