Many hematopoietic cells undergo apoptosis when deprived of specific cytokines. Lipocalin 24p3, reported to be induced in hematopoietic cells by interleukin 3 (IL-3) depletion, induces hematopoietic cell apoptosis despite the presence of IL-3. As granulocyte colony stimulating factor (G-CSF) depletion also induces the apoptosis of G-CSF-dependent cell line cells, we examined the effect of 24p3 on the apoptotic function induced by G-CSF depletion. 24p3 was induced by the depletion of IL-3, but not G-CSF, in cytokine-dependent cell lines. Although 24p3 suppressed growth induced by IL-3, it did not influence G-CSF-dependent cell growth. These observations show that 24p3 is not involved in the G-CSF withdrawal-induced apoptosis, although it is essential in IL-3 withdrawal-induced apoptosis.
