项目摘要

DESCRIPTION (provided by applicant): Tumor metastasis is the major cause of death in cancer patients. Thus, blocking tumor metastasis will significantly increase the survival rate of cancer patients and allow more moderate radiation or chemotherapy with less side-effects. One critical step of tumor metastasis is tumor cell migration and invasion. In this application, we focus on fascin, an actin-bundling protein, which is critical for tumor invasion and metastasis. Elevated expression of fascin is correlated with poor prognosis and short survival in cancer patients. In specific aim 1, we will investigate the mechanism of action of fascin inhibitors. In specific aim 2, we will further optimize fascin inhibitors. In specific aim 3, we will use animal models to examine the efficacy and toxicity of optimized fascin inhibitors.

描述（申请人提供）：肿瘤转移是癌症患者死亡的主要原因。因此，阻断肿瘤转移将显着提高癌症患者的生存率，并允许更温和、副作用更少的放疗或化疗。肿瘤转移的关键步骤之一是肿瘤细胞的迁移和侵袭。在此应用中，我们重点关注肌成束蛋白，一种肌动蛋白捆绑蛋白，对肿瘤侵袭和转移至关重要。肌成束蛋白表达升高与癌症患者的不良预后和短生存期相关。在具体目标1中，我们将研究肌成束蛋白抑制剂的作用机制。在具体目标2中，我们将进一步优化肌成束蛋白抑制剂。在具体目标3中，我们将使用动物模型来检查优化的肌成束蛋白抑制剂的功效和毒性。
