GLP-1 signaling regulates MSP-dependent cytoplasmic streaming. (A) Measurements of cytoplasmic flow rates (DIC particle speed) at 16-20 hours post-L4 in glp-1 mutant backgrounds. glp-1(rf) mutations increase flow; glp-1(gf) mutations decrease flow. Flow rates were also analyzed at the same timepoints in the other genetic backgrounds and experimental treatments, except oil injections were also analyzed 12 hours post-injection. (B) MSP is sufficient to cause elevated flow rates in glp-1 mutant females. Hermaphrodites or unmated fog-2 females were analyzed 1 hour after MSP injection or mating. Flow rates were compared with the wild type: *P<0.001; #P<0.01; ‡P<0.05.
