32D cells are murine myeloid cells that grow indefinitely in Interleukin-3 (IL-3). In these cells, the type 1 insulin-like growth factor (IGF-I) and granulocytic-colony stimulating factor (G-CSF) induce differentiation to granulocytes. 32D cells do not express insulin receptor substrate-1 (IRS-1) or IRS-2, docking proteins of the IGF-I receptor. Ectopic expression of IRS-1 in these cells inhibits differentiation, the cells become IL-3 independent and IGF-1 dependent and can form tumors in mice. 32D and 32D-derived cells offer a good model in which to study the expression profiles of Micro Rna (miR) related to sustained proliferation or differentiation. We present here the data obtained with miR micro-arrays and identify the miR that are regulated by IGF-1 or G-CSF and are associated with either differentiation or indefinite cell proliferation of 32D murine myeloid cells.

Abstract

32D cells are murine myeloid cells that grow indefinitely in Interleukin-3 (IL-3). In these cells, the type 1 insulin-like growth factor (IGF-I) and granulocytic-colony stimulating factor (G-CSF) induce differentiation to granulocytes. 32D cells do not express insulin receptor substrate-1 (IRS-1) or IRS-2, docking proteins of the IGF-I receptor. Ectopic expression of IRS-1 in these cells inhibits differentiation, the cells become IL-3 independent and IGF-1 dependent and can form tumors in mice. 32D and 32D-derived cells offer a good model in which to study the expression profiles of Micro Rna (miR) related to sustained proliferation or differentiation. We present here the data obtained with miR micro-arrays and identify the miR that are regulated by IGF-1 or G-CSF and are associated with either differentiation or indefinite cell proliferation of 32D murine myeloid cells.
