体外活性 | This study was designed to obtain the chemical fingerprint and to investigate the effect of Phyllanthus urinaria on telomerase activity and apoptotic pathways in the human nasopharyngeal carcinoma cell line (NPC-BM1). METHODS AND RESULTS: The polyphenol compounds in P. urinaria were investigated by HPLC/MS. Cell viability with the treatment of P. urinaria, gallic acid, ellagic acid, quercetin and cisplatin was detected by MTT assay. TUNEL assay, DNA fragmentation analysis and caspase3 activity were used to confirm apoptotic changes. Telomerase activity was determined using the TRAP assay. RNA isolation and RT-PCR were used to analyze the related genes expression. All experiments on treatments with P. urinaria from 0-3 mg/ml were carried out for 24 h. 5 major compounds including gallic acid, brevifolin carboxylic acid, corilagin, Phyllanthusiin C and ellagic acid were identified as a plant fingerprint by HPLC/MS. With the MTT assay, we demonstrated that P. urinaria, gallic acid and ellagic acid reduce cell viability. The apoptosis features showed DNA fragmentation and increased caspase-3 activity associated with the down-regulation of Bcl-2, but not of Bax, p53, and PCNA (proliferating cell nuclear antigen) in P. urinaria-treated NPC-BM1 cells. Furthermore, treatment of NPC-BM1 cells led to an inhibition of hTERT (human telomerase reverse transcriptase), hTP1 (human telomerase-associated protein 1) and c-myc mRNA expression and to decreased telomerase activity. CONCLUSIONS: This study suggests that P. urinaria induces the death of NPC-BM1 cells in vitro through the induction of apoptosis and inhibited telomerase activity. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
