产品描述 Description

Epibrassinolide is a ubiquitously occurring brassinosteroid plant growth hormone^[1]. Epibrassinolide is widely used as a plant growth regulator to alleviate heavy-metal and pesticide stress^[2]. Epibrassinolide is also used as a potential apoptotic inducer in various cancer cells^[3].

In vitro, treatment of LNCaP and DU145 prostate cancer cells with Epibrassinolide (25μM; 24h) induced mitochondria-mediated apoptosis, significantly decreased cell viability, increased sub-G1 DNA fragmentation, activated caspase cascades, and depleted intracellular polyamine levels^[4]. Treatment of SW480 and DLD-1 colon cancer cells with Epibrassinolide (25μM; 48h) induced autophagy, depleted intracellular polyamines, activated Akt/mTOR signaling, and significantly increased LC3 lipidation and SSAT/PAO expression^[5].

In vivo, Epibrassinolide (0–720μg/kg/day; 40 days; i.p.) reduced tumor volume and diameter, and decreased the CEA level in the serum in SW480-derived xenografts in SCID mice^[6]. Epibrassinolide (1μM; 24h; aqueous exposure at 5mL/well) reversed ethanol-induced behavioral deficits and restored GSH/GSSG redox balance in zebrafish embryos^[7].

Epibrassinolide是一种广泛存在的油菜素类固醇植物生长激素^[1]。Epibrassinolide广泛用作植物生长调节剂来缓解重金属与农药胁迫^[2]。Epibrassinolide也被用作多种癌细胞的潜在凋亡诱导剂^[3]。

体外实验中，对LNCaP和DU145前列腺癌细胞用Epibrassinolide（25μM；24小时）处理诱导了线粒体介导的凋亡，显著降低了细胞活性，增加了亚 G1 期 DNA 片段化，激活了级联的半胱天冬酶，并减少了细胞内多胺水平^[4]。对SW480和DLD-1结肠癌细胞用Epibrassinolide（25μM；48小时）处理诱导了自噬，减少了细胞内多胺水平，激活了Akt/mTOR信号通路，显著增加了LC3的脂化和SSAT/PAO表达 ^[5]。

体内实验中，Epibrassinolide（0-720μg/kg/天；40天）可减小SW480来源的SCID小鼠的肿瘤体积和直径，并降低血清CEA水平^[6]。 Epibrassinolide（1μM；24 小时；5mL/孔水溶液暴露）可逆转乙醇在斑马鱼胚胎中诱导的行为缺陷，并恢复 GSH/GSSG氧化还原平衡^[7]。

实验参考方法 Experimental Reference Method

Cell experiment [1]:
Cell lines	SW480 and DLD-1 colon cancer cells
Preparation Method	Human colon cancer cell lines SW480 (CCL228) and DLD-1 (CCL221) were used in this experiment. The DLD-1 cells were grown in McCoy’s 5A medium, and the SW480 cells were grown in MEM medium. All the media were supplemented with 10% fetal bovine serum, 1000U/ml penicillin, and 10μg/mL streptomycin. The cells were cultured at 37°C in humidified 5% CO₂ incubator. Each colon cancer cell line was seeded at a density of 1×10⁵cells/well in 6-well plates and treated with 25μM Epibrassinolide for 48h. The polyamine content of each sample was determined by high-pressure liquid chromatography. Autophagy induction was determinated by acridine orange staining. Proteins were extracted for Immunoblotting analysis.
Reaction Conditions	25μM; 48h
Applications	Treatment of SW480 and DLD-1 colon cancer cells with Epibrassinolide induced autophagy, depleted intracellular polyamines, activated Akt/mTOR signaling, and significantly increased LC3 lipidation and SSAT/PAO expression.
Animal experiment [2]:
Animal models	SCID mice
Preparation Method	A total of 18 female, two weeks age, severe combined immunodeficiency (SCID) mice were used in the experiments. Experimental groups were as follows: Healthy mice receiving Epibrassinolide, tumor bearing control group, tumor bearing vehicle treated group, tumor bearing 240μg/kg/day Epibrassinolide treated group, tumor bearing 480μg/kg/day Epibrassinolide treated group, tumor bearing 720μg/kg/day Epibrassinolide treated group. 7×10⁶ SW480 colon cancer cells were inoculated with 200µl of matrigel into the right limb cavities of mice. Epibrassinolide was intraperitoneally injected consecutively for 40 days. After incubation period, SW480 tumor sizes became visible in mice. Tumor sizes of the mice divided into groups were measured with the help of an electronic caliper every two days. The mice were weighed at daily intervals of 5 days before the daily Epibrassinolide injections on the precision balance and their weights were noted. Before the mice were sacrificed, they were anesthetized with isofluorane and 500µl of blood was collected from the jugular vein of the mice, and serum was preserved for further ELISA experiments. The mice were then sacrificed, their tumors were removed and their pictures were taken.
Dosage form	0–720μg/kg/day; 40 days; i.p.
Applications	Epibrassinolide reduced tumor volume and diameter, and decreased the CEA level in the serum in SW480-derived xenografts in SCID mice.
