Selective growth inhibition of human malignant melanoma cells by syringic acid-derived proteasome inhibitors
Cancer Cell Int
BACKGROUND: It has been shown that proteasome inhibition leads to growth arrest in the G1 phase of the cell cycle and/or induction of apoptosis. However, it was found that some of these inhibitors do not induce apoptosis in several human normal cell ...
