IC?? & Target MMP-1MMP-3

体外研究Cordycepin is a potent inhibitor of IL-1β-induced chemokine production and MMP expression and strongly blocks the p38/JNK/AP-1 signalling pathway in RASFs. The effect of Cordycepin on cellular toxicity of RASFs is assessed using

MTT assay. Treatment of RASFs with Cordycepin (50 μM or 100 μM) for 24 h does not cause any significant change in

cell viability. However, cell viability is slightly decreased when cells are incubated with 100 μM Cordycepin for 48 h[1].

PROTOCOL

Cell Assay [1]RASFs (2×104 cells/well) are treated with various concentrations of Cordycepin (50 μM or 100 μM). After incubation for 1 h, 12 h and 24 h, cells are washed twice with PBS, MTT (0.5 mg/mL PBS) is added to each well and incubated at

37°C for 30 min. Formazan crystals formed are dissolved by adding DMSO (100 μL/well) and the absorbance is read at

570 nm using a microplate reader[1].
