Oral-Facial-Digital type I (OFD1) is a rare inherited form of renal cystic disease associated with ciliary dysfunction. This disorder is due to mutations in the OFD1 gene that encodes a protein localized to centrosomes and basal bodies in different cell types. Immunofluorescence analysis demonstrated that OFD1 displays a dynamic distribution during cell cycle. High-content microscopy analysis of Ofd1-depleted fibroblasts revealed impaired cell cycle progression. Immunofluorescence analysis and cell proliferation assays also indicated the presence of a variety of defects such as centrosome accumulation, nuclear abnormalities and aneuploidy. In addition, Ofd1-depleted cells displayed an abnormal microtubule network that may underlie these defects. All together our results suggest that OFD1 contributes to the function of the microtubule organizing center (MTOC) in the cell, controlling cell cycle progression both in vitro and in vivo.
口腔面指(趾)综合征 1 型(OFD1)是一种罕见的遗传性肾囊性病,与纤毛功能障碍有关。该疾病是由于 OFD1 基因突变所致,该基因编码一种定位于中心体和基底体的蛋白,存在于不同类型的细胞中。免疫荧光分析表明,OFD1 在细胞周期中呈现动态分布。对 Ofd1 缺陷成纤维细胞进行高内涵显微镜分析显示,细胞周期进程受损。免疫荧光分析和细胞增殖实验也表明存在多种缺陷,如中心体积累、核异常和非整倍体。此外,OFD1 缺陷细胞显示出异常的微管网络,这可能是这些缺陷的基础。总之,我们的研究结果表明,OFD1 有助于细胞中微管组织中心(MTOC)的功能,控制体外和体内的细胞周期进程。
