The interaction of recombination proteins with supercoiled DNA: defining the role of supercoiling in lambda integrative recombination.

abstract：:Subsets of long-lived, tumor-initiating stem cells often escape cancer therapies. However, sources and mechanisms that generate tumor heterogeneity and drug-resistant cell population are still unfolding. Here, we devise a functional reporter system to lineage trace and/or genetic ablate signaling in TGF-β-activated sq...
