Induction of human leukemia cell differentiation via PKC/MAPK pathways by arsantin, a sesquiterpene lactone from Artemisia santolina

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 PKCα and PKCβII 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Pharmacal Research Springer Journals

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 PKCα and PKCβII 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.
