UASt regulatory sequences drive expression of an inverted repeat.
The failure of the midgut epithelium of Df(3L)AJ14/Df(3L)AJ14,armi+t6,CG14971+t4.2 mutant adults ('CycJ[&Grd;]' flies) to recover from Serratia marcescens infection-induced thinning is partially rescued by expression of lcsKK112522 under the control of Scer\GAL4NP3084 (together with tub-Gal80[ts] to limit the time of expression) in the mutant background.
