Thanks John.

Seams interesting scientific stuff, still majority of it was already known (I didn't read full article so I may be bit out of line here) about Angio-x functions in neovascularization and tumor growth.

Investor do not buy, not anymore, this kind of story. What we need is clear statement from REGN: what is their business plan in regards the Angio-x proteins and how they will implement this plan???

In PRnews they wrote hints like:

<<In particular, our findings support drug development based on blocking VEGF action, which Regeneron and others are aggressively pursuing.>>

How they are blocking VEGF action??? What agent?

or

<<This may provide the opportunity to use Angiopoietin-2 as a diagnostic tool to allow imaging of small tumors and metastases, and perhaps even as a handle to allow targeting of chemotherapeutic agents specifically to tumor tissue.>>

Angio-2 + WHAT for imaging???
... and is TIE-2 selective (as natural Angio-2 receptor) expressed on tumor cells to allowed designee targeted Angio-2+chemo agents???
