一项刊登在国际杂志International Journal of Cancer上的研究报告中,来自路易斯安那州立大学的科学家们通过研究发现,一种常用于治疗2型糖尿病的药物—二甲双胍或能有效治疗缺少Nischarin蛋白的癌症。

研究者Alahari博士表示,蛋白Nischarin参与了多种机体生物学过程,其能扮演肿瘤抑制子的角色,我们队这种新型蛋白质的研究主要集中在乳腺癌上,这项研究中,我们发现,干扰Nischarin基因或能减缓乳腺的发育,增强肿瘤的生长和转移,同时还会抑制AMPK激酶的激活,AMPK在机体代谢过程中扮演着关键的角色,其被认为是代谢性疾病和某些癌症的治疗靶点,目前研究人员并不清楚二甲双胍的精确作用机制,但其似乎部分是通过激活AMPK的功能来发挥作用的。

临床资料显示,使用二甲双胍策略的糖尿病患者罹患癌症的风险相对较低,但这其中的可能性就是,这种治疗癌症的方法可能被证明是一种有效且尚未证实的治疗机会。研究者表示,二甲双胍能激活AMPK的功能,并强烈抑制并不表达功能性Nischarin蛋白的肿瘤的生长,这就表明,二甲双胍在治疗缺失Nischarin的肿瘤上具有非常大的价值。

研究者Alahari说道,相比Nischarin阳性的细胞而言,剔除Nischarin的肿瘤细胞中AMPK的活性较低,而二甲双胍疗法能够在缺失Nischarin的小鼠中有效激活AMPK的表达,同时二甲双胍还能抑制小鼠机体中肿瘤的生长;研究结果表明,干扰Nischarin或能促进乳腺肿瘤的发育,AMPK信号对于Nischarin所介导的乳腺肿瘤的抑制非常重要,且通过二甲双胍所介导的AMPK的激活能够抑制Nischarin缺失小鼠机体中乳腺肿瘤的生长。

本文研究结果具有一定的临床意义,因为Nischarin的表达在人类乳腺癌中会频繁下降,尤其是在三阴性乳腺癌患者机体中,且其与乳腺癌患者长期的生存率下降直接相关;最后研究者表示,本文研究结果表明,诸如二甲双胍等特定药物的有效性或会受到Nischarin表达的影响,这也能够帮助识别出能因二甲双胍等疗法获益的患者群体,Nischarin的表达或能作为一种特殊的生物标志物来帮助指导患者的治疗,其能帮助有效识别因AMPK激活疗法而获益的患者亚群。
