ACTA1 and cancer: Furthermore, a discrete proportion (0.5%) of EGFP/tdTomato double‐positive cells (with diminishing EGFP and emerging tdTomato expression) were also observed (Fig 2B), possibly reflecting retained EGFP proteins despite the start of tdTomato transcription in cancer cells at the onset of the αSMA‐Cre‐driven partial EMT phenotype.
