Cadherin control of invasive growth in morphogenesis and cancer

Objetivo

Cadherin-based cell-cell junctions regulate tissue architecture by coordinating multicellular growth and polarity. In addition to the ubiquitously expressed and widely studied E-cadherin, epithelia express other, more tissue-specific classical cadherins, often particularly during developmental epithelial rearrangements. These additional cadherins recently also have been implicated in tumor progression, but their expression and function is poorly understood.

I recently demonstrated that different classical cadherin subtypes have distinct roles in branching morphogenesis. I hypothesize that cell-cell junction control in invasive growth of developmental branching morphogenesis is recapitulated in collective cancer invasion, where tumor cells invade as strands that maintain cadherin-based cell-cell contacts. The aim is therefore to determine how stage-dependent regulation of distinct cadherins control these processes, using the following objectives:

1. To test that co-expression of E-cadherin and other cadherins control cell migration and rearrangement of the extracellular matrix and, thus, invasive physiological growth.

2. To define the role of co-expressed cadherins in collective invasive growth and resistance in cancer.

To demonstrate how cadherins accessory to E-cadherin control physiological collective invasion and growth, and how this is recapitulated in an aberrant fashion during invasive growth of epithelial cancers, I will contrast models for branching morphogenesis of kidney and mammary epithelium to neoplastic invasion of kidney and breast cancer cells.
