| 产品描述: | Hedgehog 抑制剂;Hedgehog inhibitor;;InformationCiliobrevin D (compound 5) is a cell-permeable, reversible and specific antagonist of AAA+ (ATPases associated with diverse cellular activities) ATPase motorcytoplasmic dynein. Ciliobrevin D perturbs primary cilia formation and blocksHedgehog (Hh)signaling.Targetscytoplasmic dynein ; HedgehogIn vitroCiliobrevin D inactivate dynein in Sertoli cells. The inactivation of dynein by ciliobrevin D also perturbs gross disruption of F-actin across the Sertoli cells in vitro. Ciliobrevin D perturbs protein trafficking within the primary cilium, leading to their malformation and Hedgehog signaling blockade. Ciliobrevin D also prevents spindle pole focusing, kinetochore-microtubule attachment, melanosome aggregation, and peroxisome motility in cultured cells.In vivoCiliobrevin D inactivate dynein in the testis. The inactivation of dynein by ciliobrevin D also perturbs gross disruption of F-actin across the seminiferous epithelium illustrating there are cross talks between the two cytoskeletons in the testis.Cell Research(from reference)Cell lines:Sertoli cells Concentrations:15 µM, 30 µM Incubation Time:1 h |

| 体内研究: |
体内睾丸中 Dync1h1 的敲低或动力蛋白 1 的灭活会扰乱精子发生。 Dync1h1 的敲低或使用 Ciliobrevin D 使睾丸中的动力蛋白 1 失活,会通过改变 EB1 的空间表达来扰乱 MT 组织,扰乱 F-肌动蛋白组织,并扰乱 BTB 上粘附蛋白复合物的分布,从而导致 BTB 完整性丧失。 Dync1h1 敲除或动力蛋白 1 被 Ciliobrevin D 灭活后,生精上皮中的 F-肌动蛋白解体是由肌动蛋白调节蛋白 Arp3 和 Eps8 的时空表达变化介导的。 |
