PROJECT SUMMARY/ABSTRACT There is growing evidence for the role of stress in cardiovascular pathologies, cancer, and other diseases. Work from our group and others has shown that psychological states such as chronic stress or depression may accelerate growth of existing tumors and promote chemoresistance. Importantly, a significant number of ovarian cancer patients are clinically depressed or lack social support. These emotional states have been linked to sustained activation of the sympathetic nervous system and decreased survival. Our group has shown that activation of the sympathetic nervous system leads to increased levels of norepinephrine and epinephrine in the tumor microenvironment and ovarian cancer progression by inducing pro-tumoral pathways. Our preliminary data in cancer cell lines suggest that norepinephrine significantly changes the expression of genes implicated in ovarian cancer and attenuates cisplatin-induced ovarian cancer cell apoptosis. Given the importance of BRCA1-regulated DNA repair mechanisms in cisplatin response, adrenergic regulation of BRCA1 expression in tumors may also impact ovarian cancer progression and resistance to platinum-based therapy. However, the underlying mechanisms behind these observations are not completely understood. In this pilot we will test this hypothesis by achieving the following aims: 1) To dissect the effects of adrenergic signaling in ovarian cancer cells and 2) To explore the association between perceived stress and depressive symptomatology with tumor catecholamines, DNA damage, and BRCA1 protein expression. This proposal provides a unique approach to explore the link between stress and ovarian cancer outcomes at both the tumor level and the patient level. This proposal will provide the groundwork for additional research on precision medicine by linking psychological risk factors with underlying tumor biology.

项目摘要/摘要 越来越多的证据证明了压力在心血管病理，癌症和其他疾病中的作用。 我们小组和其他人的工作表明，诸如慢性压力或抑郁之类的心理状态可能 加速现有肿瘤的生长并促进化学抗性。重要的是，大量 卵巢癌患者在临床上沮丧或缺乏社会支持。这些情绪状态已经 与交感神经系统的持续激活和生存降低有关。我们的小组有 表明交感神经系统的激活导致去甲肾上腺素的水平增加 肿瘤微环境和卵巢癌进展中的肾上腺素通过诱导促肿瘤途径。 我们在癌细胞系中的初步数据表明，去甲肾上腺素显着改变了 与卵巢癌有关的基因并减弱了顺铂诱导的卵巢癌细胞凋亡。鉴于 BRCA1调节的DNA修复机制在顺铂反应中的重要性，肾上腺素能调节 肿瘤中的BRCA1表达也可能影响卵巢癌的进展和对基于铂的抗性 治疗。但是，这些观察结果背后的基本机制尚未完全理解。在 该飞行员将通过实现以下目的来检验这一假设：1）剖析肾上腺素能的影响 卵巢癌细胞中的信号传导和2）探索感知应力与抑郁症之间的关联 肿瘤儿茶酚胺，DNA损伤和BRCA1蛋白表达的症状学。这个建议 提供了一种独特的方法来探索两种肿瘤的压力与卵巢癌结果之间的联系 水平和患者水平。该建议将为精确研究提供基础 通过将心理危险因素与潜在的肿瘤生物学联系起来的医学。
