Analysis of HOX Homeodomain Proteins and Gene Transcripts in the Epidermis

HOX homeodomain proteins are thought to be master developmental regulators of tissue patterning during embryogenesis. These DNA binding proteins also have diverse roles in adult cell function, and derangement of HOX genes has been associated with several types of cancer. In this chapter we present protocols for the immunohistochemical localization of HOX proteins in the epidermis. We also provide in situ hybridization protocols for detection of HOX gene mRNA transcripts in the epidermis.
