      Expression of spidsRNA.Scer\UAS.cUa in the midgut under the control of Scer\GAL80ts.αTub84B and Scer\GAL4esg-NP7397 does not affect midgut development and renewal, even after Pseudomonas entomophila infection.

      (Jiang et al., 2011)

      Expression of spiVDRC.cUa in precursor cells under the control of Scer\GAL4how-24B and Scer\GAL80ts.αTub84B results in reduced epithelial renewal and intestinal stem cell (ISC) proliferation after Erwinia carotovora carotovora 15 (Ecc15) infection compared with wild-type.

      (Buchon et al., 2010)

      Ectopic expression of spidsRNA.Scer\UAS.cUa driven by Scer\GAL4esg-NP7397 in adult midgut progenitor cells during larval development has no effect on their proliferation.

      Knockdown of spi through expression of spidsRNA.Scer\UAS.cUa in Df(3L)Krn-27-7-B mutant progenitor cells (under the control of Scer\GAL4esg-NP7397 and Scer\GAL80ts.αTub84B) significantly reduces midgut mitoses induced by Pseudomonas entomophila ingestion.
