Abstract
The role of bone morphogenetic proteins in the progression and metastasis of prostate cancer is a topic that has undergone extensive research. This study investigates the role of BMP member growth and differentiation factor 9 (GDF-9) in the progression of this disease. GDF-9 was over-expressed and knocked-down in PC-3 cells, respectively. Furthermore, along with the use of a generated recombinant GDF-9 protein, these cells were then analyzed for any changes in their invasiveness and expression of epithelial–mesenchymal transition (EMT) associated genes. GDF-9 was shown to promote the invasiveness of PC-3 cells together with an induction in the expression of genes including SNAI1, RhoC, ROCK-1, and N-cadherin, while reducing levels of E-cadherin. These expression changes are characteristic of the onset of EMT, and resulted in the cells having a more mesenchymal-like morphology. Treating these cells with activin-like kinase-5 (ALK-5) inhibitor, demonstrated that GDF-9 induced up-regulation of these molecules was ALK-5 dependant. This study shows that in PC-3 cells, GDF-9 signaling via ALK-5, can promote cell invasiveness via a complex network of signaling molecules that work together to trigger the process of EMT, and thereby aid in the aggressiveness and progression of prostate cancer cells.
