I'm trying to read the data of GSE81608 from GEO, but I can't see the gene names. I tried both by reading the CSV file, and by using GOEquery from R. It looks like the gene names are not available. (the CSV just marks the genes by a running number) Is it possible that the dataset was published without the gene names? or am I missing something?

Well, it seems like the file was badly composed, perhaps. I couldn't get a proper Expression Matrix with GEOquery as well. 

Maybe can you get in touch with the authors?

Thanks!

I will update here if I find anything

If this is of interest to anyone, the gene annotation can be found here:
