Induction of Sp1-p53 DNA-binding heterocomplexes during granulocyte/macrophage colony-stimulating factor-dependent proliferation in human erythroleukemia cell line TF-1.
Stimulation of proliferation of the erythroleukemia cell line TF-1 with GM-CSF enhances HnudC protein and mRNA expression and treatment with antisense (but not sense) oligonucleotides to HnudC mRNA significantly reduces cell division.
In human erythroleukemia patient myeloid progenitor stem cells (TF-1) as well as chronic myelogenous leukemia cells (K562), granulocyte-macrophage colony-stimulating factor primes cells for apoptosis.
