I need to perform some analysis of my data set with a public microarray dataset of serous epithelial ovarian cancer. I would like to have some insights about where I can get such datasets. I have extensively searched the Gene Expression Omnibus. My requirements are Stage IV serous epithelial ovarian cancer datasets. If I can get paired datasets , nothing like it but even if its not paired its not an issue but both normal and tumor samples should be profiled in the dataset. I have seen some Stage !V datasets but they do not have normal samples , I am typically looking for Stage IV microarray of serous epithelial OVa Cancer having samples from both normal and cancer patients. If anyone can give me some leads it would be helpful.
