Detailed Description
Statement
Reference

Tnks19/Tnks503 transheterozygous mutants eclose at normal rates and are viable, but adults display a significant increase in mortality when maintained on a sucrose only diet (5% sucrose (v/v) in aqueous solution), as compared to controls.

Tnks19/Tnks503 transheterozygous mutant adult midguts show a significant increase in the numbers of intestinal stem cells, of intestinal progenitor cells and of mitotic cells, but similar apoptotic levels, as compared to controls; these phenotypes become more severe with age.

Adulthood-generated Tnks19 homozygous somatic clones in mosaic midguts have a significant increase in cell number as compared to adulthood-generated control somatic clones in wild-type adult midguts but, similarly to wild-type clones, these clones include enteroblasts, enterocytes and enteroendocrine cells.

Generating Tnks19 homozygous somatic clones in mosaic midguts during adulthood leads to an increase in the number of neighboring control intestinal progenitor cells, heterozygous for Tnks19; this phenotype is not seen in clones generated during pupation and analyzed at eclosion.

Statement
Reference

The increase in the numbers of intestinal progenitor cells and mitotic cells present in Tnks19/Tnks503 transheterozygous mutant adult midguts is suppressed by AxnS044230 heterozygosity; the increase in the numbers of intestinal stem cells and mitotic cells observed in Tnks19/Tnks503 transheterozygous mutant adult midguts are suppressed by expressing either upd3KK110348 or upd3GD6811 under the control of Scer\GAL4Myo31DF-NP0001.

Adulthood-generated Tnks19, AxnS044230 double homozygous somatic clones expressing the AxnT:SV5\V5 rescue transgene present a significant decrease in cell number as compared to adulthood-generated Tnks19 single homozygous somatic clones.

Expression of AxnScer\UAS.T:SV5\V5 under the control of Scer\GAL471B in the Tnks19/Tnks503 background leads to morphological wing (notches, loss of wing margin, ectopic bristles) and ventral abdomen (loss of sternite and sternite bristles, reduced size of the sternites that remained, expansion of pleura) defects in adults.

Comments

Expressing TnksScer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Myo31DF-NP0001 significantly rescues the increase in the numbers of stem cells and mitotic cells observed in the adult midgut of Tnks19/Tnks503 transheterozygous mutant adults.
