Gypenoside LI   中文名称: 绞股蓝皂苷LI

A549 细胞受到绞股蓝皂苷 LI (0-80 μM) 的剂量依赖性抑制。在 A549 细胞中，绞股蓝皂苷 LI 诱导 G2/M 期并阻止细胞凋亡[1]。绞股蓝皂苷 LI 可以提高细胞内的 ROS 水平。 A549 细胞迁移被绞股蓝皂苷 LI 抑制[1]。很明显，绞股蓝皂苷 LI 可以抑制 CDK1 蛋白表达，而不是 CDK2 和 CDK4 蛋白表达[1]。在黑色素瘤细胞中，绞股蓝皂苷 LI 上调 miR-128-3p 的表达并抑制细胞增殖[2]。绞股蓝皂苷 LI（75 和 29.71 μg/mL）除了引起内在细胞凋亡外，还可引起 S 期阻滞。绞股蓝皂苷 LI 通过阻断 Wnt/β-catenin 信号通路来阻碍黑色素瘤形成集落的能力 [2]。在 A375 和 SK-MEL-28 黑色素瘤细胞中，绞股蓝皂苷 LI 会引起 PARP 裂解，上调裂解的 caspase-9 和 BID 死亡激动剂的表达，并下调 FLIP（长形式）和 BCl-2 的表达[2]。

Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)
*Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline)
Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil)
Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
