项目摘要

DESCRIPTION (provided by applicant): Non-Hodgkin's lymphoma accounts for approximately 50,000 new cases of cancer annually. This figure represents an increase beyond that seen for most other forms of cancer. Among the non-Hodgkin's lymphomas, follicular lymphoma represents the most common subtype of low-grade B-cell lymphoma in adults, and typically pursues an indolent clinical course. In a significant proportion of cases there is histologic transformation from a low-grade neoplasm to an aggressive diffuse large B-cell lymphoma with significantly decreased median survival. The recent advent of sophisticated mass spectrometry technology coupled with software algorithms that permit instantaneous protein identification, makes it feasible to study the pattern of protein deregulation that distinguish two biologic states. We propose to employ a combination of chromatographic techniques and tandem mass spectrometry in the identification of the alterations in protein expression that accompany histologic transformation. We shall be analyzing a cohort of matched pairs of follicular lymphoma and their transformed diffuse large B-cell lymphoma counterparts occurring in the same individual. Relevance: Comprehensive identification of the qualitative and quantitative changes in protein expression that are involved in follicular lymphoma transformation will permit the delineation of deregulated pathways, identify distinct prognostic subgroups of transformed lymphoma, and facilitate the development of novel therapies that target susceptible elements in the deregulated pathways.

描述（由申请人提供）：非霍奇金的淋巴瘤每年约为50,000例新的癌症病例。这个数字代表了大多数其他形式的癌症的增加。在非霍奇金的淋巴瘤中，卵泡淋巴瘤代表了成人低度B细胞淋巴瘤最常见的亚型，并且通常追求懒惰的临床过程。在很大一部分的情况下，组织学从低级肿瘤转变为侵袭性弥漫性大B细胞淋巴瘤，中位存活率显着降低。复杂的质谱技术的最新出现以及允许瞬时蛋白质识别的软件算法，使研究蛋白质不足管制的模式可行，从而区分两个生物学状态。我们建议在鉴定组织学转化的蛋白质表达变化中采用色谱技术和串联质谱。我们将分析一对匹配的卵泡淋巴瘤及其转化的大型B细胞淋巴瘤的转化，发生在同一个体中。相关性：卵泡淋巴瘤转化所涉及的蛋白质表达的定性和定量变化的全面鉴定将允许描绘消失受管化的途径，确定转化的淋巴瘤的独特预后亚组，并促进针对消失路径中敏感元素的新颖疗法的发展。
