ERBB2 (v-erb-b2 avian erythroblastic leukemia viral oncogene homolog 2) amplification is associated with invasive breast cancer. We discovered that TOM1L1 (target of myb1-like 1) and ERBB2 co-amplification defines a novel mechanism involved in breast cancer metastatic progression. Upregulation of the vesicular trafficking protein TOM1L1 enhances plasma membrane delivery of membrane-type 1 matrix metalloprotease (MT1-MMP) for efficient extracellular matrix degradation and tumor cell dissemination.
ERBB2(v-erb-b2禽成红细胞白血病病毒癌基因同源物2)扩增与浸润性乳腺癌相关。我们发现TOM1L1(类Myb1靶点1)与ERBB2共同扩增定义了一种参与乳腺癌转移进展的新机制。囊泡运输蛋白TOM1L1的上调增强了膜型1基质金属蛋白酶(MT1-MMP)向质膜的转运,从而有效地降解细胞外基质并促进肿瘤细胞播散。
