Rab5 is a GTPase protein that is involved in intracellular membrane trafficking. It functions by binding to various effector proteins and regulating cellular responses, including the formation of transport vesicles and their fusion with the cellular membrane. Rab5 has been reported to play an important role in the development of the zebrafish embryo;however, its role in axonal regeneration in the central nervous system remains unclear. In this study, we established a zebrafish Mauthner cell model of axonal injury using single-cell electroporation and two-photon axotomy techniques. We found that overexpression of Rab5 in single Mauthner cells promoted marked axonal regeneration and increased the number of intra-axonal transport vesicles. In contrast, treatment of zebrafish larvae with the Rab kinase inhibitor CID-1067700markedly inhibited axonal regeneration in Mauthner cells. We also found that Rab5 activated phosphatidylinositol 3-kinase(PI3K) during axonal repair of Mauthner cells and promoted the recovery of zebrafish locomotor function. Additionally, rapamycin, an inhibitor of the mechanistic target of rapamycin downstream of PI3K, markedly hindered axonal regeneration. These findings suggest that Rab5 promotes the axonal regeneration of injured zebrafish Mauthner cells by activating the PI3K signaling pathway.

针对复杂地质构造区遗留资源开发过程中巷道掘进安全性问题,为研究遗留煤柱及断层构造对巷道掘进的影响,以运河煤矿充填工作面巷道掘进为工程背景,综合运用现场调研、数值建模分析等手段,对遗留煤柱及断层影响下巷道掘进过程中应力变化规律进行了研究。结果表明,当巷道迎头距离断层40 m时,断层附近的集中应力开始迅速升高,巷道迎头距离采空区边界30 m时,掘进迎头集中应力开始升高;过采空区边界30 m后,集中应力降至正常水平以下。研究结果为类似地质条件的巷道掘进及针对性支护设计提供了依据。
