Perhaps you should try some spelling variations:
decreased expression » increased expression (Expand search)
expression process » expression precedes (Expand search), compression process (Expand search), expansion process (Expand search)
during decreased » during increased (Expand search), during depressed (Expand search), drinking decreased (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » the decrease (Expand search), not decrease (Expand search), of decrease (Expand search)
decrease to » decreased to (Expand search), decrease the (Expand search), decrease pro (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease to decrease toc decrease ) OR ( decrease during decreased expression process ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease toc decrease ) OR ( decrease during decreased expression process ))*.
