Why the study?
While RGS10 and RGS18 had each been studied individually, critical questions remained regarding the overall impact of RGS-mediated regulation in platelets.
Does the combined deletion of RGS10 and RGS18 affect platelet activation, production, and survival in mice?
Population
Mice missing RGS10, RGS18, or both (RGS10-/-18-/-)
Comparison
RGS10-/-18-/- mice vs individual knockouts (RGS10-/- and RGS18-/-)
Design
Preclinical animal study
Key result
Mice missing both RGS10 and RGS18 showed reduced platelet survival, a 40% decrease in platelet count, and an exaggerated response to injury compared to single knockouts.

Dual RGS10/RGS18 deletion impairs platelet survival in mice; hypothesis-generating for complementary regulation, with human relevance untested.
Does the combined deletion of RGS10 and RGS18 affect platelet activation, production, and survival in mice?
RGS10 and RGS18 have complementary roles in regulating platelet reactivity, production, and survival in vivo.
DeHelian et al. (2020) studied Platelet activation and survival. RGS10 and RGS18 double knockout vs. Single knockouts (RGS10-/-, RGS18-/-) and wild type was evaluated on Platelet count, survival, and reactivity. Mice missing both RGS10 and RGS18 showed reduced platelet survival, a 40% decrease in platelet count, and an exaggerated response to injury compared to single knockouts.
