PRDI-BF1 and RIZ homology (PR) domain zinc finger protein 14 (PRDM14) contains a PR domain related to the SET methyltransferase domain and zinc finger motifs. PRDM14 maintains stemness in embryonic stem cells and primordial germ cells via epigenetic mechanisms. PRDM14, however, is not expressed in normal differentiated tissues. We and other groups previously reported that PRDM14 expression is markedly higher in some types of cancers compared to the corresponding normal tissues. PRDM14 confers stem cell-like characteristics upon cancer cells, such as sphere formation, dye efflux, chemotherapy resistance, proliferation, and distant metastasis. Cancer stem cells (CSCs) are thought to be responsible for tumor initiation, drug and radiation resistance, invasive growth, metastasis, and tumor relapse, which are the primary causes of cancer-related deaths. Because CSCs are also thought to be resistant to conventional therapies, an effective and novel therapeutic approach for CSCs is imperative.RNAi silencing of PRDM14 expressed by breast and pancreatic cancer cells reduced tumor size and distant metastasis of these cells in nude mice. Inhibition of PRDM14 expression by cancer cells may be an effective and radical therapy for solid cancers. In this chapter, we discuss methods for studying CSC-like properties in cancer cells and describe the use of siRNA with a drug delivery system by systemic injection in vivo.

The PRDI-BF1 and RIZ (PR) domain zinc finger protein 14 (PRDM14) is upregulated in approximately 60% of breast cancers, some of which exhibit gene amplification. In contrast, PRDM14 is not expressed in normal, and differentiated tissues. PRDM14+ breast cancer cells are resistant to chemotherapy drugs, are tumorigenic, and metastasize to the lungs. It is commonly assumed that genes that are overexpressed in cancers, such as PRDM14, are effective targets for new therapies that specifically abrogate the expression of these genes. RNA interference of PRDM14, a gene expressed by breast cancer cells, reduced the size of tumors and lung metastases in nude mice. In this chapter, we introduce the concept and methods to develop and apply systematically injected small interfering RNA therapy for breast cancer models in vivo.
