科研要趁早!东北本科团队发现脂肪肝新药

2017-10-09 石 岩 环球医学

“搞科研是专家、教授的事儿”,这种想法已经过时了,现在有越来越多的本科团队加入到科学研究的大军中,并且他们取得的成绩令许多专业的研究者汗颜。近日,一个东北大学的本科生团队研究发现了治疗非酒精性脂肪肝的药物,并凭借此成果荣获2017全国大学生生命科学创新创业大赛一等奖。这个本科团队从2015年起,在教师郭闯的指导下应用铁螯合剂对糖尿病模型小鼠进行腹腔注射处理,多次试验证实铁螯合剂对非酒精性脂肪肝变性

“搞科研是专家、教授的事儿”,这种想法已经过时了,现在有越来越多的本科团队加入到科学研究的大军中,并且他们取得的成绩令许多专业的研究者汗颜。近日,一个东北大学的本科生团队研究发现了治疗非酒精性脂肪肝的药物,并凭借此成果荣获2017全国大学生生命科学创新创业大赛一等奖。

这个本科团队从2015年起,在教师郭闯的指导下应用铁螯合剂对糖尿病模型小鼠进行腹腔注射处理,多次试验证实铁螯合剂对非酒精性脂肪肝变性有明确的减轻作用,在减少动物血脂等方面也有重要意义。他们的研究发现为临床治疗非酒精性脂肪肝等脂类代谢紊乱相关疾病提供了理论依据。

目前,非酒精性脂肪肝已成为慢性肝病的重要病因,并且缺少有效的治疗药物。团队中的研究人员、东北大学生命科学与健康学院的学生薛晗介绍说,减少膳食中的铁含量、放血疗法等去铁治疗对非酒精性脂肪肝虽然有成效,但这两种办法难以准确控制,使得普通患者难以接受,大规模推广受到限制。

铁螯合剂已经在临床中安全应用几十年,此前主要用于治疗某些机体铁过载的遗传性疾病,如地中海贫血。而此次研究团队开拓了铁螯合剂新的应用领域,为“老药新用”提供了新视点。

根据他们的实验数据,铁螯合剂可减少肝组织的铁沉积,降低氧化应激水平,维持肝脏脂肪代谢及铁代谢的稳态,进而改善肝脏脂肪变性。同时,它还能抑制炎症细胞因子的产生以及肝细胞的凋亡,增加肝组织的适应、再生能力。

除此之外,他们还发现铁螯合剂在减少动物血脂及肝脂肪变性方面具有显着作用。这种相对安全、高效的药物如能快速转入临床应用,将增加2型糖尿病和非酒精性脂肪肝等相关疾病患者的新选择。

东北大学本科团队的成功也彰显了一种新的趋势——科研团队越来越年轻化。这些本科生能给科研带去更多活力和新想法、新思路。牛津大学副校长伊恩?沃尔斯利就曾表示:“科学研究是大学的立身之本。我经常能从同本科生的互动中收获科研灵感。”有人说,出名要趁早,其实科研也是如此。
