Constitutive activation of protein S6 kinase, 90 kDa, polypeptide 1 (RSK1) accelerates melanoma tumor onset and invasion in zebrafish. A: Melanoma-free survival curve of miniCoopR-green fluorescent protein (GFP)-, miniCoopR-Myr-RSK1-, and miniCoopR-RSK-deltaCCT-injected zebrafish. B: Histologic sections of zebrafish RSK1dCCT- and Myr-RSK1-expressing melanomas were stained with hematoxylin and eosin to assess tumor invasion depth. Arrows indicate muscular invasion by melanoma cells. C: Depth of invasion was measured for each tumor and was quantified by averaging the depth of invasion of four tumors for each group (RSK1dCCT and Myr-RSK1). Data are given as means ± SEM. ***P < 0.001 compared with dominant-negative RSK1-expressing tumors.
