项目摘要
DESCRIPTION (provided by applicant): Lung cancer is the leading cause of cancer-related death in the United States in both men and women. In 2006, more than 174,470 new cases of lung cancer are estimated in the United States alone, and 162,460 of lung cancer-related death. The data reflect our lack of ability to improve survival and quality of life of the patients under current treatment strategies. Targeted therapy, a newly emerged therapeutic approach aiming key molecular abnormalities in cancer progression, has shown encouraging results, such as the development of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors and vascular endothelial growth factor (VEGF) inhibitors for patients with lung cancer. We recently discovered that hepatoma-derived growth factor (HDGF), a mitogen for both stroma cells and epithelial cells, is frequently overexpression in non-small cell lung cancer (NSCLC), which accounts for >80% of all lung cancers, and the overexpression is strongly correlated with tumor relapse and poor survivals. We further demonstrated that HDGF is involved in malignant transformation, tumor progression, and invasion. We have developed a panel of neutralizing monoclonal antibodies against HDGF. Our preliminary data show that the antibodies are effective in inhibiting lung cancer growth in xenograft tumor models, suggesting HDGF is a novel therapeutic target. We hypothesize that HDGF is a critical factor in progression of NSCLC and a novel therapeutic target. To test the hypothesis, we proposed three specific aims in this application: In Aim 1, we will determine the role of HDGF as a prognostic marker for patients with NSCLC by analyzing expression of HDGF in primary NSCLC and correlating the expression with clinicopathologic parameters. The correlation between HDHF expression and other angiogenic factors and potential HDGF downstream molecules will also be determined. In Aim 2, we will determine the therapeutic role of HDGF neutralizing monoclonal antibodies in NSCLC xenograft models and to reveal potential mechanisms of the anti-tumor effects. We will emphasize the use of the antibodies as a single agent with limited combination to prove of principles. In Aim 3, we will verify the therapeutic effects of the HDGF neutralizing antibody based regimens in heterotransplant tumor models and to identify selective and/or predictive biomarkers for anti-HDGF based therapy. The success of the project will provide strong rationale and scientific knowledge to guide development of anti-HDGF therapy for patients with lung cancer. PUBLIC HEALTH RELEVANCE: Hepatoma-derived growth factor (HDGF) is a novel molecule important for lung cancer progression. This study will evaluate the role of HDGF as a prognostic marker for identifying lung cancer patients likely to recur or metastasize after curative surgical treatment. We will also evaluate our newly developed neutralizing monoclonal anti-HDGF antibodies for their utility as therapeutic agents in lung cancer treatment.
描述(由申请人提供):肺癌是美国男性和女性与癌症相关死亡的主要原因。 2006年,仅在美国,就估计有174,470例新的肺癌病例,其中162,460例与肺癌相关的死亡。数据反映了我们缺乏在当前治疗策略下改善患者生存和生活质量的能力。靶向疗法是一种新出现的治疗方法,旨在癌症进展中关键分子异常的治疗方法,它表现出令人鼓舞的结果,例如表皮生长因子受体(EGFR)酪氨酸激酶抑制剂和血管内皮生长因子(VEGGF)抑制剂抑制肺癌患者。我们最近发现,在非小细胞肺癌(NSCLC)中,肝癌衍生的生长因子(HDGF)经常过表达,占所有肺癌的80%以上,并且过表达与肿瘤复发和贫困生存力密切相关。我们进一步证明了HDGF参与恶性转化,肿瘤进展和侵袭。我们已经开发了一个针对HDGF中和单克隆抗体的小组。我们的初步数据表明,抗体在异种移植肿瘤模型中有效抑制肺癌的生长,这表明HDGF是一种新型的治疗靶标。我们假设HDGF是NSCLC进展和新型治疗靶标的关键因素。为了检验该假设,我们在此应用中提出了三个特定目的:在AIM 1中,我们将通过分析HDGF在初级NSCLC中的表达来确定HDGF作为NSCLC患者的预后标记的作用,并将表达与临床病理学参数相关。还将确定HDHF表达与其他血管生成因子与潜在的HDGF下游分子之间的相关性。在AIM 2中,我们将确定HDGF中和NSCLC异种移植模型中中和单克隆抗体的治疗作用,并揭示抗肿瘤作用的潜在机制。我们将强调将抗体用作具有有限组合的单一药物来证明原理。在AIM 3中,我们将验证HDGF中和基于抗体模型中和基于抗体模型的抗体方案的治疗作用,并确定基于抗HDGF的治疗的选择性和/或预测性生物标志物。该项目的成功将为肺癌患者提供强大的理由和科学知识,以指导抗HDGF疗法的开发。公共卫生相关性:肝癌衍生的生长因子(HDGF)是一种对肺癌进展至关重要的新分子。这项研究将评估HDGF作为预后标志物在治愈手术治疗后可能会复发或转移的肺癌患者的作用。我们还将评估我们新开发的中和单克隆抗HDGF抗体,以作为其作为肺癌治疗中治疗剂的效用。
