Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
different effects » differential effects (Expand search)
create different » creates different (Expand search), creates difference (Expand search), creating different (Expand search)
response create » response rate (Expand search), response decrease (Expand search), response increase (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
decrease pro » decrease or (Expand search), decrease food (Expand search), decrease treg (Expand search)
pro decrease » to decrease (Expand search), or decrease (Expand search), price decrease (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 akt decrease pro decrease ) OR ( decrease response create different effects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease pro decrease ) OR ( decrease response create different effects ))*.
