Figure 5. Riluzole-induced Smad linker phosphorylation is independent of GRM1 expression level in melanoma cells. A.

Immunoblot with lysates from UACC903-V1 (V1) cells and two clones overexpressing GRM1, called UACC903-G2 and UACC903-G4 (abbreviated as G2 and G4 respectively). B. Riluzole-induced Smad2 and Smad3 linker phosphorylation in V1, G2 and G4 cells.
