| 产品描述: | Vacuolin-1 是一种有效的细胞渗透性抑制剂,可阻断 Ca(2+)-dependent exocytosis of lysosomes,并防止溶酶体内容的释放而不会影响重新封装的过程。Vacuolin-1 还是一种有效的、具有选择性的 PIKfyve 的抑制剂,通过抑制PIKfyve的溶酶体成熟来抑制自噬 |
| 靶点: |
PIKfyve;PI3K; Autophagy |
| 体外研究: |
Vacuolin-1 blocks both ionophore- and wound-induced, Ca2+-dependent exocytosis of lysosomes, but does not block Ca2+-dependent fusion of enlargeosomes with the plasma membrane |
| 体内研究: |
Vacuolin-1 significantly suppresses the metastasis and/or tumor growth of breast cancer or melanoma. Vacuolin-1 targets Capping protein Zβ (CapZβ) to inhibit endosomal trafficking and metastasis |
| 细胞实验: |
Cell lines: Human HeLa cells, Human A431 cells, monkey BSC-1 cells Concentrations: 1 μM-10 μM Incubation Time: 20-180 min Method: HeLa cells grown on 25 mm diameter coverslips in six-well plates are incubated for 10 min with BSA conjugated with 5 nm gold particles, followed by a 3–12 h incubation in a medium without BSA–gold. During the last 20–180 min of the chase, the cells are incubated in 0.2% DMSO with or without 1 μM vacuolin-1. For electron microscopy, cells are washed with PBS, fixed at room temperature for 30 min, and processed for ultrathin cryosectioning and immunolabelling. |
