Impact of SRCIN1/p140Cap gene alteration in ERBB2/HER2-amplified breast cancer and neuroblastoma. Amplification of the SRCIN1 gene in ERBB2/HER-2-positive breast cancer patients impairs tumor growth and metastasis mainly through the down-regulation of Tiam1/Rac1 axis. SRCIN1 aberrant alterations such as translocations, deletions or loss of heterozygosity promote tumor growth, metastasis and drug resistance in NB patients, consistent with the loss of p140Cap expression, and inhibition of both Src and STAT3/Jak2 pathways
