      Reference
      Scer\GAL4D59-mediated expression causes failure of salivary gland histolysis in 15 hour prepupae, the salivary glands can still be detected 22 hours after puparium formation. The salivary glands at this stage are abnormal in morphology and appear to be partially degraded.
      When expression is driven by Scer\GAL4cCa.T:Hsim\VP16 in mitotic domain 20 at gastrulation an expansion of the dorsal surface epithelium occurs, though cell death still occurs. Defects are mild compared to those of Df(3L)H99 embryos.
      Expression of BacA\p35Scer\UAS.cHa in the scutellum under the control of Scer\GAL4ptc-559.1, Scer\GAL4dpp.blk1 or Scer\GAL4sca-537.4 results in the formation of ectopic bristles.
      When expression is driven by Scer\GAL4fkh.PH salivary glands survive the cell death that would have been their normal fate. DNA fragmentation is suppressed, though they have progressed to a late stage of autophagy (i.e. vacuoles and associated plasma membranes are often absent from the cytosol).
      Embryos expressing BacA\p35 using Scer\GAL469B with BacA\p35Scer\UAS.cHa have severe head defects, while denticle patterning appears fairly normal. Cell death is completely blocked in these embryos.
      BacA\p35Scer\UAS.cHa; Scer\GAL4C-765 flies have no discernible wing phenotype. BacA\p35Scer\UAS.cHa; Scer\GAL4GMR.PF flies have subtle ommatidial disorganisation.
      In BacA\p35Scer\UAS.cHa; Scer\GAL4arm.PS embryos, an ectopic external sensory organ forms near the abdominal ventral multidendritic neuron a1 neuron in many abdominal segments.
      Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4GMR.PF results in extra interommatidial cells in the eye disc.
      Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4neur-P72 produces supernumerary polar cells in advanced egg chambers. Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4Act5C.PP in clones in the egg chamber results in the production of extra polar cells. No obvious defects are seen in the early development of these egg chambers. 80% of stage 9 egg chambers expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4Act5C.PP have round anterior follicle cells, a constant thickness of epithelial cells along the anterior-posterior axis and a homogeneous distribution of anterior follicle cell nuclei (in contrast to wild-type stage 9 egg chambers which have elongated anterior follicle cells, thinning of the epithelium at the anterior end and a reduction in density of follicle cell nuclei at the anterior pole). 91% of stage 10 egg chambers expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4Act5C.PP have defects in delamination and migration of border cells; the border cells are either still stuck at the anterior pole or are only partway between the anterior pole and the oocyte. These clusters often contain supernumerary border cells.
      Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4Cg.PA does not cause an appreciable increase in hemocyte number in third instar larvae.
      When BacA\p35Scer\UAS.cHa is expressed under the control of Scer\GAL4sim.PS an increase in the number of midline glial cells is seen. About 6 cells are seen per neuromere.
      Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4pnr-MD237 results in extra macrochaetae in the scutellum in 30% of animals.
      Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4neur-P72 suppresses the fragmentation of the glial cell which is normally seen in the thoracic microchaete lineage in the developing notum; at 24 hours after puparium formation (APF), 86% of the clusters contain glial cells in these animals (compared to 8% of clusters in control animals). The ectopically surviving glial cells are tightly associated with axonal processes in 72% of sensory organs studied at 24 hours APF (in 55% of cases the glial cells are located at the growth cone, while in the remaining 17.5% they are associated with the axon), while in 27.5% of the sensory organs studied the glial cells remain within the proximity of the cluster. At 27 hours APF, the axonal network of the notum and its orientation shows no major difference between wild-type pupae and pupae expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4neur-P72. Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4neur-P72 promotes precocious axonogenesis; axonal growth cones of notal microchaetae are observed 23.5 hours APF in these flies, compared to 25 hours APF in wild type. The cleaning reflex is normal in adults expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4neur-P72.
      When driven by Scer\GAL4OK107 or Scer\GAL4Tab2-201Y no defects in axon pruning or the mushroom body are seen.
      When BacA\p35Scer\UAS.cHa is driven by Scer\GAL4αTub84B.PL in scrib1 clones in the eye, the amount of mutant tissue surviving to adulthood increases compared with scrib1 clones alone.
