Snail1 has been reported to be involved in the renal epithelial-mesenchymal transition (EMT), which leads me to raise the following two questions:

1. Can we induce mesenchymal-epithelial transition by regulating human Snail1 expression?

2. Does human Snail4 exist?

Addendum primum:

The notion of EMT seems as important as ever.

Addendum secundum:

Is mesenchymal-epithelial transition similar to EMT?
