此前,带有Wild-type KRAS而不依赖KRAS突变的自发胰腺癌小鼠模型极为匮乏。 本研究中,研究人员首先构建转基因小鼠模型,发现小鼠携带SMAD4缺失或者TGFBR2缺失,再联合p53缺失时,能够在Wild-type KRAS背景下诱导形成自发胰腺癌。 接下来,研究人员...

首页 / 癌基因 / KRAS / WILD TYPEKRAS(KRAS proto-oncogene, GTPase) KRAS (Kirsten Rat Sarcoma Viral Oncogene Homolog)基因是GDP/GTP结合蛋白,比较重要的同家族基因还包括HRAS和NRAS。KRAS与GTP结合呈激活状态,与GDP结合呈关闭状态,KRAS可被生长因子或酪氨酸激酶(如EGFR)短暂活化,活化后的KRAS可以激活下游如...
图三 全体患者(左)和PFS≤3个月的患者中KEAP1、SMARCA4 和 CDKN2A共突变的比例,图示Wild-type指野生型,Mut指突变型,only指单一共突变STK11也是早期进展患者中常见的共突变,不过详细分析发现,只有当KEAP1和STK11同时突变才与PFS和OS缩短显著相关。TP53也是常见共突变,不过其与疗效无关。图四 KEAP1野生型...
点击Create Group From Selected Diagram Areas,将这组数据命名为KRAS Wildtype。 点击Submit,之后在圆圈上册的一栏中选择KRAS Wildtype和KRAS Mutant,如下。 能看到两组的病人sample没有overlap。 因为我们这次要分析KRAS突变和没突变的两组基因表达差异,所以我们进入mRNA的页面。 在mRNA expression一栏中,μ代表mean ...
Wild-type KRAS (KRASWT) amplification has been shown to be a secondary means of KRAS activation in cancer and associated with poor survival. Nevertheless, the precise role of KRASWT overexpression in lung cancer progression is largely unexplored. Here, w

We demonstrate that FASN, the rate-limiting enzyme in FA synthesis, while being dispensable in EGFR-mutant or wild-type KRAS LC, is required for the viability of KMLC cells. Integrating lipidomic, transcriptomic and functional analyses, we demonstrate that FASN provides saturated and monounsaturated...
