Perhaps you should try some spelling variations:
methylation patterns » migration patterns (Expand search)
decrease methylation » decrease migration (Expand search), accurate methylation (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease AND decrease will decrease ) OR ( decrease costs decrease methylation patterns ))~.
