Aberrant allelic-switch of antisense lncRNA IRAIN may be an early diagnostic marker in laryngeal cancer.

ABSTRACT: Laryngeal carcinoma is a common head and neck malignancy, however, the molecular mechanism of the disease has not yet been elucidated. The present study aimed to investigate the role of IGF1R antisense imprinted non-protein coding RNA (IRAIN) long non-coding (lnc)RNA in laryngeal carcinoma. In total, specimens of healthy pharynx tissue from 6 healthy individuals, carcinoma tissue and paracancerous tissue from 37 patients with laryngeal carcinoma were used in this study. The single nucleotide polymorphism (SNP) rs8034564 was used to distinguish the two parental alleles of IRAIN. DNA and RNA were extracted from tissue specimens and the IRAIN allelic gene was sequenced. Reverse transcription-quantitative PCR was used to determine the expression levels of IRAIN and Insulin-like growth factor 1
