摘要

通过对MRL/Mp/-lpr/lpr与C3H/HeJ-lpr/lpr两株小鼠进行F50多代选择杂交,建立了一种新的重组基因小鼠菌株McRA1lpr/lpr,表现为严重关节炎,随后出现强直,病理类似于人类类风湿关节炎。为了阐明该菌株关节炎发生的遗传机制,我们基于Shiro MORI收集整理的700多只McRA1-lpr/lpr小鼠的数据,新制备了“GTree”,对关节炎、脾肿大和淋巴结病的病理表型进行谱系分析。数据本身现在由Hideki SAWADA管理的PostgreSQL Linux服务器处理。我们解释了程序的算法及其复杂性,并展示了仅在RA小鼠组中出现的脾脏和腋窝淋巴结的病理特性。

Complexity and application of pedigree analysis programme GTree
A novel recombinant congenic mouse strain, McRA1lpr/lpr, which was established by the intercrosses between MRL/Mp/-lpr/lpr and C3H/HeJ-lpr/lpr strains throughout more than F50 generations by means of selection based on swelling of ankle joints, manifested severe arthritis, followed by ankylosis, pathologically resembling rheumatoid arthritis in humans. To clarify the genetic mechanisms on the development of arthritis in this strain, we newly prepared "GTree" for analyzing the pedigree of pathological phenotypes of arthritis, splenomegaly and lymphadenopathy based on the collected data from over 700 McRA1-lpr/lpr mice collected and arranged by Shiro MORI. The data themselves are now dealt with by a PostgreSQL Linux server administered by Hideki SAWADA. We explain the algorithm of the program and its complexity, and show the pathological peculiarity of spleens and axillary lymph nodes which appear only in the group of RA mice.
