Expression of hidhs.PG results in rapid male germline stem cell loss.

Expression of hidhs.PG results in rapid and robust cell death of 100% of mitotically cycling follicle cells in the ovary. Induction of hidhs.PG during endocycles does not result in follicle cell death.

Expression of hidhs.PG in early third-instar larvae causes rapid apoptosis (caspase activation) in mitotically cycling cells of the wing disc, eye disc and brain. No caspase labelling is seen when hidhs.PG is expressed in endocycling salivary gland cells or in the fat body.

Expression of Whs.PG following a 1 hour heat shock induces apoptosis throughout the wing disc.

Causes apoptosis leading to organismal death in the embryo, when heat shock is applied at 5-10 hours after egg laying.

Only 2% of animals survive to adulthood after a 30 min heat shock at 37oC during the first larval instar. A 40 minute heat shock kills all animals.

Overexpression of W induces apoptosis. Heat treatment in third instar larvae is followed by the appearance of apoptotic cells in the intervein territories, treatment of pupal wings causes all the cells to undergo apoptosis.

High levels of programmed cell death (PCD) are observed 2 hours after Df(3L)H99 embryos carrying P{hs-hid} have been heat shocked. Death appeared to occur by apoptosis. Induced ectopic cell death in wild type embryos is lethal. This lethality is not augmented by the presence of endogenous rpr.

Genetic Interactions
Statement
Reference

Co-expression of hidhs.PG and grimhs.PC in endocycling salivary gland cells results in a higher level of apoptosis (caspase activation) compared to the expression of either transgene alone. No apoptosis is observed in the fat body.

Organismal death in the embryo, caused by Whs.PG when heat shock is applied at 5-10 hours after egg laying is enhanced by thSL and suppressed by th6B. thSL slightly enhances Whs.PG-induced adult inviability, whereas th6B increases the viability of Whs.PG flies threefold.

The Gap121-1s, sty28-4s, argosΔ7 and rlSem mutants counteract the lethality caused by Whs.PG.

Comments

A genomic cosmid clone containing the transcribed region of W was constructed but failed to rescue W mutants. This is presumably due to the large size of the W transcription unit, 5' sequences required for W expression are presumed to be absent.

Heat shock protocol for killing animals carrying P{hs-hid}: -let parents lay for 5 days in vials at room temp or 25C -remove parents -heat shock for 2 hrs. at 37C in a water bath on day 5 -repeat heat shock on day 6 Heat shock must be performed in a water bath, not an air incubator for heat shock induction to be successful with this allele.
