Transgelin-2在癌症和哮喘中的生化和临床意义
2019/11/12
摘要
Transgelin-2被认为是一种肌动蛋白结合蛋白，可诱导肌动蛋白凝胶化并调节肌动蛋白的细胞骨架。然而，最近已证明transgelin-2通过充当细胞外金属硫蛋白-2的受体来松弛气道平滑肌细胞的肌球蛋白细胞骨架。从临床的角度来看，这些结果支持transgelin-2作为癌症和哮喘等疾病的有希望的治疗靶标。Transgelin-2的抑制可防止肌动蛋白凝胶化，从而防止癌细胞增殖、侵袭和转移。相反地，用特定的激动剂激活transgelin-2可使气道平滑肌松弛并降低哮喘的肺部抵抗力。在本文中，我们综述了关于transgelin-2生化特性的新研究，并讨论了它们对免疫、致癌和呼吸系统疾病治疗的临床意义。

Abstract
Transgelin-2 has been regarded as an actin-binding protein that induces actin gelation and regulates actin cytoskeleton. However, transgelin-2 has recently been shown to relax the myosin cytoskeleton of the airway smooth muscle cells by acting as a receptor for extracellular metallothionein-2. From a clinical perspective, these results support transgelin-2 as a promising therapeutic target for diseases such as cancer and asthma. The inhibition of transgelin-2 prevents actin gelation and thereby cancer cell proliferation, invasion, and metastasis. Conversely, the activation of transgelin-2 with specific agonists relaxes airway smooth muscles and reduces pulmonary resistance in asthma. Here, we review new studies on the biochemical properties of transgelin-2 and discuss their clinical implications for the treatment of immune, oncogenic, and respiratory disorders.
