Cell viability was determined by methylthiazolyldiphenyl- tetrazolium bromide (MTT) method, the cell cycle distribution was detected by flow cytometry, mitochondrial membrane potential was detected by mitochondrial membrane potential test kit, apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) method, and the proteins expression of proliferating cell nuclear antigen (PCNA) and G₁/S specific cyclin D1 (cyclin D1) were detected by immunoblotting. RNA-Seq was conducted in the hinokiol-treated cells. The mRNA expression of yes-associated protein delta (YAP) was detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR). The proteins expression of phosphor-YAP (p-YAP) and nuclear YAP were detected by immunoblotting, the nuclear distribution of YAP protein was detected by immunofluorescence in the cells with or without treated with the mammalian STE20-like kinase 1/2 (MST1/2) inhibitor (XMU-MP-1), hinokiol, and XMU-MP-1+hinokiol. Statistical analysis of the data was conducted using GraphPad Prism 8.0 software. <b>Resluts</b> Compared with the control group, the cell viablity of CNE1 cells, the levels of mitochondrial membrane potential, the proteins expression of PCNA and cyclin D1 in hinokiol treatment groups were markedly decreased (all <i>P</i> values<0.05), while the proportion of G₀/G₁ phase cells and the ratio of TUNEL-positive cells were significantly increased (both <i>P</i> values<0.05). Transcriptome analysis showed that differential genes were mainly enriched in Wnt signaling pathway, tumor necrosis factor pathway, and Hippo signaling pathway. The mRNA level of YAP and the protein expression of YAP in the nucleus were decreased and the level of p-YAP protein was increased in cells treated with hinokiol, which were significantly different from control group (all <i>P</i> values<0.05). Compared with the hinokiol group, XMU-MP-1+hinokiol groups showed the decrease of p-YAP protein expression (1.157±0.076 <i>vs</i> 0.479±0.038, <i>t</i>=37.120, <i>P</i><0.05), the increase of YAP protein expression in the nucleus (0.143±0.012 <i>vs</i> 0.425±0.031, <i>t</i>=29.181, <i>P</i><0.05), the reduced proportion of cells in G₀/G₁ phase [(72.494±3.309)% <i>vs</i> (58.747±2.865)%, <i>t</i>=17.265, <i>P</i><0.05], and the decrease of apoptosis ratio [(53.158±3.376)% <i>vs</i> (29.621±2.713)%, <i>t</i>=28.584, <i>P</i><0.05]. <b>Conclusion:</b> Hinokiol can arrest the cell cycle and induce the cell apoptosis of CN","PeriodicalId":23987,"journal":{"name":"Zhonghua er bi yan hou tou jing wai ke za zhi = Chinese journal of otorhinolaryngology head and neck surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141535473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the Chinese clinical practice guideline of auditory neuropathy (version 2022), these patients divided into two groups: the normal hearing group (PTA Normal, PTA^N group, the average hearing threshold<20 dB HL) and the mild hearing loss group (PTA Mild hearing loss, PTA^M group, the average hearing threshold between 20-35 dBHL). The audiology characteristics, clinical features, and follow-up were analyzed. Data analysis was conducted using GraphPad Prism 8 and SPSS 20.0 software. <b>Results:</b> A total of 75 AN with normal hearing or mild hearing loss were included in this study. The PTA^N group consisted of 19 patients (38 ears), including 12 males and 7 females. The average onset age was (16.9±4.5) years old, while the test age was (22.1±5.8) years old for PTA^N group. The PTA^M group consisted of 56 patients (112 ears), including 29 males and 27 females. The average onset age was (16.2±7.9) years old, while the test age was (23.9±9.0) yeas old for PTA^M group. The average hearing threshold of low frequency (0.125-0.5 kHz) was significantly decreased. ABR disappeared in 86.00% (126/150) of the patients. The speech recognition rate was 71.80±22.44% in the PTA^N group and 58.08±29.28% in the PTA^M group.-SP/AP was 0.98±0.47 in the PTA^N and 1.07±0.63 in PTA^M group; 40 (53.33%) patients had tinnitus. 29 patients (58 ears) were followed up, including 10 patients (20 ears) in the PTA^N group and 19 patients (38 ears) in the PTA^M group. There was no significant change in hearing threshold in short-term follow-up (<3 years). With the extension of the disease duration (>3 years), the PTA^N group tended to decrease at low frequency, and the PTA^M group decreased at high frequency first. The hearing threshold at 0.25 kHz in the PTA^N group and 4 kHz in the PTA^M group decreased significantly. <b>Conclusions:</b> AN patients with normal hearing or mild hearing loss exhibit abnormal results in audiological examination results, including ABR, electrocochleography and speech discrimination score. A combination of audiological tests should be used to make the diagnosis of AN. With the progression of the disease, AN with normal hearing or mild hearing loss tends to decrease.</p>","PeriodicalId":23987,"journal":{"name":"Zhonghua er bi yan hou tou jing wai ke za zhi = Chinese journal of otorhinolaryngology head and neck surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141176443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
