Metallothionein RNA levels in HL‐60 cells Effect of cadmium, differentiation, and protein kinase C activation
Hanke T., Tyers M., Harley CB.
Metallothionein (MT) gene transcription is regulated in a developmental and tissue‐specific manner by metal ions and other agents. We examined MT expression in the human promyelocytic leukemia cell line HL‐60 during differentiation along macrophage and neutrophil lineages. All HL‐60 phenotypes showed similar basal levels of MT RNA with significant induction following exposure to Cd2+ but not activators of PKC. MT RNA did not correlate with growth state or with known levels of PKC activity, thus our data do not support a role for MT in HL‐60 differentiation or for PKC in MT expression.
