Does anybody know where I can find time series gene expression datasets for cancer cell lines? There are available datasets in CCLE or GDSC but as far as I know they are not time series data. 

Thanks in advance,

Usually you would go to or if you are interested in public gene expression data sets. Have you tried searching for cancer AND time? I don't think they have a distinct tag for time-series, but you would be able to pick up something.

I did actually, but could not come up with something useful as mostly either the data is small or it is not time-series. Thanks,

I am curious why you want that. You are looking at cancer cell lines. These have been selected to be stable growing cells, right? In other words a time series, without any intervention, should ideally not show any effect at all.

I was thinking that a time-series data allows me to infer protein networks, as it will show the change of gene expression over time for all genes. Therefore I will be able able to compute the correlations between genes, infer a gene network for each cell line, then see the differences between cell lines in terms of their protein/gene networks.

Ahh right. That should work only if the cell growth has been synchronised somehow, which can be done. See for instance:

hello. i have the same issue. Did you find your answer eventually? If so it would be a great help!

Hello! I also have the same exact issue - if you or Andrea found good data sources please let me know! Many thanks!