      When BacA\p35Scer\UAS.cHa is driven by Scer\GAL4Dll-981 in the antennal disc >300 glial cells are formed as opposed to the ~100 in wild-type. The organisation of sensory afferent fascicles from the antenna is unaffected. When BacA\p35Scer\UAS.cHa is driven by Scer\GAL4lz-gal4 in the antennal disc a significant increase in glial cell number is seen. When BacA\p35Scer\UAS.cHa is driven by Scer\GAL4pros.PMG in the antennal disc a significant increase in glial cell number is seen. When BacA\p35Scer\UAS.cHa is driven by Scer\GAL4ato.3.6 in the antennal disc no alteration is seen in the number of glial cells. When BacA\p35Scer\UAS.cHa is driven by Scer\GAL4hs.PB and heat pulsed up to 6-8 hours after puparium formation (AFP) no significant alterations in glial number are seen. While pulsing during the 14 to 18 AFP period results in a very large increase in glial cell numbers.
      When BacA\p35Scer\UAS.cHa is driven in the wing disc by Scer\GAL4C10, no effect on the average size of the wing disc is seen. However significantly variability is in the size of the wing disc.
      BacA\p35Scer\UAS.cHa; Scer\GAL4Hsp83.PA males are infertile (males carrying either construct alone are not). Although the initial assembly of the "individualisation complex" at the head of the cyst appears normal, there is a failure of cytoplasm to collect into a normal cystic bulge.
      In the wings of BacA\p35Scer\UAS.cHa; Scer\GAL4en-e16E flies many cells persist between the dorsal and ventral cuticular sheets.
      Apoptosis is eliminated and extra photoreceptor clusters are formed at the edge of the developing eye in BacA\p35Scer\UAS.cHa; Scer\GAL4GMR.PF animals 42 hours after puparium formation. These clusters survive to form ommatidia in adult flies, but are often incomplete.
      Cell proliferation is not increased in the posterior compartment of wing discs expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4en-e16E. Wings appear normal in adults expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4en-e16E.
      Expression of BacA\p35Scer\UAS.cHa, driven by Scer\GAL4Ddc.PL, results in a statistically significant increase in the number of both serotonergic and dopaminergic neurons after metamorphosis.
      In stage 16 female gonads, where expression of BacA\p35Scer\UAS.cHa is driven by both Scer\GAL4how-24B and Scer\GAL4twi.PB, these gonads appear masculinized; male-specific somatic gonadal precursors persist and join the posterior of female gonads, as in wild-type male embryos. The presence of such cells does not appear to affect ovary formation or oogenesis, since embryos develop into fertile adult females.
      BacA\p35Scer\UAS.cHa; Scer\GAL4nub-AC-62 suppresses basal levels of apoptosis in the wing pouch.
      Flies expressing BacA\p35Scer\UAS.cHa under the control of one of Scer\GAL4nub-AC-62, Scer\GAL4ap-md544, Scer\GAL4hh-Gal4 or Scer\GAL4en-e16E have virtually normal wings. Wing vein L5 is slightly shortened in animals expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4hh-Gal4. Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4ap-md544 prevents wing death in the dorsal, but not the ventral, compartment of the wing disc. Animals expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4hh-Gal4 which have been irradiated during the first larval instar show defects in the wing disc; the posterior compartment is abnormal in shape and increased in size. The few adults that do hatch differentiate wings with very abnormal and overgrown posterior compartments. Wing discs of animals expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4hh-Gal4 which have been irradiated during the first or second larval instar show an increase in the ratio of the size of the posterior compartment/anterior compartment compared to control discs and show greater BrdU incorporation in the posterior compartment after irradiation. In addition, cells in the anterior compartment close to the anterior-posterior (AP) border also show an increase in BrdU incorporation. The AP border becomes highly irregular in these irradiated discs and cells of posterior provenance often penetrate into the anterior compartment. These invading posterior cells do not readily mix with anterior ones, but tend to stay in separate groups. Clones in the wing disc expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4Act5C.PI which have been induced during the first or second larval instar and then irradiated 24 hours later, show heterogeneous incorporation of BrdU inside the clone. There is often an increase of BrdU levels in the vicinity of these clones.
      Expression of BacA\p35Scer\UAS.cHa under the control of Scer\GAL4Vap.P0201 efficiently suppresses the cell death that is normally seen in anterior dMP2 neurons in late stage embryos, such that these neurons are present in late stage embryos.
