medical news: Sequence of ovarian genome identifies predominant gene mutations, points to possible treatment

"....While high-grade serous ovarian adenocarcinoma is conventionally considered as one type of cancer having uniform features, "we could divide the tumors into four different groups based on gene expression patterns," said Creighton. "They look like four different cancers."
"We were able to define a set of genes that were associated with worse outcomes versus better outcomes in patients," he said. They applied this gene signature to other sets of data collected about ovarian cancer and found that the profile predicted worse or better outcome there as well.
"These data are all public (blogger's note - refers to the Cancer Genome Atlas)," said Creighton. "They are meant for people to use to find specific genes for research. They could influence a lot of future studies."...cont'd
