Fig 5. Bi-allelic Perk deletion abolishes BrafV600ECA/+;Fbxo4+/- melanoma initiation, but Perk inhibition cannot recede tumor progression.

A) Kaplan-Mayer survival curve of BrafV600ECA/+, Fbxo4 +/- and Perk +/+, +/- or -/- mice treated with 4-Hydroxytamoxifen (4-HT). B) Western blot of melanoma lysates from TyrCreCA/+; BrafV600ECA/+; Fbxo4 +/-; Perk +/+, Perk+/- or Perk-/- mice C) IHC analysis of skin from TyrCre+/-;BrafV600ECA/+;Fbxo4 +/-; Perk+/+ or Perk -/- mice; H&E or IHC with antibodies for S100, p-eIF2α, Chop, cyclin D1, p-Akt, CD31 and quantification of staining/staining index (SI) of IHC. Scale bars = 50μm. D) Tumor volume in TyrCre+/-;BrafV600ECA/+;Pten-/- mice treated with LY-4; p-values analyzed by two-tailed Student t test. E-F) Western blot of melanoma skin lysates from TyrCre+/-; BrafV600ECA/+;Pten-/- mice treated with LY-4.
