  sub:_5 prov:value """In agreement with this, antibody-mediated TNFR1 blockade significantly inhibited s.c.
tumor growth of three independent SCC tumor lines, A431, SCC25, and CAL27 (Supplementary
Fig. S8A). To determine if TNFR1 action in this context is tumor cell
intrinsic, we used retroviral-mediated RNA interference to decrease TNFR1 expression.
Reduced levels of TNFR1, as confirmed by immunoblotting, significantly
inhibited s.c. growth of Ras-driven tumors and SCC lines (Supplementary Fig. S8B).""" ;
