紫杉醇可使微管蛋白和组成微管的微管蛋白二聚体失去动态平衡,诱导与促进微管蛋白聚合、微管装配、防止解聚,从而使微管稳定并抑制癌细胞的有丝分裂和防止诱导细胞凋亡,进而有效阻止癌细胞的增殖,起到抗癌作用。


使用本产品的应用案例(仅供参考

In Vitro:

细胞实验:Cytotoxicity determination: The IC50 of cells exposed to PTX was determined using a Cell Counting Kit (CCK)‑8 assay. In brief, cells were inoculated at a concentration of 4x103/100 µl per well and cultured at 37˚C for 12 h in a 96‑well plate. The cells were then maintained at 37˚C with 200 µl fresh medium containing different concentrations of PTX (0‑50 nM) for 48 h. Following this, the cells were incubated with 20 µl CCK‑8 solution at 37˚C for 24 h. Then, the optical density value of each well was detected using a microplate reader at 450 nm.

ROS检测:For ROS detection, 5x105 cells were seeded overnight in a 6‑well plate and then treated with PTX (5 nM) at 37˚C for 48 h. Subsequently, 5 µM carboxy 2'‑7'‑dichlorofluorescein diacetate was added in Hanks' Balanced Salt Solution and incubated with cells at room temperature for 0.5 h. Fresh tissues were harvested, followed by a single cell suspension preparation. Tissue was digested with trypsin to obtain single cell suspension. Cells were then inoculated in a 6‑well plate as aforementioned. The levels of intracellular peroxide were measured using a flow cytometer at 485 nm excitation and 520 nm emission to analyze the ROS generation.

In Vivo:

小鼠,腹腔注射:Xenograft and grouping:In total, 16 male nude mice (age, 6‑8 weeks; weight, 25‑30 g) . Mice were housed  at 25±1˚C with 12‑h light/dark cycles, 50±5% humidity and  free access to food and water. The mice were randomly divided into four groups: i) CD44+CD117++ PTX (Beijing Solarbio Science & Technology Co., Ltd.) group (n=4); ii) CD44+CD117++ PTX + CCL20 (Beijing Solarbio Science & Technology Co., Ltd.) group (n=4); iii) CD44CD117+ PTX group (n=4); and iv) CD44CD117 + PTX + CCL20 group (n=4). For xenografts, CD44+CD117+(2x106) subsets or CD44CD117subsets cells (2x106) suspended in 0.5 ml PBS were subcutaneously injected into the left flank of each nude mouse to establish tumors. Then, PTX (10 mg/kg) and/or CCL20 (1 mg/kg) were injected intraperitoneally simultaneously on days 1, 3 and 7. Tumor size was monitored on the 3rd, 7th, 14th, 21st and 28th days (15). At the end of the experiment and under continuous anesthesia, the animals were euthanized by an overdose of pentobarbital (125 mg/kg).
