中心粒/中心體，纖毛，神經幹細胞，與癌細胞分裂之研究

細胞中心體含有母、子二顆中心粒，主要是促成細胞纖毛，鞭毛的形成及參與細胞有絲分裂。畸型小頭症（MCPH）是一種人類遺傳疾病，主要症狀是病人腦容量小，並伴隨中，重度智力障礙。目前已知多個MCPH基因缺陷會造成畸型小頭症。近年來本研究室解開其中4個畸型小頭症蛋白CPAP, STIL, CEP135, 和RTTN的功能。本研究室發現STIL（EMBO J, 2011)， CEP135 (EMBO J, 2013) 都會與CPAP蛋白（Nat Cell Biol 2009）結合，且RTTN亦會與STIL結合（Nat Commun 2017, Cells 2021），形成多個蛋白質複合體，共同參與中心粒的複製與細胞分裂。有趣的是CPAP蛋白缺失會誘發神經幹細胞死亡，神經細胞過早分化，及嚴重腦部病變 （J Cell Sci 2020）。據此我們提出一個假設：干擾細胞中心粒複製，將會抑制神經幹細胞分裂與減少大腦皮層神經細胞數目，繼而造成人類畸型小頭症。另外本研究室亦發現CEP120 (J Cell Biol, 2013; Sci Rep, 2019)與CEP295 (J Cell Sci 2016)蛋白會調控中心粒長度，且Myosin-Va在纖毛起始過程中扮演一非常重要的角色：Myosin-Va會將preciliary vesicles首先帶到母中心粒上，繼而開啟了纖毛形成初始機轉(Nat Cell Biol 2018)。近年來癌細胞發現有基因體不穩定現象，此有可能是中心體複製不正常所致。未來本研究室將利用分子，細胞，遺傳，小鼠模式，及hiPSC-derived類人腦器官之技術來探討中心體/中心粒及纖毛形成機轉，並探討干擾此機轉所可能誘發人類畸型小頭症，纖毛病變，及癌基因體不穩定之病因。
