J Nucl Med:全新靶点α疗法:对抗癌症更有效!

2017-10-04 佚名 Medicalxpress

德国医学杂志中发表了治疗男性晚期前列腺癌的新选择,这一研究为男性前列腺癌和转移前列腺癌患者带来了新的希望,在研究报告中,科学家指出,他们建立了一个药物剂量锕- 225标记目标,他们把这一疗法成为α疗法,用来对抗前列腺特异膜抗原(PSMA)阳性的肿瘤。

德国医学杂志中发表了治疗男性晚期前列腺癌的新选择,这一研究为男性前列腺癌和转移前列腺癌患者带来了新的希望,在研究报告中,科学家指出,他们建立了一个药物剂量锕- 225标记目标,他们把这一疗法成为α疗法,用来对抗前列腺特异膜抗原(PSMA)阳性的肿瘤。

来自德国海德堡大学医院的研究人员在接受采访时表示:“有针对性α治疗的想法并不是全新的,然而,从数以百计的临床研究报告中得知,这一疗法的临床经验仍非常有限。我们目前的结果是针对这一疗法的临床验证,这一研究可谓是前列腺疗法的里程碑,因为我们可以通过临床试验将新疗法应用于人类。”

在临床试验中,结果显示晚期前列腺癌对新疗法的反应敏感性,此外,试验结果确定重复治疗8周可以持续控制肿瘤。

研究人员指出:“我们发现了一种治疗平衡,那就是治疗毒性与抗肿瘤活性之间的权衡,只有达到这种平衡,才能完成抗癌的最佳效果。然而,我们现在的结果只有一个起始剂量。一方面,仍有待优化;另一方面,需要进一步的研究来评估其有效性。最终,会有一个新的治疗方法改善晚期前列腺癌患者症状或延长他们的生存期。”

目前,第一阶段的临床试验已经结束,接下来,研究人员将开启第二阶段的临床试验,找到更加精准的用药剂量。

Cancer Discovery:研究人员确定靶点“PPT1”,为癌症患者带来了希望

宾夕法尼亚大学(UniversityofPennsylvania)的研究人员开辟了一条与癌症抗争的新途径,他们找到了一种方法来锁定一种对肿瘤生长至关重要的酶,同时也阻断了过去试图将这种酶用于治疗的机制。研究人员能够利用这一发现开发出一种药物,成功地抑制了黑色素瘤的生长,以及在小鼠体内的胰腺和结直肠癌。《癌症研究》杂志本月在网上公布了这一发现。

科学家发现21种全新潜在药物靶点

来自瑞典的科学家在8月的《科学》杂志上发表文章,通过对9,666人的基因测序的研究,分析17种癌症的转录组学、蛋白质组学和临床数据,得到了人类癌症病理学图集。

Cell Rep:研究发现让脂肪燃烧的靶点

在我们的身体里有好脂肪和坏脂肪。好的脂肪有助于燃烧卡路里,而坏脂肪则会贮藏热量,导致体重增加和肥胖。近日,华盛顿大学医学院的新研究已经在小鼠身上确定了一种将坏的白色脂肪转化为好的棕色脂肪的方法。这项发表在9月19日Cell Reports期刊上的研究有望用于开发更有效的减肥方法。

Gut:关乎上亿肝病患者,中国研究人员参与发现阻断肝硬化新机制,填补领域空白!

目前来说,肝移植是慢性肝病的最终治疗手段,但是供体短缺又是它的一个阻碍,因此广大患者极其迫切地需要能控制甚至逆转肝纤维化的药物。不过,发表在胃肠肝病学顶级期刊《Gut》上的研究成果也许将填补这一“空白”,一组研究人员发现了一个重要靶点的作用机制,抑制它可以阻止甚至逆转肝纤维化

北京大学药学院屠鹏飞团队揭示中药作用新靶点

在国家自然科学基金项目等资助下,北京大学药学院天然药物与仿生药物国家重点实验室教授屠鹏飞团队研究揭示了传统中药苏木的抗神经炎症活性成分苏木酮A的直接作用靶点蛋白为肌苷-5-单磷酸脱氢酶2(IMPDH2),相关研究成果在《美国科学院院刊》上在线发表。

Cell:新型NSCLC治疗的靶点被发现

Scripps研究所与辉瑞合作,利用其研发的新方法找到了对非小细胞肺癌(NSCLC)生长非常重要的蛋白质的小分子抑制剂。非小细胞肺癌在肺癌患者中占据了85%的比率,是一种较为高发的肺部癌症,而且研究表明这种疾病对药物治疗相对不敏感。 这一研究成果公布在9月28日的Cell杂志上,由Scripps研究所分子医学系教授兼联合主席Benjamin F. Cravatt研究组历时多年完成。对于这项新成果
