Analysis of lncRNA-mRNA expression pattern in male textile workers with noise-induced hearing loss.

ABSTRACT: Background:Extracellular long non-coding RNA (lncRNA) has attracted increasing attention as a potential biomarker to indicate disease status and physiological process. It plays a unique role in pathogenesis, and may be a new potential biomarker, especially for chronic hearing loss. Early screening of NIHL susceptible population is of great significance in reducing the incidence of NIHL. Methods:The expression profiles of lncRNAs and mRNAs in serum of noise-induced hearing loss (NIHL) and exposure groups were detected by microarray technique in serum. The differentially expressed mRNAs was analyzed by GO and KEGG to identify related biological functions and signaling pathways. The top up-regulated and down regulated lncRNAs were identified by qRT-PCR. Results:A total of 2,072 differentially expressed lncRNAs (889 up-regulated and 1,183 down-regulated) were included in NIHL subjects compared to exposed group by using microarrays. GO enrichment and KEGG pathway analysis showed that the expression pattern of mRNAs in serum of NIHL was associated with noise exposure. LncRNAs were verified by qRT-PCR, namely, LOC101928211, LOC101928804, and BANCR. The expression of LOC101928211 and LOC101928804 in the NIHL group was significantly higher than that in the exposed group, while the expression of BANCR was obviously decreased (P<0.001). Conclusions:In this study, lncRNAs and mRNAs expression profile in NIHL was preliminarily investigated in silico. The newly discovered lncRNAs might be involved in the pathological process of hearing loss and may serve as potential biomarkers to indicate long-term noise exposure-induced hearing loss.

Project description:ImportanceIt is important to determine what frequencies and auditory perceptual measures are the most sensitive early indicators of noise-induced hearing impairment.ObjectivesTo examine whether hearing loss among shipyard workers increases more rapidly at extended high frequencies than at clinical frequencies and whether subtle auditory processing deficits are present in those with extensive noise exposure but little or no hearing loss.Design, setting, and participantsThis cross-sectional study collected audiometric data (0.25-16 kHz), survey questionnaires, and noise exposure levels from 7890 shipyard workers in a Shanghai shipyard from 2015 to 2019. Worsening hearing loss was evaluated in the group with hearing loss. Speech processing and temporal processing were evaluated in 610 participants with noise exposure and clinically normal hearing to identify early biomarkers of noise-induced hearing impairment. Data analysis was conducted from November to December 2020.Main outcomes and measuresLinear regression was performed to model the increase in hearing loss as function of cumulative noise exposure and compared with a group who were monitored longitudinally for 4 years. Auditory processing tests included speech-in-noise tests, competing sentence tests, dichotic listening tests, and gap detection threshold tests and were compared with a control group without history of noise exposure.ResultsOf the 5539 participants (median [interquartile range (IQR)] age, 41.0 [34.0-47.0] years; 3861 [86.6%] men) included in the cross-sectional analysis, 4459 (80.5%) were hearing loss positive and 1080 (19.5%) were hearing loss negative. In younger participants (ie, ≤40 years), the maximum rate of increase in hearing loss was 0.40 (95% CI, 0.39-0.42) dB per A-weighted dB-year (dB/dBA-year) at 12.5 kHz, higher than the growth rates of 0.36 (95% CI, 0.35-0.36) dB/dBA-year at 4 kHz, 0.32 (95% CI, 0.31-0.33) dB/dBA-year at 10 kHz, 0.31 (95% CI, 0.30-0.31) dB/dBA-year at 6 kHz, 0.27 (95% CI, 0.26-0.27) dB/dBA-year at 3 kHz, and 0.27 (95% CI, 0.27-0.28) dB/dBA-year at 8 kHz. In the 4-year longitudinal analysis of hearing loss among 403 participants, the mean (SD) annual deterioration in hearing was 2.70 (2.98) dB/y at 12.5 kHz, almost twice as that observed at lower frequencies (eg, at 3kHz: 1.18 [2.15] dB/y). The auditory processing scores of participants with clinically normal hearing and a history of noise exposure were significantly lower than those of control participants (eg, median [IQR] score on speech-in-noise test, noise-exposed group 1 vs control group: 0.63 [0.55-0.66] vs 0.78 [0.76-0.80]; P < .001).Conclusions and relevanceThese findings suggest that the increase in hearing loss among shipyard workers was more rapid at 12.5 kHz than at other frequencies; workers with clinically normal hearing but high cumulative noise exposure are likely to exhibit deficits in speech and temporal processing.
