JGH:TMSB10是一种可以预测胃癌侵袭能力和血管生成的生物标志物

2021-11-19 MedSci原创 MedSci原创

本项研究证实TMSB10有望成为诊断GC的潜在预后预测生物标志物和潜在的治疗靶点。

      胃癌 (GC) 是中国男性中第二常见的恶性肿瘤,并且仍然是发展中国家癌症相关死亡的主要原因之一。尽管近年来,胃癌患者的发病率和死亡率呈下降趋势,而且胃癌早期诊断率低,5年生存率仍低于20%,中位生存率大约10个月。因此,临床上迫切需要研究GC的机制,发现预后生物标志物并对GC早期诊断的潜在治疗靶点进行研究。胸腺素β10(Tβ10)作为β胸腺素家族的一员,主要参与细胞内肌动蛋白的隔离。研究表明Tβ10表达改变与乳腺癌、食管癌、肝癌、胆管癌、卵巢癌等恶性肿瘤关系密切。根据癌症类型的不同,Tβ10呈现出不同的表达状态,而且具体作用机制尚未明确。本项研究旨在确定TMSB10在人类GC组织中的表达情况,并评估它是否与GC患者的临床病理特征和预后相关。

      研究人员首先在胃癌患者的组织标本中进行了TMSB10 特异性染色,比较了GC患者与非GC患者组织中TMSB10表达的差异,然后对所有受试者的临床数据以及人口学资料进行了统计分析,以期找出与TMSB10表达相关危险因素,为了探究影响TMSB10表达差异的具体信号通路,研究人员还通过体外和离体GC细胞的TMSB10敲低/过表达来对TMSB10在调节肿瘤生长、侵袭和血管生成中的作用和潜在机制进行评估。

 

      研究结果发现在GC细胞和组织中观察到 TMSB10 蛋白表达的显著,这与GC患者的晚期肿瘤分期和淋巴结 (LN) 转移有关。此外,预后分析表明,具有高TMSB10表达的 GC患者的生存期显着缩短,并且是预测GC患者总体生存率差的重要因素。此外,TMSB10过表达促进了GC细胞的增殖和血管生成。

 

       本项研究证实TMSB10有望成为诊断GC的潜在预后预测生物标志物和潜在的治疗靶点,这将促进针对 GC 的新型治疗策略的开发。
