SNAI2 and ductal breast carcinoma in situ: However, the extent to which unjamming and EMT, or partial EMT (pEMT), cooperate to facilitate tumor invasion remains poorly understood.[53] Therefore, we aimed to investigate whether the wetting in DCIS spheroids exhibits indicators of (p)EMT.[54] To explore this, we quantified the protein Slug, a known transcription factor that regulates the expression of genes involved in EMT in breast epithelium, including E‐cadherin, using Western blot analysis.
