Epithelial organization, cell polarity and tumorigenesis

LM McCaffrey, IG Macara - Trends in cell biology, 2011‏ - cell.com
Epithelial cells comprise the foundation for the majority of organs in the mammalian body,

Loss of the Par3 polarity protein promotes breast tumorigenesis and metastasis

LM McCaffrey, JA Montalbano, C Mihai, IG Macara - Cancer cell, 2012‏ - cell.com
Loss of epithelial organization is a hallmark of carcinomas, but whether polarity regulates
tumor growth and metastasis is poorly understood. To address this issue, we depleted the …

The PAR proteins: from molecular circuits to dynamic self-stabilizing cell polarity

CF Lang, E Munro - Development, 2017‏ - journals.biologists.com
PAR proteins constitute a highly conserved network of scaffolding proteins, adaptors and
