实验参考方法

Cell experiment [1-4]:

Cell lines

Colorectal cancer cell line HCT116 cells; MCF-7 cells; Hela cells; Normal rat kidney cells (NRK); MDA-MB-231 cells

Preparation method

The solubility of this compound in DMSO is >4.7mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

5 μg/ml, 1 μg/ml; 3-40 h; 37℃

Applications

BFA treatment (15 h or 40 h) of normal rat kidney (NRK) cells caused dramatic swelling of the Endoplasmic Reticulum (ER) and shifted its localization to the periphery of the cells. BFA affected Golgi structure and MT and actin organization. BFA preferentially induced cell death in MDA-MB-231 suspension cultures with the EC50 of 0.016 μg/mL. BFA effectively inhibited clonogenic activity and the migration and matrix metalloproteinases-9 (MMP-9) activity of MDA-MB-231 cells by down-regulating the breast CSC marker CD44 and anti-apoptotic proteins Bcl-2 and Mcl-1, as well as the reversal of epithelial-mesenchymal transition. Treatment with BFA (1 μg/ml) induced p53 expression in MCF-7 cells and Hela cells. In colorectal cancer cell line HCT116 cells, BFA induced cells apoptosis.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

Brefeldin A (BFA) is an inhibitor of ATPase with IC50 value of 0.2 μM [1]
ATPase is a chemical enzyme which is essential in the ADP/ATP exchange which process provides chemical potential energy. ATP supplies the energy for many physiological activities such as importing metabolites necessary for cell metabolism, exporting toxins, wastes, and solutes that can hinder cellular processes, cell proliferation, ER stress and so forth [2].
Treatment with BFA could attenuate stimulus-dependent hyperalgesia phenomenon via inhibiting vesicular exocytosis which process is important for ATP release [3]. When tested with cell line HEK293 cells (stably express wild-type (wt) CRELD2), BFA treatment nearly abolished the secretion of wtCRELD2 completely via inhibiting the transportation of proteins from the ER to the Golgi apparatus [4]. In MCF-7 cells and Hela cells, treatment with BFA induced p53 expression via inhibiting ATP which enhanced ER stress [5]. When treated with colorectal cancer cell line HCT116 cells, BFA treatment induced cells apoprosis by inhibiting ATP which functioned in the process of cellular vesicle trafficking [1].
BFA also is reported as an inhibitor for GTP/GDP exchange in a dose-dependent way, which is important in vesicular trafficking [6].
