20xUAS regulatory sequences drive expression of Hsap\LIN28B which is tagged at the C-terminal end with three copies of Tag:FLAG and then three copies of Tag:HA.
Expressing Hsap\LIN28B20xUAS.Tag:FLAG,Tag:HA under the control of Scer\GAL4αTub84B.PL results in a severely delayed onset of pupariation compared to wild-type controls.
Expressing Hsap\LIN28B20xUAS.Tag:FLAG,Tag:HA under the control of Scer\GAL4Act5C.PI has no impact on pupal volume compared to wild-type controls.
Expression of Hsap\LIN28B20xScer\UAS.T:Zzzz\FLAG,T:Ivir\HA1 under the control of Scer\GAL4esg.PU in adult intestinal stem cells (ISCs) and enteroblasts for two days (using the temperature sensitive Scer\GAL80ts.αTub84B line to control the timing of expression) does not result in a significant change in the total number of ISCs in the posterior midgut compared to in controls.
