Am J Otolaryngol:外听毛细胞损伤早期检测中,利用快蛋白作为一种预测标记的研究

2018-07-28 AlexYang MedSci原创

最近,有研究人员评估将快蛋白作为一种鉴定早期耳毒性生物标记的情况。研究包括了47只小鼠,并随机分配到5个小组中:分别为低剂量(LAG)或者高剂量(HAG)丁胺卡那霉素(分别为200和600mg/kg/day, 为期10天)、低剂量(LCIS)或者高剂量(HCIS)铂化合物组(单次剂量分别为 5和15mg/kg,为期 3天)以及对照组(N=8)。在试验末期,研究人员对畸变产物诱发耳声发射(DPOAE

最近,有研究人员评估将快蛋白作为一种鉴定早期耳毒性生物标记的情况。研究包括了47只小鼠,并随机分配到5个小组中:分别为低剂量(LAG)或者高剂量(HAG)丁胺卡那霉素(分别为200和600mg/kg/day, 为期10天)、低剂量(LCIS)或者高剂量(HCIS)铂化合物组(单次剂量分别为 5和15mg/kg,为期 3天)以及对照组(N=8)。在试验末期,研究人员对畸变产物诱发耳声发射(DPOAE)进行了测量来评估听力情况,并在麻醉情况下收集了血液和耳组织样本。研究人员还通过ELISA确定了快蛋白的水平,并利用组织学评估了耳蜗损伤情况。

研究发现,平均血清快蛋白水平在对照、LCIS、 HCIS、LAG和HAG组中分别为377.0±135.3、411.3±73.1、512.6±106.0、455.0±74.2和 555.3±47.9pg/ml。在对照-LCIS-HCIS组之间(p=0.031)和对照-LAG-HAG组之间(p=0.003)的快蛋白水平上,均存在显著的差异。同时,在低、高剂量铂化合物和丁胺卡那霉素处理组之间,快蛋白水平也存在显著的差异(分别为p=0.028和p=0.011)。另外,与对照组相比,所有处理组在4, 6和8kHz具有显著更低的DPOAE结果。然而,LAG, HAG, LCIS和HCIS组比对照组均具有显著更高的耳蜗损伤评分(P<0.05)。

最后,研究人员指出,更高剂量的铂化合物和丁胺卡那霉素与快蛋白水平急剧的增加和耳蜗损伤相关。他们的结果表明了快蛋白是耳蜗损伤有希望的早期预测因子。

Mol Med Rep:microRNA 183参与了Notch信号途径抑制的听毛细胞分化和再生

损伤后的听觉毛细胞再生对听力重建是非常重要的。Notch信号途径参与了内耳发育和细胞分化的调控。之前的证据表明microRNA(miR)-183在内耳中具有相似的作用。然而,Notch信号在哺乳动物动物中是怎样在听毛细胞再生中作用和是否Notch信号和miR-183之间具有交互作用仍旧不清楚。最近,有研究人员利用一个庆大霉素诱导的耳蜗损伤小鼠模型进行了相关研究。庆大霉素诱导的听毛细胞损伤激活了No

Nat Commun:CIB2可与TMC1和TMC2互作,并且在听毛细胞中力传导中是必要的

内耳表皮毛细胞可以通过静纤毛的挠曲检测声音,静纤毛是类似微绒毛的突出部分并且以不同分级的高度成排排列。钙和整合素结合蛋白2对听力和定位到静纤毛是必要的,但是它的准确的功能还是未知的。最近,有研究人员鉴定了2个突变小鼠系,1个缺乏钙和整合素结合蛋白2,另1个携带人类耳聋相关Cib2突变,并且2个突变西小鼠都是耳聋的,在听毛细胞中没有力传导,尽管力传导通道连接依然存在。另外,力传导的更短的成排静纤毛在

Cell Death Dis: 细胞自噬对小鼠听力是必要的

听力损失是人类感官障碍中最为普遍的一种障碍。听毛细胞(HCs)是在胚胎晚期分化和出生后阶段通过有丝分裂产生的,听毛细胞的损伤是导致听力损失的主要原因。在哺乳动物耳蜗中,并不存在可以再生的可测量的听毛细胞,并且听毛细胞功能的保持对于听力的维持非常重要。最近,有研究人员在小鼠中产生了一个缺陷型突变体,该突变体基因为细胞自噬相关的基因5(Atg5),该基因对细胞自噬是不可或缺的。研究人员在听毛细胞中调查
