How to use

In Vitro:

Siomycin A (0-10 µM; 24-72 hours; K562, MCF7 and MiaPaCa-2 cells) treatment markedly reduces cell viability in a dose-dependent and a time-dependent association in K562, MCF7 and MiaPaCa-2 cells. Among the three cell lines, the IC50 of the human leukemia K562 cells is the lowest at 6.25 µM at 24 h, while that for the human pancreatic cancer MiaPaCa-2 cells is 6.38 µM. However, the IC50 of the human pancreatic cancer MiaPaCa-2 cells at 48 and 72 h are the lowest of the three cell lines, which are 0.76 and 0.54 µM, respectively. Siomycin A (0-10 µM; MiaPaCa-2 cells) treatment has potent proapoptotic effect in MiaPaCa-2 cells. Siomycin A (0-10 µM; 24 hours; MiaPaCa-2 cells) treatment significantly reduces the expression levels of MMP-2, MMP-9 and α-tubulin protein in the MiaPaCa-2 cells.

In Vivo:

Siomycin A (1 µM; subcutaneous injection; for 4 weeks; male Balb/c nude mice) pretreatment decreases tumour growth in an in vivo mouse model.
