目的
2
探究冬凌草甲素(ORI)对人食管鳞状细胞癌(ESCC)细胞KYSE-150内谷胱甘肽代谢网络(GMN)中13个主要代谢物的影响,包括半胱氨酸(Cys)、高半胱氨酸(HCys)、谷胱甘肽(GSH)、甲硫氨酸(Met)、
S
-腺苷高半胱氨酸(SAH)、胱硫醚(Cysta)、甘氨酸(Gly)、谷氨酸(Glu)、谷氨酰胺(Gln)、谷氨酰半胱氨酸(GC)、半胱氨酰甘氨酸(CG)、
O
-乙酰丝氨酸(OAS)和丝氨酸(Ser)。
方法
2
首先,采用细胞计数试剂盒(CCK-8)法检测ORI对人ESCC细胞KYSE-150活性的影响,以半抑制浓度(IC
50
)作为后续细胞培养的干预浓度。将KYSE-150细胞按照不同的培养时间分为0 h、12 h、24 h、36 h组,以0 h组作为对照(空白培养液),12 h、24 h、36 h组采用含ORI的培养液(12.5 μmol/L)对细胞进行相应时间的干预。然后,采用超声提取法提取细胞中的内容物,
利用液相色谱-质谱(LC-MS)法直接检测ORI与GMN中巯基代谢物结合形成的缀合物,利用LC-MS结合化学衍生的方法检测13个目标GMN代谢物。最后,通过活性氧(ROS)检测试剂盒检测细胞提取物中ROS水平。
结果
2
①ORI对人ESCC细胞KYSE-150有明显的抑制作用,IC
50
值为12.5 μmol/L。②与0 h组相比,ORI干预后的3组KYSE-150细胞内GMN中的大部分代谢物(CG、GSH、GC、Cly、Glu、SAH、Cys、OAS和Cysta),尤其是含巯基的代谢物(CG、GSH、GC和Cys),浓度呈现先升高后下降的趋势。③在细胞提取物中检测到ORI与Cys、HCys、GSH这3个巯基内源性代谢物反应生成的缀合物。④ORI干预后KYSE-150细胞内ROS水平持续升高。
结论
2
ORI可能通过影响KYSE-150细胞内GMN中代谢物水平引起ROS的蓄积,进而降低细胞对抗脂质过氧化和氧化应激的能力。
Objective
2
To investigate the effects of oridonin (ORI) on the 13 metabolites within the glutathione metabolic network (GMN) in human esophageal squamous cell carcinoma (ESCC) KYSE-150 cells, including cysteine (Cys), homocysteine (HCys), glutathione (GSH), methionine (Met),
S
-adenylyl homocysteine (SAH), cystathionine(Cysta), glycine (Gly), glutamic acid (Glu), glutamine (Gln), glutamylcysteine (GC), cysteinylglycine (CG),
O
-acetyl-serine (OAS) and serine (Ser).
Methods
2
Firstly, the Cell Counting Kit-8 (CCK-8) assay was utilized to assess the effect of ORI on the viability of KYSE-150 cells, and the half-maximal inhibition concentration (IC
50
) was used as the intervention concentration for subsequent cell culture. KYSE-150 cells were then divided into 0 h, 12 h, 24 h, and 36 h groups based on different culture time. The 0 h group was set as control (blank culture medium), and the 12 h, 24 h and 36 h groups were treated with culture medium containing ORI (12.5 μmol/L) for corresponding time. Subsequently, cell contents from each group were extracted via ultrasonication. Liquid chromatography-mass spectrometry (LC‑MS) method was employed for the identification of ORI and GMN thiol adducts, while LC-MS combined with chemical derivatization method was utilized for detecting the 13 target metabolites. Finally, reactive oxygen species (ROS) levels of cellular extracts w
ere quantified using a ROS assay kit.
Results
2
①ORI had a significant inhibitory effect on human ESCC KYSE-150 cells with an IC
50
value of 12.5 μmol/L. ②Compared with the 0 h group, the concentrations of most metabolites within the GMN of KYSE-150 cells (CG, GSH, GC, Cly, Glu, SAH, Cys, OAS and Cysta), especially thiol-containing metabolites (CG, GSH, GC and Cys), showed a trend of initial increase followed by decrease after intervention with ORI. ③Three conjugates resulting from the binding of ORI to thiol-containing metabolites (Cys, HCys and GSH) were identified in cellular extracts. ④The level of ROS in KYSE-150 cells continued to increase after ORI intervention.
Conclusion
2
ORI may induce ROS accumulation by modulating metabolite levels within the GMN of KYSE-150 cells, consequently impairing the cells' capacity to counteract lipid peroxidation and oxidative stress.
