在小鼠中,Lkb 1缺失和KrasG 12 D的激活导致肺肿瘤具有高淋巴结转移率和远处转移。我们分析了这些原发性和转移性原发性肺癌与整合的基因组和蛋白质组学谱,并确定了与Lkb 1丢失和进展为侵袭性和转移性肺肿瘤相关的基因和磷蛋白特征。这些研究表明,SRC在Lkb 1缺陷的原发性和转移性肺肿瘤中被激活,并且SRC、PI 3 K和MEK 1/2的组合抑制导致协同的肿瘤消退。这些研究表明,整合的基因组和蛋白质组学分析可用于识别可能靶向治疗的信号通路。
In mice, Lkb1 deletion and activation of KrasG12D results in lung tumors with a high penetrance of lymph node and distant metastases. We analyzed these primary and metastatic de novo lung cancers with integrated genomic and proteomic profiles and have identified gene and phosphoprotein signatures associated with Lkb1 loss and progression to invasive and metastatic lung tumors. These studies revealed that SRC is activated in Lkb1 deficient primary and metastatic lung tumors and that the combined inhibition of SRC, PI3K and MEK1/2 resulted in synergistic tumor regression. These studies demonstrate that integrated genomic and proteomic analyses can be used to identify signaling pathways that may be targeted for treatment.
