Emerging role of HOX genes and their related long noncoding RNAs in lung cancer

Abstract The transcription factor homeobox (Hox) proteins are the master regulator for the embryonic development. Studies have identified new functions for HOX in the regulation of metabolism and other primary cellular processes in humans. Their dysregulation has been observed in a variety of cancers and accumulating evidence has revealed the crucial role of HOX in cancer progression, metastasis, and resistance to therapy. HOX-related long non-coding RNAs (lncRNAs) became the most attracting lncRNAs recently that play critical role in gene regulation and chromatin dynamics in cancers. In this review, we explore the roles of HOX and their related lncRNAs in lung cancer, indicating HOX genes as potential therapeutic targets in lung cancer.
