项目摘要

A. STATEMENT OF OBJECTIVES The Cell Biology Core is a new facility and will serve all four projects. This core will provide several lipoprotein-producing and non-lipoprotein producing cell lines required for studies described in each project. The lipoprotein producing cells will be used: 1) To study the mechanisms of assembly and secretion of endogenous apoA-l- and apoB-containing nascent lipoprotein particles; 2) To determine the effects of several apoA-l mimetic peptides on the concentration, composition, and properties of apoA-l- and apoB-containing nascent lipoprotein particles; 3) For transfection studies to assess the structure-function relationship of apoB, and potentially apoA-l, and their respective particle assembly and secretion; 4) To silence the gene of interest using miRNA technique; 5) To establish clonal stable transformants of cells that express C-terminally truncated forms of human apoB or cells that lack specific gene, i.e, lipid transfer proteins. The non-lipoprotein producing cell lines will be used: 1) For the expression of ABCA1, ABCG1, and ABCG4; 2) To established clonal statble cell lines overexpressing ABCA1, ABCG1, and ABCG4; 3) To evaluate the effects of apoA-l mimetic peptides on LPS-induced adhesion of THP-1 monocytes to HUVECs; 4) For cholesterol efflux studies.

A.目标声明细胞生物学核心是一个新设施，将为所有四个项目提供服务。这个核心将提供研究所需的几种脂蛋白产生和非脂蛋白产生细胞系在每个项目中描述。将使用脂蛋白产生细胞的脂蛋白：1）研究组装机制和内源性ApoA-L-和含Apob的新生脂蛋白颗粒的分泌； 2）到确定几种apoA-l模拟肽对浓度，组成和含有ApoA-L-和含Apob的新生脂蛋白颗粒的特性； 3）转染评估APOB和APOA-L的结构功能关系的研究各自的粒子组装和分泌； 4）使用miRNA沉默感兴趣的基因技术; 5）建立表达C末端的细胞的克隆稳定转化体缺乏特定基因的人类APOB的截断形式，即脂质转移蛋白。将使用非脂蛋白产生细胞系：1）用于ABCA1的表达， ABCG1和ABCG4; 2）建立过表达ABCA1的克隆大细胞系， ABCG1和ABCG4; 3）评估ApoA-L模拟肽对LPS诱导的影响 THP-1单核细胞对HUVEC的粘附； 4）用于胆固醇外排研究。
