Fig. 5 Sirolimus induces a durable cytostatic effect in <italic>nf1/pten</italic>-mutant melanomas.

a Representative tissue sections from a transplanted nf1/pten-mutant melanoma tumor at 4 days after a 6-day drug treatment with DMSO (CTR), 80 nM trametinib, 2 μM buparlisib, the combination of 80 nM trametinib and 2 μM buparlisib, or 20 μM sirolimus. Sections were immunostained using antibodies to detect pERK, pAKT, pS6, PCNA, and CC3. pERK-, pAKT- and pS6-positive tumor areas, as well as PCNA-positive nuclei, are quantified in (b–e). “T + B” refers to trametinib plus buparlisib. ns p > 0.05, *p < 0.05, **p < 0.01, ***p < 0.0001 by Mann–Whitney test. Scale bar = 20 μm.
