Functional study of LIM-homeodomain proteins Lhx1 and Lhx5 in the maintenance of cerebellar Purkinje neurons in the postnatal and adult mouse.
蒲金氏細胞(Purkinje cell)是小腦中的一種主要神經元,其主要作用在於協調身體活動及平衡。蒲金氏細胞之早期分化需要兩個密切相關的LIM同源盒結構域基因Lhx1及Lhx5。在胚胎小腦發育期間,這兩個基因的失活化會導致蒲金氏細胞數量大量減少。但有趣的是,就算在蒲金氏細胞完成分化之後,Lhx1/5之表達依然維持在高水平。這顯示Lhx1/5在產後小腦發育過程中可能有更多作用。為了研究這些可能作用,我把條件性Lhx1/5雙基因剔除小鼠和Pcp2-IRES-Cre轉基因小鼠交配,從而令Lhx1/5在產後第二天的蒲金氏細胞失活化。結果顯示Lhx1/5雙突變體老鼠在出生後兩星期即有顯著但程度不太大的...
