This data repository provides raw datasets for accompanying the paper, "Encoding growth factor identity in the temporal dynamics of FoxO3 under combinatorial regulation by ERK and Akt" by Sampattavanich et al., Cell Systems (2018)
Forkhead box O3 transcription factor (FoxO3) functions as an integrative node for diverse upstream signaling networks, and has been implicated in a number of biological processes including cycle arrest, apoptosis, oxidative stress, cell migration and cell metabolism. Regulators of FoxO3, including phosphorylation, energy stress, genotoxic stress, and cytokines, control its abundance, subcellular localization and DNA-binding capacity. In this paper we study how the identities and concentrations of growth factors are encoded in the dynamics of FoxO3 activation. Transcription factors like FoxO3 often switch between on and off states repeatedly over the course of a 12-24 hours period. Immunoblotting and similar methods can obscure this switching behavior due to asynchronicity between cells. In contrast, our use of time-lapse microscopy of fluorescent reporter proteins reveals that FoxO3 exhibits complex low wavelength and pulsatile translocation dynamics responsive to combinatorial control by ERK and Akt with the potential to encode the identities and concentrations of multiple extracellular growth factors.
This dataset includes raw datasets either in .MAT, or .CSV for regenerating all figures in the publication. These folders should be placed inside the /rawdata folder in the git repository folder so that the reader can generate these figures on their own.
/parentalVSreporter - This dataset is used to regenerate fig.1B, S1B and S1C.
/Workspace - This dataset is important for all fPCA and pulse score analysis in Fig.1-6
