Biological role and clinical implications of homeobox genes in serous epithelial ovarian cancer

Homeobox (HOX) genes are a family of transcription factors that are essential regulators of development. HOX genes play important roles in normal reproductive physiology, as well as in the development and progression of serous carcinomas, the predominant and most aggressive subtype of epithelial ovarian cancer (EOC). This review discusses aberrant HOX gene expression in serous EOC and its impact on tumor development and progression. Further identification of HOX target genes may facilitate the development of novel diagnostic and therapeutic strategies to improve the prognosis of patients with serous EOC. (C) 2016 Elsevier Inc.
