YAP1 and neoplasm: Since the TONDU-containing proteins Vg (Khan et al., 2013) and Tgi (Guo et al., 2013; Koontz et al., 2013) can inhibit Yki-regulated growth by competing for Sd, we tested whether co-expression of TONDU peptide alone (CVVFTNYSGDTASQVDEHFSRALNY) in ISCs with gain of Yki (esgts>yki3SA UAS-vgTONDU) would inhibit Yki-driven ISC tumor growth.
