In laryngeal cancer, HMGA1P6 (high mobility group at-hook 1 pseudogene 6) and HMGA1P7 (high mobility group at-hook 1 pseudogene 7) pseudogene transcripts were identified as possible miRNA sponges, allowing the increase of HMGA2 expression (high mobility group at-hook 2) and other oncogenic genes involved in proliferation and cell cycle progression, such as CCNB2 (cyclin B2) and WNT (proto-oncogene WNT) family member genes, and epithelial–mesenchymal transition, such as SNAIL (snail family transcriptional repressor) and TWIST1 (twist family BHLH transcription factor 1) genes [33]. Here, CCNB2 is linked to laryngeal carcinoma.
