Abstract：
BACKGROUND:Noise-induced hearing loss (NIHL) is a multifactorial disease, and dysregulation of oxidative stress is universally acknowledged as one crucial pathogenic factor for this disease. Recently studies have found the LncRNA HOTAIR is involved in the alteration of oxidative stress level, cell proliferation, cell cycle progression, and apoptosis. Considering the effects of lncRNA HOTAIR in cellular oxidative stress, we sought to investigate the influence of lncRNA HOTAIR variants on the risk of NIHL. METHODS:To explore the effects of HOTAIR polymorphisms on individual susceptibility to NIHL, We performed genotyping of three tagSNPs (rs874945, rs4759314 and rs7958904) in HOTAIR gene in a Chinese population which consists of 570 NIHL cases and 570 controls. The luciferase assays were further performed to investigate the regulatory function of HOTAIR tagSNPs. RESULTS:Our results revealed individuals with the G allele of HOTAIR tagSNP rs4759314 and the haplotype (rs874945, rs4759314 and rs7958904) are associated with an increased risk of NIHL in a Chinese population. Meanwhile, the rs4759314 G allele could significantly increase the expression of lncRNA HOTAIR. CONCLUSIONS:The genetic polymorphism within HOTAIR gene may play a crucial role in the occurrence and development of NIHL.
