Effect of Bap55 RNAi on E(spl) mβ-HLH (mβ) and E(spl) m3-HLH (m3) expression levels measured by reverse transcription-qPCR in Notch-OFF (PBS treatment) and Notch-ON (EGTA treatment) conditions. Expression level of RpII215 is shown as a control gene. Mean +/- SEM; n = 3; * p<0.05 with one-tailed student's t-test compared to lacZ RNAi control.
