From these six genes two were higher expressed in GAMs derived from the RCAS model (CD300lf and Cd200r4), two genes were expressed at similar levels in GAMs in both tumor models (Trem1 and Sh2d1b1), and two genes were higher expressed in GAMs derived from the GL261 model (Uck2 and Creb5). Here, TREM1 is linked to neoplasm.
