In individuals with injured gut at late L3W (by the expression of rprUAS.cCb), the expression of fzrUAS.cSa under the control of Scer\GAL4byn-Gal4 leads to decreased adult pyloric cell number; cell show increased nuclear size.

In individuals with injured gut as adults (by the expression of rprUAS.cCb), the expression of fzrUAS.cSa under the control of Scer\GAL4byn-Gal4 leads to increased pyloric cell number.

Expression of rapScer\UAS.cSa under the control of Scer\GAL4repo.PU or Scer\GAL4c527 results in a dramatic reduction in glial cell number in the eye disc.

Expression of rapScer\UAS.cSa under the control of Scer\GAL4Mz97 has no effect on glial cells in the eye disc.

Expression of rapScer\UAS.cSa under the control of Scer\GAL4prd.RG1 causes inhibition of mitosis 16 in the rapScer\UAS.cSa-expressing embryonic segments.

Expression of rapScer\UAS.cSa in the developing eye, under the control of Scer\GAL4ey.PH, causes three distinct phenotypes: 1. Inhibition of compound eye development. The severity of this ranges from a drastic reduction of the eye to a complete loss of the eye. 2. Induction of ectopic antennae. These antennae can appear fully-differentiated, or may consist of only the first antennal segment. They can occur at the eye position or surrounding regions of the head. Staining of the eye-antennal disc with antennal-specific markers suggests that this ectopic formation is due to an increase in size of the antennal primordia. 3. Induction of abnormally large cells in the eye and more medial regions of the head that form tumour-like structures.

In somatic clones of rapScer\UAS.cSa; Scer\GAL4Act5C.PP cells in the ovarian follicle cells, mitosis arrests (indicated by loss of expression of some mitotic markers) and nuclei become enlarged. FACS profiles of DNA content in follicle cell populations containing these somatic clones show a 32n population not present in wild-type. However, amplification at specific loci (seen after stage 10B in wild-type) occurs normally in these enlarge nuclei.

When rapScer\UAS.cSa is driven by Scer\GAL4twi.PG, most hemisegments of mutant embryos show only one eve expressing pericardial cell (EPC), suggesting that the last division generating two EPCs did not occur. Only four (instead of the normal six) myocardial cells form per hemisegment.

In rapScer\UAS.cSa; Scer\GAL4prd.RG1 embryos, cells in alternate segments fail to execute mitotic cycle 16, resulting in fewer cells per segment in embryos older than stage 12.

Mitosis 16 is blocked in embryos expressing rapScer\UAS.cSa under the control of Scer\GAL4prd.RG1. Inhibits mitotic divisions during imaginal disc cell proliferation when expressed in the posterior compartment of the imaginal discs using Scer\GAL4en-e16E, with the cells undergoing DNA overreplication.

Coexpression of CycAScer\UAS.cWa with rapScer\UAS.cSa, under the control of Scer\GAL4prd.RG1, suppresses the inhibition of embryonic mitosis 16 seen when rapScer\UAS.cSa is expressed alone.

Rca1Scer\UAS.T:Ivir\HA1 suppresses the embryonic cycle 16 mitotic block due to a rapScer\UAS.cSa; Scer\GAL4prd.RG1.

Embryos expressing both CycEScer\UAS.cLa and rapScer\UAS.cSa under the control of Scer\GAL4prd.RG1 show normal development until and including mitosis 16 followed by an extra division cycle. Results in an inhibition of mitosis when expressed in CycEAR95 embryos using Scer\GAL4prd.RG1.

Complementation and Rescue Data
Comments

Expression of rapScer\UAS.cSa under the control of either Scer\GAL4gcm.PU or Scer\GAL4repo.PU fails to rescue the increase in glial cell number and glial cell migration defects seen in rapie28 embryos.

Expression of rapScer\UAS.cSa under the control of Scer\GAL4elav-C155 does not rescue the increase in glial cell number seen in rapie28 embryos, but the glial cell migration defect is completely rescued in 49.6% of hemisegments and is partially rescued in 25.9% of hemisegments. The axonal growth defects seen in the central and peripheral nervous systems are also rescued.

Expression of rapScer\UAS.cSa under the control of Scer\GAL4elav.PLu almost completely rescues both the glial cell migration defects (71.5% complete rescue, 19% partial rescue) and increase in glial cell number seen in rapie28 embryos. The axonal growth defects seen in the central and peripheral nervous systems are also rescued.

Expression of rapScer\UAS.cSa, under the control of Scer\GAL4drl-PGAL8, fully rescues the rough eye phenotype in 67% of flies and mediates a partial rescue in the other 33%.
