细胞分裂素参与许多细胞过程,包括胞质分裂和细胞骨架的组织。人Septin-9(SEPT 9)水平的改变与多种癌症有关,而SEPT 9的突变导致发作性神经病,遗传性神经痛性肌萎缩(HNA)。尽管SEPT 9在人类健康中具有重要功能,但其体内作用尚不清楚。在这里,我们利用斑马鱼来研究SEPT 9在早期发育中的作用。我们发现,斑马鱼拥有两个基因,sept 9a和sept 9 b,像人类一样,表达多种转录本。sept 9a转录物的敲低或过表达导致特定的发育改变,包括循环缺陷和异常表皮发育。我们的工作表明,SEPT 9在斑马鱼发育中起着重要作用,并建立了斑马鱼作为一个有价值的模式生物的研究SEPT 9。
Septins are involved in a number of cellular processes including cytokinesis and organization of the cytoskeleton. Alterations in human septin-9 (SEPT9) levels have been linked to multiple cancers, whereas mutations in SEPT9 cause the episodic neuropathy, hereditary neuralgic amyotrophy (HNA). Despite its important function in human health, the in vivo role of SEPT9 is unknown. Here we utilize zebrafish to study the role of SEPT9 in early development. We show that zebrafish possess two genes, sept9a and sept9b that, like humans, express multiple transcripts. Knockdown or overexpression of sept9a transcripts results in specific developmental alterations including circulation defects and aberrant epidermal development. Our work demonstrates that sept9 plays an important role in zebrafish development, and establishes zebrafish as a valuable model organism for the study of SEPT9.
