- Abstract
- Sesquiterpene lactone compounds have received considerable attention in pharmacological research due to their therapeutic effects including anti-cancer and anti-inflammatory activities. In this report, we investigated the effect of arsantin, a sesquiterpene lactone compound present in Artemisia santolina, on cellular differentiation in the human promyelocytic leukemia HL-60 cell culture system. Arsantin significantly induced HL-60 cell differentiation in a concentration-dependent manner. Cytofluorometric analysis indicated that arsantin induced HL-60 cell differentiation predominantly into granulocytes. Both PKC and MAPK inhibitors suppressed the HL-60 cell differentiation induced by arsantin. Moreover, treatment with arsantin increased protein levels of PKC alpha and PKC beta II isoforms, and also induced increased protein levels and phosphorylation form of MAPKs in HL-60 cells. Importantly, arsantin synergistically enhanced differentiation of HL-60 cells in a dose-dependent manner when combined with either low doses of 1,25-(OH)(2)D-3 or ATRA. The ability to enhance the differentiation potential of 1,25-(OH)(2)D-3 or ATRA by arsantin may improve outcomes in the therapy of acute promyelocytic leukemia.
