腫瘤基因調控研究-梁有志

實驗室名稱:腫瘤基因調控研究室

主持人:梁有志老師


過去的成果:

  本實驗室過去大多在開發抗發炎及抗癌的天然藥物,探討天然物經由何種訊息傳遞路徑或基因調控,達到抗發炎及抗癌的作用。其中,意外發現中草藥蛇床子素(osthole)可經由活化AMPK而增加骨骼肌吸收葡萄糖,而具有降血糖的功效,此成果獲得美國及本國專利。

  近幾年我們專注在一群新穎C3H鋅指蛋白質(CCCH zinc finger)家族成員,發現在人類大腸直腸癌組織中,某些C3H鋅指蛋白質的基因表現低落;某些又過度表現。因此,我們以分子生物學的方法來探討這些C3H鋅指蛋白質在腫瘤生長過程中所扮演的角色。
