DNA array hybridization technology will be used to create a database of quantitative gene expression changes in aging cells and tissues. During the Phase I study, methods for high throughput gene expression analysis using Nylon based DNA arrays will be developed and validated, the feasibility of constructing probes from laser capture microdissected tissues will be established, and the feasibility of using this data to detect differences in age-related gene expression will be demonstrated. LifeSpan will then market access to this database to the academic and pharmaceutical communities as a resource for information on gene expression and aging. The discovery of genes that are differentially expressed in aging will ultimately provide information that will be used in the design of agents for therapeutic intervention in age-related degeneration and disease. PROPOSED COMMERCIAL APPLICATIONS: The resulting database of gene expression will be marketed directly to the academic and industrial scientific community as a commercial database product. In addition, the identification of disease-associated aging genes will result in opportunities for the development of diagnostics and therapeutics to treat aging related diseases.

DNA阵列杂交技术将用于创建衰老细胞和组织中定量基因表达变化的数据库。在I期研究期间，将开发和验证使用基于尼龙的DNA阵列进行高通量基因表达分析的方法，将建立从激光捕获显微切割组织构建探针的可行性，并将证明使用该数据检测年龄相关基因表达差异的可行性。然后，LifeSpan将向学术界和制药界出售该数据库，作为基因表达和衰老信息的资源。在衰老过程中差异表达基因的发现将最终提供用于设计年龄相关变性和疾病的治疗干预剂的信息。拟议的商业应用：由此产生的基因表达数据库将作为商业数据库产品直接销售给学术界和工业科学界。此外，与疾病相关的衰老基因的鉴定将为开发治疗衰老相关疾病的诊断和治疗方法带来机会。
