Acute activation of ER-RAC1 P29S in melanocytes

We studied the effects of acute activation of the melanoma oncogene RAC1 P29S using a tamoxifen-inducible ER-fusion protein system in mouse melanocytes Overall design: An ER-RAC1 P29S fusion protein was stably expressed in the spontaneously immortalized mouse melanocyte cell line melan-a. The fusion protein was activated by treatment with 500 nM 4OH-tamoxifen. RNA was isolated and sequenced at 0 h, 4 h and 40 h post-treatment. The gene expression profiles at 4 h and 40 h were compared to the 0 h time-point. To control for effects induced by 4OH-tamoxifen independent from ER-RAC1 P29S, we performed the same experiment in melan-a cells transduced with an empty vector.