      Males show rotated terminalia and a gap in the dorsal midline.
      X-ray irradiated wing disc clones expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4tub contain a mixture of two types of cell: `live' cells, which have not initiated apoptosis due to the irradiation, and `undead' cells (between 20 and 70% of the clone), which have initiated apoptosis, but have failed to complete programmed cell death. No such cells persist outside the clones in which BacA\p35Scer\UAS.cHa is expressed. The `live' cells in the X-ray irradiated clones display increased proliferation, while the `undead' cells exhibit an abnormally slow rate of proliferation. X-ray irradiated wing disc clones expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4tub are also associated with local enhancements of growth, with approximately 43% of wing discs exhibiting local deformations and small outpouchings of extra tissues associated with the clones.
      Expression of BacA\p35Scer\UAS.cHa, under the control of Scer\GAL4en-e16E leads to vein loss in the adult wing.
      Expression of BacA\p35Scer\UAS.cHa in the posterior of the wing disc, driven by Scer\GAL4en-e16E, has little effect on the patterning of adult wings.
      Inhibition of caspases in the scutellum, achieved by expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4sca-P309, results in the formation of ectopic macrochaetae on this body part in 39% of cases. Ectopic macrochaetae also appear in 23% of cases when BacA\p35Scer\UAS.cHa is expressed under the control of Scer\GAL4dpp.blk1. In contrast, the ectopic expression of BacA\p35Scer\UAS.cHa in SOP cells, driven by Scer\GAL4neur-GAL4-A101, does not result in extra macrochaetae. No significant increase in macrochaetae number is seen when BacA\p35Scer\UAS.cHa is expressed under the control of Scer\GAL4hs.PB following a heat shock at late third-instar (6-12 h APF), which is during SOP cell formation, or after it (24-30 h APF). At the stage prior to the appearance SOP cells, however, BacA\p35Scer\UAS.cHa expression leads to extra macrochaetae formation.
      Expression of BacA\p35[Scer\UAS.cHa] under the control of Scer\GAL4[Crz] rescues apoptosis of Crz-expressing neurons in the ventral nerve cord during pupation.
      Expression of BacA\p35[Scer\UAS.cHa], under the control of Scer\GAL4[elav-C155], does not increase lifespan in flies.
      Expression of BacA\p35[Scer\UAS.cHa], under the control of Scer\GAL4[en-e16E], results in misorientation of male external genitalia, while Scer\GAL4[ptc-559.1]-driven expression leads to an increased number of bristles. Over 96% of wings in Scer\GAL4[en-e16E]>BacA\p35[Scer\UAS.cHa] flies appear normal.
      Expression of BacA\p35[Scer\UAS.cHa] under the control of Scer\GAL4[Act5C.PI] does not affect S2 cell morphology.
      Flies expressing BacA\p35[Scer\UAS.cHa] under the control of Scer\GAL4[Mhc.PW] show normal wing positions.
      Expression of BacA\p35[Scer\UAS.cHa] under the control of Scer\GAL4[ey.PH] in wild-type eyes does not affect eye size.
      Expression of BacA\p35[Scer\UAS.cHa] under the control of Scer\GAL4[dpp.blk1] in the wing disc has no effect on cell morphology.
      Blocking apoptosis in larval epidermal cells by clonal expression of BacA\p35[Scer\UAS.cHa], under the control of Scer\GAL4[Act5C.PI], results in impaired extrusion of these cells from the epidermis, and failure of haemocyte recruitment and the engulfment process. The few larval epidermal cells that are able to undergo extrusion remain as viable cells under the epithelial layer. Concomitantly, there is a significant decrease in the progression of histoblast nest spreading and in the average number of histoblasts. Some of these animals survive to pharate adults, but survivors show abdominal cuticle clefts with many larval epidermal cells still present.
      Expression of BacA\p35[Scer\UAS.cHa] under the control of Scer\GAL4[109-53] results in an abnormal stalk between egg chambers. The stalk contains more cells than normal and the cells are not properly arranged into a one-cell wide stalk.
      At 24 hours after puparium formation, animals expressing BacA\p35[Scer\UAS.cHa] under the control of Scer\GAL4[fkh.PH] still contain salivary gland tissue, in contrast to wild-type animals, where the salivary glands have completely degraded by this stage.
