Tubeimoside-1 (TBMS1) is one of the extracts of rhizoma bolbostemmae, which has remarkable anti-cancer function in the treatment of esophagus and gastric cancer in traditional Chinese medicine. However the mechanisms of its anti-cancer function is remain unclear. In this study, we demonstrate that TBMS1 could inhibit cell growth and metastasis in glioblastoma. MET is a member of the receptor tyrosine kinase family, which amplifies frequently in various human cancers. As an important proto-oncogene, multiple inhibitors have been developed for the therapy of cancers. Here, we found TBMS1 could reduce/decrease the protein level of MET via increasing its Ubiquitination degradation. Therefore, TBMS1 is a promising compound for the treatment of glioblastoma and an inhibitor of MET.
冬凌草甲素（TBMS1）是冬凌草的提取物之一，在中医治疗食管癌和胃癌方面具有显著的抗癌功能。然而，其抗癌功能的机制尚不清楚。在这项研究中，我们证明 TBMS1 可以抑制神经胶质瘤中的细胞生长和转移。MET 是受体酪氨酸激酶家族的成员，在各种人类癌症中经常扩增。作为一个重要的原癌基因，已经开发出多种抑制剂用于癌症的治疗。在这里，我们发现 TBMS1 可以通过增加其泛素化降解来降低/减少 MET 的蛋白水平。因此，TBMS1 是治疗神经胶质瘤和 MET 抑制剂的一种有前途的化合物。
