Abstract
Macrophage colony-stimulating factor (M-CSF), also named colony-stimulating factor-1 (CSF-1), plays an important role in the process of proliferation and differentiation of the monocyte/macrophage lineage cells. Commonly, it is not easy to measure the expression of cellular M-CSF. However, recent studies have shown that M-CSF can be expressed at a high level in the cytoplasm and nuclei of some kinds of malignant tumors, which related to the poor prognosis. To explore the role and mechanism of nuclear M-CSF, in the present study we constructed the pCMV/nuc/M-CSF vector and transfected it into human HeLa nuclei. The results from our previous study indicated, M-CSF was stably expressed in HeLa nuclei, which were used as a model to determine the nuclear effects of M-CSF. There was a higher percentage of replicating nuclei in the transfected pCMV/nuc/M-CSF HeLa cells both in phase G1 and S. According to the data from the cell doubling time, antisense oligonucleotides and the experiments of the transplanted tumor in nude mice, nuclear M-CSF could promote the cell proliferation of HeLa cells both in vivo and in vitro. In conclusion, nuclear M-CSF could accelerate DNA replication and cell proliferation of cervical carcinoma.
