Dataset Summary
| Title | Proteome Profiling of human astrocytes upon both positive and negative actuations of G-quadruplex control systems |
| Description | We report here on an unprecedented comparison of the cellular consequences of G4 chemical stabilization by pyridostatin (PDS) and destabilization by phenylpyrrolocytosine (PhpC) at both transcriptome- and proteome-wide scales in patient-derived human brain cells. Our results show that the stabilization of G4s by PDS triggers the dysregulation of many cellular circuitries, the most drastic effects originating in the downregulation of 158 proteins primarily involved in RNA transactions. In contrast, the destabilization of G4s by PhpC modulates the G4 landscapes in a far more focused manner with the upregulation of 295 proteins mostly involved in RNA transactions as well, thus mirroring the effects of PDS. Our study is the first of its kind to report on the extent of G4-associated cellular circuitries in human cells by systematically pitting the effect of G4 stabilization against destabilization in a direct and unbiased manner. |
