My summer life in Yang-Ming 微生物及免疫學研究所 張南驥老師 神經科學研究所 錢嘉韻老師 生科04級 891632 曾煥昌
實驗室簡介 張南驥老師 1.巨噬細胞分泌性蛋白 (YM-1). 2.神經元 LUZP 蛋白. 錢嘉韻老師 1.α2 腎上腺素受體位置及功能研究. 2.建立 TG & KO mice 來做基因標的.
My project • KO 老鼠的建立 • Lupz 基因的研究 • 老鼠的行為
KO老鼠 • nn promoter • rtTA and TRE system • Cre/loxP system
nn promoter • nn: the promoter of α2C4 , one kind of the recepter of epinephrine.
Cre/loxP system • Cre/loxP is the recombinase system of bacteriophage p1. • Cre recognizes and catalyzes recombination between 34bps loxP site.
Combine all nn rtTA Cre TRE nn : tissue-specific rtTA & TRE : doxycycline induce Cre/loxP : turn on knock-out
How to apply on mice? • Do microinjection on the mice, get transgenic mice(chimeric mice). • Mate the mice to get hetozygotes. • Mate hetrozygotes to get homozygotes.
What is the advantage? The target gene may be lethal. The knock out mice can be survival until we turn on the system.

Luzp • Luzp encodes a protein (LUZP) expressingin brain areas such as hippocampus and cerebellum . • Subcellular localization is also revealed by immunocytochemistry(ICC) .
+/+ +/- +/- -/- +/- -/- +/- +/+ -/- +/- +/+ +/- -/- +/+ What’s wrong with Luzp KO mice? - Neural tube closure defect
E10.5 E11.5 E14.5 Exencephaly in Luzp-/- mice through E10.5 to E14.5
What did I do in summer? • Southern blot • Vector construct • PCR • ICC • Feed mice and clean their room ^^|||
