hub cell | progressive, with Scer\GAL4C833
Expression of shvScer\UAS.T:Ivir\HA1 under the control of either Scer\GAL4nSyb.PS or Scer\GAL4how-24B does not perturb synaptic growth as the number of boutons as well as immature, undifferentiated 'ghost boutons' on the neuromuscular junctions in third instar larvae is comparable to controls. Scer\GAL4nSyb.PS-driven expression of shvScer\UAS.T:Ivir\HA1 also has no significant effect on the amplitude of either miniature or evoked excitatory postsynaptic potentials.
Expression of shvScer\UAS.cLa driven in hub and cyst cells by Scer\GAL4C833 does not significantly affect hub cell number (up to 35 days old) but does significantly decrease germline stem cell number (at 3, 7, 14, 35 and 50 days post eclosion) in the testes compared to controls. Expression of shvScer\UAS.cLa driven in hub cells by Scer\GAL4upd1.PU does not significantly affect hub cell number (up to 35 days old) in the testes compared to controls. Expression of shvScer\UAS.cLa driven in germ cells by Scer\GAL4nos.UTR.T:Hsim\VP16 does not significantly affect the number of germline stem cells per testes (up to 35 days old) but does significantly increase the number of hub cells at 3 and 50 days post eclosion (but not 7, 14 or 35 days) compared to controls.
Expression of shvScer\UAS.cLa driven by Scer\GAL4C833, Scer\GAL4nos.UTR.T:Hsim\VP16 or Scer\GAL4upd1.PU increases hub cell number per testes in 50 day old flies compared to controls. Expression of shvScer\UAS.cLa driven by Scer\GAL4upd1.PU increases germline stem cell number per testes in 50 day old flies compared to controls.
shvUAS.Tag:HA/Scer\GAL4nSyb.PS is a suppressor of abnormal neuroanatomy | third instar larval stage phenotype of mysts1
Scer\GAL4how-24B/shvUAS.Tag:HA is a non-suppressor of abnormal neuroanatomy | third instar larval stage phenotype of mysts1
shvUAS.Tag:HA/Scer\GAL4nSyb.PS is a suppressor of NMJ bouton | third instar larval stage phenotype of mysts1
Scer\GAL4how-24B/shvUAS.Tag:HA is a non-suppressor of NMJ bouton | third instar larval stage phenotype of mysts1
Expression of shvScer\UAS.T:Ivir\HA1 under the control of Scer\GAL4nSyb.PS (but not Scer\GAL4how-24B) rescues the increased number of boutons on neuromuscular junctions characteristic for mysts1 mutant third instar larvae.
shvUAS.Tag:HA/Scer\GAL4C833 rescues shv1
Scer\GAL4C587/shvUAS.Tag:HA rescues shv1
Scer\GAL4VP16.nanos.UTR/shvUAS.Tag:HA partially rescues shv1
Scer\GAL4how-24B/shvUAS.Tag:HA fails to rescue shv1
shvUAS.Tag:HA/Scer\GAL4upd1.PU fails to rescue shv1
Expression of shvScer\UAS.T:Ivir\HA1 under the control of Scer\GAL4nSyb.PS (but not Scer\GAL4how-24B) rescues the increased number of boutons on neuromuscular junctions as well as the decreased miniature excitatory postsynaptic potential amplitude observed in shv1 mutant third instar larvae.
Expression of shvScer\UAS.cLa driven in hub and cyst cells by Scer\GAL4C833 rescues hub integrity and germline stem cell number (at all ages tested), along with rescuing hub mislocalization, in shv1/shv1 testes. Expression of shvScer\UAS.cLa driven by Scer\GAL4C587 rescues hub integrity and germline stem cell number in shv1/shv1 testes. Expression of shvScer\UAS.cLa driven in hub cells by Scer\GAL4upd1.PU fails to rescue and indeed exacerbates hub integrity in shv1/shv1 testes (at all ages tested). Expression of shvScer\UAS.cLa driven in germ cells by Scer\GAL4nos.UTR.T:Hsim\VP16 partially preserves the hub (at all ages) and protects against decreases in germline stem cell number (except by day 35) in shv1/shv1 testes.
