This study presents a series of supplementary figures illustrating the interactions between AEG-1 and Akt kinases, specifically focusing on Akt1 and Akt2 signaling pathways. The results, showcased in multiple figures, examine the impact of different siRNAs on AEG-1 expression and subsequent effects on phosphorylation levels of Akt and associated proteins over various time points. Notably, the analysis includes linear regression of phosphorylation half-lives and expression levels under various experimental conditions, providing crucial insights into the role of AEG-1 in tumorigenesis.
