Abstract
Cellular transformation is a widely used method to artificially induce cells to form tumours in vivo. Here, we describe the methodology for malignant transformation of mouse embryonic fibroblasts (MEFs) for transplantation into immunodeficient nude mice, as used in Leong et al. (2013). The two-step process involves: 1) down-regulation of Trp53 expression using a short hairpin RNA (shRNA); and 2) overexpression of the oncogenic HRasV12 protein. Reduction of Trp53 expression leads to cell immortalisation, and the subsequent overexpression of oncogenic HRasV12 results in malignant transformation of a cell.
