Fig. 1From: Time-dependent antagonist-agonist switching in receptor tyrosine kinase-mediated signalingExperimental data from HC-11 murine mammary epithelial cell lines (reproduced with permission from Telesco et al. [8]). a Shows the RT-PCR results of the expression of the differentiation marker β-casein gene at three different time intervals (0–12, 12–24 and 24–48 h) for varying levels of ligand NRG stimulation. The results were compared with β-casein expression with Hydrocortisone (HC) as a control. b Shows the ELISA TF activation assays of the transcription factors STAT5 and Glucocorticoid Receptor (GR) at the nucleus at different time points post ligand stimulationBack to article page
