Acquired resistance to BRAF inhibitors mediated by a RAF kinase switch in melanoma can be overcome by cotargeting MEK, IGF-1R/PI3K. development of resistance to MEK inhibitors. These proteins could provide an opportunity to develop markers and restorative targets inside a subgroup of triple bad breast tumor (TNBC) that show resistance against MEK inhibition. , Therefore, we tested if inhibition of ERK signaling would decrease the manifestation of several lung metastasis signature genes in BoM2 and BrM2 cells (Number ?(Figure1B).1B). Cells were treated with the MEK inhibitor UO126 and analyzed using RT-PCR. Treatment of cells with UO126 resulted in down-regulation of fwd, 5-GATGGGAGGCAAGTTGAAA A-3; rev, 5-CTGGTTGAAAAGCATGAGCA-3; fwd, 5-GAAAGCTTGCCTCAATCCTG-3; rev, 5-CCCTGCCTTCACAATGATCT-3; fwd, 5-TGCTGTGGAGCTGTATCCTG-3; rev, 5-GACTCCTTTCTCCGCAACAG-3; fwd, 5-GTCACCGTGTCAACCTGATG-3; rev,5-TCCCAGAGCCACCTAAGAGA-3; fwd, 5-GCTCGTCGTCGACAACGGCTC-3; rev, 5-CAAACATGATCTGGGTCATCTTCTC-3. Statistical analysis The significance of the experimental results was determined by the Student’s antitumor activity of MEK and phosphatidylinositol 3-kinase inhibitors in basal-like breast cancer models.
