ABSTRACT

Alteration in the normal regulatory pathway of differentiation can lead to the induction of programmed cell death. Accordingly, some chemicals like staurosporine, nerve growth factor, pituitary adenylate cyclase activating peptide, and trimethyltin are shown to be able to induce differentiation in vitro, via different mechanisms in the PC12 cell line. Hence, understanding the details of the molecular mechanisms of differentiation induction by these small molecules are important for further application of these molecules in neurogenesis. Therefore, we sought to determine these signaling pathways, using gene regulatory networks analysis. Then, we have conducted a comparative analysis of the alterations in the gene expression pattern of the PC12 cell lines in response to these chemicals at the early stages. Based on the comparative analysis and previous knowledge, we have proposed the affected pathways during differentiation and apoptosis. Our findings could be useful in the development of protocols to reprogramming of neurons by such small molecules with high efficiency.
