项目摘要

DESCRIPTION (provided by applicant): Our long-term goal is to develop novel targeted therapy strategies to treat advanced ovarian cancer. In our previous studies of E1A gene therapy for ovarian and breast cancer, we identified PEA15 as being responsible for the antiproliferative effects of E1A on cancer cells. Our subsequent explorations of the molecular mechanism of this phenomenon led us to the central hypothesis of this proposal: that PEA15 has a critical role in ovarian cancer tumorigenicity and treatment response. Supporting evidence for this hypothesis is as follows. First, PEA15 is known to sequester ERK in the cytoplasm, and ERK is known to be involved in cell cycling and enhanced survival of cancer cells. Second, cells in which PEA15 is not phosphorylated at serine 116 undergo apoptosis via tumor-necrosis factor (TNF) signaling, a major apoptosis pathway. Third, overexpression of PEA15 suppresses viability of ovarian cancer cells. Fourth, patients with ovarian cancers that overexpress PEA15 survive longer than those with low-PEA15-expressing tumors. Collectively, these findings implicate PEA15 as a key molecule in ovarian cancer via its ability to block ERK and enhance TNF signaling, and thus could be exploited as a dual-pathway therapeutic gene for patients with ovarian cancer. Our first major goal in this proposal is to delineate the mechanistic and functional significance of PEA15 in ovarian cancer cells. The second major goal is to develop PEA15 as a targeted molecule. To address these two goals, we have developed a comprehensive plan comprising three specific aims: (1) Determine the role of PEA15 in ovarian cancer tumorigenicity; (2) Determine the effects of PEA15 on the sensitivity of ovarian cancer cell to chemotherapy; and (3) Establish how PEA15 modulates erlotinib sensitivity in ovarian cancer cells. This proposal is innovative because PEA15 is thought to target both ERK and TNF signaling pathways, which have been implicated in cancer aggressiveness, induction of apoptosis, and regulation of sensitivity to chemotherapy and EGFR-tyrosine kinase inhibitors. The proposed research is highly relevant to improving outcomes for patients with ovarian cancer because understanding the biology of cancer will lead to the discovery of novel targets to be used in clinical diagnosis and treatment. The ultimate purpose of this project is to build a foundation upon which to design a clinical trial, based on basic research, of PEA15 as a novel target. The proposed research is highly relevant to improving outcomes for patients with ovarian cancer because understanding the biology of cancer will lead to the discovery of novel targets (PEA15 or molecules related to PEA-15) to be used in clinical diagnosis and treatment.
描述(由申请人提供):我们的长期目标是开发新的靶向治疗策略来治疗晚期卵巢癌。在我们以前的E1 A基因治疗卵巢癌和乳腺癌的研究中,我们确定PEA 15负责E1 A对癌细胞的抗增殖作用。我们随后对这一现象的分子机制的探索使我们得出了这一提议的中心假设:PEA 15在卵巢癌致瘤性和治疗反应中起着关键作用。支持这一假设的证据如下。首先,已知PEA 15在细胞质中螯合ERK,并且已知ERK参与细胞周期和增强癌细胞的存活。其次,PEA 15在丝氨酸116处未磷酸化的细胞通过肿瘤坏死因子(TNF)信号传导(一种主要的凋亡途径)经历凋亡。第三,PEA 15的过表达抑制卵巢癌细胞的活力。第四,PEA 15过表达的卵巢癌患者比PEA 15低表达的患者生存时间更长。总的来说,这些发现暗示PEA 15通过其阻断ERK和增强TNF信号传导的能力作为卵巢癌中的关键分子,因此可以被开发为卵巢癌患者的双途径治疗基因。我们的第一个主要目标是描述PEA 15在卵巢癌细胞中的机制和功能意义。第二个主要目标是开发PEA 15作为靶向分子。为了实现这两个目标,我们制定了一个全面的计划,包括三个具体目标:(1)确定PEA 15在卵巢癌致瘤性中的作用;(2)确定PEA 15对卵巢癌细胞对化疗敏感性的影响;(3)确定PEA 15如何调节卵巢癌细胞对厄洛替尼的敏感性。这一提议是创新的,因为PEA 15被认为靶向ERK和TNF信号通路,这两种信号通路与癌症侵袭性、诱导细胞凋亡以及调节对化疗和EGFR-酪氨酸激酶抑制剂的敏感性有关。这项拟议的研究与改善卵巢癌患者的预后高度相关,因为了解癌症的生物学将有助于发现用于临床诊断和治疗的新靶点。该项目的最终目的是建立一个基础,在此基础上设计一个临床试验,基于基础研究,PEA 15作为一个新的目标。这项拟议的研究与改善卵巢癌患者的预后高度相关,因为了解癌症的生物学将导致发现用于临床诊断和治疗的新靶点(PEA-15或PEA-15相关分子)。
