Figure 9. Continuous Expression of Non-stop in ECs suppresses aging phenotypes in the midgut.
(A–N) Confocal images of the midgut tissue using the indicated antibodies and expressing the indicated transgenes in EC using the MyoIA-Gal4/Gal80ts. DAPI marks DNA and scale bar is 10 μM. (A, E, I, L) midguts derived from 2 to 4 days old flies (young) (B, F, J, M) Midguts derived from 5 weeks old flies expressing control (UAS-LacZ). (C, G, K, N) Midguts derived from 5 weeks old flies expressing UAS-Non-stop. DAPI marks DNA (blue), and scale bar is 10 μM. Arm, Armadillo; SSK Snakeskin. (D, H) Quantification of similar experiments shown in (A–C). **** = P < 0.0001, ***P < 0.001; **P<0.01; *=P<0.1 (O-R) Aging impairs gut integrity as evident by the leakage of blue-colored food into the abdomen (smurf assay). Continuous expression of Non-stop but not control using the MyoIA-Gal4/Gal80ts for five weeks safeguards gut integrity, n = 48, 38 respectively; P < 0.001.
